TrackFit

TrackFit connects your iOS device to a Bluetooth-enabled body fat scale via Bluetooth 4.0, allowing you to view physical health indicators (eg, weight, BMI, muscle, water, protein, visceral fat, bone mass, etc.) through the app.

TrackFit integrates HealthKit to sync your fitness results to the Apple HealthKit app. Before using this feature, you will be prompted to authorize and support iPhone 4S and above.
