What does it do?

I don't understand what this app is supposed to do. Is it just a drawing program? I cannot find any action buttons, such as "Create Fourier transform." The description says "I will create..." -- is that "I" the app or the developer?

Very Nice

I enjoy the apps simple interface. It gets it done clean and simple.

Great learning tool and fun to use.

I look forward to it evolutions.

Wish there was a numerical output

I wish there could be an option to see the coefficients (radius and initial angle) for each vector in the result.

Response from developer

Hello, thanks for your feedback! The new update now allows you to copy the Fourier coefficients in the equation result including the radius, initial angle, and angular velocity in csv format. Jack
