There's nothing to install. Just sign in, set up a match, give your players the match ID, and everyone meets there. Players ring-in by touching a ring-in button on their phone or tablet device:
During a match, each team can have up to 5 players each, but team rosters can have up to 15 players who can be subbed in and out easily. And there's no limit to the number of team rosters you can create, save, and re-use. You can even import rosters from opposing coaches.
On a toss-up (if you're playing standard quiz bowl rules), QuizBowl PRO offers you easy-to-read buttons for Power, Right, Wrong, and Neg:
Click on these buttons, and your scoreboard is adjusted automatically. What could be easier?
An individual hosting subscription allows you to create and host an unlimited number of matches and maintain an unlimited number of team rosters for $15/month or $99/year. Group subscriptions for leagues or districts are also available for 5 or more teams and can be paid for via a purchase order.
QuizBowl PRO's default options are set to play according to standard quiz bowl rules, but you can modify these settings to fit your needs. Don't use Powers and Negs? Just turn them off. Everything is customizable.
QuizBowl PRO also supports bonus questions - with or without rebounding/bounceback of missed parts - as well as team questions.
