Inspiration
Last year, I was diagnosed with PCOS (Polycystic Ovarian Syndrome), a chronic hormonal and metabolic condition that affects 1 in 8 women. There’s no cure (and doctors weren’t helpful), so I spent many months dealing with all my symptoms while also researching to figure out what the perfect mix of diet advice, supplements, and lifestyle changes I should apply to take care of my health.
After all my research and experimentation, I saw real improvements with my symptoms. I built PCOS Polly so millions of women can immediately access the tools and resources I wish I’d had when I first found out I had it.
What it does
- Personalized onboarding to capture symptoms, goals, and preferences—followed by a RevenueCat paywall for subscription access.
- AI-powered daily routine: recommended nutrition targets plus a custom routine of habits and supplements (fully customizable). Powered by Gemini.
- AI Meal scanner & guidance: check if a meal is PCOS-friendly and get tips to improve meals to reduce symptoms. Powered by Gemini.
- Daily habit tracker: for meds/supplements/habits with gentle OneSignal reminders if users forget to track
- Streaks + gamification: a friendly flower character, Polly, grows from sapling to full bloom as users log more days in the app
- Timeline & period log: to review past days and track menstrual cycle irregularities
- AI chat: for supportive guidance and answers to real-time PCOS questions and concerns
How I built it
- App: Expo React Native (TypeScript).
- Auth & data: Firebase Auth + Firestore
- Billing: RevenueCat for trials, paywall, and entitlements
- Notifications: OneSignal with personalized daily reminders, onboarding drip campaigns
- AI: Google Gemini for chat, custom routine, and food scanner
- Design & Marketing: all done by me in Figma & CapCut
Challenges
- Getting approved by the App Store took longer than I thought, it was almost a week of back-and-forth rejections and requests
- Launched the app pretty late into the submission window so only had time to make a few TikToks on my own! I’ve never made social media content before so it was a bit of learning curve to get comfortable being vulnerable online.
Accomplishments that we’re proud of
- Shipped on the App Store two weeks ago
- Without paid ads or influencers: 40K views on TikTok, 300+ installs, 40+ paying customers, and $3.5K ARR already (as of Sept 30th).
- UPDATE: As of Oct 7, I'm now past $11.1K ARR and it's been really exciting to see the explosive growth over the past few days!! Chart below:

- Very solid paywall conversion rate & positive feedback from early users
What’s next for PCOS Polly
