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.

Dear Tiffany. It seems something wrong with your device or its settings. Could you please write to our developer at calc@mathlab.us and explain him what happened when the app stopped to work. Send the copy of that email to me at buzz@mathlab.us, and I'll gift you the promo-code the get the PRO version.

I love everything you can do on it. It definitely gives you the flexibility for almost everything! -(Update)- So originally I gave this calculator app five stars, and YEARS later I'm giving this an update. I've been using this calculator for years and simply it will do just about EVERYTHING you can throw at it. Its so pack full of features and options. From simple computational tasks, to inputting complex functions. I only wonder why this app is free... oh yeah it has ads, but its no bother.

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.
