Pretty good app; however, it's been almost a year since the app was updated, which makes me wonder if it is still being supported.

The percentage key converts a percentage to its equivalent decimal. E.g 20% gives 0.2. So to find 20% of a value, e.g. 50, write 20%×50 or just 20%50. To increase by 20% therefore 50+20%50. This calculator is mathematically rigorous and doesn't change the operation of a symbol depending upon its position in an expression.
The easiest most comprehensive calculator I've found to date. This has become a valuable tool for me I constantly use it in my work day.
Finally! A decent app to help me calculate when I'm working on construction project. And the price was decent for this. I appreciate that. The calculator is basic and works just fine. I can calculate all of my fractions, back and forth from decimal back to fractions and vice versa. For 99 cents it was worth it. Thank you

After spending some time with this calculator, I'm really liking it a lot. Still learning but I love it! Nice work!
Excellent.

I have installed and tested a great many calculator apps, both basic and scientific. Being a retired Professor of Mathematics, I have both the time and the interest to do so. This particular app is the most impressive basic calculator of the many that I tested. The developer, Mr. Stephens, has done an absolutely splendid job. Kudos to you, sir. Update: I have just installed the ad-free version of developer's new scientific calculator based on the same user interface. In the short time that I have used it, it has become my hands-down favorite scientific calculator.
