I've tried so many period apps but I always forget to open them. With Wetra I just WhatsApp my coach like I'm texting a friend. It actually fits into my life.

The AI coach explained why I get migraines before my period. No doctor ever told me that. I finally feel like I understand my own body.

Predicted my last two periods to the exact day. I travel a lot for work so knowing in advance is everything. Genuinely impressive.

I was skeptical about the WhatsApp thing but it's so natural now. I log in 10 seconds and get reminders without having to think about it.

The fertile window predictions helped us plan. We're now 9 weeks pregnant 🥹 Wetra was genuinely part of our journey.

Asked my coach about my mood swings and it walked me through the luteal phase in a way that finally made sense. This is what healthcare should feel like.
