What is the Computer preview version?

The Smartphone calcs are for small smartphone screens.
If you view them on a computer or laptop screen they become too wide and too big.

With the Computer preview versions (below) you can see them on your computer without that stretching issue. All of the calcs in the preview are fully functional.

Have a look and see what you think. Your QuickCalc license lets you use any of the tools in any format you like - on your PC, on your smartphone, or both.
