Flashcards you type.
Draw a card, type the answer, and QIZU tells you on the spot whether you were right. No flipping the card over. No grading yourself.
Typing is what makes it stick.

Draw. Type. Know.
The app does the checking, so “I basically knew that” can’t quietly become “close enough”.
-
STEP 1
A card comes up
The ones you keep missing and the ones you’ve barely seen come up more often. That is the entire scheduler.
-
STEP 2
You type the answer
Not a tap, not a flip. Producing the answer from memory is the part that does the work.
-
STEP 3
You find out at once
Mint for right, magenta for wrong — and when you miss, the answer you were after, right there on the card.
No schedules. No due-date pile-ups.
Every card carries a weight built from how often it has been asked and how often you got it wrong. New and difficult cards surface more often; the ones you have mastered step back — but never disappear. Nothing is ever due, so nothing can pile up while you are away. Open the app, practise as long as you feel like, stop whenever you want.
How the next card is picked
Each card’s weight is 1 + 8 × failure rate + 4 × novelty,
with the failure rate smoothed so a brand-new card starts at “coin flip” rather
than “perfect”. In practice a new card turns up about five times as often as a
mastered one, and a card you keep missing about four times as often.
Nothing ever reaches zero — the floor guarantees every card in the pool keeps a real chance of appearing, which is why mastered cards quietly come back around instead of vanishing. And no card repeats within five consecutive draws.
What counts as right
Typing is judged strictly on the letters that matter and generously on
everything else. Extra spaces, capitalisation and bracketed hints are ignored.
On a Pinyin side, tone marks are folded away — and v stands in for
ü, the way every pinyin keyboard works. A stored answer can list
alternatives separated by a semicolon, and any one of them counts. Typed Chinese,
Japanese or Korean doesn’t have to reproduce the stored spacing.
There is no fuzzy matching: a real spelling mistake is a miss. But if you typed something that was right anyway, one tap counts it as correct — and that undoes the miss everywhere, in the card’s own record as well as the day’s statistics.
| Stored answer | You typed | |
|---|---|---|
| 你好 (nǐ hǎo) | 你好 | right |
| to go [movement] | TO GO | right |
| nǐ hǎo · Pinyin | ni hao | right |
| nǚ rén · Pinyin | nv ren | right |
| car; automobile | automobile | right |
| Ich weiß · German | ich weiss | wrong |
Type it, tap it, or turn it over.
Choose per set and switch whenever you like. All three feed the same card statistics and the same streak.
-
Type
The full-effort one, and the reason QIZU exists. You write the answer; the app grades it.
-
Choices
Four options drawn from your own cards — and never a second right answer hiding among them.
-
Self-check
Tap the card and it turns over. Knew it, or didn’t — for the days when typing is too much.
A session that fits the moment.
Ten questions at a bus stop, or an endless session on the sofa.
Narrow the round to the cards you keep getting wrong, or the ones you have barely seen.
Where the four options come from
Distractors are other answers from the set you are practising, so they are always the right kind of thing — same language, same script. They are ranked by how plausible they look beside the real answer and sampled from the closest handful, so two encounters with the same card rarely offer the same four.
Anything that could also be correct is excluded: if a card’s answer is
car; automobile, no option matching either word can appear. And when
a set is too small to offer three good distractors, the question simply shows
fewer options — it never quietly turns back into a typing question.
A standard word list, or your own.
Start from an exam vocabulary in two taps, or paste a list straight out of a chat message. Either way the cards are yours from that moment on.
Your first list is free, whatever its size.
Lists download on demand and then belong to you — edit them, merge them, export them. The starter list’s cards don’t count against your own card limit either, so a 2,500-word HSK 6 is a perfectly reasonable place to begin.

Offline, then synced
Sign in once; after that it works on a plane. Cards, progress and statistics sync across your devices whenever you’re online.
A card can have three sides.
汉字 / Pinyin / English. Or term / formula / worked example. Or a word, its article and its plural.
You choose which side asks and which side you answer — in any direction, and you can change your mind before every session.
Ask any side · answer any other
A streak worth keeping.
One answered card is a day. The flame does the rest — and it forgives the day you miss.
Eight colourways on the way to two years, walked as one continuous heating-up — and from a week in, the number beside the flame starts to glow too.
-
Streak freezes
Miss a day and a freeze bridges it for you — no button to press. One a month, three with QIZU+.
-
One evening nudge
At a time you pick, and only when the day is still empty. Turn it off and it stays off.
-

Cards, minutes and accuracy per day, week, month, year — right and wrong stacked in one bar.
Bright, flat, and out of the way.
One screen at a time, never more than a tap from home. No ads anywhere, at any tier.
QIZU+ — 100 sets and 10,000 cards, the whole ready-made catalogue, groups that practise several sets as one pool, and three streak freezes a month. Monthly or yearly.
