Ankidroid— Create, share, borrow and study with flash cards

Firefox— Web browser

Rethink Firewall— Best firewall for android

Infinity— Gonna miss this one (Reddit client)

Libretube— Modern Youtube client using Piped

Obtainium—Keeps track of all my foss apps from their git repositories + them

Gnu IMP— Desktop photo editor

Aurora Store— Download apps from the play store

Bitwarden

Firefox.

Thunderbird Gimp Audacious

• LineageOS: my Android ROM of choice

• LineageOS for MicroG: the ROM on my second phone where I quarantine my use of apps that refuse to work without Google services (mostly stuff I need for business travel e.g. Amtrak, Google Maps)

• Aurora Store: allows installation of most Play Store apps without login. I mainly use this on the MicroG phone, but it's also needed to get the ProtonMail and ProtonCalendar apps (only ProtonVPN is on F-Droid)

• TrackerControl: allows fine tuned domain blocking on a per-app basis. Often allows you to block just ads and trackers but still be able to use an app or at least many of its features.

• Arcticons: monochrome line art icons (because I hate fun and want my GUIs to look like a terminal)

• AsteroidOS Sync: WearOS replacement. AsteroidOS still has a long way to go, but I doubt WearOS would play nicely with LineageOS and I don't want all the tracking anyway.

• Bubble: bubble level by woheller69 (a true F-Droid GOAT)

• FlorisBoard: afaik, only FOSS gesture typing Android keyboard (besides AnySoft, which doesn't seem to work consistently)

• GMaps WV: fairly locked-down web viewer for Google Maps (sadly OSM just doesn't have a usably complete business directory where I live)

• Lawnchair: launcher with all the features I want except being up to date on F-Droid

• Librera: the PDF reader on F-Droid that I hate the least. (Anyone got any better recommendations?)

• NewPipe: ad-free Youtube player with locally stored subscriptions and playlists. An IzzyOnDroid fork with SponsorBlock is also available.

• QKSMS: my SMS app of choice

• Signal: because I can't convince my friends to switch to Briar

• SpoTube: pirate ad-free Spotify that works by looking up tracks on Youtube. Is therefore limited by what's available on YT and sometimes plays wrong tracks, but you can't beat the price :] Even interfaces with a Spotify account to play and edit playlists.

• Standard Notes: E2E encrypted cloud-synced notes. Also accessible by web browser, which has saved my ass a few times while phoneless

• Weather: by BeoCode on F-Droid

• VLC: everyone's favorite traffic cone boi

Emacs, that's all I need!

The list is too long. If I'm forced to choose 5, I guess they'll be,

1. Linux
2. Syncthing
3. Firefox
4. Neovim
5. PhotoPrism

• Quillpad (offline notes)
• MuPDF mini (Great simple PDF reader)
• Unit Converter Ultimate (lots of various conversions)
• Retro Music (fdroid repo for pro version, best music player hands down)
• OSMAnd (Great for fancy mapping features)
• Mull (hardened Firefox with the quickest updates of all Firefox based browsers)
• AntennaPod (best podcast app)
• Obtanium (install apps easily from sources such as Github)
• Droid-ify (better fdroid)

Blender and Firefox for me have always been the apps that have their shit together the most. Both I perceive as insanely complicated pieces of software with a lot of features that work really well and compete with for profit corporations with way more resources.

KDE Connect means that I can ping my phone that's usually presumably somewhere behind my bed or on a counter somewhere, without having to sheepishly walk to the nearest person and ask "can you call my phone I lost it :c"

• Aegis Authenticator
• Antenna Pod
• Unciv
• Shelter

emacs

Antenna-pod if you like podcasts is fantastic relative to google podcasts (but maybe that's a low bar)

My top Must have FOSS app:

• Bitwarden - password manager

Other indispensable FOSS apps:

• FairEmail and Proton Mail - email
• SimpleLogin - email aliases
• Joplin - notes
• Aves Libre - image gallery
• Droid-ify - FOSS app store
• FediLab - Fediverse client
• Medilog - health metrics log
• OctoDroid - GitHub viewer/manager

• LibreWolf (+UBlock Origin, SponsorBlock, and many other extensions)
• Visual Studio Code
• VLC Media Player

• Fedilab for Mastodon (an alternative to Tusky)
• Jerboa for Lemmy
• LibreTube for usable YouTube without an account
• FluffyChat for Matrix (an alternative to Element)
• FairEmail for mails
• Molly for Signal (pretty much the same as the original app)
• Forkgram for Telegram (also pretty much the same as the original open source version)
• Aurora for PlayStore apps
• F-Droid
• Fennec for browsing (the opener version of Firefox)
• Aegis for 2FA (an alternative to Google Authenticator)
• KeePassDX for passwords (an alternative to Keepass2Android)
• OpenKeychain for PGP Keys
• Orbot for connecting to Tor and running a Snowflake proxy
• RethinkDNS as DNS with blocklists, firewall and routing to Orbot via Proxy for all TCP connections
• Tutanota as synchronized calendar
• Osmand~ for navigation (an alternative to Google Maps)
• Transportr for public transport (an alternative to DB Navigator in Germany)
• In general the "Simple ..." apps on F-Droid are also nice

@tiring7616 firefox

The humble grep.

• KDE Connect
• LibreTorrent for Android
• Droid-ify for F-Droid
• Orbot for Android (I use it mainly for running the snowflake proxy)

Blender

Godot

Gimp

Probably the nicest Foss stack for game development.

These two are now the first apps I install on any new device:

• Kiss launcher (simple and fast)
• Articons icon pack

Basically, my approach is to (mostly) prioritize text over icons, and reduce the colors I need to process.

Other apps:

• Brave browser (for YouTube and built-in anti-tracking features.)
• Librera (ebook/PDF reader with lots of features)
• Odyssey (local music player optimized for speed. My library is so large that all the other players were having trouble finding songs.)
• Graph 89 (TI graphing calculator emulator)
• Feeder (RSS feed aggregator)

FairEmail is a great email client. Also everytime I reinstall my phone, I get the SimpleMobileTools line of apps, their apps like gallery or calendar are nice-looking and useful.

Syncthing is the one, I could probably replace any one but this one.

Bitwarden, Signal, Firefox, Sumatra PDF, Standard Notes, andOTP, and VLC Media Player

Some from the ones I use:

• F-Droid
• Fennec (firefox variant that supports custom addon collections)
• K-9 Mail
• Termux (terminal + Linux environment)
• Jerboa for Lemmy
• Wikipedia
