Your Health, Revealed in Living Color
Chroma creates phone cases with embedded microfluidic channels that perform instant vitamin D and B12 tests using a tiny finger-prick blood sample. The chemical reaction creates a unique color pattern on your case like a painting — livestream the reveal to friends as your health becomes a shareable moment.
You prick your finger, touch the sample port on your phone case, and watch as beautiful swirling colors bloom across the back of your device in real-time. A deep blue indicates you're vitamin D deficient, while vibrant orange means you're optimized. Tap 'Share' and your Chroma color art appears on your friends' lockscreens as a living health status update.
