Install both apps, connect them on the same Wi-Fi, and your phone becomes a wireless mic for your PC.
Download OwnMic for Windows from the Download page. It comes as a .zip — open it and run OwnMic.exe. If Windows shows "Windows protected your PC", click More info → Run anyway (OwnMic is new, so Windows doesn't know it yet).
So other apps (Zoom, Discord, OBS, games) can use your phone as a mic, install a free virtual audio cable such as VB-Cable. OwnMic feeds your voice into it, and it appears as a normal microphone in Windows.
Download the OwnMic APK on your phone and open it. Allow the microphone and local network permissions when asked.
Connect the phone and PC to the same Wi-Fi. No router? Turn on your phone's mobile hotspot and connect the PC to it — OwnMic will still find your PC. No Wi-Fi at all? Use a USB cable.
Open the app on your phone — it lists PCs found on the network. Tap yours, then enter the PIN shown on the PC. This pairs the two so they connect instantly next time.
In Windows sound settings (or inside Zoom/Discord/OBS), pick the virtual cable as the input device. Talk into your phone — you're live. Use Mute or the floating widget to control it any time.
Tip: Keep both apps updated for the best latency and stability. You can "forget" a paired device from either side whenever you like.
OwnMic also works over a USB cable using your phone's USB tethering. The cable makes a small private network between the phone and the PC, so you don't need Wi-Fi. It's usually the steadiest connection, with the lowest delay, and your phone charges while you talk.
Saving mobile data: While USB tethering is on, Windows may use your phone's mobile data for its internet. OwnMic itself doesn't need the internet, so you can turn off mobile data on the phone if you'd rather not use it.
