Old pitch communication breaks under pressure.
Hand signals get missed. Communication gets noisy. Timing slips. In close games, small delays turn into big mistakes.
Seam sends real-time pitch calls from the dugout to the catcher's wrist, logs every outcome with full count context, and clocks live MPH from Pocket Radar Smart Coach — all in one game-day flow.
Software only: Seam does not include hardware devices.
Call It — live pitch calls to Apple Watch
Log It — outcomes, count, and session history
Clock It — live MPH with Pocket Radar Smart Coach

Setup Guide
This guide walks coaches through getting live pitch speed (MPH) from a Pocket Radar Smart Coach radar into Seam during a game. Follow the three parts in order.
Speed travels through four links. All four must be healthy for a reading to reach Seam:
Smart Coach Radar
Measures speed
Pocket Radar Sports App
Bluetooth bridge, live session
Pocket Radar Cloud
Broadcasts to authorized partners
Seam
Shows MPH on the count card
Key point
The Pocket Radar Sports app is the bridge between the radar hardware and the cloud. It must be open and in an active live session for speeds to flow to Seam. If the Sports app is closed or not in a session, the radar has no path to publish speeds — Seam will show nothing, even if everything else is connected.
Seam receives speeds from the cloud, not directly from the radar. The Sports app and Seam can run on the same phone or two different devices — and Seam works on iPhone, Apple Watch, or iPad.
Before you start, make sure you have:
Confirm your Pocket Radar account is set up correctly and authorize Seam.
Authorizing Seam is a one-time action per account. You only need to redo it if you disconnect Seam or switch Pocket Radar accounts.
Now link the same account inside Seam.
If Seam can't find your account: it means the authorization from Part 1.3 hasn't reached Seam yet. Re-open Pocket Radar Connect, make sure Seam shows as connected, then try again in Seam. Allow a few seconds between authorizing and connecting.
Confirm a real speed reaches your device before game day.
If the test times out with "No speed received":
Once the checklist is all green, there's nothing else to do:
A live status dot on the velocity card shows the connection state:
