Ratings and reviews

I have had no problems what so ever with this app. regardless what devices of mine iv used it on. it gives me peace of mind and when (its happened alot) iv forgotten my password, iv found it easy to reset it. since iv activated finger, things are alot more easier. Thanks westpac, everything i need done is all in this app. If there are adds in the app, iv never noticed them. They dont seem to affect my use of the app in any way.

Worst banking app I've ever used. Opened account yesterday, app worked fine for a day. This evening, app won't let me in "Something went wrong" error repeatedly. Can log in fine via the website. Pretty pisspoor experience of banking with Westpac already, this does not instill much confidence in their online presence or security (which was already not convincing during the requirement to ring them, the telephone handler sounded like a scammer)

I've tried logging in and for so unknown reason it won't let me this is the second time it's done this in a month, but I can login in on another phone. I've uninstalled and reinstalled installed and it worked fine now again it won't let me in, I've checked everything it's all updated. What is going on?
