PadConnect vs VirtualGamePad
VirtualGamePad also turns an Android phone into a PC gamepad, connecting over Wi-Fi or USB with a portable server for Windows or Linux and no extra drivers needed.
PadConnect vs BlukeBluke uses the standard Bluetooth HID profile, so nothing is installed on the PC, and adds keyboard and trackpad modes, but the phone's Android build must support HID.
