Tornu Golf - Swing Tempo
Measured Rhythm & Timing
Free · In‑App Purchases
Your first 50 saved swings are free. Measure backswing and downswing to the millisecond on your wrist, and see whether you can repeat it — the only thing that matters.
Tornu measures your golf swing tempo on your Apple Watch and tells you the truth about it.
Backswing duration. Downswing duration. The ratio between them. And — the part that actually improves your golf — how much all of that varies from swing to swing.
MOST APPS GUESS. THIS ONE MEASURES.
A metronome tells you what tempo to copy. Tornu tells you what yours is, to the millisecond, from the motion of your own wrist. No ball required, no net required, no camera required. Swing in the garage in January and it works exactly the same.
WHAT YOU SEE AFTER EVERY SWING
• Backswing and downswing, in seconds
• Your tempo ratio
• Crest — where in the downswing your hands gained speed fastest
• An arc on your watch that replays your downswing at its real pace
WHAT YOU SEE AFTER A SESSION
• Every number with a ± beside it, per club
• Green when your spread is inside your target, red when it isn't
• Your history, and whether the spread is narrowing
• Every individual swing, kept, so a bad one can be deleted rather than skewing the average
CONSISTENCY IS THE PRODUCT
Anyone can hit one good swing. Tornu is built around the second one, and the fifth. The ± beside every number is the whole point: it says whether that number is really yours or whether you got lucky once. Set the tolerance to Relaxed while you find a baseline, then tighten it as you improve.
OPTIONAL CAMERA, TO SEE IT
Prop your iPhone up and Tornu records every swing your watch reads. Replay it with Crest (where your hands gained speed fastest), Axis (did you sway?) or Tilt (shoulders, hips and spine). Videos are saved on your iPhone, and your watch can open and control them. The camera doesn't time anything — every number comes from the watch.
WHAT TORNU WILL NOT TELL YOU
No clubhead speed. No ball speed. No club path. No face angle.
The watch sits above the wrist joint and never sees the clubface, so those numbers cannot be measured from there — only estimated. Other wrist apps print them anyway. We would rather show you four numbers you can trust than eight you can't.
BUILT FOR THE RANGE
• Start on either device, finish on the other — everything mirrors
• Your bag, with the clubs you actually carry
• The screen stays awake while you're swinging
• Works with a weighted trainer, indoors, all winter
YOUR DATA STAYS YOURS
No account. No login. Your swing measurements never leave your iPhone and Apple Watch — no timing, no tempo, no crest, no sessions. Swing videos are saved on your iPhone only. Back it up to a file you keep, or delete everything in two taps.
FREE TO TRY
Your first 50 saved swings are free, with every feature unlocked. No credit card and no clock — take them over a month if you like. After that, Tornu Pro is a monthly or annual subscription, or a single one-time purchase if you would rather not subscribe.
Requires an Apple Watch. iPhone required for setup, review and video.

Swing video, properly. Every swing gets Crest, Axis and Tilt overlays, saved right on your iPhone. Open any swing full screen to jump straight to TOP and IMPACT, step through it frame by frame, and run it all from your Apple Watch. Plus a refreshed watch screen and a simpler Settings.
