Leave a Review Calculator +
Something’s not right here
Their website is parked so no support is possible via the App Store. The app keeps asking me to purchase an upgrade that I’ve already purchased. The App Store catches this and prevents me from spending anything more on upgrades. To resolve this problem, I uninstalled and then reinstalled the app.
It seems expensive to buy all the features but it’s actually much cheaper than buying a graphing calculator with the software or built-in functions the app advertises. Installation quirks aside, it seems to be a great app.Show lessthreeGHz
A fan for years!
I downloaded this app several years ago, and have been super happy with it, just a big, bold calculator that's easy to use and works perfectly. What else do you want from a calculator?
And now it works with OS9! Just slide the edge toward the center and choose calculator and you can use it while in your checkbook! That is just great! The biggest difference between Windows and Apple is now over.Show lessAllnicknamesaretaken909
Disappointed
I purchased this calculator with the understanding that there would be no more adds. Despite my purchase, I, once again have advertisements at the bottom of the screen. I have attempted to contact the developer several times only to be repeatedly ignored. If you purchase this app now, please note later that eventually your purchase will be voided and adds will once again appear at the bottom of your app screen. To the developer: I will adjust my rating if you remove the adds as I already purchased this app to have them removed.Show lessRicky Rocket22
Stupid
Do you even know what a scientific calculator is???? There isn’t even sin cos or tan on here. The built in Apple calculator is more ‘scientific’ than this. No need to download an additional app.b0xyw0xy
Better than an actual calculator
I’ve been using Calculator+ for a while now and I greatly prefer it over the standard phone calculator AND most physical calculators. It’s simple, easy to use, and everything I need the app for is free! So far it’s gotten me through several calculus, chemistry, and physics classes without a hitch, so I really can’t stress enough how useful it is (y’know, for a calculator app). Keep up the great work! :)Show lessSt3r1ingSi1v3r
The only calculator worth using on iPhone
My app wasn’t working for a couple weeks had to redownload! But I was lost for those few weeks, I tried using the other calculator on the phone and it was just terrible! Also in 12 years with Apple I’ve never once felt compelled in the slightest to write a review until today!Obligated4life
Thankful user
Love this calculator. Clear and easy to use.samwas1
Worked great for years, then...
Then very recently, they or Apple (iOS) made some change that broke it. It would come up in the currency converter and would get stuck when you tried to change it. I reinstalled it twice. After the second time, when I tried to launch it, it would hang on the splash screen (the app icon).
Am trying it again. It was a great app before, so I’m hoping I don’t have to abandon it.Show lessCrocbones
The Bestest!
I have been using your calculator for eons (or at least since you came on the scene), and have looked at others to mix it up (numbers are such exciting things)and you are by far the most user friendly of all the number apps. Thank you for making my life that little bit more manageable. Lovely work you inventive creatures!Show lessSusan Head

I teach secondary school math and I don’t use any other calculator at the moment.greenwolf52
