Calculations Made Easy

This app is all about making your life easier. You can perform all kinds of calculations on this app and even switch between two themes. If you choose to purchase the full version of this app you'll actually get more themes, settings, scientific notation, engineering, and a paper.

Best iphone and ipad apps

The full version also supports binary, octal, and hexadecimal calculations. There is a number of in-app purchases available ranging from $0.99 to the $9.99 offering which is the Complete Pack. If you plan on using the app often it would probably be well worth the upgrade.

As far as the free version goes it was making users quite happy until the upgrade a couple of months ago which results in its customer rating dropping quite a bit.

There were quite a lot of updates and changes that were made to each of the packages, including the free one, and it seems as though users were happier before these updates.

Using the App

While calculator apps may all seem identical I do find there are some differences between them and for me I really like the feel and look of this one.

You are given quite a few customization options with the free version such as the two themes, the ability to change the sounds or turn them off, the ability to turn on/off RPN mode, and even the look of the actual numbers on the display. I wasn’t really expecting that many options in the free version.

I also like how fluid the app feels. The keys respond very well to touch. Turn your device to landscape mode and you’ll see even more keys show up with additional features.

In this mode it feels full-featured and complete. I can see this being a great tool for students in particular so there is no need to carry around a separate bulky calculator.
