Breathe ilo is the first cycle tracker that can determine a woman's fertile days based on breath analysis. The woman experiences a subtle form of hyperventilation, which is attributed to the difference in her breath. The measurement focuses on the CO2 partial pressure, which drops in women 4-5 days before ovulation. Thus, Breathe ilo is the first and only way to detect ovulation in real-time. Additionally, the accompanying Breathe ilo app includes features such as a cycle diary with cycle comparison and symptom tracking. This allows women to use Breathe ilo for conception purposes and natural cycle monitoring.
