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.

Verdict
The clearest difference is in-app purchases: sketchometry at none against Geometry!!'s 2. sketchometry also leads on ads (none vs shown) and update cadence (every 10 days vs every 7 months). Geometry!!'s advantage is ratings volume (56 vs 5). On price, rating, review sentiment and device support there is nothing between them.
