Lottery Pools APP
If you answered yes to any of the above questions, Lottery Pools app for Android is your solution! Here, one person buys the tickets (pool leader) and inputs them into the app and adds all the other participants to the pool. No one can remove a pool or a ticket from the pool once they are created, and every one in the pool can see them and know which tickets have won. (With read-only access.) This way, every participant can know exactly if they've won anything and how much every one should receive.
