If you’ve ever wondered what the difference between a clove hitch and a half hitch is, or if you spend more time undoing your knots than tying them, Grog’s $5 Animated Knots gives you a full rundown of many popular ligatures used in everything from fishing to bushcraft.

At $15, Blogo ( Mac App Store Link) may look expensive for a blogging tool, but this app has the features to justify its price.

Quote-Unquote’s $30 Highland ( Mac App Store Link) won’t turn you into a professional screenwriter, but it will let you focus on getting the first draft of your play out the door.

The Finder is a powerful tool, but there are times when you need a little extra help to sift through the reams of files that populate your hard drive—and that’s when Cocoatech’s $40 Path Finder 7 comes into play.
The app helps you collect and collate all your important documents, and comes with a number of powerful tools that handle batch operations like copying, renaming, and selection based on advanced criteria.

Everyone’s favorite compression utility is still alive and well, with version 16 of SmithMicro’s ever-so-popular StuffIt Deluxe hitting the shelves this week.
