Calculator for iPad Free is a very good example of what iPad calculator apps should be modeled after. The UI is just plain gorgeous, making it pleasant to use. This app can be used in portrait mode for your basic, run of the mill calculations. Should you need to calculate more complicated math or scientific figures, you can do so in portrait mode. One downside is that it is ad-supported, but I didn't find the ads to be bothersome. There are in-app purchases that will remove the ads if you prefer. If you do choose to pay, you are also provided with more options such as an even larger screen and up to seven different skins. Calculator for iPad Free is definitely worth a spot on your iPad, and an AppAdvice essential choice.
