## Description

A lightweight mobile simulator for React Native developers. It loads your local development server (e.g., localhost:8081) inside a realistic, frame-only.

Unlike standard responsive viewers, Native Sim removes all browser UI distractions (address bars, scroll bars) and overlays a realistic Dynamic Island, Status Bar, and Home Indicator. This allows you to accurately test UI padding, Safe Area views, and "notch" interference without running a heavy emulator.

Features:
• Realistic android or iphone frames
• Pure "Frame-Only" view (No browser address bar simulation)
• Overlay hardware elements (Notch/Dynamic Island) to test safe areas
• Works with any localhost or Expo Web URL
• Zoom In and Out to fit the phone in the screen
