Jiffies

Jiffies is an event-clock that lets you see immediately all upcoming events and how they are distributed over the day.

It draws two circles for the 24 hours of the day: an inner circle which is ranging from midnight to noon, and an outer circle continuing the interior until the end of the day. On these two circles, all events of a day are shown in their calendar colors in the form of circular segments. Jiffies shows you at a glance when you have appointments and where there is still room for new events.

The app synchronizes automatically with your calendars, including iCloud and other subscribed calendars.
