Build a Youth Pitcher Arm-Health Video Analysis App

1. 1

   Set the medical boundary in concrete first

   This app informs; it never diagnoses, clears, or treats. Flags are 'patterns associated with arm stress in the research, worth showing your coach or a sports medicine professional,' full stop, and the disclaimers are written with actual legal and clinical review rather than copied boilerplate. Build a small advisory bench (an athletic trainer, a sports PT, a pitching coach) whose names stand behind the rubric. In a category involving children's health, the conservative product outlives the confident one, commercially and morally.

2. 2

   Analyze what phone video can honestly see

   Modern phones shoot slow motion good enough for meaningful mechanical review: arm slot consistency, timing sequence markers, stride and trunk patterns, and visible fatigue drift across an outing (velocity proxy dropping, release point wandering). Guide the parent to film from consistent angles, and report findings as observations with visuals ('arm position at foot strike trended later across innings') rather than scores that imply diagnostic authority the footage cannot support.

3. 3

   Make the boring tracking the daily habit

   Pitch counts per outing, cumulative workload, rest-day compliance, and multi-team totals (the travel ball trap where no single coach sees the whole load) tracked against the published age-based guidelines, with plain alerts when a plan would exceed them. The research is blunt that overuse and pitching through fatigue are the biggest modifiable risks; the app's most valuable feature might be the least glamorous one: a family-visible workload ledger across every team the kid throws for.

4. 4

   Serve the conversation, not the argument

   The output that matters is the shareable report: this month's workload, rest compliance, mechanical observations with clips, formatted for a coach meeting or a sports medicine visit. Position the app as the parent's organized notebook, never as ammunition against coaches; the product wins by making the adults around a young arm coordinate, and coach-facing team tiers (workload dashboards across a roster) turn potential adversaries into your best customers.

5. 5

   Price as a family subscription with a team tier

   Families pay in the range of $10 to $20 a month during season for analysis and tracking; teams and academies pay per roster for the coach dashboard. Seasonality is real, so annual pricing should acknowledge the off-season honestly (arm care and throwing-program tracking give the winter months a job). The buyer is a parent already spending heavily on travel ball; protecting that investment is a budget line they understand.

6. 6

   Earn distribution through the credibility ecosystem

   Youth baseball organizations, pitching instructors, athletic trainer networks, and sports medicine clinics that run injured young pitchers through their doors weekly. Content that leads with the epidemic's real numbers (sourced, not sensationalized) and practical guideline explainers builds the trust this category demands. A partnership with leagues to make workload tracking a norm, not a nag, is the long game that both grows the business and serves the actual mission.

Best for: A developer or sports-medicine-adjacent founder from the baseball world who will resist overclaiming

Not for: A builder who will overclaim to look impressive, because this is children's health and the conservative product is the one that survives. It is also not for someone with no baseball-world credibility, since the advisory bench and coach relationships are essential.
