sketchometry vs GeoGebra Geometry
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.
GeoGebra Geometry
Create geometric constructions like triangles, lines, and circles. Explore interactive geometry by dragging elements, measuring lengths and areas, and transforming shapes. Save and share your creations, and discover learning activities.
- Construct points, lines, circles, and polygons
- Explore interactive geometry by dragging
- Measure lengths and areas
- Transform shapes (mirror, rotate, dilate)
- Advanced constructions with conics and locus
- Investigate construction steps
- Search for learning activities

Verdict
The clearest difference is rating: sketchometry at 4.6 against GeoGebra Geometry's 4.0. sketchometry also leads on update cadence (every 10 days vs monthly) and review sentiment (65% vs 55%). GeoGebra Geometry's advantage is ratings volume (75 vs 5). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
sketchometry holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: GeoGebra Geometry has 75 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 65% of sketchometry's written reviews are positive against 55% of GeoGebra Geometry's.
sketchometry ships an update every 10 days, GeoGebra Geometry monthly. The most recent releases landed on October 12, 2026 and October 13, 2026 respectively.
