CameraRemote allows you to shoot your DSLR camera with your mobile phone. It works with most Canon and Nikon camera models. You can now forget your old-fashioned remote at home without any worries. This app can replace it without any problem.
Don't forget to set your camera to IR mode and point your mobile phone at your camera’s IR receiver.
You can download the free app with ads, test it, and, if it works with your camera model, you may buy the full version without advertisement.
