Miivo is a multimodal mobility application that aims to unify all the sustainable mobility options of a city in a single app. Our goal is to allow every citizen to plan, book and pay for their trips in their smartphone no matter the transport mean they choose. Moreover, we will implement an interactive gamification system that will reward our users as they contribute to reduce their CO2 emissions and be part of a whole mobility community (challenges, rafles, prizes, rewards…).
