I really love this app and appreciate the fact that it's bugging so much less! Been using it since its launch and it's been very accurate to this day. I wish they added a agenda... Seems weird but it would be great to have one where I could plan my activities in function of my cycle. I have not seen any app do something like that so far and it could take it from good to awesome. Something with reminders... Not even necessarily a cloud but yeah and also moon cycles... Because that matters too!

So incredibly glitchy and laggy. there have been so many times I've opened this app to quickly check something, or give some information to a doctor, and this app just gives me a blank screen when trying to open it. It's annoying and embarrassing. not to mention the whole issue going around about stardust selling your personal data. It's a shame there aren't any good period apps out there, all of them either suck or sell your information.

I switched to another app during the data selling controversy, but also because even on a new phone the app was so laggy. I came back because I couldn't find another app that works well, that’s not extra ugly, doesn't sell your data or doesn't force you into a subscription. Stardust definitely has improved although the UI could still get refined. It is still not smoothly running but it’s not as bad as it used to be. There's a lot of useless aesthetic things I do not need but it's fine.
