Ratings and reviews

Great app, but the recent UI/UX change is a real head scratcher. In what world is tax the first button to pay on top instead of the bottom? The accounts screen is too big to fit a lot of accounts, and getting past the main screen takes you back to the old, better version of the app's UI/UX. Disappointed, unfortunately.

I was having issues with this recent update so went ahead and uninstalled the app. A few days later I decided to give it another go and reinstalled it again. Now it works just fine. After reinstalling I had to reconfigure login options (pin and fingerprint access), quick balances, notification settings, and any alerts I wanted. I logged out then logged in again and it asked me to select allow or deny for the app to access phone call log. UPDATE Broken again, app and website absolute shite :/ grr

Update: recent update to this app is somehow worse. It takes more screens to click through to make payments or transfer between your own accounts? In what world would I want my banking app to be any slower. Please take note of what BNZ/ANZ are doing with their banking apps, they have UX in mind. This app just feels clunky, outdated, and painful to use compared to almost any other banking app. It feels like it was made 10 years ago and is almost enough to make me want to swap banks
