How to use the presentation timer
Set the length of your talk and two remaining-time thresholds: a first warning and a final wrap-up cue. Their text labels appear alongside the colors, so color alone never carries the instruction.
At zero, the display continues counting overtime instead of disappearing. Pause stops both the talk timer and overtime. This is a local speaker display on this device; it does not create a remote host room or synchronize other screens.
Will it keep showing how far over time I am?
Yes. The overtime counter continues until you pause or reset, up to the session limit. You can mute cues for a quiet presentation while keeping the visual warnings.
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.
