ZEN is a free Android application that encourages users to earn points through walking while engaging with friends. Unlike traditional point-earning apps, ZEN combines social interaction with fitness, allowing users to accumulate coins by walking together. The app's unique feature is its ability to track friends' locations, enabling users to complete missions together and earn more points. Users can also earn 1.5 times the usual coins when walking with friends, making it a fun and collaborative experience.

In addition to walking, ZEN offers various ways to earn coins, such as watching video ads and completing daily missions. Users can exchange their accumulated coins for popular rewards, including T-points, Amazon Gift Cards, and more. The app is designed to continually evolve, with new missions and rewards expected to be added. ZEN effectively combines social networking with fitness, making it an engaging platform for those looking to stay active while earning rewards.
