trackle

The trackle cycle app pairs with the trackle temperature sensor to deliver hormone-free fertility tracking based on the symptothermal method. The app shows daily fertility status, marks fertile and infertile days in a cycle calendar, detects ovulation reliably with NFP, and displays a detailed temperature curve alongside entered body signals (cervical mucus, intercourse, disruptive factors).

trackle works by recording core body temperature overnight with a vaginal sensor worn like a tampon. After removal, the sensor transmits measurements to the app for automated evaluation. It’s ideal for women with irregular sleep or lifestyle patterns who want an accurate, research-backed, non‑hormonal fertility awareness method. Note: the app requires the trackle sensor (available at the trackle shop). For medical advice, diagnoses or treatment consult a physician and follow the device instructions for use available at www.trackle.de/ifu.
