FAQs
How should I wear the smart ring correctly for optimal performance and accurate readings?
To ensure accurate measurements, we recommend wearing the smart ring on your index finger. If you would like to use another finger, ring finger and middle finger can also offer a good performance. The sensor side of the ring should be positioned to meet the palm side of your finger. This placement helps the ring capture precise data for effective health tracking.
Is the Femometer Ring compatible with my smartphone?
Yes, the Femometer Ring seamlessly syncs with the Femometer App, compatible with both iOS and Android devices, ensuring easy access to your fertility data anytime, anywhere.
How long can the ring store my data?
The Femometer Ring stores up to 15 days of data, providing ample time for reviewing and managing your health insights.
What's different between Femometer Ring Gen1 and Ring Gen2?
Femometer Ring Gen1 only tracks basal body temperature, monitoring women's fertility and sleep. Femometer Ring Gen2 expands on this by also tracking heart rate, HRV, and steps, while adding monitoring for heart health, activity, and REM sleep.
