Watchface including calendar of the actual month and smart activity load index recognition for each day.

NOTE: Devices provide activity history only for last 7 days. Older history must be saved into application memory during the time. So you'll get only 7 days history after installation.

Activity load index is calculated from user's BMR, activity class and calories for the particular day.

For men: BMR = 10 x weight (kg) + 6.25 x height (cm) – 5 x age (years) + 5 
For women: BMR = 10 x weight (kg) + 6.25 x height (cm) – 5 x age (years) – 161

eBMR (extended) = BMR x activity_class_coeficient

where activity_class_coeficient has values from 1 to 1.5 based on Activity Class settings in Garmin Connect (Settings - Personal Information).

Indexes are evaluated this way:
1 - green - daily goal reached or daily calories greater than eBRM
2 - blue - daily calories greater than 1.15 x eBRM
3 - blue - daily calories greater than 1.35 x eBRM
4 - blue - daily calories greater than 1.60 x eBRM
5 - blue - daily calories greater than 1.80 x eBRM
6 - red - daily calories greater than 2 x eBRM

Options for 2 custom fields are:
- steps for current day
- distance for current day
- calories for current day
- current heart rate (FR235, FR735XT, Fenix3HR and D2Bravo Titanium)
- goal percentage
- UTC time
- altitude (Fenix or D2 devices)
- week goal percentage (counted from the first day of the week, including today)
- week distance average (without today)
- week steps average (without today)
- week calories average (without today)
- sunrise/sunset
- week progress graph - today is the column in the right (except FR920, Vivoactive and Epix)
