Signal Call is a wireless pitch calling system that lets baseball and softball coaches send pitch signals directly to a catcher's Apple Watch.

No more complicated hand signals. No more runners stealing signs. Just tap your phone, and your catcher sees the pitch type and location instantly on their wrist.

----------------------------

HOW IT WORKS

1. Use your existing paired Apple Watch and iPhone
2. Select a pitch type (Fastball, Curveball, Changeup, etc.)
3. Tap a zone on the 3x3 strike zone grid
4. Your catcher sees the call instantly on their watch

The watch displays pitch type, location, and a visual zone grid with color-coded pitch categories. A vibration alert ensures the catcher never misses a call.
