I am looking for something that will allow me to set up my camera on my phone to take a picture every 10-15 seconds for a finite period of time, say 5 minutes or so.
Folks, read the OP a bit slower. Camera + lets you use a timer to take a photo; however, it does not allow you to set it up to take multiple photos every 10 or 15 seconds for 5 minutes without some sort of interaction from the user.
Its primary use is to make a time lapse video, but you can set it to save each photo it take to the camera roll. So you'll get the photos in addition to the video.
