Plug your phone in and its screen shows up in a window on your PC, with sound. Play phone games on a big screen, record or stream them with OBS, or just use your phone without picking it up.
Over a cable, the picture reaches your PC in about 20 milliseconds on our test phone, at up to 120 frames a second when the phone can do it. Your graphics card decodes it, so your PC stays free for everything else. Sound plays on the PC as well.
Linecast can capture the screen without installing anything on the phone or asking you to press "Start now" every time. Plug in, press Start, done. In this mode, teammates' voice chat from games and calls can play on your PC too.
Click and scroll on the phone from the video window, and type with your PC's keyboard. Device mode makes your mouse and keyboard look like real USB ones to the phone, so games that support a mouse get a proper pointer.
Copy text on your PC and paste it on your phone, or the other way round. Pictures can come along too if you switch that on. Copies that password managers mark as private stay where they were made unless you allow them.
The video window can be captured on its own in OBS (Window Capture, "Linecast — Video"). You can keep it on top of other windows, choose the shape of the picture, and change everything from your PC before or during a stream.
I'm Sreeraj, from Alappuzha, Kerala. I built Linecast because I wanted to play and stream my phone games on my PC without the lag and the hoops other tools put you through. It's a small, independent app and I answer support mail myself.
