Yeah, it’s on the Apple app store, and the Android version is available directly from their GitHub release page as an APK, or on F-Droid.

Logseq has an iOS app here, and an Android app at their GitHub releases.

Definitely more. It’s geared to note taking, with hashtags, wiki-like linking, and loads of other features. The main page is here.

I’m a big fan of Logseq. I use Syncthing to sync a folder between my desktop and phone and it works great. Tagging, everything is in markdown, and it’s easy to navigate around.
