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.
The ability to insert flow charts on the go with the draw.io integration built in is amazing for technical documentation.
I’m a big fan of Bookstack. The Docker images work great, also in Kubernetes. SSO is easy to set up as well, so if you’re using something like Authentik for SSO, you can integrate it pretty easily.
By default it uses a WSYWIG editor, but you can change the default to Markdown. Also, the ability to use the built-in draw.io diagram tool is great if you are documenting anything like code paths or network setup.
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.
