This tracker is the one I personally use in England, so it incorporates conversion factors for cubic meters of natural gas to kilowatt-hours and the prices per kilowatt-hour charged by my supplier. We have a wood-burning stove, so I make a note when I use it - but I removed the 'average fires per day' trace from the graph below for clarity.
Tracker configuration and customization are the design goals of rTracker, so creating the specific utilities tracker for your local needs is simple. With rTracker installed, click Download Utilities.rtrk on your iOS device (iPhone) to install this tracker, then click 'edit' and make it work for you.
Combining rTracker data with a lot of thinking and hard work, our household electricity usage is now 1/7 (one seventh) what it was over the months after we first moved in. Last winter our gas usage was 1/5 (one fifth) what it was during that first winter. Result!
