Best of 2026
Stuck on a biology worksheet at 10pm? These are the apps worth having. Some explain a single question, some teach a whole topic, and some help you memorise it for the test.
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.
What matters to you?
Best for: Getting unstuck on a specific biology question
Snap a photo of the question and SnapBio gives you the answer and then short, numbered steps to get there. Answers save to a notebook sorted by topic. Pro adds simpler explanations, quizzes and flashcards.
Best for: Learning a whole topic from scratch
If you've missed a few lessons, Khan Academy's free biology courses are the best way to catch up. Videos and practice questions build up a topic from the basics.
Best for: College students who need textbook solutions
Chegg's library of textbook solutions and expert answers is hard to beat when your course follows a popular US textbook.
Best for: Memorising biology vocabulary
When the test is mostly definitions, Quizlet's flashcard sets and study modes get terms into your head quickly.
Best for: Help across every school subject
Brainly mixes community answers, AI help and paid tutors across all subjects, so it's useful if biology is one of many classes you need help with.
Best for: Quick free look-ups
Point your camera at a question and Lens finds related pages and sometimes an AI explanation. Fast and free, but you'll often need to read around.
Best for: Students who mainly need maths help
Gauth is a strong photo solver for maths that also covers science, which makes it a good all-rounder if maths is your main struggle.
For getting help with a specific biology question, SnapBio is built for exactly that and has a free daily allowance. For learning a topic from scratch, Khan Academy is the best free option. For memorising terms, Quizlet.
It depends on how you use it and your school's rules. Using an app to understand the reasoning and then writing your own answer is studying. Copying answers without understanding them won't help you in the exam.
