I’m looking for a tool that has todo lists, as simple as it sounds, with some simple syncing support. WebDAV is more than enough. A widget on Android would be great, which makes it easy to see what I have to do during medium term. Once something is done, I check it on the list and it syncs.
I’ve experimented with multiple such tools and let me tell you something. There are downsides to using such tools that I’ve even went back to using pen and paper after having built my own.
Although NOT a direct solution per se, you might want to look into nocodb with a simple sqlite database, it has a kanban board and has API’s which you can use
Thanks for linking to the code. Make sure you run that code only in a secure environment, as it looks susceptible to XSS attacks. Not sure when it was written, but XSS attacks are something from 2 decades ago
