Crashes & Freezes
It can't get much more useless than this app. The app crashes on startup or freezes. The farthest I got was adding my zip code. Then a grey screen. Deleted. iPhone 5, iOS 7.0.4. I have a P3 International P4400 Kill A Watt Electricity Usage Monitor that goes inline between the appliance and the receptacle. This works very well on a fridge which runs variably depending on the number of visits to open the door as well as the ambient room temperature. You can run a 7 day test to get a pretty good idea of energy consumption.

Doesn't work
Downloaded, entered zip, then nothing but a blank gray screen. Tried uninstalling/reinstalling, location services on/off, restarting device, same result each time. Rather disappointing as we're having a solar system installed in the next few months.

Pretty rad!
A pretty easy way to keep track of how much energy you're wasting. Works great in ios 6 with a slick iPhone 5 interface!

Simple and thought-provoking
This ap is really easy to use and makes me think every time I turn on any appliance. Right now, I'm working on an outside light that has a broken light sensor, that keeps it on all the time.

Really interesting
This is a pretty simple, but useful, app. I always try to convince my roommates to turn off the lights. Now I can show them why.

Pretty useful
Great app. Beautifully designed. Keeps me very aware of how much energy I waste for no reason.

Simple but effective.
A basic idea implemented well. Hopefully they add more bells and whistles as time goes on. Really enlightening to see how much electricity things consume (or don't consume).
