R00BT Line

Settle close calls in pétanque, bocce, cornhole and croquet with an AR ruler, live scoreboard, match history and offline dispute snapshots.

R00BT Line is an app for fair judging in amateur precision games: pétanque, bocce, cornhole, croquet, and custom local rule formats.

Turn your iPhone into a pocket referee for backyards, clubs, bars, parks, and small tournaments. R00BT Line helps you create matches, manage teams, track scores, control rounds, follow turn order, and resolve close calls without arguments.

The main feature is the Camera / AR ruler. Open the camera, mark the target and the object, and the app helps measure the distance in centimeters.

Use it to check whose boule is closer to the jack in pétanque, who is closer to the pallino in bocce, whether a cornhole bag stayed on the board, or to record disputed progress or penalties in croquet.
