I wanted to quickly setup a time lapse video of a function that I went to, and had not prepared ahead of time. Bought this app with little research. It was quick to setup on my mac air, let me immediately capture photos from the built in cam, and build them into a time laps. So in that regard it servered its purpose well. On the other hand, the app is pretty basic. I was not able to test out various speeds of assembling the photos into movie in order to see what worked best, etc. Definitely worth the price for a simple application.
