Gauth is free to download and you can start asking questions without paying, but it isn't fully free. The developer's App Store listing says Gauth Plus is what gives you unlimited detailed explanations, unlimited top models, better accuracy and priority expert help, and as of October 2026 Plus is listed at $11.99 a month in the US.
Gauth is the AI homework and study app from Gauthtech, and it's popular: its App Store page shows a 4.8 rating from 1.5 million ratings. Here's what the developer says is included, what the paid tier adds, the prices listed as of October 2026, and how to avoid paying for a trial you forgot about.
What Gauth does
Gauth's listing describes it as an AI study companion. You can photograph or type a question and get step-by-step guidance, talk a problem through with an AI Live Tutor by voice with a virtual whiteboard, turn notes, audio or lecture links into quizzes and flashcards, and ask a network of human subject experts for help. It covers maths, biology, physics, chemistry and other subjects, and it includes writing, reading and focus tools such as a grammar checker and a study timer.
Gauth free vs Gauth Plus
| What you want | Free download | Gauth Plus |

The developer doesn't publish an exact daily limit for free users on the listing, so here's the fair summary: the app works for free, and the listing says the unlimited version of its best features is the paid one.
How much Gauth Plus costs, as of October 2026
Gauth's listing gives three standard US prices for the Gauth Plus membership:
- Monthly: $11.99 a month.
- Quarterly: $31.99 every three months.
- Annual: $99.99 a year.
Here's the part people miss. The in-app purchase list on the same page shows far more than three options: a quarterly plan with a 3-day free trial at $31.99, an annual plan with a 3-day free trial at $99.99, a quarterly special discount at $26.99, an annual special offer at $49.99 and a monthly win back offer at $11.99. The listing also says actual prices and introductory offers are shown in the app and may vary by region. So the price on your paywall screen can be different from your friend's, and the trial you tap might roll into a quarterly or yearly plan rather than a monthly one.
Working it out: the annual plan costs less than nine months of the monthly price. If you'll only use it for a single exam season, monthly or quarterly is less of a commitment.
How to cancel a Gauth trial or subscription
Gauth's listing says the subscription charges your Apple account within 24 hours before it expires, and that you need to turn off auto-renewal at least 24 hours before the billing cycle ends.
- On iPhone, open Settings, tap your name, then Subscriptions.
- Tap Gauth and choose Cancel Subscription.
- Do it at least a day before the trial or billing period ends.
- On Android, open Google Play, tap your profile, then Payments and subscriptions, and cancel there.
Deleting the app doesn't cancel a subscription, so always cancel in the store first.
Free alternatives to Gauth
If you only need help with the odd problem, a free tool may cover it. I've rounded up the free AI homework helpers worth trying, and my guide to the free AI math solver options covers maths in more depth. Use any of them to understand the method, not to copy answers, because your teacher will ask you to show your working.
What subjects Gauth covers
The listing says Gauth covers maths, biology, physics, chemistry and other subjects. For maths it lists word problems, algebra, functions, geometry, trigonometry and calculus among its topics. It also describes a DeepThinking mode for harder questions and a Smart Study Converter that turns notes, audio or lecture links into quizzes and flashcards.
Those study tools are what make Gauth more than an answer checker. The listing's pitch is conceptual learning: step-by-step guidance and the why behind the facts. That's the way to use it, too. Read the method, close the app, and try the next problem yourself.

What to check on the Gauth paywall screen
- The plan length the trial turns into: monthly, quarterly or yearly.
- How long the trial lasts. The listing shows 3-day trials.
- The renewal price after any introductory or special offer.
- Which Apple ID or Google account you're paying with, so a parent can find and cancel it later.
If a child is using Gauth on a family device, it's worth turning on purchase approval in your phone's family settings before they start.

My verdict: is Gauth free?
Partly. You can download Gauth and use it without paying, but the developer is clear that unlimited explanations, the top models and priority expert help come with Gauth Plus, listed at $11.99 a month in the US as of October 2026. If you start a trial, check which plan it's attached to before you tap, set a reminder two days before it ends, and cancel in your phone's store settings if you don't want to keep it.
