Size Before You Buy
Before purchasing a femometer ring, we recommend purchasing a sizing kit to determine the best size for your finger. It’s the ideal way to find the perfect size.

Femometer Ring sizes are different than standard ring sizes. The Femometer Ring Sizing Kit is the best way to ensure a comfortable and accurate experience.
Purchase the Sizing Kit
Size first, Femometer Ring is available in 4 sizes from 6-9.
Easy to wear, everywhere
Stay present without notifications on your wrist. Check the Femometer App when you want to.
Why should I use the sizing kit before ordering my Femometer smart ring?
The sizing kit ensures a perfect fit for both comfort and accurate health tracking. An improper fit may cause discomfort or interfere with sensor contact, leading to unreliable data.
How does the sizing kit help me choose the right ring size?
Test different sizes for 24+ hours (including during sleep/exercise) to account for natural finger swelling. The ideal fit feels snug but allows slight movement and won’t leave pressure marks.
Why can’t I use my regular ring size for the Femometer smart ring?
Unlike traditional rings, the smart ring has built-in sensors along the inner wall, requiring precise contact with your skin. The sizing kit accounts for this unique design, ensuring the sensors align correctly.
Why Ring Sizing Kit: femometer ring sizes are different from standard ring sizes. That’s why we offer size kits for you before you buy. femometer Ring is available in sizes 6-9.
How It Should Fit: Please hold the measuring instrument tightly against the base of your finger and make sure it not rotate freely. We recommend wearing your ring sizer for at least 24 hours to confirm your best fit.
Best Accuracy Recommend: When wearing the ring, please make sure the engraved numbers face the back of your hand. For best accuracy, we recommend wearing the femometer ring on your index, middle and ring fingers.
Get Your Ring: After you’ve precisely determined your exact size using our sizing kit, head over to Amazon to order your femometer ring.
The femometer sizing kit is made of high-quality plastic, the femometer ring has a different material composition. While the outer of the femometer ring is made of oxidized ceramic, and the inner is also coated with a scratch-resistant layer to promise excellent quality and durability.

Easy BBT and sleep tracking
I have been using the ring for months now. I wanted to be able to give an honest review. The ring is tight but not uncomfortable. I can wear it on either the ring or middle finger. It has successfully tracked and showed the difference in BBT throughout my cycle. This is helpful since I’m trying to conceive.When I was having issues customer service quickly responded and helped me. The app for the ring is free and makes tracking easier. I would definitely recommend this ring for tracking BBT as well as sleep.

Don’t buy this!
Don’t waste your time! I have had two faulty rings now and have officially requested my money back! I was so excited for this ring and now that I have had two stop working out of no where after having them for less than 2 weeks annoys me! The first one stopped working after 6 days and the second one after 10. Kept on on charging it and everything and then stopped working out of no where!

Great for tracking BBT
Overall, I really like the femometer. It saves a lot of time and hassle vs. taking BBT with a thermometer in the morning. I think that for all of the included features that this product is priced extremely reasonably, especially compared to super pricey competitors like the Oura ring. I do find the app a bit difficult to navigate at times and the syncing process is a bit hit or miss on certain mornings. The predictions are growing more and more accurate with each cycle, however, and I enjoy having this device in my TTC toolbox. The battery lasts about a week and it fits TTS compared to my other rings. I would recommend this product.

Buy this first.
Definitely get this before ordering a ring. They’re not the same size as normal rings so it’s saved time and trouble.

Great product for the price
Absolutely great product with reasonable pricing! The app is easy to work with, and it automatically sinks your BBT so you can track your body temperature along with menstrual cycle! Also great if you’re needing fertility and conceiving info

Great for BBT
I’ve been very happy with this ring! I use it to track BBT to help with cycle interpretation, specifically TTA pregnancy. The app works well, the charge lasts at least a week, and the daily sync of the BBT is quick. The ring fits well and is durable. It also tracks sleep. I find this ring much easier to wear at night than a smartwatch. If you are on the fence about buying it, I say do it. I’ve been nothing but pleased with the app and performance of the ring.
