Most people can draw freehand circles with better than 90% accuracy. But can you do better consistently? By repeatedly practising drawing freehand circles using the feedback you get from this app, you will eventually get to be so good that the best artists of the world will envy your freehand circle drawing skills.

By drawing good circles you will be able to unlock the lines of a special ode. Unlock all 16 lines to win.

What are you waiting for. Get out there and draw!

P.S. Freehand is based on the algorithm described by Dale Umbauch and Kerry N Jones in "A few methods for fitting circles from data", IEEE Trans. Instr. Measurements, Vol 52, No. 6, Dec 2003.
