HRM Blue Heart Rate Sensor

Why should you be tied to a device that only lets you use one app and charges you a subscription fee for the privilege?

With an open communication design, the HRM Blue provides unparalleled flexibility with the applications you use. Supported by dozens apps on three different Smartphone platforms and more than 200 ANT+ fitness devices including: Endomondo, Strava, SportsTracker, Runtastic Pro, and more!

Our HRM Blue product is an ultra-light Bluetooth Smart and ANT+ dual cardio sensor weighing only 14g in total.  It is not only dustproof, but waterproof up to a depth of 1.5 meter, so that it can also be used for water sports like rowing, kite-surfing or stand up paddling.

All sports applications that support heart rate measurement using the Bluetooth 4.0 or ANT+ standard should be compatible with our chest strap.

Please be aware that we are not responsible if applications from different vendors are not following the standards.

You can choose a wide variety of apps to meet your sports activities and your optical taste best. Currently, over 100 applications on three different smartphone platforms (iOS, Android and BlackBerry) are compatible.
