ModernKeePass is port of the classic Windows application KeePass 2.x for the Windows Store.
It does not aim to be feature perfect, but aims at being simple to use and user-friendly.

Contribute

I'm not the best at creating nice assets, so if anyone would like to contribute some nice icons, it would be awesome :) Otherwise, there are still many things left to implement:

Entry custom fields
Multi entry selection (for delete, or move)
Move entries from a group to another
Create key files
Open database from URL (and maybe some clouds?)
