Stream PC audio or microphone to mobile easily, in the blink of an eye. You're on your PC that doesn't have Bluetooth and you want to use your portable speaker? Use this app. Or even if your computer has Bluetooth, it is limited in range of usability - want to extend your area of music as much as you like? This app is a perfect fit.

Made with Electron, React, Flutter, naudiodon (PortAudio wrapper for Node.js, it doesn't require having PortAudio on the machine) and... my own easy-volume library.

🔄 Intelligent reconnection system - to prevent random breaks in audio delivery or connection problems

NOTE: On the default Android settings, the mobile app may be automatically closed by the app manager due to it being in the background. To fix that, please change the battery settings for the app.

Run

See the Releases tab. Download the latest desktop app - either the installer or the unpacked version - and the latest mobile app.

The app will work out-of-the-box.
