After each iteration and user test, a new wireframe was released, until we got to Sybil final version, now on its way to be published. A thorough work was done to understand the type of data to be shown and the best way to visualise the wealth of information the user is provided with. Beyond the basic functions available in the free version, the app comes with on-line payment services, pre-set scenarios, multi-home and multi-users management.

Sybil takes the user in a simple, empathic and very straightforward way through the delicate journey of learning how to manage energy consumption. Words used, choice of typeface, colours, graphic visualisations and illustrations, contribute to literally relax the user while getting to analyse costs and emissions or managing heating system optimisation and temperature in the house.
