Best calculator app I’ve used so far


I’ve tried probably a couple dozen calculator apps over the past few years. There have been 5 or 6 I’ve used extensively to see if they would work for me. I came across Calculator+ a couple of months ago and I can confidently say it’s the best calculator app I’ve used so far.

There are apps out there that offer some more advanced/specific functions and there are some that specialize in fancy features like handwriting recognition. Calculator+ seems to offer pretty much everything I’ve liked about other calculator apps and displays it all in a sensible UI that’s easy to use.

I’m still using the free version since it has 90% of the functionality I need, but I will probably upgrade to the paid version soon to get access to the equation solver, graphing calculator, and handwriting recognition. Really a great calculator app. Give it a try!

Great calculator for iPad


I use to do a long calculation in my physics lab, so far this calculator do the work, and is easy to use. Plus you have the advantage to track what you wrote, and edit if there was a mistake, which help me to save a lot time, especially when I’m tired and start to miss or forget something in the calculation. Also if the answer wasn’t what I was expecting, 🧐 tracking my formulas is a good way to find where is my mistake. Overall I love it, and is my main calculator 👍😁... give a try and you will see the difference compared to others calculator out there.

Best calculator app I have used period :)


Honestly I can't find a better calculator app better than this one. The creators of this app have done a really good job on making this calculator app as best as they possibly can. It literally feels like a real calculator and not a calculator app. If your worried about that don't be because that's a good thing if it feels like a real calculator. The best thing about it is that it's ad free and it has a lot of features and functions that I really like. Keep up the good work and please continue to improve this app more than what it is.

Thank You :)
