What trackle GmbH does
trackle GmbH is a Bonn-based medical device company founded in 2015 that manufactures the trackleCatch vaginal sensor system (model "Elsa"), a Class IIb CE-certified device under EU MDR for hormone-free contraception and fertility tracking. The product works by continuously measuring core body temperature during sleep and syncing encrypted data via Bluetooth to a companion smartphone app, which combines the temperature readings with user-logged cervical mucus observations to calculate daily fertility status according to the strict symptothermal method (Sensiplan/NFP) algorithm. The company reports a Pearl Index of 0.4 with perfect use and >99.6% contraceptive safety, and the symptothermal method has been recommended by the German Society for Gynecology and Obstetrics (DGGG) S3 guidelines since 2024.
The company's business model blends one-time hardware sales of the trackleCatch sensor (with a 30-month warranty) with a recurring subscription offering called trackleGo (Flex-Abo), which includes a 6-month trial period that converts to a 24-month term if not cancelled. Distribution is multi-channel: direct-to-consumer e-commerce via shop.trackle.de, physical retail through dm drogeriemarkt, pharmacy partners (DocMorris, Shop Apotheke, Aliva Apotheke), and third-party marketplaces (Amazon, Otto), with product shipping to seven European countries (Germany, Austria, Italy, Spain, Netherlands, Luxembourg) and localized content in eight languages. The company also operates a Fachkreise program targeting gynecologists, NFP/Sensiplan consultants, and sexual health educators to drive professional recommendations.
Operationally, trackle employs 1-10 people, is privately held with no institutional investors disclosed beyond small accelerator and angel engagements (STARTPLATZ, VentureOut, DIGITALHUB.DE, Cross Atlantic Angels), and is led by founder Katrin Reuter with Maxim Loick serving in a chief technology/experience officer capacity. The company invests heavily in content marketing, free webinars, educational e-books, and certified NFP consultant endorsements, and has received media coverage in major German outlets (Brigitte, FAZ, Handelsblatt, Vogue, Zeit Online) and a "Testsieger" award from Kaufkompass (F.A.Z.-Verlag). Revenue is not publicly disclosed.

trackle GmbH product offering
Product offeringCore offering
trackle GmbH sells a Class IIb certified medical device system for hormone-free contraception and fertility tracking. The trackleCatch sensor is worn overnight inside the body to continuously measure core body temperature during sleep; data is synced via Bluetooth to the trackle app in the morning, where it is combined with manually logged cervical mucus observations and processed using a symptothermal method (Sensiplan/NFP) algorithm to display daily fertility status. The device is sold as a one-time hardware purchase or via the Flex-Abo (trackleGo) monthly subscription, supported by educational add-ons such as the Zervixschleimkurs.
Product overview
trackle GmbH offers a hormone-free contraception and fertility tracking system consisting of the trackleCatch sensorsystem (vaginal temperature sensor model Elsa), the companion trackle smartphone app, and the trackleGo subscription plan. Users wear the sensor overnight to measure core body temperature continuously, sync data to the app via Bluetooth in the morning, and manually log cervical mucus observations. The app calculates daily fertility status using the symptothermal method (STM). The product portfolio also includes paid educational add-ons — the Zervixschleimkurs (cervical mucus observation course), the Pille absetzen guide (pill discontinuation guide), and a free onboarding course — as well as the trackle Ausflussbuch e-book.

trackle GmbH competitors and assessment
Company assessmentDirect peers
- Tempdrop: Tempdrop is an arm-worn nocturnal temperature sensor paired with an app for fertility tracking. While the form factor differs (bracelet vs. vaginal sensor), it competes in the same continuous-temperature, sleep-measuring, app-driven fertility tracking category.
- Daysy (Valley Electronics): Daysy is a German temperature-based cycle computer using a daily oral thermometer, comparable to trackle's vaginal sensor and symptothermal method. It targets the same DACH audience seeking hormone-free contraception and represents the closest direct hardware competitor in the German-speaking market.
- Ava Science: Ava produces a fertility tracking bracelet that captures multiple physiological parameters overnight and is marketed primarily for conception rather than contraception. It addresses the same use case as trackle's trackleGo (conception/family planning) with a less invasive wearable format.
- Natural Cycles: Natural Cycles is a Swedish-origin, EU-regulated digital contraception app/device that uses basal body temperature to determine fertility. It is the most direct global competitor to trackle in hormone-free contraception, holding similar regulatory credentials and serving women seeking NFP alternatives.
- Lady-Comp / Baby-Comp (Valley Electronics): Lady-Comp and Baby-Comp are established Valley Electronics cycle computers using oral morning temperature measurement, marketed for contraception and conception. They are DACH-market predecessors/alternatives to trackle in the same symptothermal hormone-free category.
Broad incumbents
- Flo Health: Flo is the world's most-downloaded period/cycle tracking app with a massive global user base. It addresses overlapping consumer needs (cycle insight, fertility awareness, hormonal health education) but lacks trackle's medical-device certification and hardware component.
- Clue (BioWink): Clue is one of the largest cycle and period tracking apps globally, focused on fertility awareness rather than certified contraception. It serves a similar end-user (women tracking cycles/hormone health) but is a software-only competitor without a hardware or certified-contraception positioning.
- Elvie: Elvie makes connected female health hardware (e.g., pelvic floor trainers, breast pumps) targeting women's health and wellness via premium consumer electronics. It shares the connected-female-health-device positioning with trackle but operates in adjacent categories rather than contraception.
- Fitbit (Google): Fitbit offers cycle-tracking features in its consumer wearables and could expand into continuous temperature monitoring. As a high-volume mainstream health wearable brand, it represents the platform competition that could compress niche FemTech hardware players.
- Oura: Oura is a leading consumer health ring with increasing women's health and cycle-tracking capabilities added through software. While not a contraception device, it represents an adjacent connected-wearable platform that could absorb fertility tracking functionality and compete for the same health-conscious female consumer.
