This is free software. Timetable line-up is based on data from festival organizers.
Application can work in off-line mode, it just downloads timetable data once (aprox. 5kB) when running for first time and saves it to device memory.
Application is able to download updated data according to changes and additions from organizers, they obviously have some surprises in line-up they won't share with us. Use the Menu button and Refresh for 'Now screen' update and Update data for timetable data update.
