Good idea but execution is for $2, not for $30
You can set up the schedule ONLY within one calendar day, from midnight to midnight? You CANNOT set up the app to run overnight, say from 5 PM PM to 9 AM? For $30? You must be kidding. You ask for 5 seconds of pre-motion recording at 1 photo per 2 seconds and get dozens of (useless) pre-motion photos instead of three? That's for $30? You get a useless pre-motion photo by email? The app randomly stops running by itself? That's security. Who wrote this, an elementary school student? Well, the green light next to the camera stays green - that is, no doubts, a deterrent. (But, well, $30 for turning the green light on?...)
iSentry Pro is a start in the right direction
While we had used the free version of iSentry for about 6 months with good results, the extra features of iSentry Pro appeared to be reason enough to pay for the upgrade. After using Pro for a few months, we are getting mixed results - with app stability being the main issue. It is usable, but not particularly reliable. A bug fix could easily make this a four or five star application.
iSentry Pro is a rip off
The free version tricks you into purchasing the Pro version with the promise of more functionality and USB camera capability (free version works only with iSight). Not only does it not work with a USB camera, the app is so buggy that it slows and freezes my Mac at random, typically requiring a restart. I made the mistake of assuming that since it was available in the App Store, it must be okay. What a rip off!
