Throwl

A free darts scoring app for keeping track of games with friends and seeing how everyone played.

What is Throwl?

Throwl keeps score while you play darts, whether the players are friends with Throwl accounts or guests sharing the same device. Play a standard x01 game or practice every double in sequence, then review the result and detailed stats when the game is over.

Your account keeps a private history of your games. Finished matches can be revisited for their results, while an unfinished game can be picked up where it left off.

Features

• Play x01 from 301, 501, or a custom starting score, with a double checkout.

• Score games for up to eight account holders or local guest players and randomize the playing order.
• Add friends by email and invite them into games.
• Record throws on an interactive dartboard and keep a live scoreboard.
• Reopen finished games for results, progress charts, and throw and turn stats.
• Resume unfinished games from the saved game history.
