Blood Pressure Log
A private blood pressure log in one HTML file on your machine: no account, no cloud, no server to talk to.
This is not a screenshot. It's the real tool, running right here: go on, put something in it.
Forged into a knife, this tool ages with use: the blades you reach for wear soft, entries you tend keep their bloom, and the years travel with the file through every reforge.
The doctor said keep a record, and the scrap of paper lasted four days. The Blood Pressure Log keeps your readings properly — date, systolic, diastolic, pulse, and the moment you took them: Morning, Evening, or After the news. It is the tidy list you can actually bring to the next appointment.

Standing facts
- One HTML file. Opens in any modern browser, on any operating system.
- No account. No login, no sign-up, no e-mail wall.
- No cloud. Nothing leaves your browser: no server, no telemetry, no analytics.
- Yours forever. The file keeps working whether or not Offline.Ltd does.
- Ages with use. Entries you tend keep their bloom; the years travel with the file through every reforge.
In ten years
Whatever you put in (Date, Systolic, Diastolic and Pulse) stays inside the file itself. There is no account to lapse, no plan to be sunset, no migration e-mail with a deadline in it. A decade of blood pressure log entries is a decade of your own handwriting, kept in a document you can back up like any other.
If Offline.Ltd closes tomorrow, nothing on your machine notices. That isn't a marketing promise; it's simply what a file is.
Getting your data out
Export to CSV from inside the tool and open it in anything: a spreadsheet, another app, a text editor. Or keep the HTML file: it is plain, readable, and inspectable; you can open it in a text editor and see your own rows sitting there. No export queue, no "we'll e-mail you a link within 48 hours", no format that only one vendor can read.
Copy the file to a USB stick, a NAS, a folder your devices already sync. It runs on Windows, macOS, Linux, Android and iOS, online or off, because a browser is the only thing it ever needed.
Questions people ask
Is a blood pressure app safe for private health data?
This one keeps nothing anywhere but with you. It is a single HTML file that runs offline in your browser — no account, no cloud, no company holding your readings. They never leave the page, and the file is yours forever.
How do I record blood pressure readings for my doctor?
After each measurement you enter the date, systolic, diastolic, pulse, and the moment — morning, evening, or after the news. What you bring to the appointment is a clean, consistent list instead of a shoebox of guesses.
Why does the log ask when I took the reading?
Because blood pressure has moods, and morning readings and evening readings are different animals. Recording the moment lets you and your doctor compare like with like.
