iPhone
Keep your full reading history and export a clean doctor PDF. Log your blood pressure in seconds with big, clear numbers. Calm, private, and easy to use.
Pressure Diary is the calm, senior-friendly way to track your blood pressure at home. Log a reading from your own monitor in seconds with big, clear numbers, then see your trends at a glance.
Unlike other apps, your full history is ALWAYS free. We never lock your old readings behind a subscription, and a CSV export of your readings is free too.
WHAT YOU GET FOR FREE
- Log systolic, diastolic and pulse with large, easy buttons
- Keep your complete history, with no limit and no paywall
- Tag readings: morning or evening, left or right arm, before or after medication
- See clean trend charts over 7 and 30 days
- Export a tidy CSV spreadsheet of your readings for your doctor, anytime
- Set an optional daily reminder so you never forget to log
INR (WARFARIN) LOG
If you take warfarin, keep your INR results in the same app, in a separate INR tab that leaves the blood pressure log untouched:
- Log each INR blood-test result with the date and time, an optional warfarin dose in mg, and a note
- Set your own target range (default 2.0-3.0, or any range such as 2.5-3.5) and see at a glance whether a result is below, in or above it
- A 90-day trend chart with your target band, plus time in range and your latest value on a summary card
- INR results are included in the doctor PDF report and the CSV export
The INR log only records what you enter. It never measures INR and never calculates or recommends a dose.
PREMIUM (optional)
- Doctor-ready PDF report export
- Track multiple people in one app
- Deeper analytics: morning vs evening averages and longer history
- Lifetime option: pay once, no subscription
IMPORTANT
Pressure Diary is a logbook for readings you take with your own blood pressure monitor. It does not measure blood pressure and is not a medical device. It is for information only and is not medical advice. Always talk to your doctor about your readings.
Your data stays on your device. No account, no tracking, and we never sell your data.
SUBSCRIPTION
Pressure Diary offers a weekly subscription with a 3-day free trial, an annual subscription with a 3-day free trial, and a one-time Lifetime purchase. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions automatically renew unless cancelled at least 24 hours before the end of the current period. Manage or cancel subscriptions in your Apple ID Account Settings. Restore purchases anytime from the app settings.
