- low latency
- stream audio from host to target in projection mode, which can be used to stream music or youtube video sound from your phone to you Android TV (host and target device need to support opus format and target should be with Android Marshmallow or higher)
- works with some older devices (Android versions) that might not support Miracast
- can work with WearOS watch, if there's some compatible resolution supported

For this app to work, you need to enable developer options and establish ADB connection.

Ratings and reviews

Great app! it's a one of a kind app that supports mirroring and controlling another android phone using the wireless adb function. the free version has almost all capabilities and there's a paid subscription too for additional features. highly recommended for anyone whose display might be malfunctioning and have a secondary phone lying around to recover data from the damaged phone. saved my phone from months of data loss!

Genuinely the best screen mirroring app with excellent remote control features. However, the usability is tricky. Even with my experience in wireless debugging and ADB, it took me two days to figure out the setup—much less intuitive than LetsView or ApowerMirror. Needs better onboarding. It would be significantly better if there is option to turn off the display of the target mobile and the ability to simulate the power button command from the host device. or possibly adding terminal/shell.

i use this app to control my phone that has the lcd colors faded (amoled aging). its easy to use but i got a problem. when i connect again, its not connecting easily. i hope this is fixed soon but its a very good app only wireless debugging is required..
