I have quite a few on my phone. Here they are by my folders:

Communication

• Zoom - The ubiquitous teleconference app. This is a weird one to include, but I do pay a subscription for the pro features.

Creativity

• Artflow - Probably the best drawing app on Android. It's certainly the best native app.
• BoxySVG - This is a PWA, but it works pretty well on Android devices with pen support.
• Lumafusion - Video editor. Definitely the most professional of the choices available.

Development

• Acode - For quick edits to my web apps on my Galaxy Tab or through Dex on my phone.
• Go Compiler - For golang tinkering...

Entertainment

• Podcast Republic - Best app I could find that works well on tablets and foldables.
• Scribd for Samsung - Ebook & Audiobook reading service that I subscribe to.
• Inoreader - RSS reader I subscribe to.
• Sync for Lemmy - The only Lemmy app for tablets and foldables.

Files

• Solid Explorer - The best file management app on Android
• FolderSync - Best file syncing app on Android
• Download Navi - Download manager. It's ok.
• Flud+ - Torrenting app.

Finance

• Bluecoin - Good way to manage finances on the go.

Productivity

• Sesame Search - Quicker to get around the OS.
• Tasker - the automation app
• Boosted - Time tracker
• Mondly Language - Language learning

Utilities

• Adguard - No ads.
• Surfshark - For gps spoofing.

Writing

• Atticus - PWA novel writer.
• Jotterpad - Shortform writing app. Used to be subscribed, but I also own the one-time purchase.
• Nebo - Handwriting notes app that converts to text.
• Noteshelf - Good notes app that I sometimes use.

I have a bunch of games and watchfaces, too.
