The post below contains a curated and regularly updated list of recommended mobile apps.

All of the apps listed here are open source and free as in freedom. Links provided below will take you to the F-Droid repository, which is a 'store' for open source apps Android apps. Some of the apps listed here are normally paid, 'pro' applications as per Google Play, but because they are open source, the F-Droid maintainers have compiled them for you from source and you can use them for free.

If are looking for an alternative to one of the apps you are currently using, you should look at alternativeTo.

Another great resource to find the answer to the question: "What are the best applications that..." is Slant.

For a comprehensive list of privacy focused apps, loot at PRISM break Android section.

A free and open-source operating system for various devices, based on the Android mobile platform.

If you want microG installed you can also try LineageOS for microG. MicroG requires a patch called "signature spoofing", which allows the microG's apps to spoof themselves as Google Apps. F-Droid is included in our ROM, so you can freely download all the FOSS apps on their repositories. It includes "F-Droid Privileged Extension", which allows F-Droid to install and update apps without the need of user interaction or the unsafe "Unknown sources" option.

For a more seamless transition from a pure Android, it is recommended to start with LineageOS for microG.

The installation instructions are available for each supported device.

You will need the TWRP app to flash a custom ROM to your smartphone.

If you do not want to or cannot use LineageOS, consider using Universal Android Debloater to get rid of all unnecessary bloatware from your Android.

Security & Privacy


An ad blocker that uses the hosts file. The hosts file contains a list of mappings between hostnames and IP addresses. When an app requests an ad, that request is directed to which does nothing. There are options to run a web server to respond to blocked hostnames and to direct requests to the IP address of your choosing. You can download hosts files from the app but it is possible to use your own and to add certain sites to the white- and black-lists.

Requires root: Not necessarily. The hosts files is located in /system which is normally read-only.


Ad blocker for people who for some reason do not want to root their phones. It establishes a VPN interface, and redirects DNS server traffic to it. The VPN interface filters the traffic, only allowing queries for hosts that are not blacklisted.

Because of this it is more battery intensive than AdAway and makes it impossible to use a real VPN to encrypt your traffic.


Say hello to a safer, transparent, and secure Android.

Open: Protects from DNS manipulation typically employed to censor websites, social media, and messaging apps.

Safe: Reveals network activity of installed apps and lets you disable, uninstall, or firewall them.

Secure: First line of defense against spyware, ransomware, and malware that steal personal information and takeover accounts.

Fast: DNS Servers are deployed to 200+ locations world-wide to ensure your internet is as fast and highly available as it can be.

Transparent: Open source and free of any trackers.


App Firewall: Prevent apps from connecting to the Internet.

A firewall blocks any app connecting to the Internet over Wifi or Mobile data. Since most forms of surveillance require the data to be sent the network to a server, firewalling them effectively mitigates the threat (File Managers, Alarm Clock, Calculator are few such examples of apps that do not require any Internet access to function).

Monitoring: Keep tabs on incoming and outgoing Internet traffic.

If enabled, the connectivity (DNS) logs are collected and analyzed. Automated reports flag previously unknown or suspicious connections, and reveal the extent of attempt to steal data by spyware networks. In our tests, around 60% of the traffic is flagged and reported as being initiated by known spyware. Logs generated are made available in near-real time to the user for their own analysis.Content Blocking: Block spyware, malware and more.

Anti-Censorship: The app encrypts your internet connection to Domain Name System (DNS) server run by rethinkdns with presence in our 200+ locations world-wide. DNS servers are the address book of the internet: A DNS server provides the exact addresses you need to visit a website or open an app.

However, it is common to alter responses sent by DNS servers to block access or redirect to fake websites. By encrypting the connection to DNS servers on your Android device, rethinkdns helps ensure that the results can’t be manipulated, so you can safely access the internet.

Features: - It is free and open source - It has material design (and a nice UI) - It doesn't have any useless permissions - It doesn't connect to the internet - It tries to display as much information as possible in the main window - It lists activities, broadcast receivers, services, providers, permissions, signatures, shared libraries, etc. of any app - It can launch (exportable) activities, create (customizable) shortcuts - It can block any activities, broadcast receivers, services or providers you like (requires root) - It can revoke permissions that are considered dangerous (requires root) - It can scan for trackers in apps and list (all or only) tracking classes (and their code dump) - It can generate dynamic manifest for any app - It can be used to view/edit/delete shared preferences of any app (requires root) - It displays your app usage, app storage info (requires “Usage Access” permission) - Apk files can be shared (hence the use of a provider) - It can be used to clear app data or app cache (requires root)

...and other minor features such as uninstalling/enabling/disabling apps, displaying app installation info, opening on F-Droid or Aurora Droid.

