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.

Verdict
The clearest difference is rating: sketchometry at 4.6 against Isometric Paper's 3.5. sketchometry also leads on update cadence (every 10 days vs every 16 months). Isometric Paper's advantage is ratings volume (41 vs 5) and iOS requirement (9.0 vs 15.0). On price, review sentiment, ads and in-app purchases there is nothing between them.
