HedgeHog today announces CircleTime 2.0, their new round calendar app for iOS devices. With its round structure, CircleTime enables a time display of limitless possibilities. It also represents a new way of understanding time. The calendar is in the form of a rotating circle that, as a clock, moves through time, showing a day, month and year. It simultaneously shows the length of daylight for each day in a year for every town in the world, thus enabling an optimal use of your time. CircleTime 2.0 is $2.99 and can be downloaded from iTunes.
