I paid .99 once and installed on all 3 of my devices...iPhone4, iTouch4, & iPad2. Works as described.
Nice functions such as being able to control the camera device features from the remote device. Like flash & autofocus. And I was able to take pictures remotely from several rooms away, over 25ft!!
Only let downs are the remote preview quality (choppy image) & the fact that it doesnt rotate the camera device properly (buttons rotate but image stays upside down).
I hate when people write bad reviews about apps when its their fault they dont read the DESCRIPTION!! Its not meant to work with real cameras!!
