Updated rating: Needed help but couldn't get past the chat bot to talk to a live person on both the app and their website. It was during the week and normal business hours. ************************************** Old rating: Love it. It's in English, and you can keep track of your usage and payments.

In the past few months the app has become very unreliable, with continuous errors when reporting meter readings.

Online and digital yes, but forced to install an app is very annoying. Beside the Facebook and Google trackers in the app... Maybe simply provide an homepage... Thanks!
