Cardio App Professional

The Cardio App Professional, running on several Connect IQ™-compatible Garmin devices, supports you in strengthen your heart muscle by tracking the most important parameters like distance, speed, pace and time with high sensitivity GPS. Additionally ANT+™ compatible sensors for heart rate and foot pod are supported. Especially the internal or ANT+™ heart rate sensor can be used to obtain important heart rate-related info like current, minimum and maximum heart rate, current heart rate zone, current percentage of the maximum heart rate and much more. It is designed as a watch app (and not a data field) for following reasons:

Simple to install and use
Arbitrary feature enhancement possible
Circumvent that some watches (e.g. vivoactive™) can only display two Connect IQ™ data fields
