What changed this week
Sweep of
Integration rises from 4.2 to 4.3 for the 1 September 2026 launch of "Gauth AI Course", more than 200 AI-generated maths courses. Control (3.7 to 3.5), real price (3.5 to 3.3) and support (3.6 to 3.4) fall because Trustpilot (2.3 out of 5, 86 reviews) documents, with a name and date, an $11.99 monthly charge over more than two years ($324) despite repeated cancellation attempts blocked by a technical error.

Down on the latest sweep, but it was moving the other way before: it may be a one-off.
We have tracked it since August 1, 2026: 5 sweeps on record, with the score moving between 3.8 and 4.0. We publish the latest change here; the full series is not published.
What the internet says
On 1 September 2026 Gauth launched "Gauth AI Course", more than 200 AI-generated maths courses from Algebra I through AP Calculus, and the press release itself cites more than 200 million downloads since 2020, confirmed in the official announcement. Plus pricing ($11.99 a month, $31.99 a quarter or $99.99 a year) is unchanged. Trustpilot shows a 2.3 out of 5 rating with 86 reviews, well below the App Store's 4.8, and one review details being charged $11.99 a month for more than two years ($324 total) despite repeated cancellation attempts, with technical errors blocking the cancellation.
What the web repeats in favour
- Photo input and coverage of multiple school subjects in one app
- Since 1 September 2026 it adds "Gauth AI Course", more than 200 AI-generated maths courses from Algebra I through AP Calculus, with an option for students to generate their own lessons
What the web repeats against
- The best access sits in Plus, and a solved answer is not the same as guided tutoring
- On Trustpilot (2.3 out of 5, 86 reviews) one user details being charged $11.99 a month for more than two years, $324 total, despite repeatedly trying to cancel, with a network error blocking the cancellation every time
- The data-protection contact the privacy policy lists for Brazil is a bytedance.com email address, and its UK and EEA GDPR representatives are ByteDance-linked entities, a detail the brand does not highlight on its site

What it solves and what it does not
Gauth prioritises speed and breadth: photo, answer and steps in seconds. It fits checking an exercise, but its design encourages finishing homework more than demonstrating learning.
Best for: Quickly checking photographed homework, with an adult reviewing the steps.
The wrong-step test
- Use one printed and one handwritten problem with a real intermediate mistake.
- Check that it identifies the wrong step and explains why rather than only returning the result.
- Ask for an equivalent unsolved problem and complete it outside the app to measure learning.
