30-Second Verdict

Should you use Gauth?

Best for

Middle and high school students who want one app that scans a math or science problem and walks through the steps in a teacher-like voice.

Skip if

You work on advanced or proof-based problems , where users report it answers wrong and then refuses to correct itself.

Real cost

The website hides prices. In the app it is $11.99/mo or $99.99/yr , usually after a trial that auto-renews at full price.

Watch out

On free web, the answer is blurred behind a login , and multiple users say a cancellation error kept charging them for months.

Capabilities

Key features & how they perform

Each feature rated from hands-on testing and aggregated review sentiment.

📸
★★★★☆ 4.3

Scan and solve

Snap a photo or type a problem and the AI crops it, reads it and returns an answer in seconds. Recognition on printed work is consistent.

🪜
★★★★☆ 4.2

Step-by-step teaching

Answers arrive with grouped steps and plain-language reasoning rather than a bare number, so a student can follow the logic.

🧪
★★★★☆ 4.0

Multi-subject range

Math, chemistry, biology, physics and more across 30-plus subjects, including balanced equations and comparison tables, not math alone.

🧑‍🏫
★★★☆☆ 3.3

Live tutors & voice tutor

Human tutors answer within minutes, but each request spends a ticket. A newer AI voice tutor some users find unsettling.

🎓
★★★☆☆ 3.5

Academy & writing tools

An Academy builds mini-courses on a chosen topic, and the AI will write a full essay, which blurs the line between help and doing the work.

🎯
★★☆☆☆ 2.5

Answer accuracy at the edges

Reliable on standard K-12, but users report confident wrong answers on harder problems and the AI refusing to fix them.

Feature ratings blended from the App Store, Google Play, Trustpilot & Product Hunt + hands-on testing.

Hands-On Walkthrough

Where Gauth Delivered and Where It Stalled

I ran the free web version at gauth.com through school-style problems to see what a US student actually gets without paying.

First look and setup

The homepage keeps things simple. One text box sits in the middle, with a drag-and-drop area below it for uploading a photo of a problem.

I typed my first question straight into the box and hit the arrow. No sign-up screen blocked me from asking.

What I noticed The page stayed clean with no ads crowding it, which is rare for a study app aimed at students. Getting straight to a question with no account was a good start.

Solving a basic math problem

I started with a straightforward algebra question to see how it handled the core job: solve for x in 3x + 7 = 2x + 15.

Gauth returned x = 8 and walked through the working underneath, rather than stopping at the number.

My take The answer was correct, and the tone stood out. It wrote in a teacher voice, explained keeping an equation balanced like a scale, then grouped like terms and used inverse operations. A student could follow the reasoning instead of copying a bare number.

Pushing past math into science

Next I tested the subject range in a single prompt. I asked it to balance C3H8 + O2 and to compare mitosis with meiosis at the same time.

It handled both halves without dropping either one. The chemistry came back balanced, and the biology arrived as a clean comparison table.

During testing It balanced the equation correctly to C3H8 + 5O2 producing 3CO2 + 4H2O, then laid out a table comparing the two cell-division processes by purpose, daughter cells, number of divisions and genetic makeup. The subject range here is real and goes well past arithmetic.

A trick question it did not fall for

I wanted to see whether it would invent an answer when a question was missing information, so I asked for the area of a rectangle when only the perimeter was given.

Observation A weaker tool would guess. Gauth did not. It said the area cannot be worked out from the perimeter alone, then added that a square would give an area of 36. Flagging the missing information is a point in its favour, though a rushed student might copy "36" and skip the warning above it.

Building a full course in Academy

Gauth has an Academy section that builds a mini-course on a topic you choose, going a step beyond a single answer box.

It offered ready-made course topics and a field to request my own, trying to teach a subject in order rather than hand over one solution.

Worth knowing One detail sat at the bottom of the screen: a small line reading "Remaining uses today: 3." That was my first sign the free plan runs on a daily cap.

Asking it to write a whole essay

To test the schoolwork-integrity angle, I asked Gauth to write a 300-word essay on the main themes in The Great Gatsby.

How it went It wrote the whole thing, opening on the corruption of the American Dream and moving into social class and status. It read like a finished submission rather than a study aid. For a parent or teacher, this is the uncomfortable part: the tool does the assignment rather than coaching the student through it.

The answer got walled off

The free run stopped being free the moment I tried to read a full solution. I asked a short logic question about eggs.

Gauth showed the solution box with the answer blurred out behind a button reading "Check answer now." Clicking it asked me to log in.

After I logged in, the answer still did not show. A pop-up appeared instead, pushing me toward the mobile app with a QR code and a line about unlocking cross-platform features.

The result So the website solved the question, then hid the result to funnel me into an account and then into the app. On the free web version, reading your own answer is not guaranteed.

Mobile web did not work at all

I tried the same flow on a phone browser to see whether mobile users had an easier time. They did not.

The takeaway The page threw an error reading "Something went wrong. The application couldn't be opened." There was no working mobile-web version to fall back on, which pushes phone users straight toward installing the native app.
Plans & Cost

Gauth pricing

The website only shows a free plan and a 3-day trial, so these figures come from the official App Store in-app purchase list.

Plan Price What's included
Free $0 Limited daily answers and AI queries · standard AI courses · 10 Atlas credits/mo · 3 tutor tickets · full answers often walled behind login
Monthly Popular $11.99 /mo Unlimited answers and AI queries · Super Gauth AI engine · ad-free · 24/7 tutor help · 100 Atlas credits/mo · premium AI courses
Quarterly $26.99 /qtr Same PLUS access over three months · listed from $21.99 up to $31.99 depending on the offer shown (back-to-school, discount, new-user)
Annual $99.99 /yr Full PLUS access for a year · usually sold behind a 3-day free trial that auto-renews at this price unless cancelled first
Trial 3 days Unlimited answers, AI queries and premium courses · converts to a paid plan automatically when the 3 days end

Pricing is accurate as of 22 October 2026 and was captured from the official Gauth App Store listing. Plans, prices and limits change often, so check the official Gauth pricing page for the current figures before you subscribe.

⚠ Read this before paying Gauth's website never shows a price, listing only a free plan and a 3-day trial, so the real cost only appears in the app stores. The same quarterly plan is sold at $21.99, $26.99 and $31.99 across different "offers," making a clear comparison hard. The trial auto-renews at the full plan price when it ends, and multiple users report a cancellation error that kept charging them, one to a total of roughly $324. On free web, your solved answer is often hidden behind a login you still cannot read it through.

Who Should Use Gauth AI, and Who Should Avoid It?

Gauth is fast and genuinely helpful on standard school work, but accuracy at the edges, a walled free tier and billing complaints make it a poor fit for some students.

Who Should Use Gauth AI?

Best suited for these workflows

Middle and High School Students

Standard algebra, geometry and intro science is where it is most reliable, and the stepped working helps you learn the method, not just the answer.

Visual Learners Who Scan Their Work

A photo of a printed worksheet turns into a solved, explained answer in seconds, which beats typing long equations by hand.

Students Who Want to Check Their Work

Solve a problem yourself, then use Gauth to confirm the answer and spot where your method went wrong.

Learners Across Many Subjects

One app covers math, chemistry, biology and more, so you are not switching tools between a math set and a science assignment.

Who Should Avoid Gauth AI?

Consider an alternative if you need

Accuracy on Advanced Problems

On proof-based or higher-level work, users report confident wrong answers and the AI refusing to change them, so every answer needs checking.

A Free Answer You Can Actually Read

On free web the solution is frequently blurred behind a login, and logging in can push you to the app instead of showing the answer.

Simple, Safe Cancellation

Multiple users report a network error blocking cancellation while the subscription keeps charging, in one case for over two years.

Easy Live Tutoring

Human tutors run on tickets that are hard to earn, and a wrong answer still spends one, so free help runs out fast.

Our Recommendation

Gauth is worth trying if you are a school student who wants fast, well-explained help on standard homework and will treat it as a check rather than a source of truth. If your work is advanced, or you need a free answer you can read without an account, look elsewhere. Before you subscribe, confirm the current app-store price, start the trial only once you know how to cancel, and verify every answer on anything past basic K-12.

Final Verdict

A sharp homework solver wrapped in a tier built to charge you

On the job it was built for, Gauth is good. It reads a photographed problem fast, covers far more than math, and explains its working in a voice a student can actually learn from, which is why it sits at the top of US education download charts. The trouble starts at the edges. Users report confident wrong answers on harder problems and an AI that refuses to correct itself, the free web version hides your own solved answer behind a login, and the mobile web flow simply broke in testing. Worse, the website never shows a price while the app stores list the same plan at several figures, trials auto-renew at full cost, and a recurring cancellation error has kept charging people, one to the tune of roughly $324. Owned by ByteDance, it also carries the same data questions that follow the company's other apps. School students who want quick, well-explained help on standard homework, and who verify anything advanced, will get real value from the free tier. Anyone on harder coursework, or who wants a clean free answer and a subscription they can leave, should weigh a study tool like Studley or stick to a solver they can cancel without a fight.
