Methodology
How we review — accuracy first
A blood pressure monitor has one job: give you a number you can trust. So that’s where our review starts, before comfort, features or price.
1. We start with independent validation
Any monitor can claim to be accurate. We only trust independent validation registries — programmes that test a specific model against a recognised accuracy standard (ISO 81060-2) and publish the result:
- validatebp.org — the US Validated Device Listing, run by the American Medical Association through its Target:BP initiative. An independent physician committee reviews each device, and the AMA takes no manufacturer funding for the listing. This is the primary US badge.
- STRIDE BP — a global list from the European, International and World Hypertension societies. It’s our international corroborator, and it sometimes lists models that haven’t been submitted to the US programme.
For every monitor we state which registry lists it. If a model is on STRIDE but not the US list, we say so plainly and don’t imply an AMA badge it doesn’t have. If we can’t confirm a listing, we don’t call it validated.
2. We weight the score toward what matters
Our overall 0–10 score is a weighted blend of six signals:
| Signal | Weight | Why |
|---|---|---|
| Reading accuracy | 34% | Independent validation status is the single biggest factor — a monitor that isn’t accurate is worthless. |
| Ease of use | 20% | A monitor you find fiddly is a monitor you won’t use consistently. |
| Display readability | 16% | Numbers you can read without glasses matter — especially for our older readers. |
| Cuff & comfort | 14% | The wrong cuff size reads falsely high; a comfortable, well-ranged cuff is part of accuracy. |
| Value | 10% | What you get for the money — accuracy shouldn’t require overspending. |
| App & syncing | 6% | Apps help some people and annoy others; we weight it lightly and judge it on delivery. |
3. We’re honest about our evidence
Every review carries an “evidence used” label so you know how we know:
- Hands-on tested — we used the unit ourselves and logged readings against a validated reference.
- Community-verified — built from specs plus a large body of verified-buyer reports, cross-checked for consistency.
- Spec + validation based — built from manufacturer specifications and registry status; not yet hands-on.
We will never label a monitor “hands-on” that we haven’t physically used, and we don’t invent test numbers.
4. What we don’t do
We review devices, not people. We don’t tell you what your blood pressure should be, how to read your results, or what to do about them. Those are questions for your doctor. This keeps us firmly in product-review territory — and keeps you safe.
5. How we make money — and why it doesn’t bend the rankings
Some links earn us a commission if you buy. That never changes a score or a rank: the ranking is set by the method above before any commercial consideration, and our budget picks routinely outrank pricier models. See our full disclosure.
