  • FairEmail

    Fully featured, open source, privacy friendly email app for Android

    For a mail app, I would suggest FairEmail – a FOSS and privacy focused mail application with many great fearures. I use it everyday and must say that I’ve never used a better Android mail client than this one. The app is available on F-Droid, PlayStore (which obviously isn’t an option for a FOSS phone) & GitHub, for more info see

  • koler

    Just a phone app.

    Check out Koler on F-Droid

  • Appwrite

    Appwrite - The Open Source Firebase alternative introduces iOS support. Appwrite is an open source backend server that helps you build native iOS applications much faster with realtime APIs for authentication, databases, files storage, cloud functions and much more!

  • davx5-ose

    DAVx⁵ is an open-source CalDAV/CardDAV suite and sync app for Android. You can also access your online files (WebDAV) with it.

    In order to sync contacts and calendars: DAVx5 (

  • Seedvault

    A backup application for the Android Open Source Project.

    I can understand the OS/theme being custom, I was mainly joking about the device colour. Anyways as an app suggestion I was thinking maybe SeeVault. LineageOS comes with it baked in as a GDrive alternative.

  • GmsCore

    Free implementation of Play Services

    You should consider using the MicroG project to replace Google Play Services.

  • Camera

    Modern camera app focused on privacy and security with QR & barcode scanning.

  • Android

    DuckDuckGo Android App (by duckduckgo)

  • InfluxDB

    Access the most powerful time series database as a service. Ingest, store, & analyze all types of time series data in a fully-managed, purpose-built database. Keep data forever with low-cost storage and superior data compression.

  • hardened_malloc

    Hardened allocator designed for modern systems. It has integration into Android's Bionic libc and can be used externally with musl and glibc as a dynamic library for use on other Linux-based platforms. It will gain more portability / integration over time.

    Sandboxed Google Play services from GrapheneOS would be far better. They act as a regular app with no greater permissions than a user-installed app.

  • Vanadium

    Privacy and security enhanced releases of Chromium for GrapheneOS. Vanadium provides the WebView and standard user-facing browser on GrapheneOS. It depends on hardening in other GrapheneOS repositories and doesn't include patches not relevant to the build targets used on GrapheneOS.

    I know you said you don't really want Chromium but i'm using Vanadium for years and i've been very happy with it:
