Your PCOD companion — track, learn, and thrive.

Inspiration

I built HerRhythm because I have PCOD myself.

When I was first diagnosed as a teenager, I felt completely lost. Nobody explained what it meant for my daily life. I searched for apps to help me manage it and everything I found was designed for adult women trying to get pregnant — not for a teenager just trying to understand her own body.

I couldn't find a single app that spoke to me as a teenager, explained things in simple language, or gave me personalised advice for my lifestyle. HerRhythm is what I wished existed.

PCOD affects up to 1 in 8 women globally yet remains one of the most under diagnosed and misunderstood conditions in teenage girls. I built this to change that — one girl at a time.

What it does

HerRhythm is an AI-powered lifestyle management web app specifically designed for teenage girls living with PCOD.

📝 Daily Log — Track sleep, food, exercise, stress, mood and symptoms every day with a beautiful, intuitive interface.

✨ AI Insights — AI analyses your real lifestyle logs and gives personalised PCOD-specific tips based on YOUR actual patterns — not generic health advice.

💬 Rhya AI Chatbot — Chat with Rhya, your personal PCOD companion. She knows your logged data and gives warm, personalised answers to anything about PCOD.

🩺 Doctor Appointment Prep — My most unique feature. Answer a few questions and get a personalised guide with questions to ask your doctor, symptoms to describe, and things to track. Built because girls with PCOD often leave appointments feeling unheard.

🌸 Cycle Tracker — A PCOD-aware period tracker that understands and normalises irregular cycles.

👭 Community — A safe space where girls with PCOD from different backgrounds share experiences, ask questions and support each other across topic channels.

📖 Learn — Bite-sized PCOD education written in teen-friendly language. No jargon, no scary stuff.

🔔 Notifications — Smart reminders to log, check insights and update cycle data.

How I built it

Technology Purpose
React Frontend web app
Supabase Database, authentication, real-time data
Groq AI — LLaMA 3 Rhya chatbot and Doctor Prep AI guide
CSS Animations Cinematic flower splash screen
GitHub Version control
Vercel Deployment and hosting

The app is fully responsive, works on desktop and mobile, and includes dark mode, page transition animations, and a cinematic flower bloom splash screen.

Every feature was designed with one user in mind — a teenage girl who has just been diagnosed with PCOD and needs a companion that speaks her language.

Challenges I ran into

Making AI feel personal, not generic The biggest challenge was making Rhya and the AI insights feel genuinely personalised. I spent a lot of time crafting prompts that connect advice directly to what the user actually logged — not just standard PCOD tips.

Designing for teenagers Every word had to feel warm, non-judgmental and empowering — not clinical. Getting the tone right for a teenage audience took many iterations.

PCOD-aware cycle tracking Most period trackers assume a regular 28-day cycle. PCOD doesn't work that way. Building a tracker that genuinely acknowledges irregular cycles required careful, thoughtful design.

Building solo Every line of code, every design decision, every feature was built by me — a teenager — in a very short timeframe. Managing scope while keeping quality high was a constant challenge.

Keeping real user data private Building with real health data meant thinking carefully about security, row-level security in Supabase, and making sure users always felt safe.

Accomplishments that I'm proud of

  • Built a complete full-stack app with real authentication, database and AI — solo, as a teenager
  • Created the Doctor Appointment Prep feature — something no existing PCOD app has
  • Built an AI chatbot that feels genuinely warm and personal, not clinical
  • Designed an app that teenage girls would actually want to use — beautiful, friendly and empowering
  • Created a real community feature where girls can support each other anonymously
  • Built a cinematic animated splash screen that feels like a professional product
  • Shipped a feature that comes from lived personal experience — something no big company can replicate

What I learned

  • How to build a full-stack web app with React and Supabase from scratch
  • How to integrate AI APIs to generate contextual, personalised health insights
  • How to write effective AI prompts for sensitive health use cases
  • How to design interfaces that feel warm and accessible for teenage users
  • That the best products are built by people who deeply understand the problem — because they live it
  • That building something personal makes you a far more motivated and creative builder

What's next for HerRhythm
