+
+**CycleSyncAI** is an iOS app designed to provide personalized **diet and workout recommendations** tailored to a woman's **menstrual cycle phase**.
+
+By integrating menstrual data from Apple **HealthKit** and optional user profile inputs (age, weight, height, medical conditions, dietary restrictions, goals, and preferences), the app generates dynamic, phase-aware suggestions to support holistic wellness.
+
+Unlike static wellness tools, **CycleSyncAI** leverages **Perplexity's Sonar Pro API** to deliver **expert-informed**, LLM-generated guidance — including a daily grocery list and motivational feedback — customized to the user's cycle and lifestyle.
+
+## Problem & Solution
+
+> **Why it matters:**  
+Most apps overlook the hormonal changes that affect women's fitness and nutrition needs across their cycle, leaving users with generic advice.
+
+**CycleSyncAI** bridges this gap by combining Apple HealthKit data with Sonar Pro's LLM to generate **adaptive, cycle-aware recommendations** for better health outcomes.
+
+## Features
+
+* **Personalized diet & workout suggestions** per cycle phase
+* Syncs with Apple HealthKit for real-time cycle tracking
+* User profile inputs for advanced personalization (age, goals, restrictions, etc.)
+* **Auto-generated daily grocery list**
+* Smooth, modern UI with gradients and subtle animations
+* **Motivational AI feedback** tailored to user preferences
+* Local data storage and private processing
+
+## Motivation
+
+> "I wanted a tailored regime for myself and couldn't find it all in one place."
+
+**CycleSyncAI** was born from the need for a science-backed, easy-to-use app that adapts wellness guidance to women's natural hormonal rhythms, something missing in most mainstream fitness and nutrition platforms.

+1. Clone the repo  
+2. Open in **Xcode**  
+3. Ensure Apple HealthKit is enabled on your device  
+4. Insert your **Sonar Pro API key**  
+5. Run the app on a physical device (recommended)
+
+## Sonar API Usage
+
+The app sends structured prompts to the **Sonar Pro API** including:
+
+* Cycle phase (from HealthKit)
+* User profile info (age, weight, goals, etc.)
+* Meal preferences & restrictions
+
+In return, it receives:
+
+* **Personalized diet plan**
+* **Custom workout plan**
+* **Daily grocery list**
+* **Motivational feedback**
+
+These are parsed and rendered as styled HTML inside the app using WebViews.

+
+## Impact
+
+**CycleSyncAI** empowers women to make informed, body-aware decisions in daily life. The app supports better:
+
+* Energy management  
+* Fitness results  
+* Mental well-being  
+* Motivation and confidence
+
+It also reduces decision fatigue with automatically prepared grocery lists and uplifting guidance.
