OneView Calendar is a new innovative calendar app for IPhone, IPad, Android, Windows Phone, and for the web. You can use it alongside or instead of your standard calendar. The idea behind OneView Calendar is to present a simpler and more intuitive way of viewing your calendar. It doesn't have a day view, week view, month view or an agenda view instead it replaces all of these views with one single view that is zoomable and scrollable. This turns out to be a much easier way for most of us to grasp what is going on.
