sketchometry vs Cabri Express
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
sketchometry
This app transforms your finger drawings into precise geometric shapes on your iPhone or iPad. It turns math into an experimental subject, encouraging learners to discover concepts through hands-on interaction rather than presenting pre-made solutions.
- Finger-to-geometry conversion
- Dynamic mathematical exploration
- Experimental learning approach
- Interactive geometric drawing
- Supports iPhone and iPad

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.
