I love the aesthetic of this app, it truly is beautiful. It has a lot of options, so it almost feels like a mini journal of your cycle. But it's slightly more difficult to use than my previous cycle app and it randomly kicked me out and when I signed back in, a years worth of my period data was no longer there. Kind of frustrating. I really want to love it because of the entire concept, but some things could improve.

Hi April, thanks so much for the kind words and for bringing your experience to our attention. Don't worry, your data is not lost! Please try deleting and re-downloading the app ensuring that you log back in with the same method you used to create the account.

I really love the app and the whole aesthetic of it. But I am getting really frustrated with it. Two times now it has logged me out and when I've tried putting in the encryption key, it told me it was the wrong key, but it was the same key I had copied when setting up the account. The same thing happened with my security questions. It told me the answers were wrong. I really want to keep using the app, but I do not want to keep making new accounts every time it signs me out.

Hi Shannah! Thanks for reaching out. Our sincerest apologies for the difficulties you've been experiencing. Please ensure you have the most recent version of the app downloaded that was released today as this should fix the login sequence and give you access to your original account :) All the best, The Stardust Team

I love this app, but I wish we could select multiple options in the flow category. I also wish there were some other options in the symptoms category. I think it would be cool to be able to edit the options in the activities category as well. Other than those things, I love how easy it makes tracking my cycles, and how it gives me information about the moon at the same time!
