Another week is almost gone, hundreds of applications for iPhone and iPad were added to the App Store and once again I’m in the difficult position to pick the ‘Application of the Week’.

I usually tend to pick a game but this week one application in the Travel section caught my attention and I’m now recommending it to you all.

Ever wondered when you are about to take a journey if it would be cheaper to fly or to drive? Well, I do…all the time.

Cost2Drive will help you calculate the cost of driving anywhere in the US taking into consideration the car you drive (20,000 vehicles included), the current gas price, and it gives you the ability to add your own vehicle (RV, motorbike, skateboard etc) and more.

Once you have your road trip cost figured out, the Cost2Drive app will look on the very popular KAYAK website for a flight to the same destination and display the cheapest available airfares in one sleek and easy to use interface.

Great app, available from the App Store for $1.99
