CalcPad vs Nummeric

CalcPad is not just another calculator app among the many calculator apps. Why? If you are using a mobile calculator app. You will find that it calculates differently from a physical calculator. Since the calculator app uses a process known as PEMDAS or BODMAS for its calculations, while a physical calculator uses a step-by-step calculation. For example 5+5/5, on the physical calculator, you will get the answer equal to 2. But if you do it on the calculator app, the answer will be equal to 6. Because the calculator app will use the principle of PEMDAS/BODMAS. It is calculated using parentheses, division, multiplication, addition, and subtraction, but a physical calculator does it step by step. That's why you will get different results. Calculator users who want to perform sequential calculations will not be able to use most calculator apps. CalPad was created to fix this problem. Basic features - Calculated in sequential order, not using PEMDAS or BODMAS. - Works on both iPhone and iPad. - Display in both portrait and landscape on all devices. - Large NumPad buttons on every screen and do not change the position of the button for easy muscle memory use. - Support basic scientific calculations. - And most importantly, it's FREE, NO ADS!
