ThreeOne: Golf Tempo Trainer and Golf Metronome for iPhone
One swing thought instead of ten: your golf tempo.
ThreeOne is a golf tempo trainer for the range and the practice green. Swing to three tones at the ratio great ball strikers share, then measure your own backswing from a video and watch the calm of your best days become the rhythm you bring to every tee.
In final testing. The App Store link appears here the day it is live.
ThreeOneGolf tempo trainerA golf metronome that carries the club for you
Press play and let the sound do the counting. One tone starts the takeaway, one meets you at the top of the backswing, one lands on the ball. What great ball strikers share is a ratio, not a speed: 3 to 1 for the long game, 2 to 1 for the short game and putting, written the way golfers say it, like 24/8. The whole standard ladder is open from the first tap, so your golf tempo is always a moment away.
Putting tempo you can trust when the round is on the line
Short putts are lost to a hurried stroke more often than to a bad read. Run the 2 to 1 tones for putts, chips and pitches and feel the stroke take its time. Set the rest between sets to fixed, tap to start, or random, so you react to the tone instead of anticipating it.
Measure your own backswing and stop guessing
Pick a video of your golf swing from Photos and tap three frames: takeaway, top, impact. A result card shows your backswing and downswing as two bars of time beside the tour ratio, one coaching sentence, and the one tone preset that trains it. It is the swing trainer that tells you what to work on before the next bucket.
Watch your golf tempo settle, week by week
Every measurement joins your history: a ratio trend, a consistency read, and a streak that keeps your golf practice honest. Over the weeks the scatter tightens, and the calm of your best day starts showing up on the ordinary ones.
A swing metronome that fits the way you practice
Tones play over your own music and keep going with the screen off, which makes this the swing metronome you will actually bring to the range. Build custom ratios when your own swing pace asks for one, and pick the rest between sets that suits the session.
Your best swings came from one feeling, rhythm, and the rushed ones came from ten thoughts at once.
Three tones at the ratio you choose, and your own backswing to downswing ratio measured from a video.
What ThreeOne changes about your swing.
The swing thoughts go quiet and one rhythm takes their place.
The short putt on the last hole gets the same stroke as the practice green.
You stop wondering whether you rush it and read your own number instead.
The rhythm you found at the range is the one you take to the first tee.
Week by week the scatter tightens and your good days stop being rare.
Tomorrow at the range, one rhythm could replace ten swing thoughts.
For the golfer whose best round felt like rhythm.
What ThreeOne does
A golf tempo trainer and golf metronome: swing to three tones, then measure your own backswing from a video and watch your tempo settle.
Your best swings never came from ten swing thoughts. They came from one feeling: rhythm. ThreeOne is a golf tempo trainer that hands you that calm on demand, with three tones to swing to and a putting tempo you can trust when the round is on the line.
Looking for a golf metronome that does more than beep? ThreeOne plays the tones for the long game and the short game, then measures the tempo of your own golf swing from a video, so practice starts from your numbers instead of a guess.
A golf metronome set to tour ratios
Press play and let the sound carry the club. One tone starts the takeaway, one meets you at the top of the backswing, one lands on the ball. What great ball strikers share is a ratio, not a speed: 3 to 1 for the long game, 2 to 1 for the short game and putting, written the way golfers say it, like 24/8. The whole standard ladder is open to you from the first tap and stays that way, so your golf tempo is always a moment away. Tones play over your own music and keep going with the screen off, which makes this the swing metronome you will actually bring to the range.
Putting tempo for the ones that matter
Short putts are lost to a hurried stroke more often than to a bad read. Run the 2 to 1 tones for putts, chips and pitches and feel the stroke take its time. Set the rest between sets to fixed, tap to start, or random, so you react to the tone instead of anticipating it. This is golf training that quiets the mind instead of filling it.
Measure your own backswing
Stop guessing at your swing tempo. Pick a video of your golf swing from Photos and tap three frames: takeaway, top, impact. A result card shows your backswing and downswing as two bars of time beside the tour ratio, one coaching sentence, and the one tone preset that trains it.

Straight answers.
What ratio should I swing to?
Great ball strikers share a ratio rather than a speed: 3 to 1 for full swings, 2 to 1 for putts, chips and pitches. ThreeOne writes them the way golfers say them, like 24/8, and lets you build a custom ratio when your own swing asks for one.
How do I measure my own tempo?
Pick a video of your golf swing from Photos and tap three frames: takeaway, top and impact. ThreeOne times the backswing and the downswing and shows your ratio beside the tour ratio.
Do the tones play with the screen off?
Yes. The tones keep going with the screen locked and play over your own music, so the phone can stay in your pocket or your bag.
Does it help with putting?
Yes. Run the 2 to 1 tones for putts and chips, and set a random rest between sets so you react to the tone instead of anticipating it.
Do my swing videos leave my phone?
No. Everything runs on your iPhone and your videos never leave it.
Do I need an account?
No. There is nothing to sign up for. Open the app and press play.
Swing with one thought.
Press play at the range and let three tones carry the club.
