Description

Clear, light weight, maximum battery saving, and introduced a new metric – MAR:

The value on the bottom left of the clock face is called MAR (weekly Mean Activity Ratio), which is my personal invention. It reflects your physical activity level during the past 7 whole days (from 7 days ago till yesterday). It is recalculated at midnight every day.

----------------------------

MAR = (Cal / BMR - 1) * 100

Where:

Cal is the mean calories burnt per day in the past 7 days (excluding today);

BMR is the user's Basal Metabolic Rate, which is calculated using your weight, height, age and sex.

----------------------------

Some values and corresponding activity levels:

20: Sedentary (little or no exercise, desk job);

38: Lightly active;

55: Moderately active;

72: Very active;

90: Extra active (frequent hard exercise);

110: Extreme;

150: Estimated upper limit in general population (non-athletes) at sea level.

----------------------------

[Version 1.5.0 onward] When tapping on the MAR value, its corresponding level and your BMR value (in calories) will be shown.
