" MANG MANG - GUIDE DOG TRAINING " is a guide dog training assistant app. Our target users are puppy walkers for guide dogs, who are responsible for caring for the guide dog puppies and familiarizing them with future training content. Guide dog training organizations have expressed to us that they currently rely on manual methods for data organization and scheduling, and are in dire need of an assistive program to reduce their manpower burden. This app will digitize the training content, saving paper and facilitating data storage. It provides a communication and check-in record between the training unit and puppy walkers, as well as integrating training and care items into step-by-step diagrams for puppy walkers to reference at any time. Additionally, it offers various other functions that allow users to plan and record, thereby reducing labor costs, improving training efficiency, and optimizing the user experience.
