人気の 5 ツール。どれが本当に無料・段階的解答付きで幾何宿題を解けるのか？以下は正直な並列比較です。
Desmos, GeoGebra, Mathway and Symbolab are excellent tools — for the use cases they were built for. None of them is a geometry-first homework solver, which is exactly the gap GeoCalc Pro fills. Below: an honest comparison so you can pick the right tool for your problem.
| GeoCalc Pro ★ | Desmos | GeoGebra | Mathway | Symbolab | |
|---|---|---|---|---|---|
| Primary focus | Geometry-specialized (70+ calculators) | Graphing + scientific calculators | Interactive geometry + algebra suite | General algebra/calculus problem solver | Algebra/calculus/equation solver |
| Geometry depth | Deep — SSS/SAS/ASA, proofs, composite figures, coordinate, 3D solids | Geometry tool exists but limited — drawing-focused, not problem-solving | Strong drawing/construction, weaker on numeric answers | Basic geometry, focus is algebra and calculus | Limited geometry — strongest on algebra and integrals |
| AI photo solver | Yes — upload photo, get step-by-step | No AI photo input | No AI photo input | Yes — but steps locked behind paywall | Yes — but limited free use |
| Step-by-step solutions | Always shows every step | Visual only — no written steps | Construction history, no algebraic steps | Paywalled — $9.99/mo | Some free; full breakdown needs Pro |
| Free tier | Fully free, no limits | Free for personal use | Free, open source | Answers free, step-by-step requires subscription | Limited daily problems; steps need Pro |
| Signup required | No signup, no card | Optional (saves work) | Optional | Required for steps | Required for full features |
| Best for | Geometry homework, proofs, area/volume problems | Function graphing, interactive math demos | Compass-and-straightedge constructions, dynamic geometry | Quick answers across all math subjects (if you don't need steps) | Algebra problems and step-by-step calculus |
★ = Recommended for geometry homework. Comparison reflects publicly available info as of May 2026; tool features change.
Geometry homework, area/perimeter/volume word problems, triangle/polygon angle calculations, two-column proofs, composite figures, photo-of-textbook problems. Fully free, always shows steps.
Function graphing, interactive math classroom demos, exploring conic sections visually. Not built for numeric homework answers.
Compass-and-straightedge constructions, dynamic geometry where you drag points and watch relationships, classroom interactive lessons.
Quick numeric answers across algebra, calculus, statistics — when you don't care about the steps. Step-by-step costs $9.99/month.
Algebra, calculus, equation solving, integrals. Some steps free, full breakdown needs Pro subscription.
For geometry specifically, yes. Mathway covers more subjects (algebra/calculus/statistics) but hides step-by-step solutions behind a $9.99/month paywall. GeoCalc Pro shows every step on every geometry problem for free.
Symbolab is stronger on algebra and calculus. GeoCalc Pro is stronger on geometry — proofs, composite figures, area/volume word problems — and always free.
Use Desmos for graphing functions or exploring math visually. Use GeoGebra for compass-and-straightedge constructions and dynamic geometry. For numeric geometry homework with step-by-step solutions, use GeoCalc Pro.
The tools are server-light (math, not video) so running them costs little. We support development through unobtrusive ads — no paywalls, no daily limits, no account requirements.
