The best players share one thing: consistent tempo. OnTempo helps you find yours, measure it, and lock it in.
Upload any swing video — driver, iron, wedge, putt. Our AI pinpoints your takeaway, top of backswing, and impact, then returns your exact ratio. No signup. No download. No credit card.
Don't have a swing video? Film one at the range — face-on, full body in frame.
Tour Tempo shipped in 2004. Tempo Caddie in 2012. They're metronomes with golf skins. OnTempo is built for what your iPhone and Apple Watch can actually do in 2026 — measure the swing on your wrist, pulse haptic cues through the backswing, sync every session to iCloud.
Feel the rhythm through your wrist — no audio required. Pulses cue the backswing, transition, and impact without ever looking at a screen.
Your Watch's accelerometer reads every swing in real time. No camera. No launch monitor. Swing freely, get the ratio.
Every session is saved to iCloud. Start on the Watch, review on your iPhone. No accounts. No exports. It just works.
Once you know your tempo, the rest is reps. OnTempo gives you the three tools elite players use — on the device already in your pocket.
Three distinct tones guide your backswing, downswing, and impact. Feel the rhythm, internalize it, take it to the course.
Your Apple Watch detects each swing and returns your actual tempo ratio in real time. A crowd cheer confirms on-target swings.
Every session is recorded. See your tempo trends over 7, 30, and 90 days and confirm you're actually improving.
Three tones cue each phase of your swing: start the backswing, begin the downswing, and impact. When your Apple Watch is paired, haptic pulses sync with every tone.
Swing freely and your Apple Watch does the rest. The accelerometer detects each swing, measures your actual tempo ratio, and tells you instantly whether you're on target. A crowd cheer confirms great swings — no screen-checking needed.
OnTempo uses your Apple Watch's built-in accelerometer to detect swing phases in real time. No external sensors, no camera, no launch monitor — just the watch on your wrist.
Upload a swing to see your ratio, or download the app and fix it for good. Three days free. If it doesn't move the needle, we'll refund you or send a sleeve of balls — your pick.
