the Fitbit mobile app
See the time in units of 10 and 100, not 12/24 and 60!
There are 10 decimal hours in a day, 100 decimal minutes in a decimal hour, and 100 decimal seconds in a decimal minute. Decimal time was the official way to express time in France for a while during the French Revolution.
Decimal calendars have never been standard. This clockface uses 10 days in a decimal week, and 10 decimal weeks in a term. Term 3 is incomplete. This makes it easy to work out the period between dates.
An activity level is also shown. In the spirit of decimalisation, the value is a percentage of your daily goal (or, for heart rate, of your cardio threshold).
Touch the upper 2/3 of the screen to swap to normal time, date and activity units.
Touch the lower 1/3 of the screen to change the activity measure.
You can change settings for colour, time and date formats, and more.
Impress your friends and confuse your enemies! Or start a new revolution: decimal time’s time has come!
