See your shot. Know your game.
Set your line.
Where you stand, the arrow you hit, where it breaks. Move any of them and ShotLab redraws your whole shot down a real lane, feet to pocket. Set it once and it holds frame to frame.
Then just bowl.
Strike, spare or pins left. One tap and the frame is in. Then one quick question: did you hit your mark? Your line stays on the lane and ShotLab keeps score.
Every leave gets a line.
Leave the 10 and ShotLab draws the spare line for it. Pick up your spare ball, go straight across the lane. Save it for that leave and it's your line next time.
Ask your coach.
Ask about a leave that keeps beating you, your last game or your next ball. Coach reads what you bowled and answers with your own numbers, then gives you one thing to try next time.
Opening to Founding Bowlers first.

Built by a bowler, for bowlers.
Hey, I'm Robby. I started bowling a few years ago and fell in love with the game, so much that I built an app to help me get better. I'm still figuring out my own game, and I want ShotLab to help you with yours. It's in beta, so what you tell me shapes what comes next. Try it, then tell me what would make it better.
