Ratings and reviews

I didn't know this was even possible, but this app will now TAKE OVER your phone with a full screen ad when you are NOT using the app. I've been trying to figure this out for a while, but about once or twice per day a full screen ad will take control of my entire screen with no "X" or simple way to close the ad. This entire time I thought I had been accidentally clicking ads in apps, but no! It's been CALCU! Horrible tactic!!! I've had a 5 star review here for 5 years. Not anymore.

Great, simple calculator app! I really like having memory keys and the ability to view a history of my previous calculations. I'm just using a plain black background, but some folks may like the extra background choices available. It was well worth the small upgrade price to get rid of the ads; they seem to be the main thing that other reviewers have complained about. Personally, I have zero tolerance for ads so I'm always willing to pay to remove them if the price isn't ridiculous.

Nice, clear, simple and easy to use calculator. A plus that it actually "remembers" any total balance etc., you may want to leave on the screen and return later. Many calculators here can't or don't offer that. For me, a big deal. In addition to THAT, as I had mentioned earlier, it's simple, yet fully functional. If you're looking for a more math detailed specific calculator, then look elsewhere. But for those of who want easy full function along with some nice style, then this fits the bill.
