Its a good app working very well on my Iphone5S and also my Ipad2 Only problem I am having is eats my phone battery so fast. My battery was %100 and used this app to adjust some of the security cameras outside for 15-25 min so and used %40 of my battery and My battery is %60 now. Needs improvement on this side. I am using a lot of apps for different jobs and this one is the only one uses this much battery.
