A smart field starts with one iPhone
HeyBLU anchors ball/strike feedback to home plate in 3D—live audio, pitch location, and session data from one iPhone. Add a second device when your crew wants a bench view or remote control without touching the primary phone.
We built HeyBLU for bullpens and practice. Leagues and UICs exploring scrimmages, fall ball, or structured in-game pilots are welcome—we’ll help you design crew workflow and what “assist” means at your level.
Two roles, one field
Primary (Track Game)
Umpire iPhone
Live ball/strike audio for taken pitches, on-screen location, and session data. Human umpire still owns swings, runners, and game flow.
Secondary · Follow Game
Bench or press box
If a subscriber shares their live pitch location feed, non-subscribers with the same HeyBLU app can “Follow Game” with their own iPhones.
Secondary · Command Center
Coach or operator phone
Run the pen from a second iPhone or iPad—zone adjustments, pitcher changes, and session control without touching the primary phone.
What a smart field gives you
- Plate-anchored 3D strike zone — not a flat video overlay; geometry locked to the real dish.
- Live ball/strike audio — instant feedback; many umpires use Bluetooth earbuds so only the plate ump hears the assist.
- Pitch location logging — every tracked pitch captured for review, export, and umpire training.
- Operator tools — pause/resume, delete last pitch, active pitcher tagging, Command Center, session exports.
- Honest limits — swings stay with the human umpire or coach.
Suggested path for leagues
- 1.Start in bullpens and umpire zone clinics—UIC and coaches download the app and try pitch tracking together.
- 2.Add Follow Game (watch only) or Command Center (full control) when your crew is ready for a second device.
- 3.Pilot scrimmages or fall ball when stakeholders agree on zone size and who hears audio.
