Is it just that there’s no Linux one but there is mobile?
Maybe with Kotlin Multiplatform someone will get an existing mobile one running on Linux as that would be useful.
I can’t imagine it’d be too hard given a todo app doesn’t need a lot of Android specific functionality. I’m in the middle of converting my app to target desktop/ios/android and its been going very well and the tooling is improving rapidly.
That or someone might write a nice one as a starter project as Multiplatform from the start to learn it?
