A calculator app is one of the most basic yet important apps on your phone. You need to deal with calculations everyday and a calculator app allows you to use your smartphone for all the calculations on the go. 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.
