YelloStrom Energy App

We at TamTam love energy, mobile and being in control. This reflects in our latest app design for YelloStrom, one of our big international clients. Letting the user take control over their energy usage was the main goal, while trying to create a fresh and unique user interface.

If the user repeatedly uses too much energy they can increase their monthly payment in an intuitive way which directly shows the outcome in the end of the contract year.
