I glad you enjoy it. Given that I'm working on this alone, I won't have the resources to make a native app soon. That said, I'm working on the mobile webapp right now and will try to implement service workers so you can get notifications and have offline access.

Install to home screen removes the browser UI, so it won't be native, but it'll be close.

Hopefully iOS will support service workers in the future.
