Calculator N+ is also one of the best free science apps on Android and iOS. The built-in calculator of your phone may suffice for normal everyday calculations, but when it comes to scientific matters, it is almost useless. For that, you can use the N+ Calculator. It can perform manual calculations of complex equations and problems. If necessary, it can also draw graphics for you.

Keep in mind that unlike WolframAlpha which can handle many different domains, Calculator N+ only supports Math. Also, it will not show the steps to solve the equation, only show the final result.
