femometer Ring Gen2 - Size Before You Buy, Smart Ring for Women(Size 8)

So far liking the product and had great costumer service when I got my ring, the battery level died within a day I sent over the details to the company and they resent me a new ring. The battery lasting long was one of my top likes. It’s been doing the trick for what I needed especially love the sleeping tracking feature. And AI insights based on measurements from the ring. I do wish I would have gotten a ring sizer and knew my ring size before or went up a size.

📈 This ring and its app are great. I've had it since January 2026. I got pregnant in May and it tracks my BBT accurately so early on I knew I was pregnant based on my raised temperatures. Also I only need to wear the ring at night which is nice because it clangs against dishes I wash and dumbbells while I'm working out. 🤰🍑🍋 It also gives a lot of insight into your cycle and especially your pregnancy. When the app switches to pregnancy mode, it shows a daily developmental fact of the baby, what size "fruit" you are and has so much advice and tools to help me get started on my pregnancy journey. This is my first pregnancy and I'm loving this ring/app to keep tabs on things. 👣💤 It also tracks steps and sleep. But because fitness tracking is not it's prime job, it's not like an Oura ring, and that's okay. It is still decent at some activity tracking though but I wear a Garmin fitness watch to see actual fitness data. The Femometer is really just best at cycle tracking/info. It's sleep tracking is on par with my Garmin though 👍

I have loved my ring! I have only been using it for a couple of weeks but it was a great investment. The best part is that there is no subscription fee needed to use the ring. It's a one time purchase and you can use it for life! It tracks everything you could ask for and is just like the Oura ring but more affordable and better. The only issue I ran into is when I ordered the ring I had to go through Amazon and not the website directly. It sucked becuse I was using a discount code from social media and Amazon would not honor the code so I had to pay a little more than I was going to if I could order through the website directly. The website only has certain size options for certain rings so make sure to check all the size option before ordering the ring. They send you a sizing kit once ordered so just make sure it will have all the sizes you think you might be or want to try. I ordered a size 11 and it fits perfect. I went up a size just to be safe and it was a good idea cause even if my finger swells it still fits and can take it off at any point doesn't get stuck. Otherwise it's been the best investment I have made for my health and is exactly what I was looking for when wanting a ring!

Battery was default or something they gave me was defaulted. Jen two has not worked for I’ve had it for about since August 24 and is not productively working at all. It’s not worth the price. The GEN one is surprisingly really good.

5 month update: Wanted to give a quick update now that I’ve owned this ring for 5 months- I am still loving it! It even helped me track my cycles and I can happily say my husband and I are currently expecting our first baby due in February! I haven’t had any glitches or connection issues. The battery is still holding strong too. It now has some slight wear and tear on the bottom side of the ring where the gold is beginning to wear off, but it goes unnoticed when looking at it from the back of my hand. Still think this is a fantastic purchase! Original review: Super happy with my purchase. I was a little skeptical with all the negative reviews but I’ve had my ring for a few weeks now and I can say I am happy with my purchase. I absolutely love the color and look of this ring. You don’t see very many white smart rings on the market. The tracking is accurate and I enjoy the extra content you get within the app. I think this is just as good if not better than more expensive rings on the market! A lot of other rings don’t include cycle tracking without purchase of other apps. Best all in one ring for females!

I wanted to love this ring so bad! It fit nicely and had great insights, however, I ended up returning it. The ring only detected blood oxygen levels the first day. Then it stopped working. The batter was losing 25-30% per day. This means it will NOT last even 5 days. This was a crucial part for me in deciding to return it. Plus it says water resistance 100m, BUT the user manual says to NOT wear it in the pool, shower, bath etc. and its only ok to keep on when washing your hand. So that makes it less useful for me. Other than all that the items that work were accurate.

I’ve been really impressed with this smart ring so far. It looks sleek and minimal, but it packs a lot of useful features, especially for sleep and health tracking. The ring is lightweight and comfortable to wear all day and night—I barely notice it’s on, which makes it perfect for sleep tracking. The ceramic finish also gives it a premium look and feels very durable. The data it provides is clear and helpful, especially for tracking sleep quality and overall activity. It’s nice to have something more discreet than a smartwatch while still getting meaningful insights. Battery life has been solid, and charging is simple and quick. The app is also easy to use and makes it easy to understand your stats without feeling overwhelming. Overall, this is a great option if you want a stylish, low-profile wearable that still delivers on performance. Definitely worth it.

I’ve had this ring for about 6 weeks or so and I love it so far. I wear mine day and night and only charge it every 4ish days. Before writing this review I have verbally recommended it to multiple women. I love the features it has for cycle tracking. You can get in depth analytics for sleep, cycle, ovulation, body temperature etc. I have cross referenced my steps and temperature with other tracking devices and it seems to accurately track. It’s very sleek and comfortable! I like to fidget with mine, so I notice when it’s not on. I ordered a size 9 and wear it on my index finger.

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.

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.

Ich nutze die Femometer App schon über 6 Monate und auch das Basalthermometer, mit beiden Produkten bin ich sehr zufrieden. Da ich ein Kleinkind habe und ich nicht jeden Tag morgens genau zur selben Zeit messen kann, habe ich mich sehr über dieses Produkt von Femometer gefreut, da die Temperatur bei mir dann sofort abweicht. Leider schwankt die Temperatur auch beim Ring sehr und man erhält nur eine grobe Übersicht über die Temperatur nachts. Beim Synchronisieren wird dann die aktuelle Temperatur übertragen, also bringt es eigentlich keinen Mehrwert. Der Ring ist sehr dick aber man gewöhnt sich dran. Die Ringgröße würde ich ggfs. eine Nummer größer bestellen, weil die Finger nachts etwas anschwellen. Die Installation, das Synchronisieren und die App sind spitze! Ich nutze den Ring im ersten Zyklus und leider wurde mein Eisprung falsch ermittelt (FA und CB Monitor 4 Tage später). Ich bin gespannt, wie es sich die nächsten Zyklen entwickelt.
