With the increasing prevalence of smart health devices, more and more brands are focusing on the personalized needs of specific consumer groups. As a leading smart health technology company in China, Qkeer has always focused on the concept of “precision health” since its inception, committed to creating truly user-centric health products through cutting-edge sensing technology, AI algorithms, and user-friendly design. Leveraging years of technological accumulation in the wearable device field, Qkeer has successfully launched multiple generations of highly acclaimed health monitoring devices and is gradually establishing an innovative product line centered on women’s health.
In 2026 , Qkeer officially launched its new masterpiece—the Gen4-L19, a smart bracelet tailored for modern women’s full-cycle health management. This product not only continues Qkeer’s consistent high precision and stylish design, but also achieves breakthrough upgrades in women’s physiological health, emotional management, and lifestyle support.
01 Product Introduction: Specially designed for women’s health
The Gen4-L19 is not a traditional fitness tracker, but rather a “smart health companion for women” developed by Qkeer in collaboration with gynecologists, nutritionists, and psychologists, based on in-depth analysis of health data from over 100,000 female users. It focuses on women’s health needs throughout their entire lifespan, from puberty to menopause, providing scientific, private, and convenient digital solutions, particularly for core scenarios such as menstrual cycle prediction, ovulation monitoring, stress management, sleep quality, and daily activities.
Whether you’re a working woman, someone trying to conceive, or a young woman focused on your health, Gen4-L19 can be your personal health advisor, helping you better understand your body’s signals and make more informed life decisions.
02 Product Highlights Analysis
- Precise menstrual cycle and ovulation prediction system
Based on Qkeer’s self-developed FemCycle™ AI algorithm, Gen4-L19 can dynamically optimize the prediction model by combining user-input physiological data, heart rate variability (HRV), skin temperature, and sleep patterns. The accuracy of menstrual cycle prediction is over 92%, and it can intelligently identify the ovulation window, providing scientific reference for preparing for pregnancy or contraception.
- Real-time monitoring of mood and stress
Equipped with a built-in high-sensitivity PPG sensor and EDA (electrical skin response) module, it can monitor stress levels and mood fluctuations around the clock. When abnormally high stress is detected, the band will proactively remind the user to perform deep breathing exercises and simultaneously push mindfulness-guided audio to the accompanying app.
- Sleep analysis specifically for women
Unlike general sleep scores, Gen4-L19 introduces the “female hormonal rhythm” dimension to analyze changes in sleep structure before and after menstruation and provide targeted improvement suggestions, such as adjusting sleep time and supplementing magnesium.
- Lightweight and comfortable wearing experience
Featuring a medical-grade liquid silicone strap, it weighs only 18g, is 9.2mm thick, and is IP68 water-resistant, keeping you comfortable and dry even during menstruation or when sweating from exercise. The watch face supports customizable feminine themes, with soft color schemes to express your individuality.
- Privacy and security first design
All health data is stored locally in encrypted form and supports biometric unlocking (fingerprint/face recognition) to ensure sensitive information is not leaked. Qkeer promises never to use user health data for advertising or share it with third parties.
