What Sets PitchKallr Apart

Purpose-built for softball coaches. Every feature designed around the reality of calling a game.

Intent vs. Outcome

Track what was called and what actually happened. See where your pitcher hit the zone vs. where they missed.

Spot Accuracy

Hit or miss tracking per pitch, per zone. Detailed accuracy analytics nobody else offers.

Batter Scouting

Tag batter weaknesses mid-game with quick traits. Build scouting profiles one at-bat at a time.

Apple Watch Display

High-contrast, sunlight-optimized display with haptic feedback. Designed to work at game speed, in any conditions.

Offline-First

Game State Tracking

Balls, strikes, outs, and innings — all managed automatically as you call pitches through the game.
