A new update to the android app is being tested... by me!
People with accounts will now be able to use their API key + their username on the app.
With the additional information, you can be notified when a new block is found.
I'll post here after doing some more tests

Have you thought about providing the same app for the solo ckpool? Since there are no users, only btc addresses to mine to, it would work for everyone. I'd use it every day for the solo pool.
