Poor privacy safety
this app was rank one of the lowest to keep your information and data safe
Great but
In all honesty, this app is pretty good especially compared to other main source. Apps I prefer this one especially with the moon cycles. The only downside is that a lot of it’s locked up behind a paywall. I understand you gotta make money somehow, but the paywall’s are getting annoying and then all honesty. I just can’t afford to unlock all the extra stuff. I would love to be able to experience it, but just can’t afford to have another bill. Only reason it’s getting three stars and not 5

Love it but gitchy
Had to delete a while ago because it would keep crashing and losing all of my info, i put all of my history in again and again but gave up. Just redownloaded and am hoping for the best bc i really like this app
Slow and annoying
this app receives updates every two weeks and will not let you use the app without updating. i dont understand the required internet connection either, i shouldnt need internet connection to access what should be locally stored dates on a calendar. even after updating the app for the hundredth time and connecting to high speed wifi i still have to wait ages for the app to load, once it does load its slow and laggy, no other apps on my phone are as laggy as this. plus the constant advertising of a subscription with very superficial benefits can be a bit annoying. although it does technically work so not one star.

Need improvement
I have been using this app for years. It takes so long to load! The UX around adding a post dated period is confusing. Also more daily information about the cycle itself would be so helpful!
completely AI
asked about if i have pmdd. i do. it never used this info once. the worst part is that this app is completely AI and so i don’t trust its information at all. a lot of it gives misogyny when you think about it
Super exciting!
I really like this app so far, what’s more interesting and important is that they cite the sources they have used!
10/10

Would pick this app over all others!
I’ve never been so in tune with my cycle. Thanks to this cute app!
Partnership
I love how I can see what me and my friends cycles are in sync. I also love how you can share where you are on your period/cycle with your partner. I honestly love these features and it helps me feel more in touch with my friends.
Awesome! But..
Dont get me wrong! I love the app and its very accurate, just every-time i open the app it causes my phone to lag, and get very glitchy. Thats the only downside ive had so far.. :,(
My epic review
It’s somewhat accurate but glitchy as hell to the point where the app itself can barely function making it almost impossible to use
Lovely app but glitchy
I like the app a lot, but my phone freaks out whenever I open it! It takes ages to load, will make any audio playing on my phone stop and buffer, and often inside the app itself the buttons stop working and I have to restart. Plus, I love all the types of symptoms you can track (they’re very thoughtful and realistic), but I’m not aware of them being taken into account i.e. if I regularly track x before my period starts, and x happens earlier than expected, my period predictions don’t seem to be adjusted?

App constantly glitching??
it’s a great app! i love it so much! but recently whenever i try to open it to see when my next period is it glitches and just leaves me at the opening/loading “stardust” screen?? it gets really frustrating
Your Data is Not Safe
Stardust was caught sending out birthdates, birth control methods, pregnancy, and mood logs to an outside analytics company. (Study by the Mozilla Foundation)
used to be good
it was great until they put all the good features behind a paywall.
New update is bad
8/23/2026 I hate the new update. It SUCKS. Why did you move everything around?? I want to add symptoms to a PREVIOUS day. User interface is pretty but NOT INTUITIVE OR HELPFUL. It was at least more usable before.
Fun
It’s epic
I payed membership and it told me literally nothing but my period
I don’t like how i put in my symptoms, but it tells me nothing about why I have them and i don’t like it talking about my moon sign and weird stuff like that what does that have to do with my period?
Used to be good!!
Positives: love the variety of symptoms and log options. Especially with someone who has a lot of nerve pain it was great to track how severe it was during my cycle to show my log data to my doctors…
Negatives: I USED TO be able to see my history.. but now to my surprise sitting in the doctor’s office to show them my symptoms, it’s behind a paywall. To see your OWN PERIOD HISTORY the app is sneakily getting you to pay. Yes you can use the calendar mode, but what’s the difference to just using the scroll wheel to “gaze into my past??” Why force your customers to pay to scroll and see their own history day to day but allow them to see it in a calendar view? I know the term!! Cash grab!
Rather than what originally brought many other customers in… the fact you cared for us… it’s clear it’s becoming a cash grab from us.
Just another disappointment in women’s health honestly!! Enjoy at your own risk (the app looks great if you’re interested to pay for the application alongside your pads/tampons and pain medication!)

GLITCHY
Used to be great but it’s been super glitchy for a few weeks and no longer tells you what phase you’re in? Super annoying because that’s the reason I use it
