Easy use
I love this ring. The color combination gives it a feminine look. It is very comfortable and light weight. The free app is easy to use and informative. My cycle tracking and predictions are accurate. The batter life is super with charging during showers. The connectivity and speed of sync is great. This is a great functioning ring!

amazing product!!
loooove this product so much! my femometer has changed the game for me when it comes to tracking my cycle and other health data. it is very easy to use and is so accurate! typically, for biometric rings it is advised to wait at least 60 days after purchase for accurate female data, however, my femometer has been accurate since the very start! that impressed me right off the bat. it holds a charge for up to 4-5 days and then when you put it in the charging case it charges fully within a couple hours! i love how slim the ring is. it is very comfortable and most of the time i barely even notice that i’m wearing it. i love that there is no app subscription. i would 100% recommend this to any woman who wants to track their cycles or even just their sleep/health data.

Should I be worried?
So far I absolutely do love the ring! I wear it on my middle finger and grounded the sizing was a little weird overly I’m satisfied with it. But yesterday, the skin of it I guess you can call it begin to peel off I had to use super glue what a dry a little and then put it back in place. Overall though everything is still working fine the charge life is all that great but yeah!. Sleep tracking is very insightful and I would say that it’s the connectivity it can be slow at times but it works. Overall I want to say it’s pretty accurate though I’m worried about the durability.
Love the shoes. Really comfy to wear. –
Love My Ring!
Love my ring. Been using this every night except when it needs charging. Battery needs charging when it’s under 20% otherwise it may not track your performance or sleep properly.

Cheap quality not worth the price tag
If I could give a zero I would. I had this ring for a month literally and the outside ring cracked, I don’t do any heavy lifting or anything with it on. Then I went to take it off and the whole outer portion just came off leaving the inner portion of the ring still on my finger. It also doesn’t do anything unless you constantly sync it. So in order for it to even register your bbt you have to go into the app everyday every morning and the whole point in buying this was so that I wouldn’t have to go into an app and input this stuff. Also the battery is terrible last 3 days at the most. Don’t waste your money it’s not worth it. Just buy and Oura ring…

Great health tracking/ fertility tracking
Great product created by great people. Truly no subscription health tracking. Femometer is quick to discover faults and send out updates to resolve them without you needing to buy a new ring. I had the pleasure of being able to talk with them about my ideas and changes I would like to see as a customer and they were super receptive and encouraged me continue reaching out with any questions I might have. Very comfortable to wear and over all great product for a great price!

First one didn’t last a year. Second didn’t even last 2 months
I purchased my first ring back in May. It was working great and I loved it! It tracked everything perfectly, and it tracked everything I wanted. The battery worked fine for a while, then I noticed it needed to be charged almost every other day. In October I noticed a crack along the top of the ring, this was confusing because I was never rough with it. It worked for a few weeks after that and then suddenly stopped working, wouldn’t charge. I reached out and customer service was great and even sent me a replacement. The replacement they sent me came mid November. Within the first week I had trouble with charging. Eventually I fixed it by switching the charging port out with a different one. This worked until December 22nd. I reached out again to customer service after the holidays and they told me there was nothing they could do. They ended up offering me a refund which I took, but if I were being honest.. while this ring does have great features.. looks sleek, tracks everything without a subscription, company has decent customer service despite them being hard to reach.. I’d say save your money and buy the oura.I love the concept of what they’re doing, I just feel like there’s a lot of work to be done to actually get it done right. I feel like if they do that they’ll have a lot of sales. I really wish my ring worked because I did like it and felt like the tracking was accurate.

Great product, but battery is lacking
I love the data the ring records. It gives lots of great insight. It’s comfortable. I’ve been wearing it pretty much around the clock for about 10 months. Unfortunately the battery has tanked. I can’t even get 24 hours of battery life anymore. It’s really disappointing because otherwise it is a great product.

J’ai adopté la bague Femometer il y a quelques mois et je ne la quitte plus.Sa discrétion est un atout, au quotidien, inestimé.L’application associée est très intuitive et me permet de suivre aisément mes cycles.Bien sûr, il faut un peu de temps pour s’habituer à la prise de température basale, mais les résultats sont là.Je recommande cet outil remarquable à toutes celles qui souhaitent mieux comprendre leur corps et planifier leur fertilité.

After a thorough read of the instructions, it’s a really easy piece of equipment to set up and use, to complement a fertility pathway. My advice is to contribute as much information as possible to understand your own body and build the best picture (analysis) to help with conception and possibly fertility treatment.
