StrikeKeeper: Bowling Scores

StrikeKeeper is a bowling score keeper and stats tracker for your own bowling — free, with no ads, no subscription and no paywall. Every feature below is free.

Mark the pins that fell
Enter each roll on a pin diagram, or just tap the number when you're in a hurry. The diagram is what unlocks split and pin-leave stats, and you can switch between the two in the middle of a frame. The Score tab shows the highest score you can still reach.

A scorecard that keeps up
Frame-by-frame scoring in proper bowling notation, updating as you throw. Strikes, spares and the tenth frame all handled. Entered one wrong? Tap the frame and fix it.

See which spares you miss
Split conversion (counted the USBC way), single-pin spares, 10-pin and 7-pin conversion, and the leaves you see most, each drawn as a little pin rack with your make rate. Plus the number that hurts: what your average would be if you'd made every single-pin spare.

Your league night
Tag games League, Practice, Tournament or Open bowling, and see your league average on its own. Set your league's basis and percentage and StrikeKeeper works out your handicap. See how you bowl game 1, 2 and 3 of a night.

Ball, lanes and oil
Note the ball, lane pair and oil pattern for each game, and see your average and strike rate with each ball.

Bring your old games
Type in past scores, or import a spreadsheet — StrikeKeeper's own export, another app's, or your own (a Date and a Score column is enough).

Bowl with friends
Add friends with a friend code, and once you've both added each other, see each other's averages and recent games — and watch a friend's game live while they bowl. Sharing is off until you turn it on, and nobody can find you without your code.

Personal bests
High game, high series, longest strike run, clean games, your first 200 — and a call-out on the spot when you beat one.

Family night
Score up to six bowlers on one phone. Everyone gets their own game, and theirs never touch your average.

Share and export
Send a picture of your scorecard to the group chat, or export every game to a spreadsheet.

Works with no signal
StrikeKeeper saves every roll on your phone first — including the game you're bowling — and keeps the screen on while you bowl. Dark mode follows your phone's setting.

An account is optional
Everything works without signing in. An account adds a backup, so your history follows you to a new phone, and friends if you want them. You can delete it, and everything on our server with it, from inside the app.

No ads, and no tracking. StrikeKeeper counts a few anonymous things — how many games get finished, and when the app hits an error — so we know it works. Nothing in those counts is tied to you, and there is a switch on the Stats tab to turn them off.

Built for tenpin league bowlers and open bowlers alike.
