One breath. Three signals.
Three independent semiconductor sensors. One brushed aluminum body. The full chemistry of how today is going.
Most breath devices measure one thing. Respyr measures three.
Three molecules. Three different stories your body is telling right now.
How you're burning energy.
Acetone rises on your breath when fat oxidation rises. The sensor reads it directly — no glucose proxy, no calorie math.
How hard your body is working.
Endogenous ethanol reflects cellular strain. Surfaces the workload that HRV and resting heart rate can't see.
How well today's meals landed.
Hydrogen reflects gut microbial activity. Tells you which foods your body processed cleanly — and which caused strain.
A reading takes eleven seconds.
No fasting. No needles. No patches. Power on, breathe in, breathe out — the result is in your phone before you put the device down.
Active reading time. Result in the app within 60 seconds.
Your breath is more than air. Start reading what it means.
