Calculator‰

I bought a couple other calculators -- the screen were crowded with functions I just don't ever need and, to make things worse, the advertisements were constant and sometimes wouldn't allow the calculator to function until the "ad time" elapsed. This one is pure-T perfect. Sure, if you're a scientist of an engineer, you might need one of the other ones, but I'm not and having unused functions on the screen is a waste of space. This one is great across the board.

I compared the TOP 10 calculators, and this is THE VERY BEST CALCULATOR APP... IF you're looking for the following qualities: 1) BASIC, SIMPLE 0-9 +-x ONLY...without all of the "Bells & Whistles" (I think the geeks call those "Scientific Calculators"?) Simple! Simple! Simple! 2) THIS CALCULATOR OPENS INSTANTLY! In my opinion my calculator should be there, READY to do a quick calculation, so I can continue my work seamlessly without delays. Waiting for a BASIC HELPER-APP to open, while deep in my work, TOTALLY breaks my train of thought. (MANY of the highly-downloaded calcs that I compared took 15-THIRTY SECONDS just to OPEN! That's like a LIFETIME when you are on a roll, working. Completely unacceptable. 3) !!!!!!!!NO ADVERTISEMENTS!!!!!!!! (However, even if there WERE ads, and I was offered the option to pay $.99 to remove them, I would TOTALLY pay the $.99. It's THAT good of a SIMPLE CALCULATOR! 4) VERY EASY ON THE EYES.

This is a great no frills calculator and is big enough for 60 plus eyes. Deleted the one that came with iPad Air. My one small but is that bright red background of the "C". It is just like the red notifications on FB or Messenger or Mail!! Drives me crazy. Every time I would open iPad, I'd for a split second, think I had notifications. Had to move it off home page so I now have to swipe to use it. Change it to some other color or give us a choice.

Has everything I need. Percentages, square roots, basic math. I had one with trig functions, which was overkill. Trig was the only class I ever failed in high school, so cosines and tangents are not useful for me. And so far it hasn't shown any ads. (I don't mind an ad placed discreetly, but the first two iPad calculators I tried had banner ads at the bottom with lights moving around the borders – very very distracting. I also wouldn't mind paying for simple calculator app like this to keep it ad free

I have had no problems with the Ap,even though at one time Apple wanted it removed and replaced because of potential security issues. I looked for other Ap's, but none of them were as satisfactory as this is. The others had a ton of advertising I had to go through, so they were uninstalled. I was never a Apple Type Computer user, but I am changing because so far, their security is the best I have worked with so far!
