| Compare | ||
|---|---|---|
| Verdict | Worth it | Worth it |
| Best for | Math learners ages 12-18 | Digital SAT math students |
| Who it's not for | Schools needing graded, standards-aligned curriculum | Symbolic algebra and CAS-heavy work . GeoGebra is stronger |
| Privacy | No public breaches found; npm build packages show minor vulnerabilities; privacy handled under Amplify's policy.⁹ | No known breaches of Desmos itself; security databases flag malicious npm lookalike packages, not. |
| Support quality | No support evidence found | No support-quality evidence in sources |
| Public sentiment | Reviewers consistently call Mathigon interactive, effective, and completely free, while some longtime fans worry about its post-Amplify direction.³ | Users across G2, Reddit, and app stores praise Desmos for ease of use and test-day value, while a minority of SAT students complain it trivializes problems. |
| Biggest gotcha | Guess: free product means no dedicated support or SLAs; rely on docs and community² | Several 'desmos-graphing-*' npm packages are flagged malicious . install only official packages |
