Meditate with Fractals

"Meditate with Fractals" is an application designed for relaxation and meditation. It combines procedurally generated visuals (fractals), generative ambient audio, and AI-powered customization to create a unique, infinite experience for the user. The first meditation app powered by AI.

1. Visual Engine (WebGL)
The app uses a complex GLSL fragment shader to render visuals in real-time (60fps). It does not play video files; it calculates pixels mathematically. Generates smooth color gradients that can be updated in real-time via AI.

6 Unique Modes:
1. Tunnel: An infinite log-polar zoom into a fractal structure.
2. River: A fluid, domain-warped pattern that flows like liquid.
3. Mandala: A kaleidoscope effect with 8-fold symmetry.
4. Vortex: A twisting, high-contrast neon spiral.
5. Crystal: A geometric structure using "box folding" algorithms.
6. Lotus: An infinite tiling of soft, pebble-like shapes radiating outward.

2. Audio Engine (Generative)
Instead of streaming large MP3 files, the app generates sound on the fly using the Web Audio API.

Om/Drone Mode: Creates a binaural beat effect using two oscillators slightly detuned (136.1Hz and 140.1Hz) to generate a 4Hz Theta wave for deep relaxation.

Rain Mode: Generates Pink/Brown noise programmatically using a buffer and applies a low-pass filter to simulate the sound of heavy rain.

Includes a slider to mix the generative audio volume.

3. AI Customization (Google Gemini)
The app integrates with Google's Gemini API to personalize the experience.

Mood Painting: Users can type a mood (e.g., "Cyberpunk Forest"), and Gemini generates a specific JSON color palette (4 vectors) which is instantly applied to the running shader.

AI Voice Guide: The app generates unique, short meditation instructions based on the current mood using Gemini text generation.

4. Premium & Monetization
The app operates on a Freemium model, guarded by a subscription system.

Free Features: Access to all 6 visual modes and the "Breathe" visual guide.

Premium Features: Paint, Audio Voice Guide, Generative Music, and Speed. Controls are locked behind a paywall.

RevenueCat Integration: The app uses the `@revenuecat/purchases-capacitor` plugin to handle Google Play subscriptions.

5. UI & UX
Breathing Anchor: A central pulsating circle helps users synchronize their breathing.
Minimalist Interface: Controls are semi-transparent and auto-hide to minimize distractions.

Tech Stack: Built with standard HTML/JS/CSS (Tailwind for styling), designed to be wrapped by Capacitor for native Android/iOS deployment.
