Swing health
Your top is better since your baseline. Shaft parallel is where your swing is furthest from good.
Why do I keep hitting it off the heel?
Rainge
It starts at shaft parallel. Your hips move toward the ball, so by impact you've stood up and your hands have nowhere to go but out. That's the heel. Your head holds steady, so it isn't that.
For your next bucket, one focus: hips stay back. Try the thought Right side crunch. Keep the forward bend as you turn through.
Chapter 1, Swing
“I have too many swing thoughts right now.”
Pick the club and one thought before the first ball.
Rainge cuts each swing into its own slow-motion clip.






Just what you need to see if it's working.

Every check is measured from your address lines: butt, hands and head.
It starts at shaft parallel: your hips move toward the ball, and by impact the strike is on the heel. Next bucket: hips stay back, with the thought Right side crunch.

Your setup stays behind you in blue.


The same line on both.
Chapter 3, Improve
“I had it last week. Where did it go?”
Where your swing is good, and where it’s furthest from good.
Your fix, set by set, until it’s on target.
Answers come from your own buckets, with one thought for the next.
Not a launch monitor, and not a replacement for your pro. A range companion that helps you practice with intent.
A range companion for iPhone. Prop your phone behind you and hit: Rainge checks every swing, gives you one thing to work on, and tells you after every set whether it’s working.
The ones that matter most: address, the takeaway, the top, shaft parallel, impact and the finish. Underneath, it reads all ten positions coaches use, so it can say where a fault starts.
An iPhone and something to prop it on, like a small phone tripod. Film from behind, down the line, with the whole swing in frame. Swings you’ve already filmed work too.
Only you. Rainge reads your swings on your iPhone. The coach gets your numbers, never video, unless you let it see up to five stills of your swings. Nothing else leaves your phone unless you share it.
No. It’s built for golfers coaching themselves. If you have a pro, show them the reads.
No. One focus and one thought at a time, in plain words.
Yes: open ranges in daylight and covered bays at night. When a video can’t be read, it tells you why.
Down the line for now. Face-on videos are kept but not graded.
Free during the beta. After that, a free version that does the job, and a paid one with extras.
Rainge is in a small TestFlight beta for iPhone. Leave your email and we'll send you a link when there's room, and the occasional update after that.
The Range Ball
It begins with a sound. A token drops, a machine shudders, and a wire bucket fills with a rattle you will hear for the rest of your life.
Somewhere in that bucket is the first golf ball you ever hit. You don't remember it, and it doesn't remember you. It went sideways, most likely. It may have barely left the ground. But something in you rose with it, and you came back.
It carries no name. Only three stripes, worn thin by ten thousand strangers: the beginner with a borrowed seven-iron, the regular two bays down, the player who will one day stand on a tee in April while the whole world holds its breath. It has been topped, shanked, thinned and skulled. It has been cursed at in every language the game is played in. And every so often it has been struck so purely that the bay next door went quiet. Each evening the caged cart gathers it from the grass. Each morning it is back in the bucket.
It will never be marked on a green. It will never fall into a cup. It will never make a birdie.
And yet every birdie ever made was made here first, on this ball, in the hours no one films. Quietly. A bucket at a time.
We named Rainge after it, and we built it to be what that ball has always been: in every golfer's story, and in no one's highlight reel. Easy to overlook. Impossible to get better without.
Make every bucket count.
