Features

Everything you need. Nothing you don't.

Designed for people who want a simple, private health log — not a complicated medical app. Large text, minimal steps, works completely offline.

  1. Feature 01

    Log in seconds

    Systolic, diastolic, pulse, arm, position, feeling. Defaults to last-used values. One tap to save.

  2. Feature 02

    See your trends

    Charts for 7, 30, or 90 days. Average, min/max, and feeling distribution for every period.

  3. Feature 03

    Share with your doctor

    Export a formatted PDF report or a CSV file. Works offline, saved directly to your device.

Privacy by design

Your health data stays on your device. Full stop.

Blood pressure readings are sensitive health data. We designed the app so they never travel over the network — not even to our own servers. Offline means offline: no cloud, no account, no sync.

  • Your readings never leave your phone

    Blood pressure readings, pulse, and feeling notes are stored only in your device's local database. There is no cloud sync, no server-side copy, and no account to sign into. Your health data belongs to you.

  • No registration, no account

    The app works out of the box without an email address or any sign-up. There is nothing to lose access to if a service shuts down.

  • Analytics are anonymous and opt-in

    This site uses Google Analytics for aggregate visit counts only — no health measurements, no ad tracking, no fingerprinting. Analytics load only after you accept the cookie banner.

FAQ

Common questions.

Is an account required?
No. The app works completely offline. There is no sign-up, no email, and no password to remember. Open the app and start logging.
Where is my data stored?
Locally on your device only. Your blood pressure readings are stored in the app's private local database and never sent to any server. No cloud sync, no backup to our infrastructure.
What does the $1.99 unlock include?
Permanent access to CSV Import/Export and PDF Report generation. It is a one-time purchase — no subscription, no auto-renew. Family Sharing is enabled so everyone in your family sharing group gets the unlock.
Does this work without internet?
Yes. Every feature — logging, charts, reminders, PDF and CSV export — works completely offline. Only anonymous analytics events queue locally and flush when you are connected, and those contain no health data.
