Very Disappointing and Expensive

UPDATE: After viewing a while, the Roman clock is totally whacked. There appears to be no rhyme or reason to the time displayed.
ORIGINAL: This seems to be based on the civil clock. I was really hoping the 12-hour option would have the hōra prīma stating at daybreak and nox beginning at sunset. Not that I know all that much about it, per se, but enough to be disappointed. The calendar dates seem, so far, to be spot on, but I could have figured that out myself. The clock is the harder part. This is not worth the price at all. NOTE: It’s also unsupported.

This is a fun clock!

It’s cool and works great

Creative way to show time

This is a fun way of displaying time. I have found that the app is good way to force myself to practice Roman Numerals if I want to know the current time.

There are also some nice little additions to the clock that have made me learn a few new things, such as what the word "Kalends" means (the first day of the month on the ancient Roman Calendar)

Showed it to a friend who is trying to teach Roman Numerals to her daughter and she was pretty excited by this.

This is a great app

I've never concentrated on reading Roman numerals as hard as I do with this app. I'm especially enjoying explaining to my 7 year old why IX isn't written as VIIII.
I recommend this to anyone who hasn't forgiven the Caesars for allowing the barbarians to become citizens...

Praesignis

Possibly the finest Latin language clock currently available
