CellWalk puts a living cell in your hands and on your desk. Zoom from a whole cell down to the atoms in DNA. Explore a cell modeled protein by protein from real structures discovered by scientists. Start your journey with Ako, an AI tutor that helps you understand what you see. Built for students, teachers and anyone curious about how life works at the molecular scale. 2025 Apple Design Award finalist. EXPLORE A REAL CELL Zoom from a whole Mycoplasma cell down to single atoms. Thousands of proteins, DNA and RNA, ribosomes and membranes, rendered from published scientific data. Tap any molecule to learn what it is and what it does. Tap any term for an explanation at your level, written on your device with Apple Intelligence. Place molecular scenes in your space with augmented reality on compatible iPhone and iPad devices. LEARN WITH AKO Ako helps you build understanding through questions. It brings molecular structures into view, invites you to look closer and explain what you notice, then builds on your answers to help you make connections. Socratic learning, one discovery at a time. Type or dictate. Ask anything about what’s on screen or in your space. Your Ako lessons, your progress in them and what Ako has learned about you stay with you: on your device and, if you use iCloud, in your own iCloud. Get more of Ako with CellWalk Pro. GUIDED TOURS Start your journey with The Molecular Design of Life, a complete tour of the Mycoplasma cell made with Dr. David Goodsell. Each tour includes a guided narration, free explore mode and Ako practice lessons to test your understanding. CellWalk Pro adds more guided tours and lessons with an expanded library of cells and organisms. Explore the incredible molecular machines that power neurons and thought, or dive into the architecture of a virus like HIV. LEARN BY DOING Step into the Central Dogma of Biology with a hands-on interactive lesson on the all new Learning Path. Learn how the instructions in DNA are read and translated into the proteins that build and sustain your cells. WHAT’S FREE Explore The Molecular Design of Life tour and its accompanying Ako lesson and explore modes, and try the “What is a Protein?” interactive lesson on the Learning Path. You can also ask Ako in-depth questions with a free daily allowance. CELLWALK PRO Unlock all other guided tours and their accompanying Ako lessons, a larger daily question allowance and longer answers from Ako. Choose a monthly or annual auto-renewing subscription. One subscription covers iPhone, iPad and Mac. ASK FROM ANYWHERE Say “Ask CellWalk a biology question” and Siri answers from CellWalk’s own content without opening the app. “Continue my lesson in CellWalk” picks up where you left off. On iPhone and iPad, use Visual Intelligence on a textbook diagram, choose Search CellWalk with an Image, and tap a match to open that tour, lesson or molecule. HOW THE AI WORKS Ako is built with the Foundation Models framework. Where Apple Intelligence is available, it answers on Private Cloud Compute, and the on-device model explains the terms you tap. OpenAI, a third-party AI service, plans lessons and answers when Apple Intelligence isn’t available on your device or in your region. The app asks your permission before sending your first question. You can change that permission under Account → Privacy. CellWalk doesn’t require a separate CellWalk account, and AI requests aren’t tied to your name. Find details under Account → Privacy → About CellWalk & AI. Apple Intelligence features require iPhone 15 Pro or later, an iPad with M1 or A17 Pro or later, or a Mac with Apple silicon.
