As many people are concerned about watch faces,No.1 F4 colorful has 3 pre-installed dials direct in watch .You can find various options in profile tab within app Hplus.
What I need to point out about No.1 DT58 is HRV monitor(Heart rate variability).HRV is the physiological phenomenon of variation in the time interval between heart beats. It is measured by variation in the beat-to-beat interval.If the intervals between your heartbeats are rather constant,your HRV is low.If their length varies ,your HRV is high. HRV can be traced back to our autonomic nervous system. HRV indicates the state of your health and fitness, recovery and readiness, how you feel about ordinary life.You can test ECG and HRV now on your wrist.It gives you insight about heart,prevent you from heart disease and diabetes.Another feature is respiratory guidance.You need to exhale and inhale for 2 mins to calm down.Many people are stressed out these days, doing exercises,calm down and find your inner peace for a moment.
