PuttrLab vs Numbers.golf

PuttrLab turns your iPhone into a precision putting analysis tool. Using tracking technology and your phone's slow motion camera, PuttrLab captures and analyzes every detail of your putting stroke. No expensive sensors, no studio time, no subscription. Set up your phone on a tripod above your putting surface, attach a free printable tracker to your putter, and get instant feedback on your stroke. FREE TO DOWNLOAD AND USE Start putting and tracking right away. The free version includes: - Tempo: The ratio of your backswing duration to your forward swing. A consistent tempo is one of the hallmarks of great putters. Tour professionals typically putt with a 2:1 tempo. - Face Angle: The angle of your putter face at the moment of impact, measured in degrees. Even small deviations from square can send your ball off line. - Instant stroke replay so you can see exactly what your putter did - Your three most recent sessions saved automatically UPGRADE TO PUTTRLAB PRO A one-time purchase unlocks the full PuttrLab experience. No subscription, pay once, own forever: - Acceleration: Whether your putter head is accelerating or decelerating through impact. Decelerating into the ball is one of the most common putting faults. - Stroke Path Symmetry: A symmetry rating of your backswing path to your forward swing path. A lower symmetry rating indicates your backswing and forward swing motion are more symmetrical, leading to more consistent putts. - Face Contact Point: The location on the putter face where the ball is being struck. Striking the ball towards the toe or heel of the putter can send putts offline. - Personalized coaching tips and drill recommendations after every session, based on your specific stroke - Unlimited session history with visual performance charts to track your trends over days, weeks, and months - Full session configuration — number of putts, time between putts, recording duration - Session tagging to compare putters, drills, or practice conditions - Made/missed tracking to correlate stroke metrics with results CORE FEATURES - 240fps slow-motion tracking for precise measurements - Support for both right-handed and left-handed golfers - Designed for use anywhere — practice green, home carpet, or hotel room HARDWARE REQUIRED All you need to get started is a tripod or phone mount that can point your iPhone toward the ground, and a printable tracking marker attached to your putter. Visit puttrlab.com for setup instructions, recommended tripods, and printable markers. Note: The tripod and tracking marker are not included. You have the option to print free trackers from within the app.
