User reviews

Better communication tool

Instead of awkward talks, I just update my status. My partner checks it and understands what kind of day I’m having. The little support interaction feels simple but keeps communication open.

Fun with my close friends

I connected with two close friends and we compare cycle phases. It’s surprisingly fun to see when we’re all in the same mood zone. We tap support and send memes when someone logs cramps or stress.

Easy to share updates

The interface makes it simple to share mood changes with my boyfriend. When I mark that I’m overwhelmed, he reacts with the support feature and offers help. It turns mood swings into teamwork instead of conflict.

Makes PMS less lonely

I used to just deal with PMS quietly. Now my partner can see when I’m struggling and sends support right away. Sometimes he asks what snack I’m craving because he saw my status. It feels attentive.

Perfect for busy couples

We both work crazy hours, so quick updates help. I log symptoms and moods, and he responds with a tap or short message. It keeps us connected even when we barely see each other during the week.
