SnapBio vs Gauth: which is better for biology?
Gauth is an AI homework helper that solves questions from a photo. It is best known for maths and also covers other subjects, including science. SnapBio is an iPhone app built only for biology. Here's how they compare.
We make SnapBio, so we're biased. We've tried to be fair: each entry says who it's best for, including when that isn't us. Facts about other apps come from their official websites and public listings and were checked October 2026.
If most of your homework is maths, Gauth is a sensible all-rounder. If biology is the subject you struggle with, SnapBio is designed around it.
