Beurer OT 30 Ovulation Checking Thermometer with Bluetooth & App Sync

Plan Ahead with Precision — Know Your Most Fertile Days

Tracking your cycle just got smarter. This basal body thermometer measures your temperature with clinical-grade precision and pairs with a dedicated cycle-tracking app over Bluetooth, turning small daily readings into a clear picture of your fertile window. Whether you're planning a pregnancy or simply want to understand your body's natural rhythm, it takes the guesswork out of the process.

A flexible, gentle measuring tip allows for both oral and vaginal use, while a fast ~3-minute measurement cycle and a clear two-decimal display mean you get precise, easy-to-read results every morning. Once the reading is complete, an illuminated ring and acoustic signal confirm it instantly, and your data transfers wirelessly to the app for automatic charting — no manual logging required.

Built for daily use, it's fully waterproof, easy to disinfect, and stores up to 30 past measurements on-device, so you always have a reliable record even before syncing. Simple, hygienic, and accurate — everything you need for confident cycle tracking.
