Revol-di 1.0 by Kodaski.fr was released 2011 January 20 (55581) and is the third French Republican Calendar app for the iPhone. The name is taken from an early proposal for the first day of the décade, better known as Primidi. Unlike Calendrier and Salut et Fraternité, this one is free. Unfortunately, like the others, it is formatted only for the iPhone (and iPod Touch) and not the iPad. (It's been over a year, why doesn't everybody recognize the iPad?) Also unlike the others, it is targeted at genealogists, so it only converts dates during the revolutionary period when the calendar was in effect, 1792-1805 (JD 2375840-2380688), and does not convert more recent dates, nor does it display decimal time. At least it does not have to worry about which method to use for determining modern dates.
It does have features the others don't, however. For one, you can make notes, which are stored under the (Gregorian) date they are made. This is useful for recording birth dates and such during the Revolution. The entire notepad may then be shared via email. Under "Information", facsimiles of the laws relating to the Republican Calendar are available, in French. (Gregorian dates are also displayed in French.) "Historical context" gives information about the calendar. "The calendar months Illustrations" shows period paintings of calendar girls. There is a "Help" section and four different wallpapers to choose from.
