Especially for World Savings Day ists a nice idea to make the app free of charge. With me it runs completely smoothly, as it did the "normal" Sparkassenapp which is always free. Would I download again, since the app my other bank not against it arrives - with a legitimation ID all accounts are visible, you have a password, as well as the Internet-PIN - am very satisfied. My Cro Sparkasse gave me very helpful!
