Hesley tests the weight and impedance by connecting a Bluetooth body fat scale, and uses algorithms to get the body's various index data, records and saves historical data, and provides you with data management for body management.

Hesley integrates with HealthKit to sync your weight and body metrics data to the Apple HealthKit app. Before using this feature, you will be prompted to authorize and support iPhone 4S and later.
