HOW SURE ARE WE
Not in any grossing chart, so this comes from ratings growth (933 new ratings a month on average since launch): revenue grows with new ratings, more slowly for apps that collect ratings fast. Tested on 418 apps with verified revenue: typically off by about 2 times, and big earners tend to come out low. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

WHAT THEY COMPLAIN ABOUT · SHARE OF BAD REVIEWS
Price and subscription36%

46 of the 1 and 2 star reviews.

★★★★★ I was double charged by the app for over a year.
★★★★★ 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.
★★★★★ There is not an option to use points for a membership trial.
Worse after an update20%

26 of the 1 and 2 star reviews.

★★★★★ They also apparently updated the app and they're still having issues.
★★★★★ Whatever update was done I can't even use the app anymore.
★★★★★ With every update I think finally this will be resolved, but it just more of the same.
Crashes and freezes16%

21 of the 1 and 2 star reviews.

★★★★★ It force closes from the moment I open it and touch add anywhere.
★★★★★ App worked great the first day, now it freezes every time I try to upload an LH test.
★★★★★ For the last several months the app takes forever to open and then once it does, it doesn't load my data or even what cycle day I'm on for several minutes.
Bugs, things not working14%

18 of the 1 and 2 star reviews.

★★★★★ And also, with exporting period data, it's broken down weird.
★★★★★ Just got my ring… Doesn't sync to Bluetooth… Ridiculous you pay this much for a ring and it doesn't work
★★★★★ It stopped working and died after 3 weeks of use.
Lost data, sync, backup12%

15 of the 1 and 2 star reviews.

★★★★★ I tried closing the app, restarting my phone and finally I deleted the app.
★★★★★ Just got my ring… Doesn't sync to Bluetooth… Ridiculous you pay this much for a ring and it doesn't work

Wrong or poor results10%

13 of the 1 and 2 star reviews.

★★★★★ I used to really like this app and it was always spot on with predictions, but once my cycle stopped becoming regular, it became pretty much useless.
★★★★★ The app has been giving me a lot of issues. I'm able to track my periods easily and input all the data for that and my mood, flow, color, when I had sex, etc. But lately every time I open the app, there's a little…
★★★★★ This app was the most wasted time, energy and money. The test strips you used and scanned in gave you a % of ovulation but depending on the app, the same pee strip could be 140% or 200%… umm thats a pretty big…
No customer support10%

13 of the 1 and 2 star reviews.

★★★★★ 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.
★★★★★ I contacted support but they're taking forever to respond.
★★★★★ Customer support gives the same advice over and over which doesn't work.

Helped me track my cycle. Made FOR women. Great device.

★★★★★Oct 14, 2026
Sync Issues

The app is great about 90% of the time. There seems to be some bug issues on the occasion when syncing data in the mornings to my Ring Air 2 and it makes me nervous one day it’s going to just lose all of my data. Customer service is absolutely awful … I’ve had my ring for about a month, I’ve reached out to customer service 3 times and have never gotten a response …. I’ve had to use Chat or google to fix my issues and pray it works. Other than that I’m actually really enjoying the ring+app .

★★★★★Oct 7, 2026
The ring is fine, it’s the app I can’t stand

This app feels so useless and hard to read. The ring is just a recording device, but the app is the key to actually reading all data it’s recording and it needs some serious upgrades! For starters the AI interpretations flat out suck. It says the same thing practically every day and doesn’t even feel personalized to the data recorded for me. For example, based on my BBT it looks like i didn’t ovulate this month, but they AI insights give me information based on me having a very normal cycle. This ring is advertised to help you understand your own personal cycle, the AI tools should be able to take tour personal data and actually help you understand. And while we’re on the topic of BBT I’m just really not a fan of it only giving you access to 1 recording from the night. It shows you a graph and the fluctuations below but you can’t actually click on there and see what data was recorded throughout the night. Then you get to the part of the app that tells you if you’re stressing or not… cool feature IF done right but once again, a let down. Your app uses Ai as a tool to give its users insight to what the data collected means so why would we leave that out of the stress module? How many of your users can actually look at that all the graphs on that module that determine those results? It’d be nice to get a breakdown of what’s going on in that module that’s leading to a determination that says “you’re stressed.” Because you can bet that if i’m stressing, i don’t need an app to tell me that, i want the app to tell me what that stress is doing to my body. and the heart rate function pisses me off too because why in the world does that module only tell me my average unless i click the button to read it in real time? if i click the on the graph at a certain time i should be able to see what my heart rate was then, not “it was between 70-106 bpm.” again it feels useless. i want to love this ring it just feels like the app needs a makeover before i could say this was worth the money.
