Keep released version 4.0 in May 10, which completely upgraded the UI and product functions, and put forward a brand-new product vision: Keep is not limited to the fitness field, and what we need to do in the future is to create a "free playground". "On the free sports field, you can find your favorite sports form and participate in it quickly. You can also find like-minded friends to communicate freely, participate in activities together, play together and feel the joy of sports. " Keep 4.0 is equivalent to a brand-new upgraded product from "mobile fitness instructor" to "free playground".

Activity Awards: Cinnamon Roll Medal, Cinnamon Roll Badge, Cinnamon Roll Socks, Cinnamon Roll Blanket. The medals corresponding to different kilometers are different, and the price of the suit is different. Please pay attention to the activity time. You can't exchange medals after the activity time.
