The only Calculator app you’ll need!

I’ve tried dozens of calculator apps on the App Store, and ClevCalc completely blows the rest away. Not only does it feature a powerful, seamless scientific calculator that handles everything from basic arithmetic to advanced trigonometric and logarithmic functions with ease, but it’s also an entire Swiss Army knife of useful tools.
The built-in history feature is a total lifesaver—being able to review and copy past equations means no more starting over because of a tiny typo. Beyond the math, I find myself using the unit converter, currency converter, and date calculators almost daily. The interface is clean, modern, lightning-fast, and completely intuitive. 
If you are a student, a professional, or just someone who wants a reliable, multi-functional calculator that outperforms the stock iOS app in every single way, download this immediately. Well-deserved 5 stars!

Calculator/ Converter

I have used this app multiple times over the past few years and have become dependent upon it. I work in wastewater applications and have to determine both metric and imperial volumes depending on the customer. It is simple and easy to use.
It works for me
