Ace Pitcher: Log & Throw Throw harder this off-season. Ace Pitcher builds you a lifting and throwing program around your velocity goal, tracks every session, and protects your arm while you do it. YOUR VELOCITY PROGRAM Set a velocity goal and Ace Pitcher builds the program to reach it. Throw days, lift days, plyo work, and recovery, all sequenced to your season, your equipment, and where your arm is right now. Nothing generic. A plan built to move your number. LIFT, THROW, RECOVER Full video libraries for strength work, plyo balls, band care, and mobility. Every session in your program pulls from them, so you always know what to do and why it builds velocity. Guided timers walk you through each routine. ARM READINESS Every day opens with your readiness score, built from recent workload, how the arm feels, days since your last outing, and Apple Health data. It tells you when to push and when to back off, so you gain velo without breaking down. LOG EVERY THROW Bullpens, games, catch play, lifts, or a single velo reading. Logging takes seconds and feeds your readiness score, your weekly pitch count, and your velocity trend. Watch the gain build week over week in Progress. PITCH DATA, IMPORTED Scan a Rapsodo or TrackMan screen with your camera, upload a screenshot, or import a CSV. Ace Pitcher pulls in velocity, movement, spin, and release data and tracks it over time alongside everything else you log. GRIPS AND PITCH CALLING A full pitch guide with real grip photos and movement profiles by age level. Build your arsenal, then get a recommended pitch for any count, batter, and base situation, with the reasoning behind every call. AFTER THE OUTING Get a breakdown after every game and a weekly summary of your velocity, workload, and trends.
