Customer Reviews

Great, except it's following me

Nifty little app, quite a smart way of checking without anyone else being able to see the actual balance

I don't understand why it wants my location though - even when not in use. I'm not very cool with that.

Five star app if it wasn't so big brother-ish


Good for checking the balance of one account. There is no way to quickly access the balance for multiple accounts, therefor, quite useless unless you only have one account.

The update has added a panel so Westpac can display annoying ads. The app is meant for checking balances, not for advertising!

Unable to transfer

App has allways been great up until iPhone did there latest update now I am unable to transfer any money via the app can only see the balance. Huge disappointment as I allways do my banking bill payments etc via this app
