CastDrop: TV File Sharing

📺 CastDrop — Screen Mirror, Cast & File Transfer to TV

Mirror your Android screen to TV, cast files wirelessly, and
collaborate in real time — all in one app. CastDrop is the fastest
screen mirroring and wireless file transfer app for Android, turning
your phone, tablet and Smart TV into a seamless cable-free ecosystem.

No USB sticks. No cloud accounts. No setup headaches.

🖥SCREEN MIRRORING TO TV

Cast your Android phone or tablet screen directly to your Smart TV
over Wi-Fi. Stream presentations, games, apps and video your TV
doesn't natively support — all wirelessly and in real time.

📌 Screen Mirroring Permission Disclosure
CastDrop uses Android's MediaProjection API (screen capture) solely
to stream your phone's display to your TV over your local Wi-Fi
network. You will be shown a clear permission prompt before any
screen capture begins. You can stop mirroring at any time from the
app. Screen content is never recorded, stored, or sent to any server.
CastDrop does not use the Android AccessibilityService API.
