We build software for volunteer and club coaches who'd rather focus on their players than paperwork, spreadsheets, and last-minute lineup math.
Get Game Day Coach Learn Our StoryMost coaches aren't professionals with a staff behind them — they're parents, volunteers, and teachers giving up their evenings and weekends. The Tsunami Experience builds tools that take the busywork off a coach's plate — rosters, lineups, substitutions, scheduling — so more energy goes toward the team and the game, and less goes toward spreadsheets and sticky notes on a clipboard.
Game Day Coach, our flagship app, is built around the four things every team manager juggles every single week.
Track your full roster, positions, and skill ratings in one place — no more guessing who's played where or who's due for more time.
Set your team identity, track opposing teams, and switch between formations like 4-3-3 or 4-4-2 as your roster and opponents change.
Plan every game of the season with home and away tracking and a starting lineup ready to go before you even arrive at the field.
Opponent previews, a live game clock, and goal tracking — everything you need in the moments that actually matter.
The hardest part of coaching youth sports isn't drawing up a formation — it's knowing when to make the sub. Game Day Coach does that math for you, in real time.
Every player on your roster gets a talent score from 0–100, built from their skills and position ratings — no more relying on gut feel alone.
Rate opposing players on Speed, Power, and Skill so your lineup decisions account for who's actually across the field, not just your own side.
Log goals, assists, good moments, and injuries as they happen — the engine adjusts sub timers and recommendations to keep your team balanced all game long.
Game Day Coach is built for the coaches who show up every practice and every game — this is our way of showing up for you.
