SeamCall

Seam is the real-time pitch calling app for baseball and softball coaches who demand faster communication, cleaner execution, and smarter in-game decisions.

Stop relying on hand signals that get missed. Seam sends pitch calls and offensive plays from your iPhone to your catcher's Apple Watch in seconds — with count, outs, and inning on every call.

HOW IT WORKS

Open Seam on your iPhone, your catcher opens it on Apple Watch. Confirm the connection. Start your game. Call every pitch with one tap. Your catcher feels the haptic, reads the call, and gets set.

With Seam Team, connect up to 10 Apple Watches at once — catcher, pitcher, base coaches, and bench all receive calls over Bluetooth. No extra iPhones needed.

CALL PITCHES IN REAL TIME

Tap any pitch from your customizable grid and it delivers instantly. Fastball inside. Slider down. Changeup up. Curveball low. Intentional walk. Pickoff. Mound visit. One tap away.

OFFENSE MODE

Call plays from the dugout when your team bats. Bunt. Take. Swing Away. Hit & Run. Steal. Squeeze. Delayed Steal. Sacrifice. Ten plays sent to watches instantly. In Team Mode, batter plays route to your hitter while runner plays go to baserunners. Urgent calls display in red. Track your lineup, current batter, and on-deck hitter in-game.

PITCHER PROFILES

Save custom signal sets per pitcher. Switch with one tap at a pitching change. Each profile stores its own labels, ordering, and urgency settings. Duplicate for quick variations. Sorted by most recently used.

REPEAT LAST CALL

One tap repeats your previous call without navigating your grid. Built for pace and pressure.

FULL AT-BAT CONTEXT

Every call carries count, outs, and inning so your battery stays aligned on every pitch.

OUTCOME TRACKING

Log every result — strike, ball, foul, hit, or out — with automatic count advancement. Mark offensive plays as Executed, Missed Sign, or Cancelled.

COMPLETE PITCH HISTORY

Every pitch and play logged automatically. Review your timeline during the game, between innings, or after the final out.

DASHBOARD ANALYTICS

Pitch mix, strike rates, first-pitch strike rate, and activity across every game. Filter by date range, signal category, or pitcher profile.

PER-GAME DEEP DIVE

Open any past game for pitch breakdown by inning, by count, outcome patterns, and offensive execution rates.
