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.

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.

Verdict
The clearest difference is review sentiment: CellWalk at 92% against Explain Everything Whiteboard's 48%. CellWalk also leads on rating (4.9 vs 4.6). Explain Everything Whiteboard's advantage is ratings volume (8.9K vs 71) and iOS requirement (17.0 vs 27.0). On price, update cadence, ads and in-app purchases there is nothing between them.
