Version 1.1.2:

Bigger Checklist Widget
A new large widget size that shows six assignments.
How it works: Long-press your Home Screen, add the Assignment Checklist widget, choose the large size, and tap a circle to check something off.

New Timer Sounds
Five new instrument sounds for when your timer ends: Velvet, Ember, Drift, Sunrise and Keepsake.
How it works: Go to Settings → Timer Sound, tap one to hear it, and choose your favorite.

Tidier Classes
Each new class gets its own color automatically.
How it works: Rename or delete a class with one tap, and its assignments update to match.

Smarter Due Dates
New assignments are due tomorrow at 11:59 PM by default.
How it works: Pick Today when it's due tonight. Otherwise you don't need to change anything.

Tips & Tricks
Short looping clips that show what the app can do.
How it works: Go to Settings → Tips & Tricks.

Polish & Fixes
There's a new launch animation and a "Connected" animation when you link your school. Editing now always opens the right assignment, and renaming a class updates its assignments.
