Your swing already has a tempo.
Find it. Then keep it.

Three tones, and one thing to think about instead of ten. Take the club back on the first, reach the top on the second, strike the ball on the third.

Three tones, one thought

Most swing advice gives you a checklist to run through in two seconds. This gives you a rhythm to match instead — your body sorts out the rest better than your conscious mind can.

1

Take it back

The first tone starts your backswing. Nothing to think about before it.

2

Top of the swing

The second tone is where the club changes direction and the downswing begins.

3

Impact

The third tone is the ball. It's pitched higher and accented so you can't miss it.

The ratio behind it

Analyse enough tour swings frame by frame and a pattern shows up: the backswing takes roughly three times as long as the downswing. Around the green that shifts to about two to one. Tempo Town gives you five settings for each, so you can find the speed that suits you and train the proportion that doesn't change.

Measure your own tempo

Guessing at your rhythm isn't much use. Film your swing on your phone, load it in, and step through frame by frame — mark the takeaway, the top and impact, and Tempo Town works out the rest.

Put it on your home screen

It's a website, so there's no app store and no install. But it behaves like an app if you want it to.

iPhone

Open in Safari → Share → Add to Home Screen. It launches full-screen with no browser bars.

Android

Open in Chrome → menu → Add to Home screen. Same result.

One thing to check

Take your phone off silent. The tones come through the media channel and the silent switch will mute them.

Questions

Is it really free?

Yes. The trainer and the frame counter are both free, with no account and no ads.

Do I need slow-motion video to measure my swing?

No, but it helps. A normal 30fps clip gives you about a frame of precision either side, which is enough to see your ratio clearly. Slo-mo gives you a much finer read on the exact moment of impact. Either way the app works out what it's looking at.

Which tempo should I use?

Measure your swing first — the app will point you at the closest setting. As a rule, start near your own natural speed rather than the fastest one. The ratio matters far more than the raw speed.

Does it work without a signal?

Once the page has loaded it runs entirely on your phone, so a patchy connection at the range isn't a problem. Adding it to your home screen makes that more reliable.

Do my videos get uploaded anywhere?

No. Videos are read directly by your browser and never leave your device. There's no server to send them to.
