In preparing this year’s 20 Under $20 list, we loved the idea of presenting 20 killer Mac apps you might not know about — 20 is such a round, pleasant number, and would hopefully let us find something for everyone. But $20 per app might not seem like the bargain-basement price that it used to, even just back in the summer of 2011 when we did our last 20 Under $20 feature.
But guess what? Most of these polished, stable, user-friendly, and utterly useful applications don’t come anywhere close to a full Andrew Jackson, anyway. Four of them are free, and only two cost over $10. We thought about calling it “18 Mac Apps Under $10 and Also Two That Are More Than $10 But Still Less Than $20, and By the Way, Four Are Free,” but that’s just too long, wouldn’t you agree
A picture is worth a thousand words, but why limit yourself to just one picture? Diptic lets you create square-formatted collages of up to six photos. This is a port from iOS (the universal iPhone/iPad app is also $0.99), and it’s just as easy to use here, with Multi-Touch trackpad gestures and easy-to-understand options and sliders. All the frames are adjustable, and you can drag in photos from the Finder, iPhoto, or Aperture, or access those libraries through the Open File dialog. (Scroll all the way down and click Media at the very bottom of the sidebar to see your iPhoto and Aperture albums and events—the Media browser is a little hidden.)
