FullProof review
A web-based proof practice system with flexible solutions and teacher tools.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
FullProof is a browser-based system for practicing geometry and trigonometry proofs, aimed at students from middle school through undergraduate level and the teachers who assign their work. Students solve open-ended problems drawn from textbooks and examinations using interactive diagrams and an equation editor to enter complete proofs. Its emphasis is on proof practice rather than a broad set of geometry learning activities, making it most relevant to classes where students need to construct and explain solutions.
A key strength is that FullProof accepts multiple valid solution paths instead of requiring one prescribed sequence. It provides step-by-step feedback and hints, then automatically evaluates and scores proof work. That combination suits formative practice: students can work through a proof and receive guidance while teachers can use exercises for homework or classroom practice. The published feature set also includes problem practice and dynamic constructions, but the product's described center of gravity remains open-ended proofs.
Teacher tools include class and assignment creation, student work monitoring, and progress reports. According to FullProof's help center, creating classes requires a school purchase, and purchase inquiries are directed to email; the vendor does not publish a public price. FullProof runs in the browser and is cloud-deployed, with email and documentation listed as support channels. It is a fit for schools seeking structured proof assignments and reporting, but less suitable for buyers looking for transparent self-serve pricing or a wider geometry platform with a verified integration ecosystem.
