I have here a Samsung SM-G310HN - because the app goes without problems. With this app I have my account on the move in control. You can retrieve account balances and all transactions, so what has been debited and, Also new transfers, you can enter it. (Did I not tested, because I do not go.) Enjoyed that the app is made very intuitive and I without a manual to read immediately knew how what works. For me doing the app everything I want and that's why there are 5 star :-)
