ads , and it stinks

Ptsgroup

Deleted this in ten seconds. Waste of time.

I had tried Crystal Calc and it didn't 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 doesn't check his/ her work. I hope no one else gives this dev their hard earned money. Run don't walk away from this app and the sloppy developer who takes your money for giving you junk.

Spotty "paper tape"

The paper tape feature is/was pretty cool, until I cleared it for a second calculation. Then it wasn't there and I couldn't get it back!! Now I have a standard basic calculator. What a waste.

Don't understand...

I have tried both this and Crystal Calc both by same author and have had no issues at all. It is possible the glitches don't 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.

NO APP SUPPORT

BuzzNae

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!

PEMDAS

Pac_Man_WAKA

I'm in algebra and I needed to check my homework, so I got this app. But it kept giving really high numbers. I did some experimenting and found out it doesn't have one of the most basic functions of a calculator PEMDAS, or Parenthesis Exponents Multiplication Division Addition Subtraction. This an order you do things in a problem. Example: (5+2) + 5^2 + 5 x 2. This equals 42 but the calculator will say 298 therefor you really need to fix this because this will cause many problems to be wrong. Until fixed this should be taken down. It can do things like 5 + 2 but most calculators on phones can do this anyway.

How can I concentrate when it's screaming animated ads in my face?
