Heart Rate Monitors

Chest Strap

Best for tracking workouts, monitoring real-time heart rate, HRV, workout duration, caloric expenditure as well as heart rate progression by exercise zone.

How to wear It

Attach the heart rate sensor to the chest strap, marked ‘L’ towards Left, ‘R’ towards right. Adjust the length of the chest strap so that it can be fastened tightly but comfortably to your body. Be sure that the electrode areas are firmly against your skin and the sensor is in central position.

The device will automatically detect your heart rate and when it does, it will beep twice and the circle will blink green.

Iron Cowboy

James Lawrence, Guinness World Record holder. Biostrap’s ability to remotely monitor my health from anywhere is a huge piece of the puzzle in giving us a chance at accomplishing what we believe may be endurance sports history.”

Andre Obradovic

Endurance Athlete & Health Coach "I do about 6 Half Ironmans a year and Biostrap is a fundamental tool in my training system to make sure I'm performing at my best."

Dr. Daniel Gartenberg

CEO at SleepSpace "What's really interesting to me about Biostrap, is that this is one of the first wearables that's getting high-resolution heart rate data."

John Porterfield

Scientist “I have sleep apnea, and I use the CPAP machine. I’m one of the lucky people who’s been diagnosed and can tolerate that. And, so I also put on my Biostrap device, and I can see the moments when I’m having trouble breathing.”

Ashley Grimmel

Health Coach "I really found that with Biostrap's data, I can feel confident that this [seeing my clients' health] is an issue, and when we look more into it and follow that up with lab testing, usually there's something there. It's almost like a smoke signal before there's a fire."

Pairing with the Biostrap App

Make sure to have the heart rate monitor on while pairing it with your phone. If you aren’t wearing the heart rate monitor, it will be in sleep mode and the Biostrap app will not find it
Go to Settings at the bottom right of the main app dashboard
Select “Add device”
Follow the instructions on the screen and wait until the app locates your HRM and pairing is successful
As it pairs, the blue light will start to flash. You’ll hear the chest strap beep twice again indicating that pairing was successful
Once your heart rate monitor is paired, on the main dashboard, you’ll see your active heart rate and active heart rate variability displayed and you’re ready to track your workout
If you are having difficulty pairing, please wet the inside of the chest strap to improve the conductivity
