Find out which evening habits actually help you sleep.
bedlog is a short diary: tick off your evening routine, note caffeine and screens, and rate how rested you feel in the morning. After a few weeks it shows you which habits go with your better mornings.

Why a diary
When sleep is bad, it is tempting to change everything at once — earlier bedtime, no coffee, no phone, a new pillow. If you sleep better, you do not know which change did it. If you do not, you do not know which one to drop. Writing down what you did each evening and how you felt the next morning is the simplest way to see what goes with what.
What you log
Evening routine
A checklist you can edit: screens away, lights dimmed, a wind-down activity, or anything you are trying.
Caffeine and screens
Each coffee, tea or energy drink with the time, and when the screens went off.
Morning rating
How rested you feel, from 1 to 5, plus bedtime, wake time and a note if you want one.
What you get back
Weekly view. Your last seven nights side by side: bedtime, routine, caffeine, screens and how you felt.
Patterns. For each habit, your average morning rating on nights you did it and nights you did not, with the number of nights behind each figure. A pattern only appears once there are at least three nights on each side.
Export. Download everything as CSV for a spreadsheet, or as JSON. It is your diary.
