Project Overview
SHACHIBOOK is an iOS app developed for fans of the idol group "TEAM SHACHI". It provides functionality to centrally manage information from multiple sources, enabling fans to efficiently collect the latest information from dispersed information sources.
Challenges and Background
Information Fragmentation
Information was scattered across multiple platforms including official website, Twitter, Instagram, and YouTube, making it difficult for fans to keep track of all the latest updates.
Lack of Real-time Updates
There was no unified system for receiving important information (event details, ticket sales, etc.) in real-time.
Poor Mobile Optimization
The existing official website was not optimized for mobile viewing, making it difficult to use for smartphone users.
Solutions and Approach
Information Integration System
Built a backend system that automatically collects and integrates information using APIs from various social media and websites. Users can access all information through a single app.
Push Notification System
Delivers important updates as real-time push notifications. Users can receive important information without missing anything.
Mobile-First UI
Native iOS app designed with smartphone usability as the top priority. Achieved intuitive operations and smooth user experience.
