Simple, fast, good looking

This app is a perfect quick converter that is a pleasure to use.

Exactly what I was looking for!

My only suggestion would be an option to click one of the numbers and be able to manually type a number since sometimes it may be quicker to do that than scroll. Otherwise this app is perfect
