Do you ever sit around waiting for a download (or upload) to finish, a video to render, an email to arrive... well wait no more!

Herald will watch for changes or text to appear in a chosen window and alert you so that you can get on with something else. Simply drag the red rectangle over the area that will change (or stop changing, in the case of spinners) and Herald will do the rest.

Download the Herald app on your iPhone to get notified while you're out - why not go for a walk until your tasks needs your attention again! (requires an iCloud account)

And for the developers out there: you can pipe commands into the Herald CLI app and get notified when a certain string is printed to stdout or when the command ends (enabled CLI mode in Herald's preferences).
