This kind of journal doesn't require a notebook and pen. Instead, Day One Journal Diary is an app for iOS and Mac OS X devices that easily records important details. Created by app developer Bloom Built, Day One will allow users to type in their memories, ideas, events and save photos. Executives will be able to record ideas and details of business meetings. With Day One, add current locations, use photo and date/time when adding an entry and tell the weather. It has a photo resolution up to 2,100 pixels. What's great about this app is that it can back up to iCloud or Dropbox so entries can be recovered if the phone is lost or damaged. With the latest update, this app also can support PDF export and printing. Originally $4.99, for Apple's fifth anniversary this app is on sale for, well, absolutely no cost.
