About this app

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.

Fabulous. I make timelapses for a hobby and replaced an old camera with a 4000d. Every DSLR I've had even 13yrs old ones have a remote port for intervalopters, not this one? However found this app, absolute cake to use and does job, what more can you ask for.
