Features
Flip, fold, peek, listen, type, or hand the phone to a friend: they are presentations of the same scheduled review, and every one of them ends in a rating the scheduler can use. Items marked at launch are being built and are not in the current test build.
Apple's rule for folding phones is ours too: every pose adds something, no pose is required. Each moment below has a tap, a button and a single-screen equivalent.
The question on the closed outer display. Open the phone and the answer page lands from the hinge onto the right half, with the question on the left and the grading buttons under each thumb. Rate, close, next. It is on by default on Duo, and it never grades for you: an unrated card stays revealed when you close the phone.
A left-hand setting mirrors the grading buttons so Got it sits under the left thumb.
Drag toward the answer to glance at it, and let go to put it back. Drag further, or flick, and it is revealed with the rating buttons. On the open Duo the drag goes toward the hinge, like lifting a page; in laptop posture the cover slides down toward you; on a single screen the card turns under your finger. A long press glances; tap or the space bar reveals; a Hide answer button steps back.
Open the phone flat between two people. Each half turns to face its person: the question toward you, the answer, Hint, Missed and Got it toward your friend. Both halves take touch at once. Your friend grades; the grade becomes your rating, and you can undo it. Close the phone and the session continues solo on the outer display.
Your friend installs the free app, you bring the phones together, and theirs becomes the quiz controller: answer, hint, grade, skip, read aloud. Only the current card travels between the phones, over a direct, authenticated local connection. Nothing of yours is stored on their phone afterwards.
Works on every iPhone at both ends. No Duo required.
Pass the phone at launch
One phone, any iPhone. Hand it over; your friend sees the question and lifts a cover to see the answer, reads the question aloud, and grades. It is the quiz every student already does with paper, with a schedule behind it.
Half open on a desk, the question sits on the raised half in large type. Once revealed, the answer and the rating bar sit just under the fold, and the explanation under them, so your hands never leave the lower half.
The fastest card is one you did not have to type.
Text is recognised on your phone, and longer passages use cloud AI. Short passages will also become question-and-answer cards on your phone, with Apple Intelligence. on-device at launch
Chapters and lecture decks become cards with page references. In laptop posture the page is on the far half and the cards land on the near half. Marking each card with the sentence it came from is next. marks at launch
Paste a paragraph and get cards, or cloze suggestions you accept with a tap. Speak a snippet and it is transcribed on your phone first. voice at launch
Cards appear one at a time, as small index cards you keep or skip. If the connection drops, the cards you already have stay.
Hide a word in a sentence, or mask a region of a diagram. Basic occlusion is free; unlimited regions are part of Pro, and so will be a quality check on AI batches. free tier and quality check at launch
Bring in .apkg and .colpkg files, including the newest compressed format. Review history, media and sub-decks come along, and re-importing updates instead of duplicating.
Cloud results can be wrong; they stay editable, and the source stays a tap away. Every AI result will carry a label: On-device, Cloud, or Note when a person wrote it. labels at launch
Cards read aloud with AirPods in, a voice per card language, and hands-free rating by tap. Eyes on the road.
Due count, streak and exam countdown on the Home Screen and Lock Screen. StandBy on either Duo display. StandBy at launch
An active session on the Lock Screen: cards left, streak, tap to resume.
"Quiz me on Bio 101." "How many cards are due?" Courses and cards as Shortcuts entities.
Search a card from the Home Screen and open it where it lives.
Your cards, media and review history on every device signed in to your Apple Account. Local first; the phone is the source of truth.
