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.

Empezando a usar el app y anillo

Voy comenzando a usar el app me gustaría poder dar más especificaciones de mi estado actual por ejemplo tengo 2 meses de postparto y estoy dando lactancia exclusiva

Accuracy

The accuracy of the app is top tier! I have been allowing my man to cum in me everyday after it says my ovulation has ended & so far we have not gotten pregnant. No birth control needed!

Ring wouldn’t connect

After about a month, my ring stopped connecting and recording data

Not very perceptive

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. This past cycle I had a short LH surge and very short unsustained rise in temperature. The app recognized this as my day of ovulation. However, I knew it wasn’t my ovulation date because the rise was unsustained and actually dropped back down significantly. It was also about .5 degrees lower than normal. I ended up with a second (much stronger) LH surge about 2 weeks later and it did not recognize this as a shift. My temp actually went up .5- 1 degrees higher than the rest of my cycle, but my app is still saying my period is 9 days late. Instead, I know my period will be coming in about 5 days. I am able to figure this out, but the app isn’t. It’s useless at this point, so I may as well track on my own.
