the app is good, i do recommend but the notifications they send are gross and vulgar and almost piss me off more when i’m on my period.

I really like this tracker. It gives a clear understanding of what’s going on in my cycle by day. I just finished learning this in my biology class so to see it in practice is so helpful. If i had a real income I would pay for the plan because after the trial it is very much worth it. But the free is just as good

I love Stardust so much. The little quizzes that tell you more about yourself are super helpful, and it’s a great app that has all the features: ovulation pregnancy stuff and just regular period predicting. It’s also super helpful when you wanna know what your symptoms for that day will be like, it can pretty accurately predict what it will be. Highly recommend, best app ever!

It's just great. I love the notifications. They are actually pleasant to receive unlike most notifications. They have a great sense of humor. I love that you can tell the developers put a lot of effort and love into it. Thank you women!

I like it a lot. It gives detailed explanations for the cycle, educates well and even sends notifications every day updating on your partners cycle. Recently it started bugging in the notifications, failing to update the cycle properly.

I LOVE this app! It’s so fun and totally made for the starlings and the seekers! This is the only one I’ll use!
Suggestions to make it EVEN better - I’d love it if instead of setting my length of cycle, Ai could track my prior cycles and make predictions. Same with symptoms. If it could analyze my symptoms and days they fall on and then predict them, that would be even more helpful!

it’s super accurate and reliable. the app itself has a nice lay out, super easy to use. i would highly recommend it!!
V92813 • Jun 7, 2026
Based on the reviews I thought that this would be great however I can only use an apple account for it and mine does not work like that so I cannot use it☹️
Frybread gobbler • Jun 6, 2026
My sister showed me this app and it’s actually been mostly accurate on telling when my next moon cycle will be. I say mostly cus mine are always irregular but they’ve been closer to telling when I’d be than other apps I’ve used. So far I’ve had it over I think a couple years? Idk but I’ve had no problems with the app

Your ad on YouTube was extremely sexist and honestly the most immature thing I’ve ever seen.
Webtoonie1465 • Jun 6, 2026
Whenever I am on my period I always like to appreciate little things that happen and with stardust, there is so many things like that like your ‘tarot’ card or what phase of the moon you are in and it makes me so happy. And adding in statistics like “You were born under a new moon like 3% of stardust users” stuff like that makes me feel seen and almost normal in a way.
Maleah Williams • Jun 6, 2026
I really wanna like this app, it’s pretty cute and I like some of the features but good God there’s been multiple times where I’m sitting in the doctor and they’re asking me when my last cycle was and I’m sitting there for however long trying to open this app and it just doesn’t launch. Like that’s my whole purpose for having the app. It literally takes forever to load. And it’s super hard to change that first test. So I can get an accurate cycle calendar it literally wouldn’t let me change my cycle so it kept saying my period was coming like 10 days before it actually was even if I plugged in my cycle dates. it’s just buggy and flat doesn’t work.
weelters • Jun 6, 2026
the app itself is good, i love the way it incorporates the moon phases with my cycle and gives me lots of information and daily updates. however sometimes it glitches when tracking my period and the app takes ages to open from the loading screen, sometimes not even allowing me to open the app at all.
The app yall banned • Jun 6, 2026
Takes a little long to load and u have to pay for giving 😐
Kathrynjustletmepostmyreview • Jun 6, 2026
I really like the style of the moon and stars and that i think this is a women owned app and i like learning the stage im in but its un motivating have the app tell me to do nothing all day and see how little i can do and get away with like i have a daughter i cant be lazy it just makes me kind if mad reading that and like all i want is to learn about my body im not your best friend and it is like im in tiktok and thats not ideal
mckayrin • Jun 5, 2026
I wanted to love this app so much, especially because it is woman ran. The app itself is great, I just have the free version but the notifications are cute and I appreciate that I can share it with my partner. The deal breaker: it does not accurately track. Like at all. It goes based off of your last period, or what you may have put in the system such as periods are every 4 weeks for 5 days. It keeps those settings applied, even if you’re tracking a changing period. My periods come later each month and for a year now this app has tracked it as starting when my last one did. I even adjusted the settings to where it states I have them every 36 days or whatever and it still tracks it at around 27-28. Please, if yall can, it would be a great fix. I would hate to have to use Flo!

Stardust is a great app a little confusing at first but it got my irregular period right and I was shocked I totally recommend
EverQuest enjoyer • Jun 4, 2026
So I am still a minor and have irregular periods, and this app really does help with preparing ahead of time but lately I have been seeing that “Your next period in 50 days” and then being extremely confused and I don’t know how that happened. I really do like the app and the forecast messages really make me laugh but the time in between my periods is just really confusing. I know that that might be accurate for people older than me but I don’t think a teenager should have a 50 day cool down. But that is just me, besides that, I really do love the app.
BMK9999 • Jun 3, 2026
It’s been so off on some of my phases even though I’ve been using it for a few years. I tried to correct it once and it wouldn’t let me. I used to love the notifications and the verbiage for each day but they honestly got to be a little much like other users said. I get the humor but I wasn’t feeling ‘ugly’ then checked the app now I’m questioning if I should feel ugly? Not great for the self esteem. Also same with the symptoms it’ll say you have. Not everyone gets those so it seems to be a bit over kill. I know they are trying to be funny but it doesn’t always land.
SaaS Metrics
Imagine being 15, getting your first paycheck, and then finding out a period tracking app took $37 from your account after you canceled the free trial.
I deleted the app because it wasn’t worth keeping. Apparently it was worth keeping my money, though.
Would not recommend.
