タイテ管理 Stella is a multimedia application developed by Yuya Sasaki for iPhone users. This free app falls under the Music & Radio category and aims to simplify the complexities of festival and large live event timetables. Users can easily navigate through schedules and track their favorite artists' performances.

The app allows users to rate groups with a two-step like system to manage their favorites effectively. It offers filtered views based on the number of likes, displays the current time position on the timetable for quick artist tracking, and enables searching and liking artists directly from the list. Future updates will focus on handling events with multiple stages, such as rock festivals, idol events, and circuit events.
