I am using the Pentair iPhone app. I am very disappointed with it. I was hope to use my iPad and old iPhone to control the pool, instead of buying one of their wireless controllers. I am still thinking about buy a wireless controller but the $800 cost is a bit much after all the money I already spent on upgrade from the EasyTouch to the intelliTouch. First there is no iPad app, it is just the iphone app on the iPad. The only thing it is good for is turning the spa, blower and pool lights on (I had to make a macro for the pool lights so not sure if it will work on the i5+3 board). You can not make any adjustment to the equipment (i.e. pump speed, chlorinator or color of the intelliBrite). You need to get on the computer and use the ScreenLogic software, which can use a lot of updating.
At time the iPhone app will not connect over the internet. It can go for a week and never connect then one day it will start working, no clue why, I have the app on a couple of phones, Tried rebooting the phone, router and no luck and then on day it will just start to work.
I think the route is an off the shelf route that was pre-configured for the system. The only thing it looks like they added to the router setting is some port forwarding. I asked tech support if I reset the route will it lose the settings, the answer was YES. So I wrote down all of there setting in case I need to replace the router.
