It also provides personalized tips and carbon offset projects to promote tangible climate actions that can reduce pollution as well as save money. Lastly, this app features a social network functionality, with which users are encouraged to share, compete and collaborate with their friends and neighbours, and stand a chance in winning monetary/prizes rewards.
