Convoto: The Conversion App that Apple Left Out

Apple does a great job with apps in addition to hardware, and several of its "extra" iOS apps are must haves—Keynote and Pages are two examples. But the company should have included a conversion app, either as part of the calculator app or as a standalone one. Fortunately, there is Convoto, an elegant tool for conversions. The interface is nice and clean, clearly inspired by Clear, the to-do app. Rather than garish buttons, a swipe interface is used. Multiple rainbow-colored selections distinguish the numerous conversion options.

More than just a pretty face, Convoto can handle just about any conversion request thrown at it; and it retrieves and stores the latest currency rates when connected, so it can leverage those when the network isn't available. It was reasonable at $2.99 but it is on sale now for $0.99, so this is a good chance to get an "Apple Featured" app at the lowest price possible, in any currency! In fact, here is a list of Unit and Currency Conversion Categories that Convoto can convert:
