It’s great!

I use this every day - sad as it may seem! With energy prices on the increase I wanted a way of monitoring my daily usage of gas and electric. This app does just that. It’s helped me offset electricity usage onto the Go nighttime period. It also helps me keep on top of Octopus payments to make sure they’re not setting my direct debit too high.

My only suggestion for improvement is to have a graph that can track monthly usage (and have a line for the previous month for comparison).

Developer Response ,

Hey thanks for the review. At the moment I only load the last 30 days but it retains any data you may have before that. Graphs is definitely I want to look at for sure !

Energy Watch App

It is great to be able to monitor energy usage daily and this app is ideal for monitoring your daily electric and gas usage. I had some teething problems with the early set up but the App designer offered excellent advice which fixed the problem. With energy prices going through the roof, this app enables you to take action quickly when you see a problem.

Thanks for the kind words and glad I could help 🙂

Better than Octopus’s own app

It’s difficult to get a clear idea of costs on flexible tariffs, and Octopus don’t do a great job to help. This is where this app comes in - really helps you to understand the effect of shifting power consumption to different times of the day. The developer is also friendly a d responsive to support requests. Recommended!
