Tethera Study
Notes that know what's due
Free · Designed for iPad. Not verified for macOS.
Find your school, paste your token, and every Canvas deadline lands in one list — or add your courses yourself. Hear what's due tomorrow the evening before.
Tethera is a handwriting notebook built around your coursework. Connect Canvas, or add your courses yourself, and every course gets its own notebook and every deadline is sorted by how much it's worth.
- The evening before anything is due, Tethera tells you what's coming — and any task can have its own alarm.
- Record the lecture while you write, then tap any word to hear what was being said.
- Import a lecture PDF and write straight onto it — your ink is a layer, and the original slides stay untouched.
- Your notes are encrypted end to end — nobody can read them, including us.
WRITTEN FOR APPLE PENCIL
A pressure- and tilt-sensitive ink engine with a fountain pen, ballpoint, pencil and highlighter. Lasso to move, resize and rotate your writing. Zoom in close or out past the page. Photograph a slide straight onto the paper and write over it.
YOUR DEADLINES, WEIGHTED
Tethera reads your courses and due dates from Canvas and sorts them by what they cost you, not just by date. Break a deadline into steps and mark where each one is handed in — Canvas, Gradescope, Coursemology, wherever your course puts it. Add tasks of your own that Canvas will never know about. Set a task to repeat — weekly readings, fortnightly problem sets — and the next one appears as you tick the last one off. Subscribe to your deadlines in Apple Calendar or Google Calendar.
NOTES TIED TO THE WORK
A note is linked to the assignment it belongs to, not just filed near it. When Canvas forgets an assignment, your notes on it stay readable.
SEARCH YOUR HANDWRITING
Find a word you wrote by hand. Recognition runs entirely on your iPad using Apple's built-in text recognition — what it reads never leaves your device.
PRIVATE BY DESIGN
Notes are encrypted on your device before they are backed up, with a key kept in your iCloud Keychain. Your Canvas access token never leaves your device. Tethera has read-only access to Canvas: it never submits work, posts comments, or changes anything in your courses. No ads, no tracking, no analytics.
WORKS WITHOUT AN ACCOUNT

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
- Find your school by name. Connecting Canvas no longer asks for a web address — search for your school, pick it, paste your token. Works for any university on Canvas.
- More reliable Canvas. Disconnecting now removes everything, even mid-sync, and your notebooks stay filed under their courses when you reconnect.
- Small things. "Add courses myself" works on its own, sample data has a Remove button right on the Tasks list, and long lists of finished tasks tuck away behind "See all tasks".
- Sharper PDFs. Imported slides and handouts are now as crisp as your handwriting, on iPhone especially, and stay sharp when you zoom in.
