Customer Reviews

My "Go To" Calculator

I don't usually write reviews, but I think I should because of the hard work that you guys have done in making this app an excellent one. I have always used this app but since the update... it has gone to another level. Very very top-notch work. The only thing I think is needed for perfection is iCloud support.

Wouldn't it be great if all your calculations on the tape from one device could automatically be synced to the other through iCloud? I know you guys are thinking of it. I am. I use your app every single day on multiple devices. Implement that capability in and you guys will be the greatest ever.

Best App, Easiest App, I Have Ever Used.

This App was great and easy to use before the update, I did not think it could get any better. Then along came this version update, Lo and behold, They just out did them selfs, It has become even better than it was. If that is not great, I do not not know what is. I personally Have not been able to find any flaws in it. But it would be PERFECT "In my opinion only" If they could extend the decimal points past 12 digits, to Something Around 24. Wonderful Job. Keep Up the Great Work. One Happy and Satisfied customer.

Best Calculator on the Market

This calculate is well designed. It makes doing everything for the simplest to the most complex calculations clear and effective. The running total and list of items in addition and subtraction alone make it worthwhile. I can check for typos during a calculation and easily revise for correct results. I use this instead of any other calculator apps out there. I replaced my Apple calculator on my main page. Get this one!
