The clockface provides three warnings when your SleepTank® is getting low:

Bedtime: The time you should get to sleep

Critical: A low SleepTank® level indicates your mental effectiveness is significantly reduced compared to your fully rested state.

Empty: The SleepTank® level of zero indicates dangerous impairment equivalent to being awake for 24-hours and missing an entire night of sleep.

The SleepTank® clockface is ideal for workers who need to be alert on the job and can plan their sleep and naps accordingly. If your SleepTank® clockface indicates that you will be impaired when you need to be alert, such on the job or driving, then you can use the SleepTank® app to plan a nap to restore your level of alertness to be safe or go to bed early to replenish your SleepTank®.
