Calculator X Free - Advanced Scientific Calculator with Formula Display & Notable Tape App Reviews

This calculator does not give the exact result.

updates it for no adds and the adds continue!!!

Crashed on first use

Best, free little calc I could find. Your can set a custom plain bg (shoot a table top photo or something) for ease of seeing numbers and the paper tape feature (you can see the string of numbers and calcs youre using) is super helpful. You can even email that tape to others. Perfect for lightweight calculations.

This wont even open!!!!

Big annoying ads pop up and are hard to close. They make this app pretty useless.

But in trying to contact them about bugs they make it so I cant ; I already purchased ad free full and it said I did but the adverts retain and even more comes up when non should , and I already own it .. Why does Apple allow this activity , like there endorsing it .. Now the change background changing doesnt work with no way to contact bug reports to have it fixed ; Apple likely still sells it and refuses to hammer down on this issue of selling apps with no support to bug fixes , its not like they dont know how to contact the maker as well as still selling the apps .. And I own the full pro version not the free .. ..

Sin cos does not work. İse iPhone calc Onder utilities by rotating öğüne 90deg and it Will become scientific calc as well.

An amazing calc. Free but advertised..

It loads forever then it crashes

Good luck using this "app", huge ads pop up constantly. Try and change the wallpaper and the calculator flips upside down. Useless trash.

I tried to use this app, and I thought this app would be nice and friendly, but the app is too buggy. I really hate that because once I turned my phone into sideways, the app closed and kick me out. I tried to tap the app so I need to use it, but it turned black. Now, it restarts my phone and I have to wait 5 minutes for the app to start loading. Please fix that! Also, order of operations is what you need to work on! 5+3*2 does not equal to 16! The answer is 11! Oh, you think that since addition come first in the problem, then you add first? Dont you learn that from school? I guess that you werent pay attention when the teachers taught you math. Is that true? If no, then why you dint even know order of operations. Now, I am your teacher. You use PEMDAS as your order of operation. This stand for Please Excuse My Dear Aunt Sally. Or Parentheses, Exponent, Multiplication, Division, Addition, and Subtraction. You do parenthesis first. Then exponent. You either do division or multiplication first if they appear first. You do it before addition and subtraction. No matter if addition or subtraction comes before multiplication or division, you always do them BEFORE addition and subtraction. Again no matter if addition and subtraction comes first, you do one of them in the order from left to right. Do you understand me? If no, then piaaaa

Always crash....

Deleted this in ten seconds. Waste of time.

I had tried Crystal Calc and it didnt work. Then I tried this free version-- and it worked -- but it had ads. It came up with a popup asking if I wanted to upgrade to the version without ads. It verfied my request but it has done NOTHING to take away the ads. This developer is sloppy and doesnt check his/ her work. I hope no one else gives this dev their hard earned money. Run dont walk away from this app and the sloppy developer who takes your money for giving you junk.

It freezes but accept the frozen part its kinda good .

I love this calculator it helps me with my homework all the time and is a great way to solve problems

The paper tape feature is/was pretty cool, until I cleared it for a second calculation. Then it wasnt there and I couldnt get it back!! Now I have a standard basic calculator. What a waste.

I have tried both this and Crystal Calc both by same author and have had no issues at all. It is possible the glitches dont show for some time, but, as I said, no issues. Maybe it has to do with what I-device it runs on. I have iPod. Love the tape, snazzy backdrop, cool little calculator.

Please fix!!!! I paid for NO ads, still have ads. They are only at start up, but if someone pays for an in app upgrade there SHOULD NOT BE ANY ADS! Old review: I have been using this calculator and thought it was nice, so I upgraded to the full no ads. It takes your money and does not take ads away. I even deleted the app and reinstalled and still has ads. *******PLEASE FIX******* Also went to their site, but the link to contact them wont work!? I will change my review if they fix this!
