Fascinatingly simple. Simply fascinating. sketchometry is a different kind of dynamic math software. You draw with your finger on your iPhone or iPad. sketchometry automatically converts these (finger) sketches into exact geometric objects. Mathematics becomes an experimental subject. No ready-made results are presented, learners are encouraged to go on a journey of discovery by themselves.
