If you find your calendar app on iOS a little boring then check out Any.Do's CAL app. Using an elegant and clean interface that's reminiscent of Google Now's Cards, schedules, events and appointments come to life . Replete with intuitive touches, CAL doesn't just remind you it's someone's birthday, it also offers various options on how to contact and greet them complete with their photo. Currently free on the iOS App store, CAL is coming to Android sometime soon.
