Tenpin Doctors is a ball motion simulator, layout planner and AI coach in one app — built for bowlers and pro shop operators who want to know what a ball will do before they drill it or throw it. SEE THE BALL BEFORE YOU THROW IT Roll any ball on a simulated lane with your own numbers: rev rate, axis rotation, tilt, speed, surface and loft. Set your lay-down board and your target at the arrows and watch the line. Change the pattern, change the surface, move your feet — and see what it costs you. ASK THE TENPIN DOCTOR An AI coach that knows your specs, your PAP and the ball you’re holding. Ask for a line to the pocket and he’ll work one out and set the sliders himself. Ask why a ball rolls out, what to change on a burnt-up house shot, or how a layout will react — and get an answer, not a search result. 2,700+ BALLS, KEPT CURRENT Real RG, differential and core data, updated from our server as manufacturers release them. New releases arrive with their specs and a traced 3D core, ready to roll on the simulator with your layout and release. PLAN LAYOUTS THAT MAKE SENSE Dual angle and VLS layouts worked from your own PAP, with the pin, PSA and mass bias placed on a 3D ball you can turn. Save them, compare them, and simulate the result before a single hole is drilled. FIND YOUR PAP AND YOUR SPECS Scan your ball, find your grip centre and measure your positive axis point. Calculators for axis tilt, rev rate, ball speed, span and pitch. TRAINING AND KNOWLEDGE Drills, practice programs and a reference library covering lane play, ball motion and layout theory, with new content added through the season. FOR COACHES AND PRO SHOPS Keep every bowler’s specs, layouts and saved shots in one place, synced to every device you work from. LIVE TRACKING — OPTIONAL ADD-ON Tenpin Doctors Trackers and Duos are separate hardware accessories, sold separately, that track your ball live on the lane — speed, boards and shot-by-shot data straight into the app. The app is fully usable without them; they add live tracking for bowlers who want it. PINPOINT PRO $9.99 per month or $69.99 per year.
