Slick, Fast, Simple

Earlier this year, I decided that I should make an effort to shift my energy usage to off-peak hours. After having a smart meter installed to enable he superb Octopus tariffs where prices change depending on the time of day.

Then I wanted to track how I was doing on a daily basis to make sure I was managing down my electricity cost.

This app is, in my opinion, the single best way to do that. I can be in and out in seconds, reassured that the cost is going down, or making a plan to change something. I can effortlessly view the cost and usage in 30 minute intervals.

A beautiful, well thought through, excellent app which is regularly maintained.

Does exactly what it needs to

Easy to use way to keep track of your energy use and much more reliable than the in-house display.

Like the appliance reminder notification.

The perfect app

… for checking how much you are spending on the smart Octopus tariffs. Having recently switch from Agile to Go Faster I was thrilled to notice this app from the same developer as the trustee Agile Watcher.
