Calc+ Is a newer, good looking calculator. It has a lot of the same aesthetics as Google Calculator and most stock calculator apps. However, it has some decent functionality. You get the basic arithmetic and some algebraic functions. The app also includes theming, a history that you can view, and you can change equations after you hit the equals button. There are a few more, but we don’t think many will care about sharing equations with friends. In any case, this is a perfectly acceptable replacement for a stock calculator app. It’s also completely free with no in-app purchases or ads (as of the time of this writing).Calcu is one of the most popular calculator apps for Android. It features all of the basics. Some other features include a calculation history, memory keys, various customization features, themes, and gesture controls. It’s not a full scientific calculator, but it does have enough functions to go beyond what you normally find in basic calculators. The free version of the app contains advertising.
