Who we are, and how we work
bptrack.app is published by Anvil Road LLC. It exists to help one specific person: somebody whose doctor asked them to check their blood pressure at home, and who was not told how.
Reviewed 30 August 2026.
Why this site exists
Nearly half of American adults have high blood pressure — 47.7%, measured across August 2021 to August 2023. Of those who have it, only about one in five have it controlled to below 130/80.
Home monitoring sits in the middle of that gap, and it is handed to people with very little instruction. The cuff arrives in a box, the number appears on a screen, and nobody explains that the size of the cuff can move that number by more than the difference between two categories, or that one reading means almost nothing on its own.

What we cover, and what we do not
We cover
- Measuring: setup, posture, cuff fit
- Recording: what to write down, on paper or a phone
- Averaging: turning a set of readings into one number
- Organising: sessions, days, appointment preparation
- Tracking: what apps do, and what they cannot
We do not
- Diagnose high blood pressure, or anything else
- Recommend, change or comment on medication
- Tell you how to lower your blood pressure
- Replace a clinician who can examine you
- Claim a phone can measure blood pressure without a cuff
Do we test the devices ourselves?
No, and we will not pretend otherwise. We are not a laboratory, we do not put cuffs on volunteers, and we do not time apps with a stopwatch.
What we do instead is check two things for every monitor we recommend, and drop anything that fails either. First, that the exact model number appears on the AMA Validated Device Listing, filtered to home devices — not the brand, not the product family, the number. Second, that the listing we link to reports that same model number in its own specification field.
If you ever see a claim on this site that reads like first-hand testing, that is a mistake and we want to hear about it.
Where the facts come from
Every clinical claim on this site traces to one of these, and each is linked at the point it is used rather than buried here.
Blood pressure categories and what the numbers mean
Understanding Blood Pressure ReadingsAmerican Heart Association. last reviewed 14 August 2025. The 2025 ACC/AHA guideline kept these categories and the 130/80 threshold unchanged from 2017.

How we make money, and what we own
Amazon
We are an Amazon Associate and earn a commission on qualifying purchases made through links on this site, at no extra cost to you. Our tag is bpcentral-20. It changes nothing about which monitors appear: no brand has paid to be listed, no brand has seen a page before publication, and products are dropped when they fail the model-number check regardless of whether they would have earned anything.
BP Central
We make it. It is our own app, so treat what we say about it accordingly. It is free for your first 10 readings and then $6.99 once, with no subscription.
BP Monitor Lab
Also ours, and we say so every time we link to it. It covers the hardware in depth: model-by-model reviews, validation detail, error codes, device compatibility. This site covers what you do with the numbers afterwards. When the hardware question is genuinely the better answer we send you there rather than writing a thinner version of a page that already exists.
If you join the list we hold your address and nothing else about your health. We never ask for a reading. The average calculator and the cuff helper run entirely in your browser and send nothing anywhere.
Tell us if we got something wrong
We would rather be corrected than be wrong quietly. If a number on this site does not match its source, a cuff range has changed, a product is no longer the model we describe, or a link is dead, email support@bptrack.app and say what and where.
Pages carry the date they were last reviewed. When we change a fact rather than a phrase, we change that date.
BP Central keeps a record of readings you enter yourself. It does not measure your blood pressure and it is not medical advice. One reading at home does not diagnose anything. Only a doctor or other health professional can do that.
