Unit converting apps are an interesting breed in the iOS App Store. While most app categories contain a few real gems buried beneath a mountain of garbage, well-designed unit converter apps are much easier to come by. We recently covered one example here on BGR, and now we have another to share that has just been made available for free for a limited time. Convertizo 2 by Perfect Dimension is a great looking iPhone app that fits perfectly with the iOS 7 interface and lets users convert just about anything they can think of. Currency, weight, volume, distance, temperature… it’s all covered. Don’t believe us? Here are the categories listed in the app’s description: • Angle – Degrees, Gradians, Mils, Radians.