It basically combined the features of five or six apps that any tech-savy person is needed to install in order to have a “life”.

To install it, you need to add the IzzyOnDroid Repository in the F-Droid settings.


Magisk is a suite of open source tools for customizing Android, supporting devices higher than Android 4.2. It covers fundamental parts of Android customization: root, boot scripts, SELinux patches, AVB2.0 / dm-verity / forceencrypt removals etc.

Here are some feature highlights: * MagiskSU: Provide root access to your device

  • Magisk Modules: Modify read-only partitions by installing modules

  • MagiskHide: Hide Magisk from root detections / system integrity checks


De-Bloater is an application using the power of Magisk to de-bloat unwanted applications systemless-ly. It easily remove system apps from "/system", "/vendor", and "/product" directories.

De-Bloater requires Root Access and a fully functional Magisk environment, including modules, for proper working. As a result, De-Bloater won't work with other rooting solutions as well as in Magisk core-only mode.


  • Easily remove system applications from "/system", "/vendor", and "/product" directories (Reboot required).
  • Restore de-bloated apps, either individually or as a whole (Reboot required).
  • Includes pre-defined de-bloated scripts (Universal Android and Tomatot debloater).
  • Elegantly designed user interface with an auto-dark/light theme.
  • A lot more.


TrackerControl allows users to monitor and control the widespread, ongoing, hidden data collection in mobile apps about user behaviour ('tracking').

To detect tracking, TrackerControl checks all network traffic against the Disconnect blocklist.
This is the same list, that is used by the Firefox browser.
This reveals the companies behind tracking to users
and allows users to block tracking selectively.
This blocklist also allows to expose the purpose of tracking, such as analytics or advertising.

Under the hood, TrackerControl uses Android's VPN functionality,to analyse apps' network communications locally on the Android device.
This is accomplished through a local VPN server, through which all network communications are passed, to enable the analysis by TrackerControl.
In other words, no external VPN server is used, and hence no network data leaves the user's device for the purposes of tracker analysis.


Warden is a FOSS app management utility.


  1. Free/Libre software - Has GPLv3 License
  2. Beautiful design - Based on latest material design guidelines
  3. Detects Trackers & Loggers across whole device
  4. Allows to disable all trackers/loggers
  5. Advance profile based app de-bloater

Warden has a static curated list of known trackers (Exodus Privacy) , each app's dex file is read to retrieve the class names, these class names are then matched with the signatures of known trackers & loggers to find them.

A list of currently known trackers & loggers can be found here & here

Loggers in the context of Warden means all utilities which are used to log user activity on an app or logcat in general. Not all loggers are evil. But few logging tools like ACRA, xLog are very powerful tools that can send user data to devs without user's consent. So do read the app's Privacy Policy, beforehand.

Warden uses su pm to manage the components.

De-Bloater (Requires Root):

Warden provides a profile based de-bloater where a profile is created in a format specified as in this sample scripts You need to place this profile/your custom profile at ExternalStorage/Warden/Profiles to make them appear in app.

De-Bloater is an experimental feature, will improve it over time. Default action for debloating is 'disable' you can configure it to 'uninstall' or 'hide' from settings.

Nuke it! (Requires Root):

Nuke it! is another experimental feature that scans all apps on the device and disables all know tracker components automatically. It also gives an option to export components names per-app basis.

Components here means: Activities, Services, Providers & Receivers

To install it, you need to add the IzzyOnDroid Repository in the F-Droid settings.


Shelter is a Free and Open-Source (FOSS) app that leverages the “Work Profile” feature of Android to provide an isolated space that you can install or clone apps into.

Shelter comes with absolutely no advertisement / statistics / tracking SDKs bundled with it. All source code is available in this public Git repository and the sources are licensed under WTFPL.

This app depends on your Android system’s implementation of Work Profile. Some vendor / custom ROMs may have a broken implementation that may cause crashes and even bricking of your device. One such example is MIUI from Xiaomi. I currently provide no support for such ROMs because I personally do not own any of these devices. If you are running Shelter on these ROMs, you are on your own. If any developer out there own these devices and could make Shelter run on these ROMs, please send pull requests and I’ll be happy to merge them.

