For a mobile/online only bank, the Zenbanx app is appallingly bad. It is slow and very unresponsive to user interactions. Buttons take multiple touches to work. The damn blurring transition between each screen takes forever. Overall, it is the worst banking app Ive had the displeasure of using. Its really too bad, as I rather like the idea of this bank with its easy multi-currency holdings.
