Open source Android diagram, tree or mind mapping software. (lemmy.ml)

Hi all, I really like the open source Linux application called DIA it's a diagram tool that handles flowcharts beautifully.

I'm trying to find an offline Android application that is similar to that, that I can use locally on my Android tablet.

Other software categories that might work include mind mapping, but anything like that really is what I'm after.

There seems to be a severe lack of this, I can't really find anything. I used to use freemind on Linux also, again a great application, but nothing seems to be available for Android.

If anyone has any suggestions, I would love to hear them. Thank you.

Thank you.

Unfortunately, as far as I can tell the only actual open source tool, was mermaidjs, but when it loads it says "Code editing not supported on mobile. Please use a desktop browser."

This is the problem faced. I just can't seem to find anything that's on device / local, open source, and Android.

Mermaid works with Excalidraw and Obsidian. :) Actually all 3 work together on tablets/mobile, using plugins into Obsidian. You can always self host Excalidraw too, but the plugin is far easier.

Thank you. I just loaded obsidian, installed Excalidraw. The issue I can see, is the nodes don't link so you can drag them around. Maybe they can, but the interface is so small I can barely see it. I'll try on my tablet later and see if I can get it to work. Mermaid does sound good. I like the idea of scripting the nodes. I'll give that a crack also.

PS: You could also set up VS Code to do Mermaid. https://www.50-nuances-octets.fr/en/posts/turn-android-tablet-into-ide-with-vscode-nix/ I got it to run. :)
