Free and Open Source Software

Assuming I'm using Android:

• Mull or Fennec
• SkyTube
• Tusky
• Jerboa
• UntrackMe
• Orbot
• SicMu Player (or any good music player app)

Recently id say OsmAnd~. GPX tracks are great for long bicycle trips and the drinkng water overlay is a lifesaver!

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

Firefox
libre office
obs studio (free, not 100% sure if os)

Joplin, Aegis, Bitwarden

For me it's ViMusic. I was stuck with a shitty Spotify subscription that I couldn't afford until I found Vi. It has pretty much all the bands I like and it passed my moms rigerous examination (she listens to all of of really obscure stuff) so when her Amazon subscription ran out, I got her to start using that instead. Suck it jezzy b!

Osmand - I use this along Google maps, but it's nice to have entire regions downloaded and it shows more information than Google maps, specifically for back country stuff where you need to see every type of trail

Home Assistant

Wireguard - I love that the protocol is lightweight and secure, makes it really easy to access my home network without needing to expose self hosted stuff to the internet

Bitwarden - self hosted with vaultwarden/SQLite, changed my life and it's really easy to share logins with my partner

Immich - self hosted, the first real replacement for Google photos I've found. It has autobackup and it's really easy to share albums.

Kiss Launcher - I like how simple it is. My home screen ends up disorganized anyway so it's honestly just faster to have a recents list and a quick search feature.

Neovim and Guake or Yauake for terminal emulation are both necessary for me.

jtx board for tasks and notes

Firefox.

Also:

Thunderbird Gimp Audacious

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"

• 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)

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

• Mull

• K-9 Mail

• LibreTube

• Quillpad

• Droid-ify

Xtra is my favorite android twitch app nowadays. Twire is also a good alternative. Both are on F-Droid.
