The golf performance app
Every round starts somewhere.
Every golfer belongs somewhere.
Welcome to Scratch Circle.
Free to start. Three swing reviews a month on the Par plan.
The loop
Most golf apps tell you what happened.
Scratch Circle tells you what to fix, then watches you fix it.
-
Film it with the phone you have
Record in the app on iPhone at your phone’s fastest frame rate, or upload any swing video. No sensors, no hardware.
-
Get one clear thing to fix
Six checkpoints, what the app found and why it matters, then Your Focus. Tempo is measured from your hands and shown only when it can be confirmed.
-
Drill it, then film again
Your Focus becomes a 2-week plan with the drill that matches it, from a library of 117. Check it with five balls on the Launch Monitor or a new film, and put the old swing and the new one side by side.
-
Honest about what it can’t see
If the angle, the light or the clip makes something hard to judge, the app says so instead of guessing.

Show off the work.
Add your photo, pick a club, and the app builds a collectible card from your own launch monitor shots and swing analysis: ball speed, carry, consistency, form and how far you have come. Ratings compare each stat with typical players for the club, so a beginner and a low handicap can both earn a good one.

Your next swing is the best place to start.
