The Femometer Gen2 Smart Ring is designed as a discreet yet powerful health companion for women who want deeper insights into their daily wellness, sleep quality, and reproductive health. Unlike bulky wearables, this smart ring focuses on comfort, elegance, and precision. Built with a premium ceramic exterior and backed by Femometer’s well-established women’s health ecosystem trusted by over 15 million users worldwide, the Gen2 Smart Ring combines science-backed fertility tracking with modern health monitoring features — all without any monthly subscription fees.
At the core of the Femometer Gen2 Smart Ring is its advanced Basal Body Temperature (BBT) technology. The ring captures over 1,400 temperature measurements each night, allowing it to detect even the slightest hormonal changes. This enables accurate cycle predictions, ovulation tracking, and fertility window insights. For women planning pregnancy or simply wanting to understand their cycle better, this level of precision makes a meaningful difference compared to basic period trackers.
The ring continuously tracks heart rate and Heart Rate Variability (HRV) throughout the day and night. These metrics help users understand stress levels, recovery patterns, and overall cardiovascular health. By syncing seamlessly with the Femometer app, trends are presented in a clear and easy-to-understand format, helping users recognize long-term changes rather than just daily numbers.
Sleep monitoring is another strong area of the Femometer Gen2 Smart Ring. It tracks deep sleep, light sleep, and REM stages, while also monitoring blood oxygen levels during rest. The app generates sleep scores along with personalized suggestions, helping users improve sleep habits and overall recovery. For women balancing busy schedules, this insight can be extremely valuable.
With a thickness of just 2.7mm and weighing around 3.3 to 4 grams, the ring feels almost invisible on the finger. The premium ceramic finish paired with an aluminum core ensures durability without compromising comfort. It is scratch-resistant and water-resistant up to 100 meters, making it suitable for daily wear, workouts, and even swimming.
The Femometer Gen2 Smart Ring stands out with its impressive battery efficiency. A single charge can last up to 7 days, while the charging case can store up to 5 full charges, extending usage up to 35 days without needing a wall socket. This makes it ideal for travel and long-term use without frequent charging interruptions.
Unlike many smart wearables that lock advanced features behind a paywall, Femometer offers a lifetime free subscription to its app. The ring connects via Bluetooth to both Android and iOS devices, providing continuous updates, firmware improvements, and reliable customer support, all included with the purchase.
The Femometer Gen2 Smart Ring is priced at $199.00 in the United States. It is available on Amazon and other major online platforms. Considering the absence of subscription fees and the depth of health and fertility tracking features, the pricing remains competitive within the smart ring category.

The Femometer Gen2 Smart Ring delivers a focused and thoughtful experience, especially for women who prioritize reproductive health alongside general wellness. Its cycle tracking accuracy stands out due to the high-frequency BBT measurements, which feel more medically relevant than algorithm-only predictions. Sleep tracking is detailed and practical, offering insights that can genuinely improve daily routines.
Comfort is another major strength. The slim profile and lightweight design make it easy to wear around the clock, even during sleep. The ceramic build not only looks premium but also holds up well against daily wear and water exposure. While it does not offer GPS or a display like smartwatches, that minimalism feels intentional rather than limiting.
The Femometer app complements the hardware well, presenting complex health data in a clear and supportive way. For users who want health insights without ongoing subscription costs, this ring offers long-term value and peace of mind.
If your priority is understanding your menstrual cycle, fertility, sleep quality, and overall health without wearing a bulky smartwatch, the Femometer Gen2 Smart Ring is a strong choice. It is especially suitable for women who want clinically relevant insights, long battery life, and a subscription-free experience. However, if you are looking for advanced fitness metrics or GPS-based activity tracking, a smartwatch may be a better fit.

Its strength lies in accurate cycle monitoring, meaningful sleep insights, and stress tracking, all wrapped in a discreet and durable design.
