FRF19TT is a free iPhone app developed by Ryota Iwai, designed to enhance the experience of attending the Fuji Rock Festival. This multimedia app provides a detailed timetable for each stage, allowing users to plan their festival experience more efficiently.

One of the main features of FRF19TT is the ability to view information about the performers. Users can easily access details about each artist, including their biography, discography, and links to their social media profiles. This feature helps festival-goers discover new artists and stay updated on their favorite performers.

Another useful feature of FRF19TT is the option to create a personalized timetable. Users can add their preferred artists to "MyTable," allowing them to easily keep track of their must-see acts. The app also includes an autoscroll feature, which automatically scrolls to the present time when the clock button is tapped.

FRF19TT regularly updates its timetable data to ensure accuracy and provide users with the most up-to-date information. However, it's important to note that this app is not an official app for the Fuji Rock Festival and the data may not be updated during the festival itself.

Please use FRF19TT at your own risk, as the app does not provide any warranty for the accuracy of the timetable or the content about the performers. For support or further information, you can visit the developer's blog or reach out on Twitter and Facebook.
