About
Tempdrop is an all-in-one fertility tracking solution that combines a wearable hardware sensor with an intelligent charting app. The sensor is worn on the upper arm during sleep to continuously monitor basal body temperature throughout the night. Data is synced to the Tempdrop smartphone app, where a proprietary smart learning algorithm interprets temperature patterns—even accounting for irregular wake times—to deliver accurate cycle and fertility insights. The app comes in both a free and Premium version. The free tier covers core BBT charting, while Tempdrop Premium unlocks personalized ovulation confirmation, fertility window insights, sleep quality scoring (with deep and light sleep stage tracking), a fertility awareness education program through Tempdrop Academy, and a calendar view with up to 6-month cycle forecasts. Tempdrop is trusted by OB-GYNs, naturopathic doctors, and certified fertility awareness educators worldwide. It is especially valuable for women with irregular sleep schedules or irregular periods—groups underserved by traditional BBT methods. The sensor is completely non-invasive and emits zero radiation during sleep, making it safe for nightly long-term use. Whether users are trying to conceive, practicing natural family planning, or simply wanting to better understand their bodies, Tempdrop provides an accurate, science-backed, and effortless approach to fertility awareness.
