sketchometry vs Euclid Lab
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.
Euclid Lab
Read full descriptionHide full description
Explore the 48 propositions of Book I of Euclid’s Elements through reading, construction and proof practice. Euclid Lab separates proposition reading, straightedge-and-compass work and reasoning so you can focus on one activity at a time. Arrange supplied proof blocks to connect premises to conclusions. Scored exercises use semantic checks of geometric relationships and logical dependencies, not the appearance of a drawing or AI grading. Progressive hints and complete solutions, shown on request, help when you get stuck. I.7 currently offers unscored reading, exploration and notes. Freehand notes are also unscored and are not automatically verified as correct proofs. Foundations and I.1–I.12 are free. I.13–I.24 and I.25–I.48 are separate, one-time in-app purchases. Buying one pack does not unlock the other. No subscription is required. Learning progress and notes are stored locally on your device. Learner profiles are not Apple Accounts, and no Euclid Lab account registration is required. Restore Purchases restores eligible content access; it does not synchronize learning progress.

Verdict
The clearest difference is update cadence: Euclid Lab at every 3 days against sketchometry's every 10 days. sketchometry's advantage is iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
