How to Use This Tracker

Log your sleep each morning for the best results. Here's what each field means:

  • Bedtime: When you got into bed with the intention to sleep
  • Time to Fall Asleep: Sleep latency - how long it took to fall asleep
  • Wake Time: When you woke up for the day
  • Time Awake at Night: WASO (Wake After Sleep Onset) - total time spent awake during the night
  • Quality: Your subjective rating of how restorative your sleep felt
  • Factors: Things that may have affected your sleep

Your data is stored locally in your browser. It won't sync across devices, but it's completely private.

Understanding Sleep Metrics

Sleep Duration: Total time actually asleep. Calculated as time in bed minus latency and WASO. Adults should aim for 7-9 hours.

Sleep Efficiency: Percentage of time in bed actually spent sleeping. A healthy efficiency is 85% or higher. Low efficiency often indicates insomnia or sleep disruption.

Sleep Latency: Time to fall asleep. 10-20 minutes is normal. Falling asleep instantly may indicate sleep deprivation; taking over 30 minutes may indicate insomnia.

WASO (Wake After Sleep Onset): Time spent awake after initially falling asleep. Some brief awakenings are normal, but frequent or long awakenings reduce sleep quality.