=== Features / Use Cases ===

* Run “Big Brother” apps inside the isolated profile so they cannot access your data outside the profile
* “Freeze” (disable) background-heavy or seldom-used apps when you don’t need them. This is especially true if you use apps from Chinese companies like Baidu, Alibaba, Tencent.
* Clone apps to use two accounts on one device

=== Caveats ===

Shelter is not a full sandbox implementation. It cannot protect you from:

* Security bugs of the Android system or Linux kernel
* Backdoors installed in your Android system (so please use an open-source ROM if you are concerned about this)
* Backdoors installed into the firmwares (no way to work around this)
* Any other bugs or limitations imposed by the Android system.

Also, Shelter cannot create more than 1 work profile on one Android device, and cannot co-exist with any other apps that manages a Work Profile. This is due to the limitations of the Android system, and I can do nothing about this.

EDS Lite

EDS allows you to store your files in an encrypted container.

  • Supports VeraCrypt(R), TrueCrypt(R), LUKS, EncFs container formats.
  • Choose among different secure ciphers.
  • Encrypt/decrypt any kind of file.

  • You can quickly open a folder (or file) inside a container from the Home screen using the shortcut widget.


Cryptomator makes your cloud storage trustworthy. The app encrypts files on your mobile device before they are uploaded to your cloud. Even if a third party gained unauthorized access to your files (e.g., hacker attack), your files are secure from prying eyes.


Cryptomator has been developed with a strong focus on user-friendliness.

  • Simply create a vault and assign a password
  • No additional account or configuration needed
  • Unlock vaults with your fingerprint*

* from Android 6.0 and smartphones with fingerprint sensor


Cryptomator is compatible with the most commonly used cloud storages and available for all major operating systems.

  • Compatible with Dropbox, Google Drive, OneDrive, and WebDAV-based cloud storage services
  • Create vaults in Android’s local storage (e.g., works with third-party sync apps)
  • Access your vaults on all your mobile devices and computers


Cryptomator for Android is based on the solid open-source foundation of Cryptomator for Desktop.

  • File content and filename encryption with AES and 256 bit key length
  • Vault password is secured with scrypt for enhanced brute-force resistance
  • Vaults are automatically locked after sending app to background
  • Crypto implementation is based on the open-source library CryptoLib and is publicly documented

To install it, you need to add the IzzyOnDroid Repository in the F-Droid settings.

Private Location

A simple app to set your location to anywhere in the world, and improve general phone location privacy.

Apps on your phone can require location permissions to work, and make repeated and unnecessary location requests in the background throughout the day.

Setting your location somewhere else will help protect your privacy when using these apps.

This is one of the few location apps that doesn't rely on Google Maps.


Privacy Friendly Net Monitor monitors active network activity and provides information on the scanned connections and apps. The Connection's local and remote socket information is displayed along with a resolved hostname information and protocol evaluation based on well-known ports. Known un-/encrypted protocols are automatically marked. This app belongs to the Privacy Friendly Apps group developed by the SECUSO research group Universitat Darmstadt, Germany.


UntrackMe once set by default to open Twitter and YouTube links will transform them into Nitter and Invidious links and delegate the action to another app.

It also supports Google Maps links to transform them into OpenStreetMap links or Geo URI.

The app will detect shortened URLs and will display the full URL before visiting the site.

When sharing a Twitter, YouTube or Google Maps link just pick up UntrackMe to transform it before sharing it with another app.

Available also as a Lite version.

The full version embeds everything that the lite version supports, but will also handle all other links to stripe utm/tracking parameters. As an edge effect, it uses its built-in app picker (which allows to display the full URL before visiting it) for delegating the action.

The lite version handles YouTube, Twitter, Instagram, Google Maps and some shortener services to transform these links. It uses the default app picker from the device.


The main function of Finder is to send the location of the smartphone it's installed on when requested. It also has a "tracker" feature (it can’t be activated remotely, only manually). The application is designed to search for missing people or stolen phones. SMS is used for communication because Internet connectivity may be not available. The app has two ways of determining the coordinates: using GPS (gps must be enabled in system settings, or special permission granted via ADB for auto-enabling), and using mobile and WiFi network info.


