breathe ilo

Cycle tracking, as easy as breathing.

breathe ilo is a system of a handheld device and an App, designed to support women who want to observe their menstrual cycle or are trying to conceive.

The system combines a handheld device with an app to analyze natural CO₂ changes in exhaled breath. Hormonal fluctuations across the cycle influence breathing patterns. breathe ilo uses infrared-based CO₂ measurement technology to translate these cyclical changes into cycle phase information in the app.

How it works with device:
• Connect the device
• Breathe for 60 seconds daily
• View guidance related to your fertile window

App-only use:
• Period tracking
• Symptom logging
• Cycle monitoring

Easy everyday use
No temperature tracking. No urine testing. No cervical mucus monitoring.

breathe ilo is not a contraceptive and does not replace medical advice.
