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. Key Metrics (Examples) Hitting: Hip–Shoulder Separation (Sequencing “stretch”) Kinematic Timing (Hands After Hips) Bat Lag Proxy Angle Swing Plane Variance Stance Width Stability Head Stability (Vertical & Lateral) Pitching: Stride Length Ratio (normalized) Lead Foot Stability Near Release Arm Slot at Release Elbow Flexion at MER (Maximum External Rotation) Hip–Shoulder Separation Trunk Tilt at Release Head Stability Shared Timing Events: Foot Plant MER (Maximum External Rotation) Contact / Release (Wrist Peak Event) 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. Simple Workflow Record (or import) a clip Select Hitting or Pitching Let analysis run (fast, on-device) Review Efficiency & Subsystem scores Read strengths + top opportunities Add recommended drills to your training plan Re-test and track progress over time Designed For Youth & High School Players seeking structured improvement Collegiate & Travel Program Coaches scaling feedback Private Instructors wanting objective baselines Dedicated athletes tracking off‑season gains Privacy & Performance All biomechanical processing uses Apple’s Vision frameworks locally.
