The schedule should be viewable on a mobile device. But there are also alternative exports you can use to consume it from another application.
The Schedule is available through an XML feed. You can use ConfClerk in Debian to consume this, or Giggity on Android.

- F-Droid: https://f-droid.org/repository/browse/?fdid=net.gaast.giggity
- Google Play Store: https://play.google.com/store/apps/details?id=net.gaast.giggity
# apt install confclerk
# apt install confy
which works well on debian based smartphones.
The schedule is available through an iCalendar (ical) feed. Your calendar application should be able to consume this.
