The app is really convenient for tracking income and expenses for any category you can dream up. One thing I really like, besides the fun animation of the numbers as money is spent or added, is the fact that after the user inputs a transaction in one of the categories, the app kicks you back out to the main view of all of your categories. Everything seems well thought out. Many expense/income apps first have terrible design and second dont understand the user is inputting transactions in on the go. This app succeeds in both categories. It is quick! No bloatware here. Straight and to the point with this app and it is pretty beautiful and utilizes green and red colors without me thinking of Christmas :)
For me, all the app needs is the option for the user to set decimals or not and iCloud backup. I have been in touch with the developer and it sounds like these items could be in the works. He is very responsive and helpful with any questions.
