Blood pressure apps, honestly

No app measures your blood pressure. Not from your fingertip, not from the camera, not from your watch. Measuring blood pressure means squeezing an artery with a cuff and detecting when the flow changes, and a phone has nothing to squeeze with.

What a blood pressure app is genuinely good at is the part that comes after the cuff: keeping every reading, working out the averages, and turning months of numbers into something you can hand to a doctor. That is worth having. It is just a different job from the one the App Store screenshots imply. Reviewed 29 August 2026.

Why phone-only readings do not work

This is not our opinion, and it is worth reading the sources rather than taking ours.

American Heart Association

Cuffless devices such as smartwatches, rings, patches and fingertip monitors are not yet proven accurate enough to diagnose high blood pressure or to guide treatment. The 2025 AHA/ACC High Blood Pressure Guideline recommends against using them for diagnosis or treatment.

Cuffless Devices for the Measurement of Blood Pressure: A Scientific Statement, Hypertension, 2026

Harvard Health Publishing

Reporting on a JAMA Internal Medicine study of the Instant Blood Pressure app, which found that more than three quarters of people with high blood pressure using it were falsely reassured their blood pressure was normal. Its advice is not to use any app that measures blood pressure with the phone itself.

Don’t trust this smartphone app to measure your blood pressure

The failure mode is the dangerous direction. An app that reads low tells someone with high blood pressure that they are fine, and they stop looking. That is the finding in the JAMA study: most people with high blood pressure using that app were told their numbers were normal.

Three different things are called a blood pressure app

They sit next to each other in search results and they do not do the same job.

Do not use these

Apps that claim to measure your blood pressure

You put a finger on the camera, or hold the phone to your chest, and it shows you a number. There is no cuff anywhere in that description, and pressure is what a cuff measures. These are the apps the research below is about.

Fine, if you bought that cuff

Companion apps that come with a cuff

Omron Connect, Withings Health Mate, Beurer HealthCoach. A real monitor takes the reading and sends it over Bluetooth. The app is a place for the numbers to land. Each one only works with its own brand of monitor, which is the catch.

Works with any monitor

Loggers you type into yourself

You read the number off the monitor screen and type it in. Nothing pairs and nothing syncs. That sounds like more work, and it is about eight seconds of it. In exchange the app works with the monitor you already own, including one with no Bluetooth at all.

A companion app ties you to one brand of cuff

This is the part nobody mentions when you buy the monitor. Omron Connect works with Omron monitors. Withings Health Mate works with Withings. Beurer HealthCoach works with Beurer. They are not competing apps you choose between. Each one is the software half of a specific piece of hardware.

That matters in three ordinary situations. Your monitor breaks and you replace it with a different brand. A second person in the house gets their own monitor. Or you have three years of history in one app and the company changes the terms. In each case the readings and the app are joined at the hip, and moving is a manual export at best.

Typing the numbers in yourself avoids all of it. It costs about eight seconds a reading. In exchange the log is yours, it works with whatever monitor you own now, and it keeps working with whatever you own next. That is the real trade: a little friction for no lock-in.

We are not going to compare those three apps feature by feature here. Our sister property does it properly, brand by brand, and duplicating it would make both pages worse.

What about Apple Health and Health Connect?

Both come with your phone and both can hold blood pressure. They are not the same kind of thing, and the difference decides whether you can use one on its own.

Apple Health, on iPhone

You can type readings in by hand: Health, then Browse, then Heart, then Blood Pressure, then Add Data. No monitor and no other app required. It holds the two numbers and the date.

What it does not do is anything with them. No averaging across a week, and no summary to hand over.

Health Connect, on Android

This one is commonly misdescribed. Health Connect is a storage and permissions layer, not an app you open and type into. Google’s own documentation describes it as something that “stores and structures health and fitness data” for other apps to read and write.

It supports blood pressure as a data type, so an app can put readings there. You still need that app. Health Connect on its own is not somewhere you can keep a log.

If a free place to put the numbers is all you want and you have an iPhone, Apple Health is a perfectly reasonable answer and we are not going to pretend otherwise.

Five privacy questions worth asking

Your blood pressure history is health information about you. We are not going to make claims about what any particular app does with it, because we have not audited them. These are the questions to put to whichever one you pick, including ours.

  1. Does it make you create an account?An account means the readings are tied to an identity somewhere. Some apps need one. Many do not.
  2. Where do the readings actually live?On the phone, on a server, or both. "Cloud backup" is a server.
  3. Can you get your data out?If there is no export, the history is hostage to the app staying installed and the company staying in business.
  4. What happens when you delete the app?On the phone only means gone. On a server means you have to ask.
  5. Is anything shared, and with whom?Read the privacy policy for the words "third party", "analytics" and "advertising". This is the question an app store label answers badly.

