For some people, this is a frequent problem. You're at a pub/bar/restaurant and you can't decide whether it's better to buy pints of beer, or a pitcher. Pint or Pitcher takes the price of the pitcher and calculates what a pint should cost.

eg. the pitcher costs $20.00, a a pint is $7.25. The app shows that is should cost $6.67, so mathematically (depending on how many glasses you will have\share) it is cheaper to order a pitcher.
