This one is for big arms

  • Pros: Large upper-arm circumference is not a problem
  • Cons: Pricier than other models on this list and no smartphone connectivity

Some folks just need a bigger cuff to take a more accurate reading. And for those people, the LifeSource is the best choice. Able to accommodate a 16.5- to 23.6-inch arm circumference, you should be able to measure the blood pressure on a professional bodybuilder, no problem.

Omron Evolve

All the technical bells and whistles, for just about everyone

best-blood-pressure-monitor-omron-evolve-review.jpg
  • Pros: Sophisticated smartphone app, support for two user profiles, integration with Alexa and AliveCor Kardia, and attractive all-in-one design
  • Cons: Cuff may not accommodate larger arms, the device may be too complicated for elderly use, and the display is small

Omron's Evolve looks like something you might even see on a futuristic sci-fi show, like Star Trek. And it wouldn't be out of place there, because not only does it work with Omron's smartphone application, which can track two users' blood pressure histories over time, but it also integrates with Alexa as well as the AliveCor Kardia cloud service, so you can track blood pressure and mobile ECG readings from the same app.

Omron Platinum

The Cadillac of blood pressure monitors

best-blood-pressure-monitor-omron-platinum-review.jpg
  • Pros: This one does pretty much everything and is the best all-around unit on our list
  • Cons: None that we can think of

The Omron Platinum does everything the Evolve does, but it allows for more than two users and has more of a clinical-style, detached upper arm cuff rather than an all-integrated cuff unit. It comes with an AC adapter, so you don't have to worry about charging it. A high morning average indicator alerts the user if systolic or diastolic measurements are out of the normal range in the morning when there is a higher risk for heart attack or stroke.

Buying considerations

Our above list of products is vetted and should fit all budgets and usage scenarios. When considering a blood pressure monitor to buy, you should look for features such as:

  • Smartphone connectivity
  • All-in-one, upper-arm style designs
  • Units with large displays for elderly or vision-impaired patients
  • Clinical-style multi-piece configurations for ease of use
  • Units with large cuff accommodation
  • Devices with remote clinician monitoring capabilities if needed

Our least expensive device on the list is under $50 and features a large backlit display. There are certainly units on the market that are cheaper than $45, such as the more entry-level units in Omron's product portfolio, but you then start sacrificing features such as display size, backlight, blood pressure history tracking, upper-arm cuff configurations, multiuser, and even basic app connectivity.
