How your environment
shapes how you feel.
Foundational Health quietly senses light, sound, and temperature, and pairs them with how you feel. So you can see the patterns between your surroundings and your wellbeing.
Built with autistic and neurodivergent people first.
How it works

Install once
It runs quietly in the background. No daily check-ins.

We connect your environment to your wellbeing over time.

What we sense
Three quiet signals
Your phone already carries these sensors. We read them passively and turn them into context you can understand.
Light
Brightness and color temperature from the ambient light sensor.
Sound
Noise levels from the microphone. Never recorded or stored.
Temperature
Ambient warmth from the device temperature sensor.
Everything is processed on your device where possible. Nothing leaves your phone unless you choose to sync. You can delete it all with one tap.
Why Foundational Health
Built with autistic people, first
Sensory differences are part of how many autistic and neurodivergent people experience the world. We start there — because designing for those needs makes the app better for everyone.
Grounded in lived experience
Built from firsthand understanding of sensory sensitivity.

Questions
Frequently asked
Is this a medical device?
No. It helps you notice patterns between your environment and how you feel. It does not diagnose or replace professional advice.
Does it record my conversations?
Never. We only measure sound level, processed on your device. Audio is never recorded, stored, or sent anywhere.
Will it drain my battery?
The app batches sensor reads and uses low-power modes. Typical impact is a few percent per day.
Do I have to be autistic to use it?
No. It is built with autistic and neurodivergent people first, but the insights help anyone who wants to understand their environment.
When will the alpha be available?
A small alpha opens in early 2027, expanding through the year. Join the waitlist for the fastest way in.
