Heart rate monitor - continuous measurement, graph on the screen of the bracelet.
Definition of activities - walking, running, exercises (squats, push-ups, etc., counts approaches and repetitions), biking (sometimes a scooter is considered there), counting steps up and down (well, almost perfect, sometimes lies)
Garmin Connect (website and app) - excellent analytics and monitoring of health, stress, sleep
A stress indicator with relaxation training (a funny little thing, but several times it helped to sit down and breathe, driving thoughts out of my head)
Alarm clocks - autonomously recorded 5 alarm clocks in the bracelet (before that, there were only 3 pcs in the miband, the rest through the application)
The ability to turn off the bluetooth in the bracelet (sorry, I didn’t see articles in pubmed that exposure to 2.4 GHz benefits the body)
Size, strap - elegant, compact, light and unobtrusive. Put it on and forget it for five days.
