Record pixel-perfect Android gameplay without a capture card.
DoppelCast turns the USB cable you already own into a capture card. Pick your resolution, bitrate, and frame rate, plug in, and record straight to your PC. No dongle, no HDMI splitter, no subscription.
Three steps between you and a recorded clip.
No firmware, no capture drivers, no second PC. If your phone can talk to ADB, it can talk to DoppelCast.
Plug in your phone
Connect your Android device to your PC over USB and enable USB debugging when prompted. DoppelCast detects it automatically.
Set your quality
Choose resolution, frame rate, and bitrate independently — from a lightweight 1080p30 clip to a full-bitrate native-res capture.
Hit record
Capture lands on your PC as a ready-to-edit file. Stop whenever you want — no proprietary container, no re-encode required.
The hardware box was never the interesting part.
A capture card just moves pixels from one cable to another. DoppelCast reads the same signal straight off the device.

Every dial a capture card locks down, unlocked.

From a data-light 480p up to your phone's full native display resolution.
Any frame rate

Any bitrate
Dial from a lightweight 5 Mbps up to broadcast-grade 100+ Mbps VBR or CBR.
H.264 & H.265
Pick the codec that matches your editor, your upload target, or your storage budget.
