Meet the Zoom: a fitness tracker that works on land and in water to help you track your various activities. It works around the clock to monitor your heart rate and let you know when you are out of your target heart zone. It is compatible with iOS/Android devices. It supports Google Fit and Apple Health.
Zoom stores your data for up to 7 days. It has a battery life of 5 hours. The device is water resistant to 30 meters. Yet another interesting Kickstarter project.
