Sleep Log
One night tells you almost nothing. A week of bedtimes, wake times, and how you felt shows the real pattern — and the Restcalc Sleep Log turns those few taps into a visual trend you can actually read.
Why track at all
Memory lies about sleep. You think you slept fine, but the log shows a 90-minute variance night to night. Seeing the pattern is the first step to fixing it.
Tracking also makes the calculators useful — you can check whether a new bedtime actually helped.
What the trend shows
The log plots each night's duration and cycle count, plus your "felt" rating. Over a week you see average duration, consistency, and whether late nights correlate with worse mornings.
The Sleep Log renders this as a simple trend you can read at a glance.
Consistency beats total
Two people with the same average hours feel different if one varies by two hours and the other is steady. A stable schedule is the single biggest lever for feeling rested.
The log makes that variance visible, which is the whole point.
Turning insight into action
If the log shows a late-weekend slide or a mid-week dip, shift one anchor — usually wake time — by 30 minutes and watch the trend move.
Pair it with the Bedtime Calculator or Wake-up Calculator to plan the change.
Tips for useful logging
- Log within 10 minutes of waking, while it is fresh.
- Use the same "felt" scale every night.
- Aim for a steady wake time above all.
- Review the week, not the single night.
