StreetComplete. It's an easy way to improve openstreetmap wherever you are. https://f-droid.org/en/packages/de.westnordost.streetcomplete/

NetGuard Pro - Allows you to see and control traffic from all apps, so you can prevent data flows to 3rd party hosts like the ones from Google or Facebook. The pro edition is paid and necessary, but it's all open source, just not gratis

Aegis Authenticator - open source 2FA authenticator

LibreTube - alternative, privacy-respecting, open source YouTube frontend using the Piped API

Merlin - It's a birding app and can identify birds by picture or by their song.

I use Carnet for simple note taking and Catima as a digital wallet. Wavelet can be used to apply AutoEq to headphones. The presets are generally really good and make smaller and cheaper earphones sound a lot better than they do by default.

Moshidon for a Mastodon client

Droid-ify as a much better fdroid client

Another Notes to plan world domination

InnerTune as a great YouTube music ripping app

Feeder for RSS feeds

Xtra as a Twitch client

Tutanota for email/contacts/calendar

Fennec (or Mull) for a demozilla'd stable Firefox with all tracking/analytics/proprietary stuff removed

Mostly stock AOSP apps from my custom GrapheneOS rom.

Every one of those apps are on fdroid, except the built in stock apps obviously

YouTube ReVanced - YouTube with adblocking, SponsorBlock, and Return YouTube Dislike built-in. There is also ReVanced for YT Music.

NetGuard - Firewall that doesn't need root. Works on system apps too so you can help curb the amount of spying done by system apps and apps that don't need an internet connection to function.

Connect - Most functional Lemmy app I could find (and I literally tried them all). Still not as smooth of an experience as Relay, but /u/DBrady has announced no plans to port it to Lemmy so Connect will have to do.

Stremio - Any show or movie you want from any streaming platform (Netflix, Hulu/D+, HBO, Apple TV, etc.), all in one place. The app runs on TVs too. Requires plugins to work, but costs as little as $3/mo or even free, depending on what plugins you use. You'll never need to subscribe to any other streaming platform.

Splitwise - Easily split bills with your SO/roommate(s). Stop arguing over expenses.

Google Rewards - Answer surveys, get Google Play credit. Paid apps are now free!

Sync for Lemmy!

Listing only things that haven't been listed

• Seal: video downloader that lives in the "share" menu
• Aegis: TOTP/Google Authenticator clone that's open source
• personalDNSfilter: an in device vpn that lets you block websites (mostly ads) (blocks in app ads too for quite a few apps!)

If you absolutely must get something from Google Play, I suggest Aurora Store, which acts as an alternative frontend for Google Play, so you don't have to have GApps installed.

If you have use for command line programs, Termux, a terminal emulator, is a great option, and it also works with root.

For reading eBooks, I also have a recommendation, Librera Reader (but I'll check the OP's recommendation too).

Material Files and Simple File Manager are great file browsing tools. But if you need a file browser for root specifically, I recommend Material Files specifically.

moonlight-android - opensource android application to connect to your NVIDIA gamestream functionality provided by most modern NVIDIA graphic cards

I use it often for streaming my computer from my bed to play tactic/mouse heavy games, but latency wise it's very good if using hardware encoding. Less friction than a parsec and/or steam link setup.

Additionally (though I haven't tried it) there is a server software to emulate the NVIDIA(tm) gamestream functionality for AMD/Intel/etc, giving you an open source and low friction way to setup remote game streaming and/or desktop use https://github.com/LizardByte/Sunshine

Torque. It allows you to connect to your car's OBD2 port via a cheap Bluetooth adapter. From the app, you can read and clear diagnostic codes, setup custom gauges, and log data. It was very helpful when my alternator was dying and when my car was overheating. I don't have voltage or coolant temp gauges.

Since you clearly have an eink android device, what other eink-friendly apps do you recommend? Would love to hear of any.

jtx board - Journals, notes, tasks

OpenTracks - Sports tracker

Öffi - Public transport navigator

ViMusic - Listen to music from YouTube

Joplin is one of the most important apps I use daily on my Android phone. The desktop version for Linux, an Appimage, synchronizes with the shared database used by the Android app. One can use common cloud services or pay a small fee (now about 18 euros/year) for a specific cloud synchronization service (1Gb).

I've started using LibreTube, its a lot like NewPipe, but I much prefer the UI. Check it out! (Its in F-Droid, of course)

X-plore file manager.

Local, SD card, FTP, SFTP, FTPS, DLNA, Dropbox, Google Drive, and about a dozen other cloud storages all in the same place with multiple windows you can switch between so you can easily open two folders in wildly different locations and move files between them as if it was all one big filesystem.

Also let's you host FTP or a webapp from your phone for transfers between other lan devices.

Last.fm to track my listening habits, pretty entertaining

• Tasks.org - To Do lists
• Saber - Handwritten notes and drawing in PDFs
• Les Pas - photo management (Nextcloud based)
• Invoice Ninja - invoicing for business

Autosync for Google Drive - Syncs folders in Google Drive to your phone. I use it for music files.

Revanced, it's the successor to vanced and just as good. I tried newpipe but I didn't like that I couldn't log in among other issues.

DraStic. I like playing older pokemon game roms on it.

Kanji tree, a great way to practice kanji.

Island, let's me use different accounts on apps that don't allow account switching. For example, it lets me access both my regular amazon account for kindle and my Japanese account that I use to buy manga and books in Japanese occasionally, without having to log in and out all the time. It basically clones apps and let's you open the clone version as a separate app, so you can have the same app open twice with different accounts.

AI enlarger. Just an app that does a good job enlarging images. I usually use it for art so idk how good it is for photos, but I imagine it's pretty good. It does an amazing job with art. Better than most other image enlarging programs or apps I've tried, except for one paid one that I tested with the free points you get for signing up, which was still about the same in quality.

Kiwi browser, works like chrome but let's you use extensions on mobile. I usually prefer Firefox but there are some sites or activities where I really want to be able to use certain extensions and Firefox doesn't have the ability to use the equivalents on the mobile browser. I think Kiwi provides privacy options that help with chrome's privacy issues though, but don't quote me on that.

AIMP - best local audio player Stuff - good simple to-do widget Hyperlocal Weather - good for cloud cover, not much else Proton VPN & Proton Mail - VPN is the best free one, mail is secure and well made
