As the developer I am biased but I suggest taking a look at Perpenso Calc. It is five calculators in one: scientific, statistics, business, hex and bill/tip. With its support for RPN, fractions, complex numbers and many other features it is comparable to traditional handheld calculators. iPad specific functionality includes customizable display lines.
A related iPhone-only app, Perpenso Calc 4, is a lite app and is upgradable to full via In-App Purchase.
I want to introduce a calculator written by me.
It would be a great calculator if you have children.
Both of them have:
√ Great math practices for your children
√ Tips Calculator (coming soon in iPhone version.)
√ Scientific Calculator
√ Statistic Calculator
But the most important thing is the user interface,
I written this calculator for my daughter for her math homework, (first grade student)
Because it's design for my child, I paid a lot of time to simplify the interface.
You can find the interface is very user friendly to use and do not need to keep too much thing in your mind.
If you are looking for a friendly and smart Calculator, please make a try of this one, thank you~~
