The Litmus Garmin Bridge app is how you will sync your Garmin vivosmart 4 to your iPhone for your clinical study or trial. This app will ensure the information collected by your Garmin device (heart rate, steps, sleep, etc.) is properly received by study managers.
Make sure you have your subject ID and Garmin device on-hand when you download this app (Subject ID is printed on a sticker on the box your Garmin came in).
Please refer to the directions in your Getting Started Guide after downloading this app.
