TeeTwin: AI Golf Coach
A swing coach built like you
Free · In‑App Purchases
TeeTwin pairs you with a real swing coach whose body is like yours, then your iPhone's camera compares every position and swing with theirs, live, with a score and the one thing to fix.
YOUR SWING TWIN
Calibrate once: stand in front of the camera for a few seconds. TeeTwin pairs you with a swing coach of your gender, playing hand and closest build. Every position you practise is their position on a body like yours, not a generic model.
STEP BY STEP, WITH INSTANT FEEDBACK
Get into each position of the swing (address, takeaway, top, impact, finish) one at a time. Your coach's skeleton is drawn over your picture and you see at once how close you are. Hold the position until it turns green and the next one comes up. The voice tells you what to adjust, so you can practise eyes off the screen.
SLOW MOTION, AT YOUR OWN PACE
Do the whole swing slowly, at your own pace. TeeTwin compares it with your coach's swing from address to finish and gives you a score, then the three things to work on first, position by position (P1 to P10): shoulder turn, hip turn, arm height and straightness, each with your angle, your coach's, and your two skeletons one over the other.
FULL SPEED, YOUR REAL SWING
Then swing at full speed. The iPhone in front of you films at 120 pictures a second and TeeTwin reads every position of your swing, P1 to P10, then gives you your score and your top three priorities, with a replay position by position. A second device at your side films the swing too.
A SECOND CAMERA FOR MORE PRECISION (OPTIONAL)
Got a second iPhone or iPad? Put it at your side with the same account: TeeTwin then measures your knee bend, torso tilt, and your shoulder and hip turn from the two cameras together. "Test my set-up" checks in a few seconds that everything is in place.
BUILD MUSCLE MEMORY
Short, regular sessions with precise feedback turn good positions into habits. Levels make each drill harder, and Progress shows your scores improving over time, drill by drill and position by position.
PRECISE 3D BODY TRACKING
TeeTwin tracks your body in 3D in real time. On iPhone Pro models, the back camera's LiDAR sensor measures depth for even more precise tracking. The camera picture never leaves your phone: TeeTwin only keeps your scores and seven body measurements.
A REAL INSTRUCTOR WHEN YOU WANT ONE
Book a live online lesson with an independent golf instructor, chosen by country, language and rating, at a time that suits you.
WARM-UP
Warm-up exercises counted and checked by the camera: hip and shoulder rotation, side stretches, to build the turn and flexibility your swing needs.
