iTunes and the App Store are two of the best online stores for buying digital content like movies and books. They’re also really good at getting you (the customer) to spend money. CheapCharts for iOS is the perfect companion to the App Store and iTunes Store, helping you get apps and digital content at the best price possible.

While I don’t ever mind paying for amazing apps by great developers, who doesn’t like App Store sales — or even better, sales on iTunes movies and music? A few months ago I stumbled on an app called CheapCharts and I’ve been using it ever since to monitor App Store sales on apps I want to keep an eye on.
