Triggertrap has Triggertrap (iTunes Link) for the iPhone and iPod Touch in the iTunes App Store or Triggertrap for Android in Google Play for FREE (regularly 4.99) for a limited time. This deal expires December 31, 2012.

Trigger your built-in camera or your SLR camera with your iPhone/iPod/iPad, using more than 12 different triggering modes.

Of course, all the modes are fully configurable, to enable you to get trigger happy with your camera – in any way you like. We have even built in a Sunrise Mode (it uses the information from your GPS location to tell you exactly when the sun will set and rise where you are), and a Lag-O-Meter to measure your camera lag, for even more accurate HDR photography.

For many of the triggering modes, you can use the camera built into your phone, but if you want the full Triggertrap experience, hook it up to your SLR camera!

To connect your iOS device to a SLR camera, you can buy a Triggertrap Mobile Dongle separately. See the Triggertrap website for a list of supported cameras, and for more information. More than 280 camera models are supported.
