App Review: MyScript Calculator

Unfortunately my favorite simple calculator, Operations, is no longer available for the iPad. Although, if you’ve downloaded it before it was removed from the App Store, you can still download it by clicking on the “Purchased” tab. Unfortunately, if you haven’t you’re out of luck. However, in my research to find a valid replacement of a free and ad-free simple calculator I stumbled upon MyScript Calculator. All other simple calculators were not ad-free or had to be paid for so this is my next recommendation. It’s different but I actually like how it works. There are no buttons like standard calculator apps. Instead you write your operation with your finger or stylus. MyScript effortlessly translates your handwriting and quickly calculates it right before your eyes.

MyScript supports the basic operations – addition, subtraction, multiplication, and division – as well as exponents, square roots, percentages, absolute values, trigonometry, constants (pi, e, phi…), logarithms, (quantities), and factorials! 😉 I tried to do cubed roots but it wouldn’t register correctly. I even tried raising a number to the 1/3 power to see if that would work but it didn’t. So there are improvements that can be made. Hopefully there will be an update for this. Therefore this is more than a simple calculator and is almost capable of being called a scientific calculator. However, for most calculations this app certainly does the trick.

No Calculator on the iPad?! Best Free Calculator Apps – Updated

I find it odd that the iPad, clearly one of the most revolutionary computing devices in the consumer market, does not even come with a calculator. The iPhone has a simple calculator when held normally but when held in landscape position stretches to reveal more buttons and becomes a scientific calculator. So clearly Apple understands the need for a calculator. Apple also clearly wants iPads to be used in the classroom so it’s mind-boggling that they left the calculator app out.

The iPhone Calculator:

Well, for whatever the reason, there really is no sense in trying to make sense of it all and if and when they ever do make one then it will be welcomed with open arms by everyone I’m sure but until then we’ll just have to sort through the calculator apps in the App Store. So here are my findings for the best free calculator apps. I stress free because there are good free calculator apps and school budgets need not waste money purchasing calculator apps when that money can go towards other more useful educational apps. I also am quick to disregard any apps that have ads in them so even though there are other free calculator apps that are great, possibly even better, when it comes to ads they can be so distracting and something as simple as that can lose the students’ focus on the task at hand so any apps mentioned here are also ad-free =)
