Release your digital camera (eg. a DSLR) with your phone! Now with infrared blaster support. Release your camera with your phone using infrared! Required: Android 4.4. (KitKat) or higher, built-in IR-blaster. Tested with Canon, Nikon, Sony CameraTimer supports USB host mode of Android 3.X and higher. A special USB host adaptor cable is required. For earlier Android versions this small app can use the phone's built-in flash LED to release external electronic devices. Option to take shots with the internal camera with CameraTimer, including automatic geotagging. Releasing external cameras with optical cable requires phones, which provide a torch mode for their camera flash and a camera connection cable with a phototransistor to release the external camera. Check my website for details. New permission required: Internet, because of ad support. Bugs found?
