Does anyone know of a simple calculator that has a Tax button and memory. I need to be able to add 20% VAT to calculations using just 1 button then add the result to the memory.

I have found an app which should do what I want but can't download it from market. Probably because of the screen res of my wildfire. Can someone post the apk file so I can at least try and see if the app works on my phone. It is called Sales Tax/Vat Calculator Free and the link to it is below.
