The most important way to promote sustainable living is through

education and awareness-raising by disseminating information

through different media. International organizations and NGOs

have proposed several solutions. One of these is the AWorld, a mobile

app that provides clear and accurate information from reliable

sources. This app seeks to change its users’ habits and mindset to

save the planet through its multiple functionalities. However, could

be considered AWorld an educational mobile app for promoting

sustainable living in university students? This paper reports the

results of the pedagogical and user interface usability evaluation of

the AWorld. Twenty-five experts conducted the assessment. They

evaluated the app through a questionnaire to value the quality of

mobile learning apps. Results indicate that the AWorld app could

be considered a potential resource to learn and commit to leading

sustainable, healthy lifestyles and address problems such as climate

change in higher education environments.
