Trackle is a hormone-free, digital fertility tracker that uses a sensor to continuously measure a woman's core body temperature during sleep to determine fertile and infertile days. It combines this data with user-entered information like cervical mucus in a smartphone app to provide reliable cycle tracking.

Trackle checks your body’s temperature from the inside, giving you more accurate and consistent readings than skin-based methods.
It’s a certified medical device that detects even tiny temperature changes—helping you reliably identify your fertile window.
Whether you're trying to conceive or avoid pregnancy naturally, Trackle supports you with a trusted method backed by research and proven results.

Trackle automatically transmits the temperature data to an app once you have taken it out of your body. It eliminates the need to manually enter readings and reducing the chance of data entry errors. It simplifies tracking by only requiring you to input symptoms into the app in the morning.

The app uses a validated algorithm to evaluate your cycle and identify fertile days based on your individual data.
It accounts for factors like irregularities in sleep cycles, making it a suitable option for women who have difficulty with consistent temperature taking.
Over time, the system's forecasts become more accurate as it learns your unique cycle patterns.
