Health Awareness Should Be Effortless
We built Circadify so anyone with a phone can check their vital signs — free, fast, and private
Why We Built This
Checking your vital signs used to require a trip to the doctor, an expensive wearable, or a drawer full of gadgets. We thought that was an unnecessary barrier between people and their own health.
Circadify started with a question: what if the phone you already carry could tell you your heart rate, stress level, and blood oxygen — without buying anything new?
Using a technology called remote photoplethysmography, we turned that idea into an app. Your camera reads the invisible signals your body is already broadcasting. We just made them visible.
Our Mission
To give every person instant, free access to their vital signs using the phone they already own. No wearables, no cost, no barriers — just awareness of what your body is telling you.
What We Stand For
Free to Try, Always
We believe cost should never stop someone from checking in on their health. Core vital signs scanning is free and always will be.
Your Data, Your Phone
We process everything locally. Your biometric data never leaves your device because we believe privacy is a right, not a feature.
Simplicity Over Complexity
If it takes more than 30 seconds or requires reading a manual, we've failed. Circadify should be as easy as taking a photo.
Honesty About What We Are
Circadify is a wellness tool, not a medical device. We help you build health awareness and track trends — and we'll always be upfront about that.
