My first impressions

You are focusing on the right things

Cloud backup+ privacy+ user friendly UI + ease of transfer+ FOSS

The app still need a lot of things

1. Settings menu feels really old
2. As someone who is used to .md i cant bring my valut from obsidian which is a big con
3. An option to choose where to type as defualt ( title or context)
4. E2EE
5. Support for high refresh rate or better animations to make it feel super smooth

Im not sure if you used ai to make this app or not but i would guess that its easier to make a decent app by using a fork of an existing app and improve it
