Ratings and reviews

Editing again...1 star. If I could put negative stars, I would. **DO NOT USE THIS APP!!** I don't mind banner ads. I understand that people got to make money. I have an issue with unexpected full screen ads that come in the middle of a calculation, never end, and can't be closed. The only way to make the full screen ads go away is to force close the app and reopen it, losing whatever you were working on. Also playing loud video ads while the app is minimized in the background is just wrong.

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.

The best calculator layout I've seen for Android. All of the regular functions are close at hand, and there is no practical limit to digit count in calculations. The only two things I have a minor gripe with are how often the settings screen swipes up when I'm doing calculations, my finger moving just minutely enough to trigger the action, and the fact that there's no way to back up my settings. It pretty easy to set the calculator up the way I like, but a quick backup and restore would be nice.
