About Gauthmath
What Is Gauthmath
Gauthmath is a study app that solves homework problems for students, and it now goes by the shorter name Gauth. You point your phone at a question, the app reads it, and it answers with worked steps instead of a bare result. It started as a math solver and grew to cover physics, chemistry, biology, economics and writing, so the same tool handles most of a school night.
The app was built inside ByteDance and released in late 2020 as Gauthmath. In 2024 the team dropped the "math" from the name to signal the wider subject range, and the rebrand came with Gauth GPT, a model the company trains on its own bank of questions. That library is the reason common textbook problems come back fast and accurately.
The biggest thing to know is availability. Gauth was pulled from the US App Store in January 2025 as part of wider actions against ByteDance apps, so American iPhone users can't install it there. Android and web users, and students outside the US, still have access. It is a study aid, not a way around doing the work.

Key features
Photo Problem Solver
The core of the app is the camera. You take a picture of a printed or handwritten question and Gauth reads it and crops the problem area automatically. It handles everything from clean textbook type to rough notes, which matters because most homework isn't neatly formatted. Results come back in seconds for most problems.
Step-by-Step Explanations
Gauth does not just hand over a number. Every answer comes with the solving steps and short notes on the "how" and "why" behind each one. That turns a homework shortcut into something closer to a lesson, and reviewers consistently say the breakdowns are the part that actually teaches. You can tap a step to expand it when a jump doesn't make sense.
24/7 Human Tutors
When the AI gets stuck, or when you want a person, the app connects you to real tutors around the clock. The company says its tutor network handles the hardest questions and cites a 98.5% satisfaction rate. Answers typically arrive in minutes rather than the 10 to 15 minutes some testers report at peak times. This is the feature that separates Gauth from a plain calculator.
Multi-Subject Coverage
Math is still the strongest area and covers algebra, geometry, calculus and statistics. The app also answers physics, chemistry, biology and some economics and business questions. Writing help and a reading tool that simplifies dense textbook passages round out the set. Depth thins out beyond the STEM core, which the app doesn't hide.
Gauth Atlas
Atlas turns a topic into a visual map you can explore. You click into a subject and follow connected ideas, zooming from an overview down to detail, with every image traced back to a source. It is built for curiosity rather than a specific answer, and it is aimed at students who want to understand how ideas link together.
Study Tools and Progress
Beyond solving, Gauth bundles a calculator, a focus mode, and tools for reading and writing. Problems you miss can be saved and revisited, so a review session becomes a list of your own weak spots instead of a scramble through old worksheets. Only the AI tutor answers feed back into that.
Pros and cons
Pros
- Photo recognition is fast and reads handwritten problems, not just clean print.
- Step-by-step explanations teach the method instead of only giving the answer.
- Human tutors cover the questions the AI can't handle, day or night.
- The subject range stretches past math into physics, chemistry and biology.
Cons
- Accuracy drops on complex or badly formatted questions, so you still need to check the working.
- Relying on it for every problem can become a crutch and skip the practice that builds skill.
- Full functions need a Gauth Plus subscription, and the free tier caps how much you can solve.
- Pulled from the US App Store in January 2025, so iPhone users there can't install it.
