A Cooper test timer on your TV, for training too
The ScoreboardCast timer shows the time left or the time elapsed on a big TV, readable from anywhere in the hall. The teacher starts and stops it from a phone, and at the end of the countdown the TV sounds the horn.

Countdown or stopwatch
For a countdown, 5, 10, 15 or 20 minutes are one tap away, or any time to the minute and second. For the Cooper test it is 12 minutes. As a stopwatch the TV shows the time elapsed. In the last minute tenths of a second appear too.
Adjust while it runs
Seconds or minutes can be added or taken away while it runs, and the clock can be paused and resumed at any time. The TV keeps time on its own clock, so it stays accurate even if the phone locks.
For PE class and training
It also works for circuits, timing breaks, stretching or any timed game. For intervals use the Tabata interval timer, for the endurance test the beep test.
What you need
- A Google Cast-enabled TV, or any TV with an external Chromecast
- An Android phone with the free ScoreboardCast app
- Wi-Fi that both the phone and the TV are on
The TV checker tells you in two minutes whether a given TV works. In a gym the TV should sit behind a ball guard.
