### 1/5 — Terrible app

*2026-08-19, version 43.1.2*

Never log ins, its a horrible app and unreliable when needed most

### 2/5 — Login

*2026-08-19, version 43.1.2*

Why does it say my passwor dis not correct when i literally have it saved everytime? This is the third time its happened and im sick of ringing up and asking them to reset my password. Do better westpac your app sucks

### 1/5 — So many times I can't log in over the years

*2026-08-19, version 43.1.2*

Have been with Westpac for 6 years (too lazy to move) and not being to log into their app is common issue. I get the circle of doom and try again later. Considering they are a bank with money it seems like this is a basic they would have sorted by now, yet it has been ongoing. It's not my phone, have a newer model, and I update the app in the hopes it will get better. But my hopes are yet to be realised.

### 3/5 — Ok I guess

*2026-08-14, version 43.1*

Seems ok but a bit average for a big bank. Has a few glitches like when I try to view details of a Term Deposit I get an error message saying I can’t open a new TD. Meh..

### 5/5 — Getting better all the time

*2026-08-05, version 43.1*

I love the new features in Westpac one - especially the card controls.

### 1/5 — Identity fraud risk

*2026-07-31, version 43.1*

Collects biometric data without consent. This data could be stolen and used for identity fraud.

### 1/5 — Forced behaviour tracking

*2026-07-31, version 43.1*

This app tracks tour behavioural biometrics without permission. Do not use.

### 1/5 — App crashes a lot

*2026-07-05, version 42.4*

The app crashes a lot with me having to login with Safari a many times. Now have a feature you order accounts and when you try and save that new order the app just crashes. This is the poorest app compared to the other banks

### 2/5 — Hopeless for such a wealthy company

*2026-05-20, version 42.2.2*

For the most part of the app is okay and does its job but there are two things which perpetually annoying and seem never to be fixed. The first one is when you go to search for a transaction amount instead of getting figures you get a selection of grey lined boxes. Contacted support about three months ago about this still not fixed l. Second thing when I went to file a suggestion to fix this, the Send function broke with a generic error message. The app will never get better if you can never hear from us.

### 2/5 — 🙄

*2026-05-13, version 42.2*

Now the card feature just leads then freezes!!
