Really easy to use, and pretty good. No ads but you do need to be a westpac customer. It attempts to categorise expenses and its usually like 70% accurate. The other thing is it will sometimes count a pending transaction twice for some reason (it's a very minor bug but it'll probably be fixed in the next update). Overall good app though, like you can set it up so it gives you a notification every time money leaves your account and set targets/budgets etc.

Interesting to see the breakdown. Note: Sometimes have to re-enable the app via the app store to then open it and then agree to T&C's/policies. Would be nice if there was a tour to show how to get the most out of the app.

UPDATE: uninstalled, reinstalled, restarted phone (android 13), and now it won't even go past the intro slide screens, will not open at all. completely useless. Please provide a fix asap!!!! Had this app for ages...was great. Now it sends constant repeat notifications. For example; I purchased my groceries yesterday, and since then, I have had 5 notifications yesterday about it and 2 this morning. It's becoming annoying 😒 not helpful.
