Ratings and reviews

Hello Developer, Thank you for creating this calculator app. I have a couple of suggestions that could make it even more useful: Add an auto-calculation feature so the result updates automatically as numbers and operations are entered, without needing to press the equals (=) button. Improve the expression display. When entering a long calculation with many numbers, the entire expression should remain visible on the main screen, so users can easily review what they entered

Never liked the calculator that came with the phone. Found another app that I liked but it seems that updates over time began to make the app hang up as well as the phone. Stumbled on to this one by accident and I love it. It's smooth and the several different themes means there is one you will probably like. It is both a simple calculator and a trigonometry calculator. I couldn't ask for more.

I really like the calculator a lot and would give it five stars except, I bought the ad free version and I still get ads. They don't go away. **I see I had both apps installed an was using the wrong one. That is confusing. Thanks for clarifying it.
