When I worked at a family practice, patients would hand me a crumpled notebook full of blood pressure numbers. The right app can do that job better: it keeps every reading in one place and turns them into a simple chart your doctor can read in seconds. Here’s the short answer: the best free blood pressure app depends on what you already own. Apple Health is the easiest free option on iPhone, Omron connect is the best match if you have an Omron cuff, and SmartBP is the most flexible logbook for iPhone.
Here’s what the app can — and can’t — do. An app doesn’t measure your blood pressure by itself. You still need an upper-arm cuff, and the app stores the numbers you take (or the ones the cuff sends over Bluetooth). It also can’t diagnose anything. Only your doctor can tell you what your numbers mean for you.
Best free blood pressure apps at a glance
I compared each app’s App Store or Google Play listing. Prices and ratings are as of October 2026 and can change, so check the listing before you install.
| App | Price | iPhone / Android | Rating (App Store) | Best for |
|---|---|---|---|---|
| Apple Health | Free, built into iPhone | iPhone only | — | Simple logging with no new app |
| Omron connect | Free; optional paid plans for extra reports | Both | 4.7 (103K ratings) | People with an Omron cuff |
| SmartBP | Free; optional paid plans for extra features | iPhone and iPad | 4.5 (about 60K ratings) | Manual logging and PDF reports |
| Withings | Free; optional Withings+ plan | Both | 4.6 (367K ratings) | People with a Withings monitor |
First, get a good cuff and take readings the right way
An app is only as good as the numbers you put in it. The American Heart Association says to pick an upper-arm cuff that fits, because wrist and finger monitors are less reliable. You can check whether a monitor has been tested for accuracy on ValidateBP, a list of validated home monitors.
Before each reading:
- Skip coffee, smoking, and exercise for 30 minutes.
- Sit with your back supported and your feet flat on the floor for five minutes.
- Rest your bare upper arm on a table so the cuff sits at about heart level.
- Take two readings, one minute apart, at about the same time each day, and log them both.
Apple Health: best free option on iPhone
If you have an iPhone, you may not need to install anything. The built-in Health app lets you add blood pressure readings by hand and shows them in a chart over time. Other apps on this list can send their readings to Health too, so it works as your one home base.
- Pros: Free, already on your phone, and your data stays under Apple’s privacy controls.
- Cons: It’s iPhone only, and you have to type each reading yourself unless you pair it with a Bluetooth cuff and its app.
- Price: $0.
To show your numbers to a doctor, follow Apple’s guide on sharing your health data on iPhone.
Omron connect: best if you own an Omron cuff
Omron makes many of the home cuffs sold in U.S. drugstores. Its app connects to compatible Omron monitors over Bluetooth, so your readings arrive in the app on their own. You don’t have to type anything, which helps if you’re not comfortable with small keyboards.
- Pros: Automatic syncing, trend charts, and an option to share readings with your doctor, a caregiver, or family. It can also swap data with Apple Health.
- Cons: Extra features like medication tracking and detailed reports need a paid plan, and the app works best with Omron devices. Check Omron’s compatibility list for your exact model.
- Price: Free to download. The App Store lists optional paid plans, with blood pressure plans starting at $9.99/month.
- Rating: 4.7 stars (103K ratings on the App Store), as of October 2026.
- Privacy: The App Store label says Omron collects health and fitness data, your name, and your email address, and links them to you.
Download Omron connect from the App Store or Google Play.
SmartBP: best logbook for iPhone
SmartBP is a digital version of that crumpled notebook. You type in your systolic (the top number), diastolic (the bottom number), and pulse, and the app builds charts and reports. It can also pair with some Bluetooth monitors.
- Pros: Charts, medication reminders, and reports you can create as a PDF, plus CSV export. It works on iPhone, iPad, and Apple Watch.
- Cons: There’s no Android version, and the App Store lists a long menu of paid plans. Stick with the free version unless you really need more.
- Price: Free with in-app purchases.
- Rating: 4.5 stars (about 60K ratings on the App Store), as of October 2026.
- Privacy: The App Store label says some identifiers and usage data may be used to track you across other apps and websites. Health data is linked to you. A quick word on privacy: if that bothers you, use Apple Health instead.
Download SmartBP from the App Store.
Withings: best if you have a Withings monitor
The Withings app is the companion for Withings devices, including its blood pressure monitors. It’s popular, with the highest number of ratings on this list, and it connects to Apple Health.
- Pros: Clean charts, automatic syncing with Withings devices, and easy sharing with healthcare professionals.
- Cons: It’s built around Withings hardware. The App Store lists a paid Withings+ plan at $9.99/month or $99.99 a year, and the free app is mostly useful if you own a Withings device.
- Price: Free with in-app purchases.
- Rating: 4.6 stars (367K ratings on the App Store), as of October 2026.
- Privacy: The App Store label lists health data, contact info, and precise location, linked to you.
Download Withings from the App Store or Google Play.
What if you have an Android phone?
You have fewer free logbook options than on iPhone, and the best ones depend on your cuff. If you own an Omron or Withings monitor, use that company’s app (both are on Google Play). If you don’t, search Google Play for “blood pressure log,” then open the Data safety section on each listing and skip apps that collect more than they need. A paper log works fine too.
What to share with your doctor
Bring this to your next appointment:
- Two weeks of readings, with the date, time, and both numbers
- Your pulse, if the app records it
- A list of your medications, and when you took them
- Your cuff, so the office can check it against theirs
The AHA suggests having your doctor’s office check a new home monitor, and again once a year. For plain-language background on what the numbers mean, see the National Heart, Lung, and Blood Institute’s page on high blood pressure and MedlinePlus.
Frequently asked questions
Can a phone app measure my blood pressure without a cuff?
No. Apps that claim to read your blood pressure with the phone’s camera or flashlight can’t replace a validated upper-arm cuff. Use the app to log numbers from a real cuff.
Are blood pressure apps really free?
The download is free, and basic logging usually is too. Extra reports, medication tracking, and cloud backup often cost money. Read the in-app purchases list on the store page first.
Is my health data safe in these apps?
It depends on the app. Check the App Privacy label on the App Store or Data safety on Google Play. Apple Health is the most private option on iPhone, since your data stays on your device unless you share it.
How often should I check my blood pressure?
That’s a question for your doctor, because it depends on your health. Many people are asked to take readings at the same time each day for a week or two before a visit.
Bottom line
- Best free option on iPhone: Apple Health.
- Best with an Omron cuff: Omron connect.
- Best logbook for iPhone: SmartBP.
- Best with a Withings monitor: Withings.
Pick the app that matches your cuff, take your readings the same way every time, and bring the log to your next appointment. These apps are tools for keeping track. They don’t replace your doctor. For more health apps, browse our health and fitness app guides and our apps for seniors.
