Product details

Overview

The Femometer Ring Gen1 is a discreet, wearable ring you wear on your finger throughout the day. Real-time temperature readings feed into the companion app, which automatically syncs data and translates numbers into clear fertility charts. Whether you are planning for pregnancy or simply aiming for cycle awareness, this ring offers a practical, low-friction way to capture your body’s signals while you go about your routine.

Beyond fertility tracking, Gen1 includes a sleep analysis feature. The updated algorithm maps nightly stages, assigns a score, and provides actionable notes to help you understand patterns over time. Combined with temperature data, you may notice how daily rhythms relate to cycle changes, providing a non-medical, observational perspective on your body’s signals.

Size first, comfort always

To ensure the best data and comfort, start with the sizing kit before selecting a size. A precise fit improves sensor contact and data reliability as you move through everyday activities. The ring’s profile is slim, at 2.7 mm thickness, while the ceramic exterior and aluminum core balance a premium feel with durability.

  • Size Before You Buy: use the sizing kit to find a comfortable fit and reliable readings.
  • How to download the app: Android users should search for Femometer Connect; iOS users should search for Femometer.
  • Wear the ring to monitor temperature in real time, with automatic app synchronization.
  • Data is presented as tailored fertility charts and cycle insights within the app.
  • The ring is designed to be waterproof and durable for daily wear.

How the app supports you

The app serves as a personal tracking hub, translating temperature data into easy-to-read visuals. Review a fertility forecast, keep an eye on your period, and observe changes in basal body temperature across days and weeks. Sleep scores and insights are designed for quick scanning, helping you spot trends at a glance.

  • Real-time fertility tracking with synced charts and cycle predictions.
  • Sleep insights that help you understand rest quality and its daily impact.
  • Period tracking, reminders, and an overview of cycle health.
  • Rechargeable design and waterproof wear support long-term use.

Everyday possibilities

Imagine mornings with a concise view of yesterday’s sleep quality, today’s temperature, and a heads-up about the upcoming likely fertile window. The Gen1 ring is designed to feel subtle on your finger, so you can wear it during workouts, work, and evenings without disruption. With ongoing data in the app, you gain a clearer, observational look at patterns and personal rhythm, presented as possibilities rather than promises.
