In the past week of my experience with bitcoin i saw a lot of apps that are giving satoshis with a "game-system" but never found a "faucet-app" and Claim Bitcoin is exactly that: a normal faucet but for android.
The app is pretty clean and after each claim you will see the usual ads that you see in other apps too.
Rates are not bad at all and you can get 500 satoshi every 30 minutes.
Payments on sunday after 10.000 satoshi. I didn't get any payment yet but it's just the first week of the app and there is a payment proof on the owner's blog that you can check HERE.
You can download the app from the playstore:
