アルプスの少女ハイジ とくとくウォーキング is a lifestyle app designed for iPhone users that encourages physical activity through a fun and engaging experience. Users embark on adventures with beloved characters from the Heidi series, collecting milk points by walking or traveling. The app operates on a straightforward three-step process: users go out with Heidi, collect milk when their cans are full or flowers bloom, and exchange the milk for points.

The app tracks movement, rewarding users with milk cans for every 10 kilometers traveled, regardless of the mode of transportation. Additionally, users can earn milk by walking, completing quizzes, reading QR codes, and achieving various challenges. Customization options allow users to exchange collected milk for unique characters and backgrounds, enhancing the overall experience and personalizing their point-collecting journey.
