Even though the default calculator app in most Android smartphones today is fairly feature packed and capable enough to handle a few complex equations. If you need a scientific calculator that can help you with all types of calculations and math problems, you will have to go for a third-party calculator app. Fortunately, there are many cool calculator apps available for Android that offer reliable features and the power to solve complex problems. We bring you a list of the 12 best calculator apps for Android to help you with all your calculations in 2020.
