Day One is a beautifully designed personal journal. The app is designed to help you log your daily activities, meetings and more and keep everything in sync with your iOS devices via Dropbox or iCloud. The Retina-optimized Day One has a handy calendar view that lets you keep track of what you did on a given day at a glance. Having trouble getting inspired? You can set a reminder so that the app prods you to update your journal. We especially like the Menu Bar Quick Entry feature, which lets you start writing without opening the app.
