Welcome to MoreFit Support

A fitness tracker is not a standalone device. The app is absolutely vital because it is where you make sense of the information the tracker collects and where you can make your personal setting like your stride, height, weight or set your own fitness goal, sleep time and more. Start by using our mobile app 'Da Fit', you will explore more fun and it could be of interest if you're a beginner.

Wear Grace

Placement for all-day wear vs exercise

When you're not exercising, wear Grace a finger's width above your wrist bone.


For optimized heart-rate tracking while exercising:

· Try wearing Grace higher on your wrist during exercise for an improved fit and more accurate heart-rate reading. Many exercises, such as bike riding or weight lifting, cause you to bend your wrist frequently, which can interfere with the heart-rate signal if the watch is lower on your wrist.


· Make sure the watch is in contact with your skin.

· Don't wear your watch too tight, a tight wristband restricts blood flow, potentially affecting the heart-rate signal. The watch should be slightly tighter (snug but not constricting) during exercise.

With high-intensity interval training or other activities where your wrist is moving vigorously and non-rhythmically, the movement may limit the sensor's ability to provide a heart-rate reading. If your watch doesn't show a heart-rate reading, try relaxing your wrist and staying still briefly.
