FAQ

Questions Caffeine Countdown Clock owners ask.

  • 01

    How does the calculation work?

    The capability uses the caffeine half-life (typically 5.5 hours) and a set number of clearance cycles to calculate when your body will have processed enough caffeine to allow for deep sleep.

  • 02

    Can I customize the half-life duration?

    Yes, you can provide a specific halfLifeHours value to the capabilities if you know your metabolism is faster or slower than average.

  • 03

    What does 'High Risk' mean?

    A High Risk status indicates that more than 30% of the caffeine consumed is estimated to still be in your system at your target bedtime.
