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.

At it's core it provides a basic budget tracker but there's some tweaking needed. I should be able to edit the timeline for what's typical, let me select however many months is relevant. There should be an easier way to change categories for the same transactions and also create custom categories. Also once you've changed the transaction category, the menu should drop down so you're back to the transaction lists. The daily summary is honestly useless, maybe a week or a fortnight at least.

Current version is not good compared to previous version. 1. Spending notifications come through about 3-5 days after the transaction. So it looks like someone is using the account. 2. Interface is hard to use now. Tap a categorie and the information completely changes and it's hard to go back. 3. Modern look interface is ugly compared to previous version. Makes it hard to read at times.
