Bat speed for hitters. Pop time for catchers. Release point for pitchers. Glove work for fielders. Measured on your iPhone with custom AI models and true 3D body pose — not eyeballed from sampled frames. Then our coach tells you exactly what to drill tonight.
Custom-trained AI models + true 3D body pose give you measurements competitors only estimate — for every position, not just hitters. Our coaching AI then watches the full video and turns the numbers into honest, age-appropriate feedback.
Hitters: bat speed + exit velocity in MPH from our custom-trained bat-tracking model, calibrated against your kid's actual bat length. Catchers: pop time in seconds and glove-stability score from ball + glove tracking. Pitchers / throwers: release point and arm slot from 3D arm-and-glove geometry. Fielders: glove-out-front score. Every number age-banded so an 8yo isn't measured against an MLB line.
True 3D body pose runs on your iPhone, producing real 3D joint positions — not 2D projections that lie about rotation angles when the camera isn't perfectly square to the swing. Foreshortening-free hip rotation, shoulder rotation, hip-shoulder separation (the X-factor), stride length, knee flex, all measured with real geometry.
For swing sessions: tag Swing Start, Foot Down, and Contact — then see metrics anchored to the right moments. Negative Move, Pelvis Load, Max Separation, Forward Move, Pelvis Rotation Range, Separation at Foot Down vs Contact. The level of mechanical breakdown a $200/hour hitting coach would draw on a whiteboard, automated and scored against your age peers.
Different prompts for each position — a hitting coach for swings, a pitching coach for pitches, a catcher coach for framing and pop time, a fielding coach for first-step reads. The AI watches the full clip (not just sampled frames), uses the measured numbers, and returns honest verdicts (Excellent / Satisfactory / Off Target), tappable timestamps, one-line "practice feel" cue, and 3–5 drill recommendations from your weakest metrics.
Tell us your position (catcher, SS, RHP, OF, etc.), age, skill level, and equipment. We generate a 7-day plan paced for you, with a real rest day and 3–5 drills per session that match your position's needs — receiving drills for catchers, range work for shortstops, long-toss for pitchers, swing reps for hitters. The plan refreshes as your analyses show what's improving.
Bat speed, exit velocity, pop time, separation, stride length, arm slot — every measured metric trends across sessions on the Progress tab. Sparkline on each tile so you see the arrow without leaving the analysis. The numbers come from real geometry, so improvement is real improvement — not "you got better today" pats on the back.
Different positions get different measurements. The AI coach and drill recommender adapt to the session type you pick.
Five session types, ~20 seconds to record in 240fps slow-mo, ~10 seconds for AI analysis. Open app → see your bat speed before the kid's bat is back on the tee.
Tap session type → record. The app auto-captures in 240fps slow-mo for pro-grade frame density through the swing.
Three taps: Swing Start, Foot Down, Contact. Or skip to let the app auto-detect. Phase tags unlock pro-level metrics.
On-device: 3D body pose, bat keypoints, ball + glove tracking. Cloud: our coaching AI watches the full video and turns the numbers into honest coaching.
Drills picked from your lowest-scoring metrics. Daily plan refreshes as you improve. Progress charts show real measured gains.
"Finally something that tells me what to actually fix, not just 'great hustle'. My exit velo is up 4mph in six weeks."
"Tracked my pop time from 2.18 to 1.98 across one season. The receiving drills it picks after each catcher session actually moved the number — not random YouTube garbage."
"My son went from dreading practice to recording every backyard session. The frame-by-frame breakdown is no joke."
