Features

Everything from Toledo, and a few things it can't do.

Tolly shows the same courses and files you see on Toledo, and keeps them on your phone so they open at once, with or without a connection.

Know where your next class is

Each course gets an icon and colour. Tolly shows which one you have class in right now, until when, and in which room.

All the course content

Folders, learning modules, pages, files and links, as in Toledo. Tests and assignments open in the app without signing in again.

A course's content: a learning module with lecture slides, a folder and the syllabus

Lessons and deadlines together

Your KU Leuven timetable and Toledo's deadlines in one agenda, as a list, a day or a week.

Announcements you won't miss

Per course or all together, with an unread filter, swipe to mark as read, and notifications if you want them.

Announcements from all courses, unread ones in bold

Grades

Per course or all at once, with feedback.

Recordings

Course recordings in a built-in player.

Downloads

In the background or a whole course at once, copied to Downloads/Tolly if you like.

Offline

Everything you've opened stays available without a connection.

Two looks

Material or Liquid Glass. Your pick.

Switch in the settings, or shake your phone. Both come in light and dark.

Material 3 Expressive

Rounded, grouped lists, tonal colours and Android's dynamic colour from your wallpaper.

Liquid Glass

After iOS 26: a floating glass tab bar with a lens you can drag, and glass buttons over the content.

Tablets and foldables

Room for two panes.

On a tablet or an unfolded phone, the list and its details sit side by side. Drag the divider to resize them, or fold a pane away.
