Key Features
✓ Pros
- Speed — Gauth returns solutions faster than any other camera-scanning tool tested. Point, scan, answer — usually under 3 seconds for standard problems. When you're working through a 40-problem worksheet, speed matters
- 14-language support — English, Spanish, French, German, Japanese, Korean, Portuguese, Indonesian, Filipino, Italian, Malay, Thai, Turkish, Vietnamese. The broadest language coverage on this list, making it the default choice for non-English-speaking students
- Live tutor option — The Tutor tier ($19.99/mo) connects you with a human tutor for problems the AI can't handle or when you need a real conversation. It's expensive, but having the fallback is valuable for complex topics
- "Super Gauth" AI engine — The Plus tier uses a more capable model that handles multi-step word problems, proof-based questions, and advanced topics better than the free tier's solver
✗ Cons
- The most expensive tool on this list at $12/month for AI-only or $20/month with human tutors. Hard to justify when Photomath's free tier covers many of the same problems
- Heavy advertising and upselling on the free tier — the experience feels designed to push you toward Plus rather than provide genuine value at the free level
- Solution explanations are adequate but not exceptional. The steps are correct but the explanations read like a textbook — functional, not engaging
- Covers math, science, and some humanities, but math is clearly the primary focus. Non-math subjects feel like afterthoughts
Full Review
Gauth (formerly Gauthmath) has quietly become one of the most-used homework apps globally — 50 million+ installs on Google Play, 16.7 million monthly website visits, and support for 14 languages. The app is mobile-first in a way that the other tools on this list aren't: the camera scanning, solution display, and navigation are all designed for a phone screen, not adapted from a desktop experience.
Students who work primarily on their phones and value speed over depth. The 14-language support makes it the best option for international students or non-English speakers. If you're price-sensitive, Photomath's free tier covers similar ground at no cost.
