Meet your 24/7 health companion

The femometer Smart Ring Gen2 Ceramic blends a refined, minimal look with a powerful health sensor suite that stays with you from morning to night. At a barely-there 3.3 g, and a slim 2.7 mm profile, it’s designed to be worn around the clock. A premium ceramic exterior paired with an aluminum core delivers durability for everyday life, while continuous heart rate monitoring and HRV tracking feed data into the lifetime free femometer app, helping you spot patterns and trends over time without extra effort.

Sleep with clarity

Sleep is treated as a part of your daily rhythm: it tracks Deep, Light, and REM stages, and it monitors blood oxygen levels as you rest. A detailed sleep score pairs with actionable, personalized recommendations, so you can evaluate how your nights relate to daytime energy and mood.

Cycle tracking that fits your rhythm

The Gen2 uses revolutionary BBT technology, delivering 1,400+ nightly temperature measurements to refine cycle predictions and ovulation detection. It sits inside the trusted femometer ecosystem, which resonates with a large community of users who value long-term data history and visibility into cycles.

Designed for daily life

Durability meets comfort: the 2.7 mm profile hides an aluminum core beneath a scratch-resistant ceramic finish. The ring is water resistant to 100 m, making it suitable for daily wear, workouts, showers, and more. Begin with the sizing kit to ensure a precise fit that feels natural on your finger.

Power, simplicity, and compatibility

Expect up to 35 days of battery life, aided by a quick charging case that stores five full charges. When paired with the femometer app, you receive a lifetime subscription that works across iOS and Android. Regular firmware updates keep the experience fresh, secure, and capable of growing with your needs.
