Who’s running the clock today?
All the parents suddenly get interested in their coffee. You've got volunteer hours left, so... it's your turn.
- Entered the wrong penalty because player number is less than 10
- You can't figure out how to clear the penalty
- Put up a time-out, can't get game time back...
- Horn honks randomly and you don't know how to stop it.
How It Works
At venues with a BlitzBox installed, you're up and running in under a minute.
Scan the QR Code
Each BlitzBox has a QR code on it. Scan it with your phone to open the free BLITZ app — no account required.
Connect via Bluetooth
The app pairs with the BlitzBox in seconds. Select your sport and you're connected to the scoreboard.
Run the Clock
Tap to start, tap to stop. Penalties, timeouts, and period changes are all one tap. The scoreboard updates instantly.
Why Parents Love It
- One-tap clock control — Start, stop, and reset with a single tap. No buttons to hunt for.
- Automatic horn — Period ends and the horn sounds on its own. No more missed buzzers.
- Penalty tracking built in — Tap the player number, select the penalty, and the clock handles the rest.
- Works on your phone — iPhone, iPad, or Android. No special hardware in your hands.
- Free to use — The app costs nothing. The BlitzBox hardware is a one-time venue cost.
