Seems unable to meet requirements described.
However, being a crafter, I needed an option to remote control my phone from my ipad, and while this appeared from the description to do so, it does not. It has more options in the settings than Camera Plus, like time lapse and timer settings. However it does not allow linking across two devices, or not that I could see from my brief time trying it.
The options available on it are just the same as the installed apple camera app, and the extras that seemed to be promised, did not appear to be there. I felt it was an okay option but did not meet my needs.
Would I avoid it? Possibly, it is easy to use,but it does not necessarily meet more needs than those already offered by the camera app pre installed.
