vim

Firefox

cant choose one because i enjoy using a lot of them:

1. bitwarden
2. inkscape
3. kdenlive
4. nextcloud
5. organic maps
6. signal games
7. shattered pixel dungeon
8. openttd

• Aegis Authenticator
• Antenna Pod
• Unciv
• Shelter

• 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)

• 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

@tiring7616 firefox

Emacs, that's all I need!

emacs

Inkscape for me :)

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.

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

• Feeder - for reading rss feeds, which takes up more of my time than all social media combined
• KeePassDX and Aegis - passwords and 2fa
• Vanilla Music
• Jerboa
• Droid-ify
• Quillpad - note app inspired by google Keep
• SimpleNotes - checklists. I don't like how Quillpad handles checklists.
• Newpipe
• Discreet Launcher
• FFUpdater - installs and updates browsers

Bitwarden-password manager Joplin - notes Kde Connect- laptop connections for file transfer, notifications etc Syncthing- file syncing

All of these are available of F-droid.

I'm beginning to migrate from Windows to Linux, here are some foss apps I use:

• Blender -for 3d modelling
• Godot - Because im working to be a game dev
• Incscape and paint.net - for general raster artwork
• Brave - My primary browser
• VScode - I just prefer C# over godot's built in GDscript (Not to say GDscript is bad its a nice language but I just prefer C# as I used to use unity)

Edit, you said "must have" oops, but still like to share this anyways :))

Bash

• Fairmail
• keepass
• firefly iii
• Firefox
• sumatrapdf

OpenVPN. I can self-host a lot of different things for my own personal internet/cloud thingy - Bitwarden, Pi-Hole, etc; but to actually use it when I'm not home? I either pay for a VPS or I just have a VPN back to my home network. So much becomes possible with that; like I have the contents of my entire NAS at my fingertips even if I'm not home; I can render projects on a VM at home and manage it from my phone, etc.

OpenVPN is, without a doubt, the most important part of my infrastructure.

Here are my go to apps.

• Droid-ify - Fdroid client
• Mull - firefox mobile fork
• KeePassDX - password manager
• Tracker Control - VPN based, blocks trackers for installed apps
• Nebula (F-droid) - DNS based, can be used alongside tracker control
• Infinity for reddit - sad
• FlorisBoard Beta - keyboard but no development update for months now
• Notally - simple notes app
• Simple Calendar - part of simple tools/suite of apps
• Open Camera
• Fair Email - email client
• Moshidon - forked from an app I cant remember, nice material u design and fast
• Arcticons Icons - line icons for your homescreen
• SimpleLogin - create anonymus emails and disable them, helps prevent spam and address privacy control
• Tutanota - mail app for tutanota
• Jerboa - lemmy client
• Paisa - expenses manager app
• My Expenses - expenses manager app
• ExifEraser - removes metadata for the pictures

Blender

Godot

Gimp

Probably the nicest Foss stack for game development.

• Syncthing - for sycing what pretty much amounts to /home between my mobile and laptop
• Bitwarden - password manager
• ProtonVPN - VPN
• Trail Sense - Hiking tools, most frequently for barometric readings
• Proton Mail - email
• Coffee - keeps the screen on through a button in my notifications. Mostly used when cooking for recipes
• NewPipe - YouTube and downloading
• Droid-ify - Better UI for fdroid
• Aegis - OTP manager
• VLC - needs no introduction
• Kore - remote for Kodi
• Geometric Weather - simple weather app
• Noteless - markdown notetaker. I've mostly moved everything over to Obsidian, but I like my grocery list here still...

Some more I did not see others mention. For Linux:

• Geany
• Python
• Meld
• Nextcloud
• Reminna and TightVNC
• Thunderbird
• Zim

For Android:

• Just Weather
• Joplin
• OpenSync
• Tasks
• OSMAnd
• Nextcloud
• SMSBackp
• Connect Bot

I also recommend the site: https://alternativeto.net/ . You can just search and it will tell you the most used FOSS apps in any category you want.

Firefox, LibreTube, Kaiteki

Firefox.

Also:

Thunderbird Gimp Audacious

Calibre-Ebooks managment Libre Office- instead of MS Office Bitwarden- password manager Mozilla Firefox- browser IceCube, Pixefed app and Mlem for Fediverse Joplin- notes BookPlayer app for Audiobooks Nextcloud for storage

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.

• Signal

• vinyl for music

• AnkiDroid for flashcards. I use it for languages, but i believe there are repositories for other subjects.

• Tachiyomi for manga

-personal Dns filter for blocking ads system wide

-Aegis for two factor authentication

-NewPipe x Sponsorblock for youtube

-Fritter for Twitter without an account

-Librera for reading my ebooks

-Feeder for RSS

-Quillpad for a Google Keep like local alternative

Joplin, Aegis, Bitwarden

Firefox
Nextcloud
Home Assistant
Bitwarden
Tusky
Jellyfin
Pihole
Jerboa
As well as several others that I can't think of at the moment.

I will go with (neo)vim. Must have for me, use it for everything imaginable, writing emails,code, notes ...

NewPipe and FireFox, at minimum.
