LaneCaddie
The bowling app your Apple Watch was made for.
Free to score. $7.99/mo to detect every shot automatically — then see the motion behind it. Built by a left-handed league bowler.
Built by a real league bowler in Colorado — and tested lefty-first.
Wear it. Bowl. Improve.
Your Watch catches every shot the moment you release — you just tap what fell. No phone on the lane.
Wear your Watch
On your bowling hand. Start a session from the LaneCaddie complication. No calibration, no setup.
Bowl normally
Every shot is detected automatically the moment you release, and its motion is captured.
Tap what fell
One tap for a strike or spare, a couple for a leave. The Watch keeps your running score.
See the motion
Per-shot tempo, posting, and follow-through — and how they trend over every game and session.
A scorekeeper that actually understands your shot.
Wrist-IMU shot detection — a first in bowling
The moment you release, your Watch knows you bowled and captures the motion of the shot — your tempo, your posting, your follow-through. Then you tap what fell. No buttons to start a shot, no phone on the approach.
Powered by CoreMotion + on-device machine learning. Nothing leaves your wrist.
See the motion behind every shot
After each ball, LaneCaddie shows your tempo, posting stillness, and follow-through — not as raw numbers, but as how this shot compares to your normal, with at-a-glance consistency dots. Stay green and you're repeating; drift yellow or red and you'll know before it costs you a frame.
Rev rate and axis rotation are coming in a later update.
Multi-game sessions, wrist-side
Keep full, USBC-style scoring for a whole night of league play right on the Watch — multiple games, every frame, no phone required. Your iPhone stays in your bag.
Your game, trending
Average score, strike rate, spare conversion — all in one dashboard on your iPhone. And the more you bowl, the smarter it gets: over a season of data, LaneCaddie starts to surface what your best games have in common.
Motion-correlation insights build as your history grows.
Camera analytics — and fully automatic scoring
Point your iPhone down the lane and LaneCaddie measures ball speed, entry angle, and breakpoint board — and fills in your pin count automatically. The kind of data that used to require a $25,000 lane-side camera rig.
Start free. Pay only for what you want.

"I'm Jacob — a left-handed league bowler in Colorado. Every bowling app I tried made me tap my score in after each frame. The whole point of the Apple Watch is that it should know what you just did. So I built the one that does."
