Westpac one app is fantastic, however I recently purchased the iPhone X and initially I could use the Face Identification to login, now however it doesn’t seem possible. Personally I believe the developers need to bring this back to the app. As with touch I.D. The convenience was next to none. It’s like taking a step back to the Stone Age with not being able to login with either touch I.D. or face I.D. Yet I have apples latest & greatest device. Please look into this Westpac R & D team!!!

Apologies for the significant delay in this.
Face ID is now available on the latest version of Westpac One. Please update to the latest version, then enable it through settings in the ... (more) menu while logged out.

Good app, but...

I quite like this app. Rarely need to log into the full version to do stuff as you can do most of your things in app. I just wish the transfer funds between your own accounts feature could be more streamlined (with not having to press so many buttons & not have to confirm you want to make the transfer... why else would I be in that part of the app?) and the constant stream of adverts is annoying. But otherwise, a great user friendly app.

Still, after years not good enough.

Every day I see “Something went wrong” when I login. Restarting the app sometimes fixes the issues. Also transferring money between accounts takes too many clicks. Design improved and bottom area looks clean but top area under account is still yak. There are arrows, horizontal and vertical lines and 3 dots. This is nightmare from a design perspective! Also the rubber band effect is not implemented across the whole app! I also have the ASB app and they got it really clean and intuitive.

Thanks for the feedback.
