Iquark running, also known as iquark international, is an app that can track your run and help you achieve your running goals. Iquark provides the detection of heart rate and sleep. Whether your goal is to win 5K, refresh marathon personal record, sleep quality or heart rate health, it will help you to be prepared and better put into life. When the device is connected to the app, it will push the sports data to apple health.

- because the running function requires GPS to help users understand the distance, duration and other related parameters
- if you use the GPS function for a long time, your battery life may be reduced
