Decent app – Baseline - Bitcoin Balance Tracker Review

But it seems to pull its price from blockchain.info. So when that site is down, good luck on getting a balance. Also, it would be nice if you could arrange your addresses in different ways. Notifications on addresses would make these guys unstoppable. If you get a debit notification from an account your monitoring while your phone is locked...amazing.
