## What is CellWalk?

Zoom from whole cells to molecular detail, and tap highlighted terms for clear, contextual explanations—powered by Apple Intelligence and Foundation Models running entirely on your device. Built to help students explore cell biology, and designed for learning.

What’s new in 1.1
• “Tap-to-Learn” on-device AI definitions and concept chains.
• Redesigned for iOS 26 with Liquid Glass.

Concept Chains (Tap-to-Learn): Tap any term to get an explanation tailored to your level (Beginner, High School, Researcher). Keep tapping to follow a coherent chain—each step builds on your previous taps. Powered on-device by Apple Intelligence and Foundation Models, grounded in CellWalk’s scientific datasets.

Key Features
• Multi-Level Explanations: Switch between Beginner, High School, and Researcher levels to get the right depth for your background.
• Interactive Learning (On-Device AI): Conversational definitions grounded in CellWalk’s scientific datasets—no cloud required.
• Touch-First Exploration: Pinch, pan, and orbit smoothly across scales, from cell architecture to molecular structure.
• High-Fidelity Visuals: Metal-accelerated rendering for crisp, responsive scenes.
• Expert-Guided Intro: Start with a free introduction to Mycoplasma bacteria narrated by Dr. David Goodsell.
• Rich Scientific Content: Thousands of modeled proteins with concise, accurate descriptions.
• Elegant UI: Refined browser with Liquid Glass for fast, focused navigation.
• Ideal for students, educators, and anyone curious about how cells work—delivered with clarity and scientific rigor.

### 5/5 — Amazing detail

*2026-02-06, version 2.1.1*

Very cool app!

### 5/5 — Life

*2025-11-22, version 2.1.1*

Beautiful

### 2/5 — Cool visuals, but the explanations are rough

*2025-11-15, version 1.1.2*

Be skeptical of the information provided as they are misleading. ATP synthase is described backwards, it makes ATP using proton flow, not the other way around. Great concept but the biology needs a fact check

### 4/5 — More Content

*2025-09-30, version 1.1.1*

Great app, but they should make more cells. It would be interesting to see something like this but with computers instead of cells.

### 5/5 — CellWalk’s Brain Cell

*2025-09-20, version 1.1*

That seems like comes from the bacteria brains that have a very strong immune system that can fight against viruses cells in the brain.

### 5/5 — Stunning and informative

*2025-09-15, version v1.0.3*

For a non-scientist, it is breathtaking to see inside a human cell with such beauty, clarity and resolution 👏🏼👏🏼👏🏼

### 5/5 — Beautiful work.

*2025-09-03, version v1.0.3*

Simply marvellous to hold the functions of life in the palm of your hand and get really close.

### 5/5 — Really cool app

*2025-08-07, version v1.0.3*

The best cell exploration I’ve seen on my iPhone

### 5/5 — Has great potential

*2025-08-01, version v1.0.3*

Amazing work. Please keep developing further, keeping the scale of the molecules accurate

### 5/5 — Beautiful Visualizations

*2025-07-13, version v1.0.3*

My undergrad is in biochemistry, graduate degrees in microbiology/ biotechnology, and I’m a self-taught software engineer. This is such an awesome resource for visualizing cellular morphology (structure). It shows how dense cells are compared to traditional textbook depictions. 

I hope in the not too distant future we can get an update that depicts a minimal eukaryotic cell. The smallest I believe is about 25x as many base pairs of DNA.
