水 MUJI Life is an iPhone app developed by RYOHIN KEIKAKU Co. Ltd. It is a lifestyle app that aims to promote environmental awareness through water consumption. With the urgent issue of plastic waste, the app encourages users to rethink their habits and find ways to reduce their impact on the environment. Rather than disposing of plastic bottles after each use, the app suggests refilling them to minimize waste.

The app provides information about water supply points, not only in MUJI stores but also in public locations. Users can easily locate places where they can refill their water bottles, making it convenient and accessible to make sustainable choices.

In addition, every time users refill their water bottles, the app calculates and displays the amount of water consumed, the number of plastic bottles saved, and the reduction of CO2 emissions. This feature allows users to track their contribution to the environment and encourages them to continue making eco-friendly choices.

With 水 MUJI Life, users can take small steps towards a more sustainable lifestyle while raising awareness about the importance of reducing plastic waste.
