Your sleep log, without the spreadsheet upkeep
Log hours and a 1–5 quality score each day. The trend charts build themselves, and a CSV export is one click if you want the spreadsheet view.
How it works
Add sleep metrics
Sleep duration (hours) and Sleep quality (1–5 scale) are both in the template list.
Log after waking
Hours as a number, quality as one tap on the 1–5 row. Takes ten seconds.
Chart or spreadsheet, your call
Trend charts on the dashboard; export CSV opens the same data in Excel, Numbers or Google Sheets.
Why a browser tracker
Your readings are stored in your browser's local storage — no account, no upload, no analytics on your numbers. We can't see your data even if we wanted to. Export a CSV for the spreadsheet view, or a full JSON backup, anytime from the report page.
Questions people ask
Can I export my sleep data?
Yes — the report page exports every reading as CSV (opens in any spreadsheet) or a full JSON backup.
Does it track sleep automatically?
No — this is a manual log, which keeps it honest and battery-free. You enter what you know.
Do I need an account?
Never. There are no accounts at all; your log lives only in this browser.
