I first reviewed Amount back in September when the app was iPhone-only and iOS 7 wasn’t out yet. Amount was a simple unit converter that was already compatible with the new OS and that had a nice approach to unit conversions.

Since then, developer Marco Torretta has made the app Universal and added a URL scheme to launch unit conversions from other apps. On the iPad, Amount uses a split-screen layout to organize categories and units. The number pad is a floating widget in the middle of the screen that makes it easy to enter numbers, and, because of the larger screen, you don’t have to tap and swipe as much as on the iPhone. I like it.

Amount strikes a good balance between simplicity and features, and it’s only $0.99 on the App Store.
