Great calculator!!!

The calculator on my I-Phone is the best and most user friendly. It must just seem like you to me, but it always has the answers for me before I have finished entering the data. GREAT GOING and CONGRATULATIONS for making such a great I-Phone!!!!!

It’s ok I guess

Ok so the only problem that I have with this is that we have to pay to use the fraction section. That is what I don’t like. Say that you are a student and you forgot to bring your calculator home from school and you need a calculator that does fractions, and the only option that you have is to purchase one on your phone but your mom says that if she has to pay for it then she won’t let you get it. Well, since I didn’t have to pay for it to purchase it she let me get it, but the fact that I have to pay for it to use the only thing that I purchased it for is dumb. Other than that, I think that it’s really clear and a good app for fractions and other math if you want to pay. This calculator app deserves three stars, that’s it. If you would like me to give you five stars, then make the whole entire app free, not just some of it.

Hello! Thanks for your feedback.

I would give it a 0 if I could

This app is a rip off. It shows things that if it will not give you unless you pay the stupid people money and it never said you had to in the App Store so these people should learn how to advertise the truth before scamming the innocent person. I am a 12 year old girl trying to do but can’t because the stupid people wanna put all of the things that are advertised in the actual app and I have no money to get them.

Developer Response ,

Hello! All our Apps have a free version and a premium version. You can use the basic features of the App for free. Hope that you reconsider our App!
