Four Features Nobody Else Has
We didn't build another scoreboard app. We built the platform you wish existed when you were stuck with clipboards and group texts.
Collectible Player Cards & XP
Your players earn XP with every hit, strikeout, and stolen base. Their cards level up from Rookie to Legendary across 6 tiers. Collect 200+ Diamond Legend cards. Complete the set? Order a printed deck delivered to your door. No other platform does this.
- Cards auto-generate from real game performance — no setup needed
- XP system rewards every at-bat, strikeout, and stolen base
- Six tiers: Rookie → Starter → Champion → Legend → Mythic → Diamond Legend
- Complete a full collection and order a printed deck at home
The Easiest Scorekeeper in Baseball
Anyone can score a full game — a parent in the stands, a teenager in the dugout. Tap-to-score updates stats, spray charts, and play-by-play in real time. This isn't basic scorekeeping — it's analytics.

- Pitch tracking with live heat maps and tunneling detection
- Spray charts update after every single at-bat
