I am so surprised by the negative reviews. This is by far the most useful app I have on my phone. I am a stay at home mom and this app helps us save money. I love that the kWh usage is broken down by the hour. I spent a few days keeping track of what I did all day and then after comparing with graphs on app, I was able to figure out what uses the most electricity. This app really helps you conserve. Plus, its almost a challenge to see how low I can get the daily kWh down. Great job! Side Note- I use this app on a iPhone 5c and only have one account.
