ECOplay, the mobile application that helps you save energy, is available for free download - for iOS
and Android smartphones. The application aims to help people change certain small daily energy habits that can make a difference from a financial and environmental perspective. The ECOplay was developed in the framework of the European project FEEdBACk, where the Photovoltaics Laboratory (PV-LAB) at École Polytechnique Fédérale de Lausanne (EPFL) has led the development of the energy monitoring, forecasting, and optimization algorithms embedded in the app.


At a time when many families are teleworking, the energy bills reflect the changes in their habits. This application allows you to learn a little more about energy efficiency playfully while encouraging users to save energy in their daily activities. Moreover, all the saved electricity has a positive impact on reducing the consumption of fossil fuels to produce electricity, minimizing CO2 emissions, and contributing to curb climate change.

In the mobile application, users have access to informative videos and a series of episodes on lighting, heating, or appliances and surveys on day-to-day decision-making regarding energy-efficient behaviors. In the most advanced application levels, users can find a series of six episodes with elements of science fiction and suspense, where the environmental crisis is the central theme. Depending on the learning progress and the users’ performance, the app will award points and achievements, allowing them to progress in the ranking. Throughout the game, users also receive notifications that encourage them to adopt more sustainable behaviors.

The application is available in four languages (Portuguese, German, English, and Spanish) in six countries: Portugal, Spain, Germany, the Netherlands, Switzerland, and Denmark.

The application was developed within the scope of the European project FEEdBACk, whose objective is to develop, integrate and test new technologies related to the energy field, and apply them to promote energy efficiency through a change in users' behaviors.

INESC TEC is the leader of the project, which includes eight partners from seven countries: Technische Universiteit Delft (Netherlands), PV-LAB at Ecole Polytechnique Federale de Lausanne (Switzerland), DEXMA Sensors SL (Spain), Limetools LTD (United Kingdom), IN-JET APS (Denmark), Kreis Lippe der Landrat (Germany) and Estudi Ramon Folch i Associats SL (Spain).

This project received €2.3M funding within the scope of the European Union's Horizon 2020 Research and Innovation program - agreement number 768935. The project will end in April 2021.
