I use KDE Connect as a media remote and to transfer files between my phone and computers. It has quite a few other functions, like remote mouse control, sms, seems to share clipboards as well.

https://kdeconnect.kde.org/

All of these list are great as we discover new apps each time.

But, I would suggest to write what is the app about.

Obtainium is great for updating apps hosted outside the playstore, big upside being you don't need to bother with FDroid releases

Great lists so far. I'll add one that I picked up from a previous thread:

URLCheck

URLCheck acts as an amazingly customizable and powerful intermediary when opening url links, allowing, among other things: to remove trackers, affiliate links, unnecessary elements, check Hosts, facilitating link holding and sharing, protecting against certain phishing techniques and many more...

• Acode - code editor
• Auto-Auto-Rotate - remember rotation lock settings by app
• Auxio - there's a million music players, this one scratches my itch just right
• Binary Eye - bar/QR scanner
• BreezyWeather - appears to have sources globally
• Collabora Office - view & edit libre/Microsoft office files
• Missed Notifications Reminder - I need a repeating audio notification so I don't miss important work related messages
• MJpdf - pdf reader
• Mull - privacy enhanced Firefox
• RoMote - roku remote on your phone
• Skymap - what is that thing in the sky?
• Snapdrop - share with other devices via snapdrop.net (crashy) or pairdrop.net (better)

If you use Organic Maps you may be interested in https://streetcomplete.app to help fill out the map

• Privacy Browser: a browser based on WebView
• Simple Calendar Pro: for managing my self-hosted CalDAV (waiting for Fossify's version)
• Fossify Gallery: managing my images and videos
• AntennaPod: listening to podcasts
• Bitwarden: managing my self-hosted vaultwarden

• Simple Voice Recorder: letting me record stuff when I don't have my audio recorder with me (waiting for Fossify's version)

FeedMe (Not FOSS. Open to suggestions)

The RSS or meal planning app? If it's the former I like Feeder. You can probably export and import all your feeds.

I think some of my favorites are LibreTorrent, Session, and NewPipe.

I am a big fan of open source engine recreations, even if I don't play them a ton, so DevilutionX and OpenMW are worth mentioning. I think Xash3D is also open source if you want to play Half Life on the go.

I think OpenRCT2 has an Android app but I haven't bothered figuring out how to set it up yet.

I use Feeder for RSS. Quite a good, constantly improving app. :)

For keyboard I'm currently using OpenBoard and ThumbKey, the latter obviously not for everyone.

Adding to your list:

• Droidify
• Trail Sense
• NewPipe
• Logseq
• Syncthing
• Coffee
• Element
• Cryptomator
• VLC
• Geometric Weather
• Termux
• Noteless
• StreetComplete
• Translate You

FairEmail

Obsidian is Open Source? I switched to Logseq because it wasnt open source. A friend wasnt even allowed to install it on his Work PC becauze Obsidian wants 50€ per Year when not used at home privately.

Can share some of my favourites

• KISS laucher
• Floris Board (keyboard, which I love to use)
• Bitwarden + Aegis (password manager + OTP)
• Eternity (for browsing lemmy)
• Mull (hardened firefox fork)
• Organic maps (maps + directions)
• Track & Graph (for tracking trends/habits)
• WebApps (running sandboxed websites)

Just begun exploring using:

• Immich (selfhosted photos solution)
• ReThink (local dns/firewall tracking blocker)

Btw, I believe Obsidian isn't FOSS.

Aurora store
Organic maps
PDF viewer

Openboard (though seems dead and looking for alternative)

5. Chip Defense. A little FOSS tower defense game.

6. KDE Connect. Tool to transfer files to another device, or vice versa.

7. Trail Sense. Nice lightweight app that does a variety of things, but I mostly use it for white noise.

8. Organic Maps. I try to use it instead of Google Maps whenever possible.

9. FitoTrack. Amazing app to keep logs of your workouts, or motorcycling trips as I use it. Shows you where you went, how fast you want, and how many calories burned where applicable.

Edit: Tried to count down from 5 to 1 as this is my top 5 apps from F-droid, but the auto bullet thing is counting up instead

I love Thumb Key, it's a very unique and actively developed keyboard app.

I use a few apps from the SimpleMobileTools suite. They aren't full FOSS, they have basic and pro versions where the basic version is GPL3 and the proprietary extended features cost a few bucks. The basic FOSS tools are still decent, if barebones.

The suite includes:

• a calculator
• a phone dialer
• a music player
• a calendar
• a photo gallery (with basic editor)
• an audio recorder
• a flashlight
• a clock
• an app launcher
• an SMS messenger
• a camera
• a keyboard
• a note taker
• a file manager
• a contact book
• a simple painting canvas

I use the gallery and file manager the most. Though admittedly I threw a couple bucks their way for the proprietary extensions. It's not FOSS, but if it was going to be proprietary, I think it's one of the fairest deals in software these days. Better than another bloody subscription model, or holding the ad-free experience hostage behind a paywall.

Nextcloud News I like for RSS since it fetches the full text article. Obtainium lkke others mentioned is a must have for me.

We have similar lists, so some considerations:

• Helium314 fork of OpenBoard for keyboard
• Simple Gallery for your gallery (just purchased but there is an emerging fork I'm blanking on the name of)
• Matrix with a Signal bridge so you can use tablets and other devices with Element, which has a wider range of devices
• NeoLauncher is like OL, but with more configuration
• Thunder for Lemmy. Great client, and only one with 2 column tablet support

Here are some not mentioned in this thread yet.

• App Manager - App manager on steroids
• Calculator++ - Have used this calculator forever
• DiskUsage - Storage analyzer
• J2ME Loader - Emulates old JAVA games
• Jellyfin - Client for Jelyfin media server
• PCAPdroid - Network sniffer
• UnicodePad - UTF char explorer

F-Droid, Voyager, Eternity, Libretube

Catima - for saving arbitrary barcodes and stuff that are hard to integrate into other wallets. I keep my local library card in there, and it works wonderfully

Nonocross - fun little game that has zero frills and distractions. Also very responsive on their github to suggestions and improvements

Termux - when I need to get into things from afar, this is how I do it

Box, Box! - Formula 1 news, schedules, standings, etc

Coffee - Sometimes I want to keep the display awake, so this comes in handy

Obsidian isn't FOSS. I highly recommend Logseq but keep in mind they require CLA signing for contributions

Suggestion For OP

OP You should use Florisboard beta it's good and also Obsidian is not open source.

2FAS, Bitwarden, Firefox are my most used FOSS on Android for me.

megladon for mastodon

https://text.tchncs.de/czars-blogs/apps-i-use The blog itself is foss software writefreely

What's FNG? Fluid navigation gestures? Is that FOSS? Can you share a link to the codebase? Can't find it

Seriously guys, no one saying Nextcloud?

• The main app for photo backup.
• Nextcloud Notes for well, notes you can also use from the desktop.
• NC Passwords for well, passwords
• Phonetrack to record your phone to Nextcloud Maps.
• Deck for the Kanban.

Obtainium is pretty good

Anyone uses InnerTune?

I'd recommend Mull instead of Firefox or Fennec (the deblobbed version) since it's hardened.

It's basically a Librewolf analogue for mobile

Authenticator Pro. It's like Aegis but supports WearOS devices, so I can get my TOTP codes on my watch instead of having to get my phone out.

FairEmail. One of the best email clients I've used, across any platform. Highly customizable.

Syncthing for syncing photos to my home server.

Readrops for RSS - connects to my FreshRSS server.

Firefox, of course.
