OnSale is a thoughtfully designed application that does one thing well: it lets you calculate how much you will pay at the checkout when you are in a shop.

Just enter a price and, optionally, a discount.

It's basically a percentage calculator, with a plus and receipt function.

These are its main features:

+ Two screens for entering both the price and the discount quickly.

+ Tax support (turn it on in settings).

+ Sum the result of several calculations and show the total in a beautiful receipt (PLUS PACK only).
