Understanding Brain Health Through the Eyes
We are developing a smartphone app that analyses pupil movements to help detect early signs of memory and brain health changes — using just the camera in your pocket.
What does our app actually do?
- You hold your phone up and look at the screen for a few seconds.
- The camera watches how your pupils change size in response to light.
- Our system looks for patterns that researchers link to early brain health changes.
- You receive a simple result — and a note on whether the reading was reliable.
Just Your Smartphone
No special equipment needed. Our app uses the camera you already have to gently measure your pupil size and how it responds to light.
Your Eyes Tell a Story
Tiny changes in how your pupils react can be early signals of brain health changes — often years before other symptoms appear.
Research-Backed Technology
We are actively studying our measurements across different phones, lighting conditions, and people to make sure results are reliable.
Privacy First
Images are processed directly on your phone. Only the measurement numbers — not your photos — are shared with our platform.
Research & Clinical Validation
We are currently testing our technology across different smartphones, lighting conditions, and patient groups. Our research focuses on two key questions:
- 1Can a smartphone camera measure pupil responses accurately?
- 2Can these measurements help spot early signs of neurological or mental health changes?
Important to know
At this stage, our results cannot confirm or rule out MCI, Alzheimer's disease, depression, PTSD, or any other medical condition. Always speak with your doctor about any health concerns.
Our mission is to turn a simple smartphone into a tool that may help people notice changes in their brain health earlier — when taking action could make a real difference.
