Stop guessing about your game. PinPoint pairs with the PinPoint Duo trackers to measure your shots in real time — and turns your iPhone into a pro-shop measuring tool for your equipment. RUN THE PINPOINT DUO TRACKERS Set the PinPoint Duo sensors down the lane and connect over Bluetooth — up to six devices at once. As you throw, PinPoint reads your ball speed and the exact board your ball is crossing at each point down the lane (7 ft, 15 ft and 40 ft), shot after shot. Track a single lane or run two lanes at once in Duo mode, with a live scoreboard you can flip sideways on a tablet. BUILD CUSTOM PRACTICE SESSIONS Design a shot-by-shot practice routine — set the target board you want at every sensor and how many shots to throw at it — then run it against the trackers and save your results for every device. See exactly how close you're hitting your target and how your speed and line hold up under repetition. Structured training programs help you build a plan and come back to it week after week. FIND YOUR PAP FROM A PHOTO Throw a shot, then take one picture of your ball with the oil ring, pin, CG and mass bias showing. Fit the circle, drop a few markers on your finger holes and the oil ring, and PinPoint calculates your Positive Axis Point — your PAP — automatically. No tape measure, no guesswork, no waiting for the pro shop. GET YOUR FULL LAYOUT Once it has your PAP, PinPoint works out your layout numbers so you can record exactly how every ball in your bag is drilled. Measurements round cleanly to the nearest 1/16" and layout angles to the nearest degree — the way a driller actually writes them down. BUILD YOUR ARSENAL Save every ball you own with its specs, layout and your own notes. Switch between bowlers so the whole family or team can keep their gear straight in one place. Rename, re-scan and organize your bag however you like. SEE YOUR BALL MOTION The built-in 3D lane simulator draws a real lane — every board, arrow and dot — and rolls your ball down it. Pick your laydown and breakpoint, and watch how the shot shapes based on real inputs instead of hitting the pocket every single time. It's a fast way to picture what a change to your line or your equipment really does. BUILT BY BOWLERS, FOR BOWLERS PinPoint comes from TenPin Doctors. It's made for league bowlers, coaches, pro-shop operators and anyone who wants to understand their equipment instead of just throwing it. COMING SOON Find My RPM & Tilt — read your rev rate and axis tilt straight from a slow-motion clip of your release — is in the works and arriving in a future update.
