App is not super user friendly. I think the suggestions and insights are better on other period tracking apps like lively. And it’s harder to log symptoms. But the ring works great. Great battery life. Very comfortable. Takes my temp and heart rate and O2 and sleep. All the things I wanted it to do ### 5/5 — Maravilhosa *2026-08-02* Perfeito ### 1/5 — Really poor customer service *2026-07-25, version 5.62.2* I was double charged by the app for over a year. I tried multiple times reaching out to the app developer. When that didn’t work, I reached out to Apple, who also was no help. ### 5/5 — Really like it! *2026-07-18, version 5.62.1* We got the ring and app for general health and NFP. We are really happy with the fast and the ease of use. ### 1/5 — Sketchy behavior *2026-07-15, version 5.62.1* I’ve been using this app since like sophomore year of high school and I’m 23. After years of collecting points, I finally had enough for the free premium subscriptions and of course they are “sold out” and have been for months RIGHT after I got enough lol. Mind you they have never been sold out ever. This app is probably one of those period apps that take your data accounting to google. Clue or Flo is a safer option because of the European privacy laws according to google. Don’t get this app ### 3/5 — Good app for fertility tracking but… *2026-07-15, version 5.62.1* I have loved this app up until I started tracking my pregnancy and adding my weight weekly. It’s telling me “you’re not gaining enough weight” then giving me info about “maternal under nutrition” and its making me worry about something that I don’t need to be worrying about because my doctor says everything is great. I hate logging my weight because I hate seeing that notification every single day it’s so annoying. ### 4/5 — Love this but.. *2026-06-27, version 5.62.0* I love this app but im pregnant with twins and haven't found a way to log that yet it just keeps saying baby sorta frustrating ### 2/5 — Ads on paid version *2026-06-27, version 5.62.0* I have been paying for this app for five years. It’a great. I love it. I’m not actually trying to conceive yet but I will be within the next year and have been tracking my cycle with this app fairly regularly for the past 5 years. However recently they started placing an ad for their new ring (think oura ring) on the app that they make you sit through for an unreasonably long time before you can open it and get to the app. I don’t want the ring. I didn’t want it when you offered it to us at 50% off and I certainly don’t want it now at 20% off. I’m really irritated that it’s being pushed on me so hard after I’ve spent $150 on this app over 5 years. This ad is getting in the way of me updating my data every morning. I’ll be happy to change my review to 5 stars as soon as I’m not forced to sit through an ad after paying $150 for the privilege of using the app. ### 5/5 — Femometer *2026-06-19, version 5.62.0* I’ve only been using this for a few days but I am learning more and more about my body thanks to the Femometer ring! ### 5/5 — Experienced tracker *2026-06-16, version 5.62.0* Keeps me on track and on my toes always prepared and excellent when I need to know when she is coming ## Frequently asked questions about Femometer Fertility Tracker ### What does Femometer do?
