From Tilted Entertainment:
The fastest way to convert Yard to Meter, and the other way around. "Apps that can convert all the units you can think of are slow to use most of the time. The solution would be to have an app that does exactly what you want." This is exactly what YardToMeter does. Just open the app and start typing numbers. That's all. The App will convert the number you typed in to both yards and meters 'on-the-fly'. There is no need to specify what unit you want to convert, just tap the number in and read the results straight away. With the integrated calculator it is possible to do simple calculations right within the App! Check out our other apps to convert more units just as fast: http://itunes.com/apps/haviking
