Spieglein

Spieglein casts the screen and audio of your Android device to your Windows PC over Wi-Fi — with a single tap.

You'll need the free receiver app "Spieglein Android" on your Windows PC (Microsoft Store). No cable, no USB, no developer mode: open the app, tap "Start casting", confirm the system dialog once — done.

✨ FEATURES
• Cast both the screen AND internal audio (music, videos, app sound)
• Entirely over Wi-Fi — no cable needed
• Native resolution, rotates automatically (portrait and landscape)
• Selectable quality: Native, High or Medium (saves battery/bandwidth)
• Your PC discovers the device automatically on the network
• Multilingual — German and English

🔒 PRIVACY
• 100% local: video and audio stay on your Wi-Fi; nothing is sent to servers
• No accounts, no login, no tracking, no ads

🖥️ REQUIREMENTS
• Android 10 or newer
• A Windows 10/11 PC running "Spieglein Android", on the same Wi-Fi

⚠️ NOTES
• Some copy-protected apps (e.g. streaming services) don't provide audio for capture — that's an Android limitation, not a flaw in Spieglein.
• Casting only (phone → PC): controlling the phone from the PC is not part of this app.