This is a fork of Syncthing that brings major enhancements like:

  • Individual sync conditions can be applied per device and per folder
  • Recent changes UI, click to open files.
  • "Battery eater" problem is fixed.
  • Android 8 and 9 support.

Syncthing replaces proprietary sync and cloud services with something open, trustworthy and decentralized. Your data is your data alone and you deserve to choose where it is stored, if it is shared with some third party and how it's transmitted over the Internet. Syncthing-Fork for Android is a wrapper for Syncthing that provides an Android UI instead of Syncthing's built-in Web UI. Goals of the fork:

  • Develop and try out enhancements together with the community.
  • Release the wrapper more frequently to identify and fix bugs caused by changes in the syncthing submodule
  • Make enhancements configurable in the UI, users should be able to turn them on and off

Comparison between upstream and fork at the time of writing this:

  • Both contain the syncthing binary built from the official source at GitHub:syncthing/syncthing
  • Syncing functionality and reliability depends on the syncthing binary submodule version.
  • Fork gets along with upstream and sometimes they pick up my improvements.
  • Strategy and release frequency is different
  • Only the wrapper containing the Android UI is addressed by the fork.

Element is a new type of messenger and collaboration app that:

  1. Puts you in control to preserve your privacy
  2. Lets you communicate with anyone in the Matrix network, and even beyond by integrating with apps such as Slack
  3. Protects you from advertising, datamining and walled gardens
  4. Secures you through end-to-end encryption, with cross-signing to verify others

Element is completely different from other messaging and collaboration apps because it is decentralised and open source.

Element lets you self-host - or choose a host - so that you have privacy, ownership and control of your data and conversations. It gives you access to an open network; so you’re not just stuck speaking to other Element users only. And it is very secure.

Element is able to do all this because it operates on Matrix - the standard for open, decentralised communication.

Element puts you in control by letting you choose who hosts your conversations. From the Element app, you can choose to host in different ways:

  1. Get a free account on the public server hosted by the Matrix developers, or choose from thousands of public servers hosted by volunteers
  2. Self-host your account by running a server on your own hardware
  3. Sign up for an account on a custom server by simply subscribing to the Element Matrix Services hosting platform

Why choose Element?

OWN YOUR DATA: You decide where to keep your data and messages. You own it and control it, not some MEGACORP that mines your data or gives access to third parties.

OPEN MESSAGING AND COLLABORATION: You can chat with anyone else in the Matrix network, whether they’re using Element or another Matrix app, and even if they are using a different messaging system of the likes of Slack, IRC or XMPP.

SUPER-SECURE: Real end-to-end encryption (only those in the conversation can decrypt messages), and cross-signing to verify the devices of conversation participants.

COMPLETE COMMUNICATION: Messaging, voice and video calls, file sharing, screen sharing and a whole bunch of integrations, bots and widgets. Build rooms, communities, stay in touch and get things done.

EVERYWHERE YOU ARE: Stay in touch wherever you are with fully synchronised message history across all your devices and on the web at

Briar is a messaging app designed for activists, journalists, and anyone else who needs a safe, easy and robust way to communicate. Unlike traditional messaging tools such as email, Twitter or Telegram, Briar doesn't rely on a central server - messages are synchronized directly between the users' devices. If the Internet's down, Briar can sync via Bluetooth or Wi-Fi, keeping the information flowing in a crisis. If the Internet's up, Briar can sync via the Tor network, protecting users and their relationships from surveillance.

Great app with two significant drawbacks:

  • it does not offer file transfer
  • it does not have a desktop app

And one minor drawback:

  • it does not allow voice and video connections, only text messages

If those problems above are resolved (and there are plans to do do it), it may be the most secure and private 'chat app' out there.

Differences to NewPipe:

With NewPipe, the extraction is done locally on your phone and all the requests sent towards YouTube/Google are done directly from the network you're connected to and doesn't use a middleman server in between. Therefore Google can still access information such as the users IP address, besides that subscriptions can only be stored locally.

LibreTube takes this one step further and proxies all requests via Piped (which uses the NewPipeExtractor). This prevents Google servers from accessing your IP address or any other personal data. Apart from that Piped allows syncing your subscriptions between LibreTube and Piped which can be used on desktop too. If the NewPipeExtractor breaks, it only requires an update of Piped and not LibreTube itself, therefore fixes usually arrive faster than in NewPipe.

