Swimming App Professional

The Swimming App Professional, running on most Connect IQ™-compatible Garmin devices, supports you in improving your swimming performance by tracking the most important parameters like distance, speed, pace and time with high sensitivity GPS. Additionally ANT+™ compatible sensors for heart rate and temperature monitoring are supported. 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
