I downloaded the App earlier this morning and I've explored it.
For the first time I have access to data on my power useage, I suspect a household has to have a smart electricity meter installed as I do for this feature to work.
That's only one of the features of the AGL App and there's still a little bit of a learning curb for me with this App but doing just as much as I am now makes the App very much worthwhile.
I suspect other providers have similar Apps available from the IOS Apps store so it very well might be worth the follow-up.
