Every rep counts. Now every rep teaches.
Repgroove watches you move the way a coach would, then tells you the one thing to fix next, and proves it's working.
You've put in thousands of reps. Almost nobody was watching.
One coach, eight players. A couple of minutes of real attention each, per hour.
For an hour of private coaching. Most players never book one.
Feedback on the reps in between, where a bad habit quietly gets grooved in.
One rep, coached.
Here it is on a tennis serve. The same engine works on any movement: it tracks you, measures what matters, picks the one thing to fix, and shows what changed. Every number in the film is what it measured.
One fault. One drill. No report card.
- The biggest thing first. Each session surfaces the single fault holding you back most, not twelve at once.
- A coach's words, not a chatbot's. Cues and drills come from your sport's pack, written by coaches. The AI only chooses among them.
- Stay on it until it's clean. You move on when it measures clean twice, not when you get bored of it.
Elbow drops at trophy
A low elbow shortens the throwing motion, so you push the ball instead of throwing the racket up at it. Serves land short or in the net and the shoulder takes the load.
“Elbow up to the shoulder line, hold, then swing.”
Measured, not claimed.
● Session 01 · Trophy
● Session 12 · TrophyYour baseline and every session after it land on one trend line, and the fault we flagged should shrink faster than the ones we didn't. Example shown: measurements from Repgroove's engine on AI-generated footage.

When you're readyYour video never leaves your phone.
Pose estimation runs on the device. What we analyse is joint positions over time, like the lines on the left, plus one still frame from the clip. The video itself stays with you.
Built with coaches, for every skill.
Each skill is its own pack.
Phases, faults, cues and drills for each skill, drafted from public coaching knowledge and refined by partner coaches. A tennis player and a basketball player each get an app that feels built for them.

Asked, answered.
Do I need a camera?
No. Pick your skill, do the two-minute baseline, and you get a plan with one fault and one drill today. Add video whenever you're ready, from any phone or action-cam clip.
Does my video get uploaded?
No. Pose estimation runs on your phone, so the video never leaves it. Only the skeleton (joint positions over time) and one still frame are sent for analysis.
Is the player in the video real?
No, the footage is AI-generated to illustrate a full before-and-after. The analysis is real: every angle and flag shown is what Repgroove's engine measured on it.
Which skills?
Right now: Tennis (serve, forehand, backhand, forehand, from behind, backhand, from behind); Golf (swing, face-on, swing, down the line); Pickleball (dink); Basketball (free throw, jump shot); Running (stride); Swimming (freestyle); Baseball (pitching); Volleyball (serve, spike); Soccer (shooting); Strength (deadlift, bodyweight squat, bodyweight squat, front view). Swimming is plan-only for now: phone pose tracking struggles through water, so freestyle coaches from your answers and check-ins until a swim-trained model is ready. Each new skill is a pack, not a new app.

Yes. It's $1 for your first week, then $19 a month, billed monthly. Cancel anytime.
