I've had the privilege of using the app through the beta cycle, and it's found its way to my home screen. That rarely happens with a new app. I was on a look-out for a budget tracker that felt like it belonged on the iPhone, and one that was private. Many budget trackers ask you to link your bank account, which is not a great idea.
The app is great if you're looking for a quick way to log your expenses daily. The categories and budget tools have really helped me monitor and limit my spending over the last couple of weeks. And what more do you want from a budget tracker!
