EHW+ is the most complete solution for finding out about one’s own consumption of electricity, heating, and water. The free EHW+ app allows users to record their consumption and the corresponding costs.

In addition to electricity, heating, and water consumption, users can also record their gas meter readings.

Once you have completed the recording, you can use the resulting database to make various calculations, including how much money you have saved or how much it would cost to make your house warm again.
