Gauth is a free Android app from GauthTech Pte. Ltd. for students who want step-by-step help with math homework, covering word problems, algebra, geometry, trigonometry, calculus and statistics. Its AI Live Tutor answers by voice and explains on a whiteboard.
What to do after installing Gauth on Android
Gauth runs on Android 8.0 or newer. The current version is 2.11.0, updated on November 2, 2026, and the app first came out on March 30, 2021.
The core routine is photo first: snap a problem, and the app recognizes it and crops the question for you. Answers come with step-by-step explanations, which the developer says take only a few seconds.
It pays to look at the other entry points early. The AI Live Tutor takes voice questions and explains on a live whiteboard, and the study toolbox adds Reading, Writing, Focus Mode and a Calculator. Topic coverage runs from algebra and geometry to trigonometry, calculus, statistics and word problems.
Math topics Gauth lists, from word problems to calculus
The math coverage is specific. It includes math word problems, algebra (real numbers, set theory, logarithms, complex numbers) and functions such as linear, quadratic, exponential and inverse.
Geometry covers plane and solid shapes, lines and planes in space, and transformations. Trigonometry includes the law of sines and the law of cosines. Calculus covers derivatives, integrals and limits, and statistics includes probability and Poisson and normal distributions.
Matrix work and logic, meaning reasoning and proof, are also covered. Beyond math, the developer says the app handles physics, chemistry and biology. It also says human experts are available around the clock for several subjects.
When another study app makes more sense
Gauth is free to install, but it has in-app purchases. The developer points to a paid Gauth Plus plan for unlimited answers.
If you want a plain calculator or an app with no paid tier at all, check the purchase details on the Google Play page first. This entry covers Android only.
