YouthArmCare
A pitch-count and velocity-logging app for Little League, travel-ball, and high-school pitchers that warns parents and coaches when a young arm is being overused, based on research into Tommy John surgery risk factors.
Parents and coaches of youth baseball pitchers (ages 10–18) worried about overuse injuries
- Quick log after each outing: pitches thrown, peak velocity, innings
- Personalized workload dashboard with rest-day guidance per age group
- Warning alerts when weekly pitch counts or velocity spikes cross safe thresholds
- Team view for coaches managing a full pitching rotation
With MLB stars like Sasaki regularly hitting 100+ mph, the cultural conversation about pitching velocity is intense, and parents increasingly worry their kids are following risky trends.
Multiple authoritative sources document a 500% rise in Tommy John surgeries among 15-19 year olds (2000-2015) and sustained media coverage of youth overuse, validating real parental/coach anxiety.90+ Tommy John Surgery Statistics (2026, Verified) ↗Tommy John surgery is more common than ever ↗
Market is crowded: at least five commercial incumbents (Pitch X, GameChanger, PitchSync, Better Pitch, Arm Care), plus league-mandated tools (OBA Pitch Count); PitchSync already targets workload/overuse management, and Pitch X bakes in Pitch Smart guidance, leaving little uncontested territory beyond velocity logging.Top 5 Pitch Count Apps for Protecting Pitchers ↗Baseball Ontario Pitch Count – Google Play ↗
Willingness to pay exists (parents in travel ball pay for tools, GameChanger and similar apps run tiered subscriptions), but free league apps and GameChanger's free tier compress pricing power; unproven that a standalone warning app can command premium without velocity-radar upsells.GameChanger App – App Store ↗Top 5 Pitch Count Apps for Protecting Pitchers ↗
Tommy John concern and velocity culture are durable, multi-decade trends with ongoing clinical and media coverage; arm-care guidance (Pitch Smart) is codified by MLB and unlikely to fade.Why More Teens Are Undergoing Tommy John Surgery ↗
Core pitch-count + rest-rules + parent alerts is straightforward to build; however, the velocity-logging differentiator requires radar hardware (Rapsodo/PitchLogic ~$200-500) or video biomechanics, materially raising complexity and limiting passive data collection.Pitch AI: Arm Care | Throw Harder & Stay Healthy ↗
