absolutely fantastic app. I use it extensively at work and it's invaluable. very well laid out, easy to convert from one thing to another. if you're in the telecommunications or RF field, this is definitely an app you need to have in your arsenal.

Love the app but it refuses to appear either in my app drawer or as an icon on my home screen.
