The Powerball Assistant is a fun way for those that play the lottery to choose the numbers for their tickets. It gives them the charts of numbers and information all in an app for the iPhone.
There is a screen that shows recent drawings, and another that will show the top numbers using three different number probability systems (Binomial, Geometric and a Proprietary system).
There are sections to show how long it has been since numbers have been picked and how many times that they have been picked. There are charts of numbers and the important hot and cold numbers.
Please note that the app is a tool to help you pick numbers and cannot pick the winning numbers for you, I wish that it could. Please play responsibly and only spend what you can afford.
