Mac/iOS: Previously mentioned Sparkbox — an app that stores and organises anything you find inspiring, like a private Pinterest — is available at a large discount today. The Mac app drops from $20.99 to $6.49, and the iPhone app from $5.49 to $1.99.
When I first reviewed Sparkbox, I really liked it because it provided a solid, free alternative to its competition on the Mac. Shortly after the review, Sparkbox started charging $20. While it serves as a handy tool for cataloguing images and other inspiring things you find on the web (or on your computer, for that matter), we found it overpriced. Now you can pick it up — today only — for the much more reasonable price of $6.49. You can also find its iOS counterpart for $1.99 if you want that as well.
