Cromite has been my main browser, with zero trackers, according to Exodus, and has a sandbox incorporated.

Audile has been my Shazam, and I use RethinkDNS to block some apps. It also has more features.

AntennaPod is amazing for listening to podcasts.

• Browsers

Mull is my go to browser, based on Firefox with proprietary blobs removed and since its Firefox uBlock Origin can be installed

Mulch is chromium based for when websites ~ break ~ with Mull. Both are by the same Dev that makes DivestOS

• Utilities

I’m not really sure what is meant by utilities but these are some apps that I utilise pretty much every day

URLCheck for easily removing tracking from URLs either manually or automatically

Bitwarden is my go to password manager, you can add their repo to your fdroid client to get auto updates

Aegis for 2FA with easy backup and restore to and from files and supports importing files from so many other 2FA clients

Insular utilises the work profile to separate out apps. Some people in my life still use WhatsApp so I have a whole profile just for it, I can’t wait for the DMA to fully kick in so I can get rid of WhatsApp

Librera opens all of my documents for me and I can choose between scroller mode for PDF type stuff or reader mode for ebooks. It also has amoled black which I love.

QbitController to easily manage all of my qbittorrent instances. It also automatically opens magnet links I tap on so I can add them to one of my instances easily

RHVoice TTS that integrates with OSMand, I find I have better voice results with this compared to espeak

Syncthing Fork to auto sync folders on my phone, PC and NAS

Termux terminal emulator I use for SSH, it also runs Zotify and YT-DLP

KDE Connect for controlling my cursor on my PC, quickly sharing files to and from my PC and for seamlessly sharing clipboards between them

• Forgotten Apps

Showly OSS Integrates with trakt(.)tv to keep track of shows and also has a discover tab for TV and movies

Unexpected Keyboard I missed the keyboard discussion so I’m going to mention it here. It supports function keys! So I can use htop in SSH to kill processes on my PC when I break something and my screen freezes

• Aegis 2FA Authenticator

Only saw these megathreads now, thank you for the great work. If you don’t mind I’m just going to past my comment of a recent post with a similar question, but add some more that I use. If you want I can delete it

I use a variety of FOSS tools for both personal and work productivity.

For personal I use:

• Nextcloud (Calendar, sync files, contacts etc, forms, availability sharing)
• Thunderbird (Mail & Calendar)
• Vikunja for managing all my projects/tasks. Also is very useful to have shared tasks with relatives. Another useful feature is that it can share specifics projects to people that do not have an account (for vacancy planning for example)
• Tasks.org to manage Vikunja tasks in Android
• Logseq for managing all my thoughts, ideas, tracking content like books, movies, videos watched
• Nomie (specifically this maintained instance which has some new features). I use it to track myself (mood, anxiety, adhd, symptoms, food and drug consumption, people). It has an API so I for example can automatically insert activities from Garmin API. It is very useful to correlate things in life, or to tell the doctor if a specific symptom has flared up or not and many more things
• Omnivore is my read-later off choice app, replacing Wallabag. It has an EXTREMELY polished interface, can aggregate RSS feeds, supports tags, comments, many filters and more. But the amazing thing is that it has a plugin for Logseq which automatically syncs all my highlights, notes and tags to it
• Ferdium to quickly access all my important services
• Syncthing on my phone, laptops and Kobo to sync Logseq between devices and books/articles from my PC to Kobo
• Liftosaur for exercise routines (it has script language even) and can also track body measurements.
• waistline as a substitute for myfitnesspal or cronometer
• Phoneprofileplus as a sort of Tasker substitute
• Sayboard for speech-to-text keyboard
• Cofi to aid in making the perfect cup of coffee
• Anki for learning things faster. I use a plugin for Logseq to automatically send cards to Anki, and AnkiDroid to access anki on phone
• ActivityWatch has my cross-device time tracker
• FindMyDevice but FOSS

For work use:

• Logseq is my main tool, with the capability of connecting to Zotero, reading papers and taking notes which with queries I can leverage it to see new ideas forming. It also acts as the best logbook I’ve ever used through its powerful templates and queries which simplifies a lot the work of comparing results since it can all be done automatically
• Zotero to manage all my papers
• neovim with vimtex, ltex-ls and ultisnips to write documents in LaTeX very fast. Also have some scripts to manage vector graphics very easily using https://github.com/gillescastel/inkscape-figures
• Inkscape for doing all the images for my papers since I plot my graphs in SVG. This way I can edit graphs after ploting and never lose quality
• Ranger file manager
• Espanso

netGuard of course

and fairEmail

Forgotten apps: Lawnchair(Release) together with Arcticons. Very minimalistic!

FlashDim: dim your Flashlight
Linphone: SIP Phone
Librera FD: Full Featured PDF reader and editor
phyBox: Use your Smartphone Sensors
Pedometer: counts your steps

Honest question. Are there any FOSS Android browsers? I use Mull or SmartCookieWebPreview. Even Mull gets the ‘the upstream code is not free’ on F-Droid.

Obviously Chromium is out, Webviews are just a wrapper for Chromium.

Does that leave anything?

I recently switched from Firefox to Floorp. It is based on Firefox ESR and customizable like Vivaldi. Only downside is, there is no mobile version

How about free and open source money? Bitcoin has been around for 15 years. Some default suggested wallets for users might be worth including in a list of must-have FOSS apps. Many users just use google to find their first wallet and that can send them down some wildly unsafe paths. The more users know about which are the kind of “standard” open source wallets, the less they’ll end up installing some closed-source ‘trust me bro’ nonsense or worse download a wallet which is an actual scam and just steals their funds.

For custodial wallets for Bitcoin I would suggest Strike (supports the most countries) and for non-custodial I would suggest Phoenix. Custodial means the app developer control the keys to access the Bitcoin, non-custodial means you do.

Strike: custodial, most countries of any custodial wallet, can connect directly to bank account/debit card, closed source (I’m not aware of any open-source custodial wallet)

Phoenix: non-custodial, all countries, can’t connect to bank account which means you can’t buy BTC with it, you need a custodial wallet or exchange account to do that. That’s true of all non-custodial wallets.
