DeciTime - Time for the 21st century

DeciTime stands for "decimal time", i.e. a representation of the time of day based on decimal units.

Since the old times we are used to the somewhat odd counting with 24/60/60 - the time of day has 24 hours of 60 minutes of 60 seconds.

With DeciTime, the day has 10 Dours of 100 Dinutes of 100 Deconds.
Sounds strange, but it is much easier to count in decimal system.

Until now, the day has 86,400 seconds. Now it's 100,000 deconds. A simple math shows that the deconds are slightly faster than seconds. Fast times, fast time ;-)

- 4 nice clock styles
- All colors can be customized
- 6 color sets can be stored
- 'Click' for dours, dinutes or deconds
- portrait or landscape mode
- digital time display as an option

Hurray For the Ten Hour day!!

I’ve been using decimal time for a lot of years now, and think it’s the sure way to go ... on any world. Besides, our 24 hour day only relates to earth, our sun and moon.
This app is a great representation of the 10 hours day. Please keep it updated, unlike the other decimal time apps I’ve used, which gone the way of the dodo, as iOS has updated.

Hope u keep updating it

I really enjoy this app! I'd love to see a 10 hour day normalized. Until then this app makes me feel ahead of the times but perhaps u can add an alarm feature? That would really help me get a better feel for the 100 minute hour
