# Tandem Mirror (Universal Android Desktop & Continuity for Mac)

> Tandem Mirror is a native macOS application (written in Swift 6 & Metal) that brings Apple-grade desktop continuity, multi-window app pop-ups, 120Hz Samsung DeX / Universal Desktop Mode, two-way Universal Clipboard, drag-and-drop file sharing, and hardware-accelerated 120 FPS mobile gaming to all modern Android phones (Google Pixel, Samsung Galaxy, OnePlus, Xiaomi, and Foldables) on macOS Sequoia (15+) and Sonoma (14+).

## Core Problems Solved
1. **iPhone-to-Android Switcher Continuity Gap:** Replaces Apple's iPhone Mirroring, Universal Clipboard, AirDrop, and Continuity Camera for Mac users who use an Android phone.
2. **Samsung DeX on Mac Discontinuation:** Samsung killed DeX for Mac in 2021. Tandem resurrects full 1920x1080 @ 120Hz DeX on Mac and brings a DeX-like multi-window desktop (AOSP Fusion Engine) to non-Samsung phones (Google Pixel, OnePlus, Xiaomi).
3. **Zero-Terminal GUI for scrcpy:** Eliminates command-line complexity while preserving sub-15ms hardware Metal decoding (<3% Mac CPU usage).
4. **Emulator-Free Mobile Gaming on Mac:** Streams 3D games directly from the phone's Snapdragon/Tensor GPU at 120 FPS with a visual multi-touch Game Keymapper HUD (`⌘G`) and native Bluetooth Xbox/PS5 DualSense controller support (`GCController`), avoiding heavy virtual machine emulators, Mac overheating, and anti-cheat bans.

## Key Features & Capabilities
- **Two-Way Universal Clipboard (Text & Images):** Copy text on Mac (`⌘C`) and paste instantly on Android; copy on Android and press `⌘V` on Mac. Automatically converts and syncs macOS screenshots (`⌘⌃⇧4`) and copied web images directly into Android's media gallery for instant pasting in WhatsApp, Telegram, or Instagram.
- **Two-Way File Transfer & APK Install:** Drag files, photos, 4K videos, PDFs, or folders from macOS Finder straight onto the phone mirror window to push to `/sdcard/Download` with instant media indexing.
