Blood pressure, made legible

Know your
numbers.

VitaLog is a private health timeline built around blood pressure. Record a reading in seconds, see it against the target you set, and bring your clinician a log they can actually read.

Most health apps grade you against a chart. VitaLog grades you against the target you and your clinician agreed on.

Features

Everything blood pressure needs.
Nothing it doesn’t.

Record in two taps.

Big numbers, round buttons, and a rating that updates as you type. Morning, evening or yesterday.

Rated against your target.

Not someone else’s. Set 130/80, or whatever you agreed, and every reading is judged by it.

Trends you can read at a glance.

Your target as a band, not a threshold. See the week, the month, or the whole story, and when in the day you run high.

Medication, as a story.

Started, dose changed, side effect, stopped. Each with its own date, so the timeline lines up with your readings.

A log your clinician can read.

Days down the side, readings across. Export a CSV in one tap.

Forgot to log it? Back-date it.

Every entry asks: right now, or a past measurement? Shortcuts for this morning and last night.

Blood pressure comes first. Everything else is context.

Log the things that move your numbers, then see them side by side on the day they happened.

Privacy

Your health record.
Yours.

On your device first

Everything is saved in your browser before it goes anywhere. No account needed to start.

Locked with a PIN

VitaLog opens behind a PIN, so a borrowed phone does not mean a borrowed history.

Sync only if you want it

Add an email and the same log opens on your phone and laptop. Each account can only ever read its own records.

Leave whenever you like

Export a full backup or a clinician-ready CSV at any time. Erase everything in one tap.

Get started

Three steps. About a minute.

  1. 1

    Set your target

    Your name and the blood pressure target you agreed with your clinician.

  2. 2

    Choose a PIN

    Add an email too if you want the same log on more than one device.

  3. 3

    Add it to your home screen

    In your browser’s share menu, choose Add to Home Screen. It opens like an app and works offline.

See it with two months
of sample records.

The demo opens the real app as Ada, a made-up person with a story in her numbers. Change anything; it stays in your browser.