For what it is worth on this site: this page has no idea what your blood pressure is, and neither does our average calculator, which does its arithmetic in your browser and sends nothing anywhere.

Two people, one monitor

Very common, and it goes wrong quietly. A monitor with one memory bank mixes two people’s readings into one list, and the averages it shows afterwards belong to nobody. You often cannot tell by looking, because every number is plausible.

Three ways out, and they are not equally good.

  • A monitor with separate user slots. Two banks, one button to switch. The catch is remembering to press it, every time, before the cuff inflates.
  • A guest or single-reading mode. Keeps the second person out of the first person’s memory, but does not give the second person a history of their own.
  • Log separately, on paper or in an app. The monitor stops being the record. Whoever measured writes it in their own log, and the shared hardware stops mattering.

The third is the one that keeps working. Whatever you choose, the important part is that each person’s readings end up somewhere that is only theirs, because an average across two people is not a number about either of them. And if you are sharing a monitor, check the cuff fits both arms.

Check the cuff fits both of you

Paper against an app, honestly

We make an app, so read this knowing that. We also give the printable away free and have no intention of stopping, because for a lot of people it is the right answer.

Paper loses on exactly two rows, and they are the two that start to matter after the first month: working out the averages, and still having in June the readings you took in February.

Whichever app you pick, the monitor is the part that matters

Every app on this page depends on a number that came from a cuff. If that number is wrong, a beautiful chart of it is still wrong. Two things decide whether it is right: whether the exact model passed an independent accuracy test, and whether the cuff fits your arm.

Where BP Central fits

We make one, so treat this section as what it is. BP Central is the third kind: a logger you type into. It works with any monitor because it never talks to one.

What it does

  • Fast entry
  • Your whole history
  • Trends you can tap
  • Averages that update
  • What the numbers mean
  • A summary you can send

What it does not

  • BP Central does not measure your blood pressure. You need a monitor. You type in what it shows.
  • There is no PDF or spreadsheet export. The summary goes out as plain text through your phone share button.
  • It does not connect to Apple Health, and it does not pair with a cuff.
  • There are no reminders and no notifications.
  • Readings are tied to your install, not to an account. If you delete the app or lose the phone, they may not come back.

BP Central does not pretend your phone can measure blood pressure. It does the part a phone is genuinely good at: recording your cuff readings, averaging them, showing the trend, and handing you a summary.

Common questions

Can an app measure my blood pressure without a cuff?

No. Blood pressure is the pressure inside an artery, and measuring it means pushing back against that pressure with a cuff and detecting when the flow changes. A phone camera and a fingertip cannot do that. The American Heart Association looked at cuffless devices in a 2026 scientific statement and found they are not yet accurate enough to diagnose high blood pressure or guide treatment, and the 2025 AHA and ACC guideline recommends against using them for either.

What is the best blood pressure app?

It depends on your monitor. If your monitor has Bluetooth, its own companion app is the least work because readings arrive on their own. If your monitor has no Bluetooth, or you would rather not run the manufacturer app, a logger you type into works with any monitor. What matters more than the app is that the monitor itself is a validated model with a cuff that fits your arm.

Are free blood pressure apps any good?

Some are. On iPhone, Apple Health lets you type readings in by hand at no cost and export them. On Android it works differently: Health Connect stores blood pressure for other apps to write, so it is not somewhere you can sit and type a log yourself. You still need an app. Either way these are general health stores rather than blood pressure tools, so they hold the numbers without doing much with them. Paid loggers usually add averages, trends and a summary you can hand over. Free is a fine place to start.

Do I need an app to track my blood pressure?

No. A paper log with the date, the time, both numbers and your pulse is exactly what most clinics ask for, and many hand out the chart themselves. An app helps with the parts paper is bad at: working out averages over weeks, keeping a history that does not get lost, and producing a summary without you doing the maths.

Does a blood pressure app make my monitor more accurate?

No. Accuracy comes from the monitor, the cuff size and whether that exact model passed a validation test. Nothing about a phone being nearby changes any of those. An app changes whether your readings survive long enough to be useful.

Will an app tell me if my blood pressure is dangerous?

Do not rely on one to. An app can show you which range a reading falls in on a published chart, which is a lookup. It cannot examine you and it does not know your history. If a reading is very high and you feel unwell, that is a medical question and it is urgent.

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.
