Lottery Fever for Android phones
This is a tool that lets you pick from one of three different games, or make a custom game of your choice, where you pick the ranges, price per ticket, number of tickets per game, whether there's a bonus number, how often you want to play, how long, and more. You also choose your lucky numbers or have numbers randomly generated. You select payouts, whether multipliers or set numbers such as jackpots.
You then run the numbers and it calculates a set of statistics for you, including the win-lose ratio, win percentage, last date you bought a ticket, date of jackpot (if you play "until jackpot"), number of hits per each number combination and amount of wins, frequency of numbers selected, etc.
