How can we help?

Take or choose a photo of a biology question and crop it to the part you need. SnapBio reads the question with AI and gives you the answer, then a step-by-step explanation.

Most school and introductory college biology: cells, genetics, ecology, infection, photosynthesis, respiration, the human body, plants, evolution and more.

SnapBio is free to download and includes three free solves per day. Pro includes unlimited solves, simpler explanations, quizzes and flashcards. Plans and prices are shown in the app before you purchase.

For best results, write clearly and take photos in good lighting. Make sure your handwriting is legible and the paper is flat. The app works best with printed text, but it can recognize neat handwriting as well.

Open the Settings app on your iPhone, tap your name, then Subscriptions. Find SnapBio and tap Cancel Subscription. Your subscription stays active until the end of the current billing period.

An internet connection is required to generate answers, simpler explanations and new practice sets. Previously saved content is kept in your notebook on your device.

SnapBio uses AI, which can make mistakes. Check the steps against your class notes or textbook, and use the explanation to support your own understanding. Correct answers and grades are not guaranteed.
