Ratings and reviews

This is the very best calculator ever. The description of the app by the author does not point out the half the cool stuff. I even persinalized each button!!! Menus are intuitive, easy to use, without unnecessary steps. I just ask to developer to include the switch between binomial and polar complex form in some button instead in the lateral menu. Any case i love the app!!!

I'm using this app from an year, and regret that I didn't find it sooner. The app is simply awesome and I feel like small improvements can be made to do it better. Like solving linear and quadratic equations. Its taking a lot of time to fill both the variables and constants and that could be made better by giving blanks to the constants, it will be easier for calculation...

It seems that implicit plot has problems handling transcendental equations like "sin(x*y)= k". It might be a good idea to add a warning about that. EDIT: You are right, there is no problem at all. The calculator was in Degree Mode. Changing it to Radian Mode makes everything behave as I was expecting. Thanks for your hard work on the calculator and for the response!
