Cancel a game in 10 seconds. Track court time without a stopwatch. Rebuild a carpool when the rain hits. The 3 game-day stress points, in one tool.

Problem

Coach в день матча в 9:30 утра отменяет игру из-за дождя — должен достучаться до 14 семей через 4 канала (TeamSnap + WhatsApp + SMS + email) и вручную звонить тем, кто не подтвердил. Параллельно во время игры считает rotation минут на боковой линии, чтобы потом доказать родителям, что Джонни сыграл столько же, сколько Сэм. И на выезде — карпульная ротация рушится при изменении расписания.

Audience

Volunteer head coaches и parent-coordinators youth-sports команд (5-14 семей) в США — обычно работающие по основному месту работы и тренирующие вечером

What we ship

**Core features (MVP)**

  • Cross-channel broadcast (one tap → SMS + email + push), per-family read receipts, voice-call fallback
  • Court-time tracker: roster + sub-clock with rotation rules → CSV per game
  • Carpool rotation engine that rebuilds roles when schedule changes
  • Read-receipt dashboard
  • No-account family view (parent clicks SMS link)

**Primary user flow**

1. Coach imports roster (CSV or TeamSnap)

2. Builds season schedule + auto-generated carpool rotation

3. Game day rain → tap "Cancel game" → broadcast in 10s

4. Read-receipt dashboard → call 2 unreached families

5. At game: rotation tracker, one-tap substitution

**What it looks like**

  • **Landing**: 3-up "Cancel a game / Track court time / Rebuild a carpool" with demo videos
  • **Coach dashboard**: today's game card + 3 quick actions
  • **Family link (no account)**: "Game cancelled. Next: Sun 4/29 vs Eagles"

**MVP build plan (14 days)**

  • Day 1-3: schema, auth, Stripe
  • Day 4-7: broadcast engine + Twilio SMS/voice + read-receipts
  • Day 8-10: court-time tracker (mobile-first), CSV exports
  • Day 11-12: carpool rotation engine + reschedule rebuild
  • Day 13-14: landing, deploy

Reasoning

Three tightly related signals describe the same coach across three game-day stress moments. Existing tools (TeamSnap, GameChanger, SportsEngine) are admin/comms generalists; none model cross-channel broadcast with read-receipts, in-game rotation tracking, or carpool rebuild. "Court Time" iOS solves only one. Bundling the three is a novel wedge. Voice-fallback + read-receipts are sellable differentiators. 14 days is at the upper bound but each engine is MVP-feasible alone.

Quick competitive read

  • **TeamSnap** ($12-30/mo): no rotation tracking, no read-receipt broadcast
  • **GameChanger**: stats, not operations
  • **SportsEngine**: heavy league tier
  • **Court Time** (iOS): narrow rotation tracker
  • **Carpool to School / general carpool apps**: generic, not rotation-aware

White-space: integrated 3-in-1 game-day coach utility. **Competitive pressure: 5/10**.

Initial pricing hypothesis

Free up to 8 families (rec leagues). Pro $9/mo unlimited + voice-fallback + carpool rebuild + read-receipts. Coach pays, parents free.

Distribution hypothesis

Reddit r/CoachingYouthSports, USYS/AYSO league newsletters, Sideline Legends + Parendipity blog partnerships, TikTok/Instagram demos, SEO ("youth sports cancel game app", "fair playing time tracker").
