What Tempdrop does

Tempdrop Ltd. is an Israel-based, privately held consumer health technology company founded in 2014 that designs and sells a wearable basal body temperature (BBT) sensor paired with a smartphone application for fertility tracking. The Tempdrop Gen2 sensor is worn on the upper arm during sleep and continuously records body temperature and motion throughout the night; a proprietary, patented Active Temperature-Noise Cancellation (ATNC) algorithm filters environmental disturbances and learns each user's individual nightly and monthly temperature patterns to derive accurate BBT readings without requiring consistent wake times. This technical approach directly addresses the primary failure mode of traditional oral BBT thermometry for women with irregular sleep, shift work, postpartum patterns, or hormonal conditions such as PCOS and endometriosis. The system is FDA Registered, CE Marked, and HSA/FSA eligible.

Tempdrop monetizes primarily through direct-to-consumer e-commerce at tempdrop.com, selling the Gen2 sensor at $149 (with a recurring $9.99/month or $89.99/year Premium app subscription), plus accessory armbands ($29), a VIP Care Package ($25) extending the satisfaction guarantee and warranty, and an optional annual renewable insurance product ($45–89). The go-to-market motion is product-led growth: a free basic charting app drives adoption, two months of free Premium are bundled at hardware purchase, and a Typeform quiz funnel, affiliate program (up to 15% commission), influencer collaborations, and earned media (Forbes, The New York Post, Parents.com) convert and retain users. Exclusive regional distributors serve France, Poland, the UK/Ireland, the Czech Republic/Slovakia, and Hungary, with direct shipping to the US, Israel, and Australia.

The company's served market spans women trying to conceive, practitioners of fertility awareness methods, postpartum and breastfeeding women, women with hormonal health conditions, and perimenopausal users, supplemented by a network of endorsing clinicians and certified fertility awareness educators. Apple Health (HealthKit) integration, an approved third-party app ecosystem, and the recently launched 'Conceive with Confidence' expert-coaching bundle extend the platform beyond pure hardware into services and interoperability. Headcount sits in the 11–50 range with no disclosed external funding.

Core offering

Tempdrop designs, manufactures, and sells a wearable upper-arm basal body temperature (BBT) sensor that continuously monitors body temperature during sleep, paired with a mobile charting app for fertility and menstrual cycle tracking. The proprietary Active Temperature-Noise Cancellation algorithm filters environmental disturbances and learns individual user patterns to deliver accurate ovulation and fertile window insights without requiring consistent wake times. The product line includes the Tempdrop 2.0 sensor, a free and premium app, fabric armbands, insurance protection, and the Conceive with Confidence bundle.

Product overview

Tempdrop offers a fertility tracking ecosystem centered on a wearable basal body temperature (BBT) sensor (Tempdrop 2.0) paired with a mobile charting app. The core offering consists of the Tempdrop 2.0 Advanced Fertility Monitor—a wearable sensor worn on the upper arm during sleep that continuously tracks body temperature through the night—and the accompanying Tempdrop App available in free and premium tiers. Tempdrop Premium subscription adds ovulation insights, sleep quality tracking, Tempdrop Academy education, and advanced calendar forecasts. The product line extends to accessories (fabric armbands), insurance protection plans, VIP care packages with satisfaction guarantees, and the Conceive with Confidence bundle offering expert-led conception support. The system uses a patented Active Temperature-Noise Cancellation algorithm to filter overnight temperature readings and learn individual user patterns.

Direct peers

• Natural Cycles: Natural Cycles is an FDA-cleared contraceptive app that uses BBT data to identify fertile windows. It is the closest regulated competitor for women who rely on temperature data for either conception or contraception, and competes with Tempdrop Premium on the algorithm-driven ovulation insight layer.
• Ava: Ava is a wrist-worn fertility tracker that combines overnight temperature with multiple physiological signals. It targets the same TTC and cycle-aware female customer as Tempdrop and competes directly on the wearable-fertility-monitoring value proposition.
• iFertracker: iFertracker is a wearable BBT sensor that continuously measures overnight temperature, very similar in form factor and value proposition to Tempdrop. It competes head-to-head with Tempdrop on continuous monitoring, app-based charting, and the TTC use case.
• Valley Electronics (Daysy): Daysy is a direct competitor in the consumer BBT-fertility tracker category, offering a smart oral thermometer paired with an app for cycle charting. Both companies serve the same TTC and fertility-awareness user with a connected temperature-tracking solution, competing on accuracy claims, app insights, and subscription pricing.
• Yono Labs: Yono Labs makes an in-ear wearable BBT sensor for overnight temperature tracking. It overlaps directly with Tempdrop's continuous overnight temperature monitoring approach and competes for the same TTC and FAM user looking for a wearable alternative to oral thermometry.

Broad incumbents

• Clue: Clue is one of the most widely used cycle-tracking apps globally, focused on period, fertility, and symptom tracking. While it does not sell hardware, it competes with Tempdrop Premium on cycle prediction, ovulation insights, and as a default cycle-awareness tool for women.
• Flo Health: Flo is a leading AI-driven period, ovulation, and pregnancy app with a large global user base. It competes with Tempdrop on the cycle-tracking and TTC engagement layer, including premium features that overlap with Tempdrop Premium insights and forecasts.
• Apple (Apple Watch + HealthKit): Apple's smartwatch and HealthKit platform increasingly support cycle tracking, wrist temperature trends, and integrations with third-party fertility apps like Tempdrop. As a platform incumbent, Apple both competes with and enables Tempdrop, but its scale and ecosystem make it the most consequential adjacent player in the space.
• Oura: Oura is an established smart-ring wearable with a broad consumer health and sleep-tracking positioning. With its female-health temperature features and integration with cycle-tracking apps, Oura is an incumbent that increasingly overlaps with Tempdrop's overnight-temperature and cycle-insight value proposition.

Emerging players

• Femometer: Femometer offers smart BBT thermometers that pair with a fertility charting app at lower price points. It targets a similar TTC user with a more accessible, oral-thermometer-based product, and competes with Tempdrop primarily on price and entry-level convenience.