While LibreTube only supports YouTube, NewPipe also allows using other platforms like SoundCloud and Both are great clients for watching YouTube videos, it depends on the individuals use case which one fits the own needs better.

Frost for Facebook

Note: First of all, you should not use Facebook! This is inly for people who for some reason need FB.

Frost is a fully functional web wrapper, with many unique and native features such as:

True multi user interactions - More than just an option in a settings menu, Frost's account switcher is right in the drawer. You are one tap away from switching accounts, and everything refreshes on the switch so that you can view other accounts instantaneously. Furthermore, the notification service will fetch notifications from all accounts, and will let you know which account has the new notification.
Better multitasking - Frost contains an overlaying web browser that can be drawn on top of your foreground task. Open links and notifications with a full screen view, then swipe away to get back to your previous task.
Contextual awareness - Frost integrates additional features via long presses. Need to copy a block of text or share a link? Long press the text. Need to zoom into an image or download it? Long press the image!
Material Design - Built for lollipop and up, Frost focuses strongly on a beautiful and functional UI, and embraces material transitions and dimensions.
Complete theme engine - Frost contains very comprehensive themes that customize all components of the app. Frost is also the only app to support transparent themes.
Fully opened - Nothing speaks for privacy more than being open sourced. Frost is proud to be one of those apps, and can be found on github (Link in the app's about section)
Fixes the little things - Frost is community driven, and many tweaks are added to address minor inconveniences and give a full native experience, despite being a web app. To list a few:
   • Focusing on a text input will prevent refreshing, so you don't accidentally swipe and lose your progress.
   • Horizontal swipe can be enabled along side the viewpager swipe with a simple long press
   • Automatic bug reports are sent when a crash is detected, so even if you don't contact the devs, you are helping contribute by using the app.

Mandatory permissions used and why:

• Internet, Network State, Wifi State - Frost fetches the pages from Facebook's mobile website. It also needs the network state so as to limit internet usage when you are on a metered network.
• Receive Boot Completed - Frost notifications persist on reboot, and need this permission to be added each time.
• Vibrate - Needed to vibrate phone for notifications; this can be toggled in the settings
• Billing - For purchasing pro and unlocking all of Frost's features

Optional permissions used and why:
(these are only requested when they have to be, and are disabled until then)

• Read/write external storage - Needed to upload photos in a new status and save photos when prompted
• Fine/coarse location - Needed for the check in option if users wish to search for their location

• That's it! No privacy intrusion and no extra demands.

Permissions NOT used and why:

• Wakelock - Frost takes advantage of Android's Job Scheduler, and lets the framework decide when to run background services. Frost therefore doesn't need to constantly run in the background, nor does it force your phone to stay awake.
• Retrieve running apps - Frost has no need to access external apps or see what else is running
• Identity - Frost manages its accounts internally and uses it solely to give you access to your account. We don't depend on other personal information and we don't even save your email.
• Camera - While the camera permission can be added to allow you to directly take photos and upload them, we've decided that it would be best to allow you to do so externally and then share the photo with Frost


Simple yet advanced Instagram client


  • Login NOT NEEDED to browse timeline and face-tagged posts from public profiles, hashtags, and locations.
  • View & download posts.
  • View & copy comments, captions, & biographies.
  • Zoom in on pictures with ease.
  • Batch download posts from feeds (Hold & Select).

  • View stories anonymously (by default, configurable).
  • See your own liked & saved posts.
  • Copy DM messages & download attachments.
  • Switch between accounts.

Extra merits:

  • Prevents irrational decisions: Instagram likes are set-it-forget-it, allowing them to collect more data from you. Barinsta intentionally removes double-tap and requires you to click into posts to give it a like. Barinsta also allows you to easily access posts you've liked through your own profile.
  • Allows customization: Pick your themes and layouts!
  • Allows viewing at your own pace: No need to "hold" a story with your fingers!
  • Not a webapp: Absolutely NO browser involved, except for login.
  • Not a mod: Absolutely NO dependency of the actual Instagram app.
  • We don't store passwords!
  • Request what you want: The app only requests what it needs to show you the content. No communicating with useless endpoints, and only minimal data is sent to Instagram.

But it does not have to be used in emergency situations only - it can be also useful for trips to the outdoors, hiking, camping, learning about nature and yourself truly. This is not only fun, but you can also train skills (make fire, build shelter, ..) you might need in a catastrophy. Some things work best with practice in a relaxed environment - then you also have time for some experiments.
