I migrated from Notion to Obsidian, for the sweet, sweet, open standards feeling.
For backup, it syncs (2-way) to GitHub. I didn’t want to set it up to also sync with my phone, and didn’t necessarily want the notes on my phone, but I did want to capture ideas while I was out and about.
So, I created an Android app that would do that, and only that. It takes text, and sends it directly to your GitHub repository. If you’re offline, it will queue them on your device, and send them later.
I’m in the process of publishing it, and need some testers.
