I've used this app for around 10 years, it's perfect. Its design, functions, overall simplicity and yet still having a room for some complexity made it perfect for me. Although my education is over and I moved to apple's environment for good, I still miss it, it's that perfect. Thank you for making the best calculator I have ever used. Absolute must have.

I tried more than 10 calculator apps since 2017 and ever since I found this one I never looked back. Been using this as my main calculator for more than a year and I really think it is anything you could ask for. Does 2+2x2 correctly for one. You can also go back and forth correcting typos in your equation if you mess up a number and realise afterwards, result updates dynamically. Simple yet excellent. Highly recommended.

This can be the best calculator app for a under graduate student in the whole world. It has all the required functions for a UG student, have 2D and even 3D graphical solution. I have been using this app since 2-3 years and it never failed to help me. And the best thing is it's ABSOLUTELY COST FREE. I want to thank the developer from the bottom of my heart.
