How to use the circuit training timer
Name each station and set its duration. Choose rest between stations, the number of circuit rounds, and an optional preparation countdown. The next exercise name stays visible during your current station.
Rest is inserted between stations, including the last station of one round and the first of the next. There is no extra rest after the final station of the final round. Individual station lengths can differ, so a long hold and a short drill can share one circuit.
Can I use this for a station rotation outside the gym?
Yes. Names and durations are freeform. You can time practice stations or group activities with the same sequence. For a teacher-led lesson with manual advancement, try the classroom timer.
What happens if I refresh or switch tabs?
Running timers are recovered from saved timestamps after a refresh. They catch up to the elapsed schedule without replaying a stream of missed sounds. In manual-transition mode, the next step waits for you. Keep the page open and test your sound: background throttling, sleeping devices, or closing the browser can delay or prevent an alert. Changing the device clock can affect recovery after a reload.
Do I need an account?
No. Settings and the current session stay in this browser. They are not synced to an account. Clearing TimeCubby data removes them. Sounds are generated locally, with no audio files downloaded or uploaded.
