When your own melatonin starts, the hour for your job, how long a dose stays up, and whether it works for you. A minute each.
The melatonin window
Your wake time on a free day and your job in: when your own melatonin starts, and the hour and dose to take it.
Your dose across the night
Guess first, then watch your dose against your own night: when it falls back under it, and what's left at your alarm.
The jet lag planner
Two cities and a date in: a card a day with when to take it, when to wear dark glasses and when to get outside.
The night shift planner
Your shift in: one day-sleep block, the light to dodge on the way home, and where melatonin fits.
Does it work for you?
Fourteen nights on and off it: whether your melatonin nights beat your normal night-to-night swing.
When should I take melatonin, and how much?
Eight taps: your window, your dose against the trials and a two-week test.
With Gyroscope One, snap the bottle when you take it and see your melatonin nights against your usual sleep, from your Apple Watch, Oura, WHOOP or Garmin. Open Gyroscope
