CallitADay is an easy, inviting app that helps you create an electronic diary, with text, images, and even audio and video recording.
CallitADay's streamlined interface suits its straightforward purpose: the main, three-part window has a calendar (to start an entry, you select the date you want), a sidebar of previous entries (which you can organize by topic and browse as thumbnails, in a grid or Cover Flow-style), and a large editing pane, with controls for zooming, changing fonts and color, and browsing back through previous entries. This main window also has buttons for quickly creating audio and video recordings (with any attached or built-in microphone or camera). CallitADay lets you drag and drop almost any kind of file into an entry--from pictures and movies to files and folders, which get automatic aliases--and it's easy to resize and move objects. The capability to embed files and folders might even make CallitADay a passable productivity tool for some users, letting you add notes (whether written, audio, or video) alongside what you're working on. CallitADay lets you export your entries to Wordpress and maintain a snippet file.
CallitADay may have a limited feature set, but it also has a low price--and its singleness of purpose makes creating diary entries easy and fun. Users have other choices for journaling apps on the Mac, but CallitADay is one of the most affordable and elegant options.
