Score every pitch. Own every game.
DiamondKing is the game-scoring and pitch-tracking app built for the dugout — every pitch, at-bat, and base runner logged on your phone, with the strike zone live on your wrist.
Coming soon to the App Store · iPhone + Apple Watch
The Toolkit
Built game-first: fast enough to keep up with live play, deep enough to tell you something afterward.
Log pitches, at-bats, substitutions, and base runners in real time — designed for one-handed speed between pitches.
Chart every pitch location in the strike zone. See where your pitcher lives — and where hitters hurt you.
Walk away from every game with the story in numbers: scoring, pitch counts, and at-bat results, saved and reloadable.
Lock in a pitch on the phone and the zone grid lights up on the wrist. Signals without saying a word.
Your whole staff on the same page — shared game data across coaches, powered by iCloud.
Games are saved on your device and stay yours. Reload any past game, any time.
See It In Action
Real screens from the app — the launch, the pitch call, and every game saved.

No spam — just beta invites and launch news.
The Story
DiamondKing wasn't designed in a boardroom. It's built independently, game by game, by a founder who got tired of paper scorebooks, tipped signs, and stat apps that can't keep up with live baseball.
Every feature ships because a real game needed it. Interested in partnering, investing, or piloting DiamondKing with your program? Get in touch.
The name honors the Diamond Kings — the ball club where it all started.
