Call pitches from your iPhone to single watch or multiple watches! Your catcher gets them on Apple Watch — instantly. Real-time signals for coaches who play to win.
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

This app has potential of being good. It works well for defensive calls. I’m having issues getting my custom calls to show up on offense. I have reached out to customer support four times now with no response. I’m a paying member doesn’t seem to care about the customers.

Thank you!
BULLPEN MODE
A new Bullpen button on the dashboard. Call pitches, tag locations and read Pocket Radar velocity exactly as you would in a game, with the pitch count front and center. No fatigue alerts, and pens never count toward game pitch limits or season stats.
Tap History beside it to look back at every pen, per pitcher: strikes, balls, strike %, velocity, a location map, and every pitch with its speed and result.
KNOW WHO YOU'RE PITCHING TO
Set the opposing lineup once and it advances on its own as you record outcomes. A "Now Facing" row shows the hitter, which side they bat from, and how sure Seam is. Tap to correct it anytime. Every pitch is tagged with the batter.
ROSTERS FROM GAMECHANGER
Bring in an opponent's roster, or your own, from a GameChanger team link, QR code or screenshot. Save opponents ahead of time, pick your team once, and game setup just asks home or away and who's starting.
BASEBALL OR SOFTBALL
Set the sport once on each team. Every game is recorded as that sport, so baseball and softball numbers are never mixed.
SMARTER RADAR
• The catcher's throw back to the mound no longer lands on the next pitch. The faster reading always wins.
• Fix or remove any pitch's speed yourself. The radar won't overwrite a speed you set.
• A radar set to km/h is now converted to mph.
• Average and top velocity reset when you change pitchers.
TEAM MODE: CALLS THAT KEEP GETTING THROUGH
Every call goes out two ways at once: straight to each watch, and over the air to all of them. A player who steps behind the dugout keeps getting your signs. Automatic.
A JOIN CODE FOR YOUR WATCHES
Players enter a 4-digit code on their watch to join your session, so the team on the next field can't pick up your signs. It stays visible during the game for a watch that joins late.
BETTER ON THE WRIST
• A bigger sign and grid, sized to each watch. Easier to read on smaller models.
• Swipe for the count, outs, inning and score.
• Team Mode watches now have a pitch log.
• A clear Game Over screen when you end the game.
FASTER IN THE DUGOUT
• Send Again re-delivers a call to a watch that missed it, without counting it as a pitch.
• Undo and a collapsible list of recent calls sit right under the grid.
• Fix a mis-tagged pitch during the game or after.
• Custom offensive calls sit under Batter and Runner, and the built-in ones can be deleted.
• Select and delete several games at once.
THE IPAD IS NOW A COMMAND CENTER
• Pair it to your iPhone with a 4-digit code. No accounts or shared Wi-Fi.
• Build your Call Library there: pitches, defensive calls, and notes ("back leg", "for contact").
• Name the nine grid locations your way.
• Everything syncs to your iPhone, per team.
PRINTABLE REPORTS
A one-page Game Report for a pitcher and a season Pitch Analytics report, designed for paper and showing real sample sizes.
REDESIGNED ANALYTICS
Workload, Season Volume and Pitches by Inning now lead with the number that matters and the comparison that gives it meaning.
NOTES ON A CALL
Attach a short intent to any pitch and see it in your analytics and reports.
FIXES
• Connecting a player's watch no longer brings up an Apple "Bluetooth Pairing Request". Players only ever enter your 4-digit Seam code.
• Mound visits, pickoffs and intentional walks no longer count toward a pitcher's count or Arm Guard.
• A duplicate radar reading could land on the wrong pitch.
• A watch left open could show "ready" for a game it wasn't in.
• Two-word signs no longer cut off on the watch.
• Reports printed upside down.
• Players felt two taps for a single call.
• A watch could report wrong code tries nobody made.
• Calls could fail to send with nothing retrying.
• Calls arrived late while a player touched their watch.
