What's inside

Where the color-coded ranges come from

The ranges follow the 2023 ESH Guidelines for the management of arterial hypertension (European Society of Hypertension). BP Diary shows which range a reading falls in; it does not interpret your readings or give advice. Ask your doctor what your numbers mean for you.

Pricing

Logging is free forever, including the last 7 days of history. BP Diary Premium adds your full history, 30 and 90-day trends and the doctor report: $2.99 a month, $14.99 a year, or $29.99 once for lifetime access. Prices are in US dollars; the App Store shows the price for your country. Older readings are never deleted on the free plan, only hidden until you upgrade.

Not a medical device

BP Diary is a logbook for self-measured values. It does not measure blood pressure and is not a medical device. Always discuss your readings with a healthcare professional.
