Keep tabs on your agenda with this stunning calendar app.
Cal's greatest strength is organizing your daily agenda, basically all of the to-dos, meetings, and appointments you have on your plate on one given date. When you launch the app, it automatically jumps to today's agenda, which shows all of your events and Any.do tasks in a chronological list.
The iPhone app inserts "free time" slots between your calendar events. I understand the thinking behind this -- to show you when you have open slots in your schedule -- but it makes the agenda look cluttered and confusing.
You can create a new event in Cal by tapping the plus sign at the top of the screen and entering the event title. Start typing someone's name and Cal will search your phone's contacts. Select someone to invite to your event, and Cal will send out an e-mail invitation. You can also add a location by typing "at" plus the business or location name; Cal will start to search for relevant results.
