Diamond Trainer AI
AI Baseball Hitting & Pitching
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Level up your baseball or softball mechanics with AI-powered video analysis that auto-detects key phases and gives you clear drills to improve faster.
Diamond Trainer turns any iPhone or iPad into a personal baseball & softball performance lab. Record a swing or pitch, and let advanced on‑device vision models break down your movement—frame by frame—into the metrics college and pro coaches watch.
Why Athletes & Coaches Love It
Instant clarity: No guessing. Get objective “Efficiency” scores for torso, hips, hands/arms and total sequencing.
Actionable coaching: Each session produces strengths, top opportunities, and targeted drill recommendations.
Pitching or hitting: Switch modes to get discipline‑specific metrics and cues.
Fast & automatic: The app intelligently trims dead time, finds the key motion window, and detects dominant side.
Privacy first: Processing happens on device—your clips don’t need to leave your phone.

Smart Efficiency Scoring
Diamond Trainer goes beyond “one number.” Subsystem scores (Hands, Hips, Arms, Torso) roll up into an Overall Efficiency score—adaptive to experience level—while factoring data quality so low-confidence clips don’t unfairly punish you.
Personalized Drill Engine
Each improvement item can unlock a recommended drill (e.g., “Hands-After-Hips Tee Progression” or “Stride Box Drill”), with level‑specific hints (T-Ball → Professional) to keep development age‑appropriate and focused.
Data Quality Aware
The app detects when:
Athlete is too small in frame
Lighting or framing reduces pose confidence
Frame rate is insufficient around the action
You’ll see gentle guidance instead of random low scores.
