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.

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.

The ads on this one were not something I wanted to deal with so I paid to remove them. I love that it has a dark mode - everything on my phone is dark mode. You can adjust thin, normal, bold, or auto font but cannot adjust the size. I wanted it smaller. The trigonometric often showed up in the middle of calculating just adding and subtracting. I never figured out why. Please add a feature to turn off trigonometric altogether. Otherwise it's a great app.
