Considering "top" as meant to be "most used", I'd say:
- Voyager, which I'm using right now, a Lemmy client.
- Tusky: a Mastodon client.
- Mull: Firefox fork.
- Firefox (yeah, I have two Firefox installations)
- Sketchbook: a drawing app, I even paid for the additional features.
- Google translate: when I don't remember how to say something specific in English, or when I want to experiment with multiple languages, especially Latin (and Google translate is the only translator app to have Latin support)
- Noto (I was previously using Notesnook): text editor with folder capabilities. I use it to write poetry, free from distractions
- Acode: source code text editor. I use it to create Node.js snippets which I run with...
- Termux: a kind of a "Linux emulator", it emulates a terminal environment within Android with additional programs compiled to arm architecture. One of those programs is Node.js (both the REPL, the runtime and the npm package manager)
