Stolen signs
The opposing dugout has a phone, a coach, and time. Hand signals are leakier than they've ever been.

The dugout problem
Hand signs got slow. Wired comms got expensive. Coaches deserve better.
Old-school flashes get stolen. PitchCom-style hardware costs four figures a season. Yelling pitch numbers from the bench gets old by April.
Hardware sticker shock
Dedicated comms systems are $700–$1,400 a year for a single team. Most travel programs can't justify that.
Replaced · $1.99 on iOSGame-day chaos
Forgotten wristbands, dead AAA batteries, reverse-coding mid-inning. One more thing to manage on a bus day.

How it works
Three steps. No wires. Less than a tenth of a second.
The whole call-to-display loop runs over Bluetooth Low Energy, directly between the iPhone in your hand and the Apple Watch on the catcher.
Tap a pitch
Pick pitch type and zone on your iPhone — five-tap path from idle to sent.
Signal sent
Bluetooth Low Energy delivers the call directly to the watch — offline, no cellular, no router.
Catcher sees it
Pitch, zone, and sign number on the wrist with a haptic buzz. Glance, set, deliver.
Receivers
Start on the watch you already own.
Most programs start with the catcher's own Apple Watch and never need anything else. A dedicated long-range receiver is in development for programs that want to get the call to more than one player on the field — the pitcher and fielders, not just the catcher.

How it compares
The edge of wired comms. None of the cost.
Signal Call sits between stealable hand signs and four-figure audio systems — the speed and privacy of dedicated hardware, on a watch your catcher already owns.

Built by coaches
Made on the way home from a Saturday doubleheader.
Signal Call started as a side project for a 14U travel program that couldn't justify a four-figure comms system. The first version ran on a coach's iPhone and a catcher's hand-me-down Apple Watch. It worked the first inning. We never went back.
Today it's the same idea, polished — but it's still made for the people who run practice on Tuesday and call a game on Friday.
FAQ
Common questions.
Rules, requirements, and how Signal Call compares.
Is electronic pitch calling legal?
Rules vary by league. NCAA baseball and softball permit electronic devices for relaying signals from the dugout at all positions. NFHS (high school) generally permits coach-to-catcher signaling, with expanded use decided by each state association. Most travel organizations (USSSA, Perfect Game, Triple Crown, Game Day USA, NCS) allow it. Little League and Babe Ruth restrict on-field player receivers. Always check your specific league's most current rulebook. Full league-by-league breakdown →
Does the catcher need an iPhone?
No. The coach uses an iPhone in the dugout to call pitches. The catcher just needs an Apple Watch — the signal goes directly from iPhone to Apple Watch over Bluetooth. No phone is required on the field.
How does Signal Call compare to PitchCom?
PitchCom uses dedicated audio receivers and a wristband transmitter, with annual hardware costs typically running several hundred dollars per team. Signal Call is a one-time $1.99 on iOS — no subscription — and runs on the Apple Watch your catcher likely already owns. A dedicated receiver that reaches more than one player on the field — pitcher and fielders, not just the catcher — is in development.
Does it work without cellular service?
Yes. Signal Call uses Bluetooth Low Energy directly between the iPhone and the receiver. No cellular signal, Wi-Fi, or internet connection is required. It works in any dugout, indoor facility, or remote field.
How fast is the signal delivered?
The full call-to-display loop completes in under a tenth of a second. The catcher feels a haptic buzz on their wrist and sees the pitch type and zone instantly.
How much does it cost?
Signal Call is a one-time $1.99 purchase on the App Store — that unlocks unlimited pitch calling to an Apple Watch, yours forever, with no subscription. Signal Call Pro is an optional subscription that adds advanced analytics, pattern tracking, AI pitch suggestions, and CSV export. A dedicated receiver that reaches more than one player on the field is in development.
Is Signal Call a subscription?
No. Signal Call is a one-time $1.99 purchase — buy it once and unlimited pitch calling is yours forever, with no recurring fee. Signal Call Pro is a separate, optional subscription for coaches who want advanced analytics, pattern tracking, and AI pitch suggestions — but you never need it to call a full game.
What's the dedicated receiver, and how do I beta test it?
The dedicated receiver is a purpose-built, long-range device that reaches more than one player on the field — pitcher and fielders, not just the catcher — on a no-distraction display — in active R&D now. We're recruiting a small group of coaches to beta-test it: testers get discounted hardware and a direct line to the development team. Email hi@signalcall.app to join.
