Everything you owe, in the order it'll hurt.

Click the bar. The next ten things due, colour-coded by how soon. One more click opens any of them in Canvas.

No login. Ever.

It reads the calendar feed Canvas already gives every student. Nothing to sign into, no permission from your school.

02
Works on the train.

Offline, it keeps the last list it downloaded and tells you how old it is — instead of going blank.

03
Never guesses.

If it can't work out exactly when something is due, it doesn't show it. A wrong deadline is worse than none.

On purpose

What it doesn't do.

The only network requests it ever makes are to your own calendar link — and to check for a new version when you press the button.

No account. No sign-up. No email.
No analytics. No tracking. No crash reports.
No subscription. No licence key to lose.
No planner. No to-do list. No AI assistant.

Setup takes about a minute.
