Next Round is a raffle app that can be used in events to raffle out prizes. You can create a raffle and email a link to your friends who have the app to join your raffle. You can also enter the names of your friends manually. If you have joined a raffle you can see the most recent winner, number of tickets you own and the total number of tickets in the raffle.
It can also be used to select a random result from a list of choices. For example: You have an extra ticket to a game but cannot decide which one of your friends to invite? Or having to decide where to go for lunch?
