Android: Limit Google apps with FOSS alternatives

What if you don’t want to run Linux on your smartphone or your device is not supported, but still want to have (some) control over your apps and data? This is another incomplete :upside_down_face: Android tweaking guide, focused on replacing pre-installed/popular apps with powerful open-source alternatives.

If you have already used F-Droid before, you can skip this paragraph. F-Droid is an app that works as a catalogue of apps, similar to Google Play. You will not find it in Play, you have to download it from the official website and install it, similarly to installing a program in Windows. After that, you can browse and install apps the convenient way. The difference is that everything in there is open-source and ad-free, designed for privacy-conscious users. :love_you_gesture: :v: The following list consists of apps uploaded in F-Droid, but some of them are also available in Google Play.
I have not tested them in all Android flavours and often only some versions are supported; it’s a trial and error process to find the one for each category. If you search for a desired operation you will find a few options to choose between lightness, elegance and practicality. This is a personal-recommendation-list, not a definitely-best-for-you-list.

SMS messaging
QKSMS instead of the pre-installed messaging app.
Tired of Google’s Messages auto-enabling the “Improve Messages” clause that collects your data? You don’t need it. QKSMS supports multiple SIMs and MMS messaging.

Web browsing
Firefox instead of Chrome.
The debate for the perfect browser is out of scope here, but obviously your browser is one of the things you will consider changing. (Yes, there are alternatives to Firefox.)

YouTube browsing
NewPipe instead of YouTube.
NewPipe is a front-end for YouTube, basically YouTube with privacy and without ads. It can also play in the background (!) if you like. Since, PeerTube is not always enough, no matter how substantial.

OpenMultiMaps (based on OpenStreetMap) instead of Google Maps.
Crowd-sourced maps for all countries. Special filters included, like wheelchair accessible places, vegan/vegetarian restaurants and more.

Note keeping
Carnet instead of Google Keep.
Simple but feature-rich notepad.

Hardware monitoring
CPU Info to complement pre-installed system monitoring apps.
Displays hardware specs, current CPU frequency per core, RAM usage, temperatures and more.

Orbot to access the Tor network.
Tor is not really a VPN, but this app works mostly as a VPN. No need for access to specific (paid) servers.

Directory Exploration
Simple File Manager Pro to view and handle directories.
Google’s Files are designed to show only files saved directly from the user. Finding system folders is not that simple. The Simple File Manager belongs to a series of apps for basic operations by Simple Mobile Tools, most of which are worth trying. The apps require a payment in Google Play, so they are not Free anymore. Yet, you can still install open-source versions via F-Droid, without payments or ads.

Chat, Messaging, Collaboration
Unless, you didn’t land here from mastodon, you already know how to survive without Facebook. A few ideas for encrypted communications:
Signal, end-to-end encrypted chat
Telegram, client-server encrypted chat with limited end-to-end encryption capabilities
Briar, peer-to-peer encrypted chat with offline communication capabilities
Riot, chat and collaboration tool based on Matrix with optional end-to-end encryption
Antox for Tox, end-to-end encrypted chat and collaboration tool, now in alpha
Some of those tools require a phone number to set up, making them not ideal for anonymity.


  • Limiting permissions or even disabling remaining system apps might make you feel safer, although some of them are necessary for your phone to function properly.
  • If you still use proprietary apps, you can try Exodus Privacy to monitor their behaviour, or AdAway (requires Root access) to block built-in ads.
  • One step further: try Private Location to spoof your location, Scrambled Exif to remove camera metadata from images and PilferShush Jammer to block apps from secretly using your microphone (my testing was inadequate to prove that these 3 apps actually make a difference).
  • Keep in mind that FOSS from small teams or individual developers will not have frequent updates.
  • You may notice great customization options in many F-Droid apps, as they target demanding users. If you have a passion for Free software, this will not come as a surprise.

What did I miss? :thinking: Feel free to add any app you consider useful to improve this topic.


Wonderful post, thank you!!!


Great post!
For sms I use Silence, which beside being a full featured sms/mms app also has e2e SMS encryption!

I’d add, regarding Newpipe, that is also support peertube, newpipe rocks big time.

I’d add that Telegram has different apps in F-droid and google store, on F-droid is fully open source (and is called Telegram FOSS)


Silence seems awesome! I haven’t heard of it before. It uses Signal’s encryption protocol, how cool is that?!


Wonderful post, thanks. Keep them coming.

I bookmarked it for closer review later a few apps on the list are new to me and I’d like to try them out.
