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. Read more

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 Read more

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! Read more

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. Read more

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.

I bought this to help track my sleep but it has become so much more than that. The app syncs with my apple health so I have more data. I have been using it for 3 months now and I love the price point, the fact that the charge lasts so long and ease of use. Read more
