I love the app and use it often. we all know it needs more options in the conversion section, like currency and power/torque, etc. Since my phones last update, my cursor is on the left side of the 0 instead of the right. So, any numbers you type in, that 0 stays there in your calculation unless you clear it every time you use the app. Edit: I just uninstalled and reinstalled it, and it works fine now. I did lose all my recent calculations.

Wonderful free calculator app, with no ads, and you can use it with no internet connection. I only use it for basic math problems, so if you need to use it for complicated problems, I'm not sure if this will work for you. My favorite part is the memory (history), so you can see what you did previously and recall certain numbers, and can clear it completely and easily whenever you want.

It's a calculator app it does what it's supposed to do without adds or any random issues. These 1 star reviews for cosmetic stuff can't change the color, or you don't know how to turn off that click with each button press, are silly. It takes up minimal storage, opens quickly, and does the math I'm either too lazy to do or don't want to do. And that math teacher kept saying you won't have a calculator in your pocket all the time.
