Communicator 🔊

A collection of audio-based tools designed for fun, utility, and experimentation — starting with a high-frequency Mosquito Repeller that only kids can hear (or so they say 👀).

🚀 Features

• ✅ High-frequency audio tone generator (17kHz)
• ✅ Installable as a Progressive Web App (PWA)
• ✅ Offline support via Service Worker
• ✅ Works on mobile and desktop browsers

📦 Current App: Mosquito Repeller

The initial tool plays a sound around 17,000 Hz — often perceptible only to younger ears. Great for playful experiments with your kids (or as a summoning bell 😄).

📲 Install Instructions (PWA)

1. Open the site in your browser (Chrome or Safari recommended).
2. Tap the browser menu (⋮ or share icon).
3. Choose "Add to Home screen" or "Install App".
4. Done! The app will run offline too.
