SpaceY登月计划 - 爬楼减脂 is a lifestyle application designed for iPhone users. The program focuses on a virtual moon-climbing challenge where users collectively aim to cover the distance from Earth to the Moon, which is approximately 384,403,900 meters, burning 320,336,575 kilocalories in the process.

To achieve this task, teamwork is essential as an individual would require around 10,678 years to complete the challenge alone. The app aggregates stair-climbing data from all members daily, and the mission ends once the total progress reaches 100%.

Participants can earn rewards such as "满月" and "星云" by meeting daily moon-climbing goals, which can be used to customize their virtual universe with "星座" and "星云." The app offers features like AR functionality for taking photos with the customized universe.

Users can engage in challenges and competitions through national, city, and team leaderboards to earn medals based on accumulated stair-climbing levels. Additionally, they can join global teams for mutual support and motivation towards achieving the moon-climbing target.
