breathe ilo – your cycle tracker

breathe ilo is a breath analysis device and the easiest way to accurately predict your fertile days. It takes just one minute of breathing into the handheld device every day and the breathe ilo app shows you your fertility status. Whether you’re trying to get pregnant or you just want to learn more about your body, breathe ilo offers free access to an extensive library on female health.

The hormones that are produced during the female cycle to start ovulation change the CO2 levels your body releases. Based on your daily CO2 measurement and individual cycle patterns breathe ilo‘s system identifies where you are in your cycle with incredible accuracy. breathe ilo has been tested in studies with cycle lengths of 24-36 days. The breathe ilo app helps to identify and keep track of your symptoms.

The app controls the breathe ilo device, shows your current fertility status and also includes our unique algorithm. This algorithm gets to know each woman individually and supports the CO2 measurement. With daily measurement, our app shows your fertility status and helps you in understanding the progress of your cycle. We have also integrated a digital cycle calendar for you. This allows you to document symptoms, your mood, various aches and pains and many other factors that can occur during your cycle. In combination with the app, breathe ilo can be used regardless of location, and your fertility status is always visible in the app.
