Period, follicular, ovulation, luteal — Girl Harmony explains what's happening in your body today, not just where you are on a chart. No jargon. No guessing.
Bestie is an AI cycle coach trained on your real logs. Ask anything — "why am I bloated today?", "is this cramp normal?", "should I push my workout?" — and get an answer that actually fits your body.
Generate a polished report for your OB/GYN, therapist, fertility specialist, perimenopause clinician, or pharmacy in under a minute. Bring data, not vibes.
Talk instead of type. We transcribe in real time and surface the emotional themes across your cycle so you can finally see the patterns.
The first cycle app built with Halacha in mind. Selectable customs, hefsek taharah & shivah neki'im tracking, mikvah reminders. Private and respectful.
End-to-end encrypted. We never sell your data — to anyone. And you can delete everything, anytime.
Your cycle data is encrypted, never sold, and you can delete it whenever you want. That's the whole policy.
