Ratings and reviews

Very surprised and delighted to find a calculator app with so much functionality. I'm used to switching between different calculator apps with different individual functions when helping my kids with their homework. With 3 different workspaces to work in at the same time, big plus. Awesome calculator!!! Would recommend to anyone, especially students.

This app converts your cell phone in a great calculator, you have the regular options in a scientific calculator, but its nesting capacity allows you to perform complex operations, also if you change a value it makes all the calculatios again, useful if you need to use a formula several times. It has adds, but they normally stay at the bottom of the screen

Update to the update: Thank you for telling me that the Pro version works offline; however, this does not solve the problem of the FREE version not working EVEN WHEN ONLINE..."network connection error" when on Wi-fi network. This calculator has always worked fine in the past whether on network or phone data. Now it does not work. Update: I haven't been able to use this due to "network connection error". It doesn't matter whether I am online or not, same message. I've deleted and reinstalled. No luck... I used to love this app and recommended it to all of the students at the college where I work, but Issues have reduced my ability to promote it at this point.
