BP Log7-day home blood pressure average
A guided 7-day home blood pressure log: two readings morning and evening, day 1 set aside, the rest averaged. Saves your progress in this browser and prints a summary for your doctor.
Your 7-day home log
Each morning and evening, sit quietly for 5 minutes, then take two readings a minute apart and enter them here. Your progress stays in this browser, so come back each day. Day 1 is set aside because first-day readings tend to run high.
Home blood pressure, 7-day average
Days 2 to 7 averaged; day 1 set aside.
Your average will show here from day 2.
Made with the free 7-day home blood pressure tool at bplog.cc/tools/home-blood-pressure-average. Descriptive only, not a diagnosis.
Why a 7-day average
A single reading at the doctor’s office is one moment, often a stressful one. A week of home readings shows your usual blood pressure. The 2025 ACC/AHA guideline recommends home readings to confirm a diagnosis and to see how treatment is working, and the AHA’s measurement statement describes the protocol this tool follows.
How to do it
- Use a validated upper-arm cuff that fits your arm (see the cuff size finder).
- Each morning, after using the bathroom and before medicine, food or coffee, sit quietly for 5 minutes with your back supported, feet flat and arm resting at heart level.
- Take two readings about a minute apart and enter both.
- Each evening, before bed, do the same.
- Repeat for 7 days. This page remembers where you are, so you can come back each day.
How the average is calculated
The tool uses the shared code library behind the BP Log apps. It sets aside every day 1 reading, takes up to two morning and two evening readings from each of days 2 to 7, and averages the top numbers and the bottom numbers separately. The headline average is rounded to whole numbers, and its category comes from the same 2025 ACC/AHA classifier as the category checker. A full week gives 24 readings in the average.
When you finish, print the summary or download it as a CSV file and bring it to your appointment. Our guide to sharing home readings with your doctor explains what to bring.
Common questions
Why are day 1 readings left out of the average?
Readings on the first day of home monitoring tend to run higher, partly from unfamiliarity with the routine. Standard 7-day protocols set day 1 aside and average days 2 to 7.
What if I miss a morning or an evening?
Keep going and fill in what you can. The average uses every reading from days 2 to 7, so a missed session makes it a little less steady rather than wrong. The summary shows how many full days you logged.
What home average is considered high?
Under the 2025 ACC/AHA guideline, a home average of 130/80 or higher is in the same range as an office reading of 130/80 or higher. The summary shows which category the average is consistent with, for you and your doctor to discuss.
Where are my readings saved?
Only in this browser, on this device, using its local storage. Nothing is sent to BP Log or anyone else. Clearing your browser data or using a private window removes them, so print or download the summary when you finish.
Should I take two readings each time?
Yes. The AHA recommends two readings about a minute apart, morning and evening. The second reading is often a little lower than the first, and averaging both gives a truer number.

Measurement of Blood Pressure in Humans: A Scientific Statement From the American Heart Association (Hypertension, 2019): How to measure; home protocol of 2 readings a minute apart, morning and evening, for 7 days; cuff sizes by arm circumference; white coat and masked hypertension definitions; home 130/80 corresponds to office 130/80

- Self-Measured Blood Pressure: How It Works (Target:BP, AHA and AMA): Morning and evening for 7 consecutive days, two readings one minute apart; home average of 130/80 or higher is in the stage 1 range
The free iPhone app times two readings a minute apart, averages them, keeps your morning and evening numbers apart, and builds a report for your doctor.
