Contrary to popular belief, the mobile app is not forgotten - I count about 40 releases in total for the past 12 months.
We probably spend as much time working on it than on the desktop one, but unfortunately it is much harder to develop for mobile, especially when you have to make sure it works on the many different Android devices and iOS versions, plus the extra work to comply with the ever changing requirements from the Google and Apple stores. Many of these changes are not visible to the user, but without this boring never ending maintenance work the app simply wouldn't exist.
We do plan to update the UI/UX of the mobile app though, as we're aware it could be made more intuitive. I'm very keen on improving this and hopefully it will happen this year.
It’s a pretty clunky experience trying to creating and editing notes. There’s also the constant worry about conflicts, to try and cut them down I open the mobile app, hit sync, make an edit then hit sync again. I use WebDAV, maybe Joplin Cloud is better at it
