It is a great app with many ways to calculate and not just mathematics but also convert feet to miles to yards to cm. Kitchen measures to bake, ounces to pints to litres to pounds. I've had no problems using it, and so far, no faults with the app. Edit Update: One other calculus function I would like to see as an additional feature to ClevCalc. I'd add an Electrical/Electronic resistor colour banding decoder. Plus, have the other electrical formulas for voltage, current, and wattage added.

Very good for what I wanted, a straightforward calculator. On installing it, I found it has conversion tables for everything plus a currency converter that updates the day rate before you use it. The adverts are not obtrusive. All in all " tip top". Having looked at the optional section I don't see why any one woul want to use any of them. After more than two yearsof use my views of this application are unchanged. Still "Tip Top"

Seriously good calculator. Lots and lots of options but still has a simple look. Love the history feature which works perfectly. If I could've wrote down everything I needed in a calculator app........well, it's all here. Used it for a week or so before purchasing and reviewing. I use it daily and figured it was well worth the payment to the developers. Not to say that the ads are intrusive, they're really not, but it is well worth the cost of a cup of coffee. 👍
