Keep medal activity is an online challenge activity extended by Keep based on the traditional marathon. The activity includes walking, running, rope skipping, cycling and other forms. If you succeed in the challenge, you can get rewards for various creative theme activities. The exclusive series of medals is mainly designed to encourage people to keep fit, exercise, and enhance their physical fitness.

Keep is an app that was launched on February 4, 2015. It is committed to providing one-stop sports solutions such as fitness teaching, running, cycling, making friends, fitness and diet guidance, and equipment purchase. Keep has opened Keepland, an offline sports space, and launched the KeepKit series of smart hardware products, which were named "Selected Apps of 2015" by the App Store.

Keep released version 4.0 on May 10. It has comprehensively upgraded the UI and product functions, and proposed a new product vision. Keep is not limited to the fitness field. What it needs to do in the future is to create a "Free Playground".

On the free sports field, you can find your favorite form of sports and quickly participate in it. You can also find like-minded friends to communicate freely, participate in activities, play together, and feel the joy of sports. Keep 4.0 is equivalent to a new upgraded product in the transition from "mobile fitness coach" to "free sports field".
