On iPhone Duo, open the phone slowly: the answer arrives a little at a time as the hinge opens. Stop as soon as you know it. If the phone is already open, open it a little further, or slide the answer up with your thumb.
On any other iPhone, slide the answer up from the bottom of the card, as far as you need.
Then say whether you know it. Two buttons are there at every moment, and their words follow what you’ve seen:
- Nothing yet: I don’t know, or I know it.
- Part of the answer: I don’t know, or I know the rest.
- The whole answer: I didn’t know, or I knew it.
I know it and I know the rest are checked. The whole answer shows, with a ✓ and how much you revealed (“✓ 4 of 14 letters”). Were you right? Tap Next card, or close your iPhone Duo. If not, tap I was wrong: the ✓ becomes a ✗, and the card comes back soon, as after any wrong answer.
A figure with several labels (an image occlusion card from Anki with a group of masks) asks for each label on its own. Tap the label you’re guessing, then open the phone or slide the answer up: only that label is revealed, and the others keep what they’ve shown. A label revealed whole waits for your answer. I know it and I know the rest are checked against that label, then Next label goes on to the next. The card is graded once, after the last label: right only if every label was.
You never grade yourself. What counts is how much of the answer you revealed before you answered, not how hard the card felt. The less you peek, the later it comes back. Undo takes back any answer, I was wrong included, and so does shaking the phone.
Without the gesture:
- VoiceOver: swipe up on the answer to reveal one more letter, or one more word of a definition. I know it and I know the rest say that they show the whole answer to check it.
- Voice Control, or anyone who finds the gesture hard: turn on ⋯ › Settings › Show a letter button. It reveals one more letter, or one more term, line or part of a rich answer.
- A keyboard: space reveals one more letter. W is the left button (I don’t know, I didn’t know, I was wrong) and R the right one (I know it, I know the rest, I knew it). Once answered, space is Next card.
A new card shows its answer the first time, with the buttons of a whole answer, I didn’t know and I knew it. I didn’t know brings it back as a question in a minute; I knew it, in ten minutes. To test new cards straight away instead, turn off Introduce new cards in the deck’s ⋯ › Deck options.
Formulas with VoiceOver: formulas are spoken as math, as far as their terms are revealed: “x squared”, “a over b”, “the square root of …”, sums, integrals and limits with their bounds, matrices row by row, and chemical formulas such as “2 H 2 plus O 2 yields 2 H 2 O”. A symbol it doesn’t know is said by its name. Code is read line by line.
