DO NOT UPGRADE TO PAID VERSION!

There is a bug in the paid version that is not present in the free version.

If you enter The subtotal instead of the total, the tax rate will be zeroed out. This is not a problem with the free version.

I upgraded to get rid of the ads because I kept hitting them accidentally. The lines are really tiny. It turns out you can scroll through the items like subtotal, tax, tip, and total just by repeatedly tapping that section of the screen and dont have to actually tap the specific one you want.

So far as I can tell, the free version calculates perfectly and is a dream to use. Very nicely done.
