Just started to use this

Let's see how it goes

Just crashing

On a iPhone XR just a screen shows up that is immediately crashing. That‘s it...

Has saved me money!

I have been using this app for a while now and it’s really nice to see it’s helping me save money on my electricity bill! I don’t have a home kit thermostat to use with it but I just pay attention to the notifications and then make changes using the info it recommends. I would highly recommended checking with your electricity supplier if your home or business qualifies for pay by the hourly rates program before using this app for best results! Why I gave it 4 stars and not 5 is because of the following reasons. • It may seem a little intimidating when you first open the app and see all the settings and numbers. After a while it becomes easier to understand. • You do need a iPhone to use it. • Like I mentioned above, you should be on a hourly pay rate plan to fully use this to save money. Kinda out of luck for anywhere that doesn’t qualify for that service.
