Scrabble Vision: Scorekeeper is a fun and fast way to score and manage Scrabble games. If you don’t know how to play or score, it’s never been easier.
All you have to do is set up your physical Scrabble board, pick your letter tiles, snap a picture of the physical gameboard, and you can start playing – the app will keep tabs on the points.
You can also see how many points you have left to score. The app features auto-scoring, as well as word hints, countdown timers, a digital dictionary, and a worldwide leaderboard.
The app is also able to find playable words for you.
