Measurements aren’t really meant to be made by human beings. Measurements are a job best left to to robots and Convertbot is here to serve.

I first saw this app on a list of 30 sexy iPhone apps, and by golly, they were right: Convertbot is ridiculously good-looking. It features a hi-tech sounding interface complete with smooth metal sound effects and a polished metal appearance. Every UI element glides into place, and panels will just slide open or closed when needed. The Batmobile wishes it had this many moving parts.

Convertbot works by using the dial to selecting a conversion category (weights, currency, temperature, etc.) and then selecting the specific measurements you’d like to convert to and from. Then you simply tap on the “From” field at the top of the screen, enter a number, and watch as the “To” field instantly changes with the correct converted value. I

One thing that can be a bit confusing is that the app is basically navigated purely via the icons — and it can take a little while to register what they are, or where they’re placed on the dial. Otherwise, I’ve found Convertbot to be a fantastic example of a gorgeous and functional UI. A big kudos to Tapbots for making something like a converter a fun app to use!
