Sleep Log App, Insomnia Tracker, Sleep Planner (Digital Download)

About this product

One file. You double-click it and it opens in the browser you already use.

There is no account to make, nothing to install, and no subscription that can be switched off later. Everything you type stays in that browser, on that device. It works offline for good.

TWO MINUTES A MORNING
The time you put the light out and the time you got up. A rating out of five if you feel like it. That is the whole daily job - the hours, the efficiency and every chart come out of those two times, and none of them are ever typed in.

SET UP IN ONE CLICK
It reads your language, your date format and your first day of the week from the browser and fills them in. You look at four lines and press Start. Under 30 seconds from opening the file, and it opens already filled in with four months of example nights so no chart is blank while you look around.

• WHAT IT DOES
• Tonight, last night, the week: one screen a morning, and it remembers where you were
• The month as one bar per night, drawn between the real clock times rather than as a bar chart of hours
• A 24-hour clock ring for every night, and one for the night you usually have
• The whole year as one square per night, so a bad fortnight looks different from a bad year
• Sleep efficiency, time asleep, minutes awake and your midpoint, worked out the way a sleep service defines them
• Every factor you track ranked by how much difference it actually makes to you, with the night count printed beside each claim
• One factor at a time: caffeine, alcohol, screens, exercise, stress, the room - your own nights either side of the change
• Sleep debt against your own target, never against a fixed eight hours somebody else chose
• A wind-down you build yourself, ticked off nightly, with the nights you kept it set against the nights you did not
• The two-week diary a sleep clinic or a course of CBT for insomnia asks for, filled in already and laid out for paper

IT EXPLAINS ITSELF
A full guide lives inside the app, in your language, with an entry for every screen: what it is for, what to type, what the numbers mean, and what to do when it looks wrong. It has a search box and it works offline like everything else. A one-page start guide is in the download as well.

YOURS TO ARRANGE
Ten colour schemes, each in light and dark. Six languages, all inside the same file. The tabs collapse to icons, and you can reorder them, rename them into your own words, hide the ones you do not use, and choose which one opens first.

IT NEVER LOSES YOUR WORK
One button writes a backup file. Copy that file and the app to another computer, press Restore, and everything comes with it - nights, settings, colours and your tab layout.

AND ONE MORE VERSION, FREE
A card inside the download takes you to a page where you pick one of these four, at no extra cost. It downloads straight away - your name and email, and no order number to find.

1. Notion - A zip you import into your own workspace. Six real databases with an example fortnight already in them.
2. Excel - A multi-sheet workbook with live formulas and no macros. Opens in Excel, LibreOffice and Google Sheets.
3. Printable - US Letter and A4, undated, print-ready margins. Every section prints on its own.
4. GoodNotes - A landscape tablet PDF, fully hyperlinked. Works in GoodNotes, Notability and Noteshelf.
WHAT ARRIVES
One small zip: the app, the one-page start guide, and the card for your free version. It downloads the moment you buy.

A sleep diary is a record, not a diagnosis. Nothing here is medical advice and nothing here is measured for you - it is designed to be handed to a doctor or a sleep service, which is exactly what they ask for.

FAQ

Do I need an account?
No. There is nothing to sign up for and nothing to remember. The file does not talk to anything.

Does it work offline?
Yes, always. Nothing is fetched and nothing is sent, so a plane, a hotel or a dead connection makes no difference.

Which browsers does it work in?
Chrome, Edge, Firefox and Safari, on Windows, Mac, iPad and Android. It is a web page, so whatever opens web pages opens this.

How long does setting it up take?
Under 30 seconds. It reads your language, date format and first day of the week from the browser, you check four lines and press Start.

Does it connect to a watch or a ring?
No, and that is deliberate. This is a sleep diary - the two times you write down in the morning are what a sleep service asks for, and no wearable produces that form for them.

Is there a guide?
Two. A one-page start guide in the download, and a full guide inside the app with an entry for every screen and a search box - in your language, and it works offline.

Can I move it to another computer?
Yes. Press Back up to write one small file, copy it and the app across, and press Restore on the first screen. Nights, settings, colours and your tab layout all come with it.

How do I get the free version?
A card in the download has a link. Press it, pick one of the four, give a name and an email, and it downloads. There is no order number to find.
