I love this calculator, its my constant companion and it should be. It prevents me from going over budget because I let it keep an eye on my spending. Now, I know what you are thinking...a calculator can only receive input, it doesn't give out anything....oh...but it does...its easy to handle and record, I use the history feature often and most of all, it addicts my conscience and that keeps me from going into debt....I just love it! I love the color too!!! Enjoy!

As others have stated. Get rid of the loud annoying clicking. The app was fine until the update to add sound that can't be turned off. Yes the work around is the turning volume off via the wrench. But in so doing that it also affects other apps I want the sound, so that is not a valid solution. Not sure who's the moron is that came up with the idea but it's NOT A GOOD ONE. I'll be uninstalling and finding a viable alternative.

What happened?? It doesn't look like or feel like a calculator at all! It was fine before update. The number font is much too fine and too small. I have a large phone screen and they fill about half the screen. The rest is blank white space. Use bolder font to avoid eye strain. Calculators don't need to look pretty; they need to be functional. I've used calculators all my life, mostly small pocket size; my fingers can fly when working, but not on this one. I may need to look for another.
