Euclid Lab
Learn classical geometry by constructing each proposition yourself. Euclid Lab combines semantic straightedge-and-compass tools, proof workbooks, hints, and step-by-step replay in one focused learning experience.
Foundations + Book I
Semantic construction
Local-first learning
Geometry You Can Build
Euclid Lab turns propositions into interactive construction challenges. The app checks the geometric meaning of each step rather than asking learners to imitate a fixed drawing.
Construct
Use straightedge-and-compass tools to create points, lines, circles, intersections, and proof-relevant relationships.
Reason
Work through Foundations and Euclid's Book I with proposition context, guided hints, and a proof workbook.
Review
Undo or redo steps, replay a construction, and revisit completed work through a local Learner Profile.
One Product Family Across Platforms
Euclid Lab is available for Apple and Android devices, with platform-specific privacy information where the software and store rules differ.
Mac
The App Store version is compatible with supported Apple-silicon Macs. Apple identifies it as designed for iPad and not separately verified for macOS.
Android
The Android edition belongs to the same Euclid Lab product family and has dedicated Android privacy and terms pages.
Learning Features
Start with Foundations and Book I propositions I.1–I.12. The Apple edition also offers I.13–I.24 as a one-time purchase.
Semantic tools
Constructions are evaluated by geometric relationships, not by approximate screen placement.
Proof workbook
Record reasoning alongside each construction and review the sequence step by step.
Learner Profiles
Keep learning progress and preferences on the device.
Encouraging practice
Points, feedback, and optional encouragement audio support steady practice.
