Tip forward — you know it
One word fills the screen. Flip the phone forward and it's gone, with a haptic tap so you feel the answer land without looking.

Know the word.
VocabKuizu is a vocabulary game you play with your hands. Hold the phone up, read the word, and tip it forward when you know it — or back when you're not sure, and see what it means.
Free on iPhone and Android. No account, works offline.

Built for the way vocabulary actually sticks
How it plays
No tapping. No typing. Just the word and your hands.
A round is fifteen words and about a minute. It feels like a game because your whole body is in it, not just your thumb.
Tip back — not sure
Not sure isn't failing. The definition stays up for two to five seconds — you choose — and the word comes back later in the round while the answer is still fresh.
Finish with a study list
At the end you get the words that never landed, with their definitions — the most useful thing on the screen, and the reason this is study and not trivia.
Your lists
Paste a list. Play it thirty seconds later.
Typing fifty words on a phone keyboard is a hundred text fields, and nobody does that twice. So don't.
- Paste anything. Tabs, commas, dashes, colons, or word-then-definition on alternating lines — it works out the format itself.
- Handouts survive. Numbered and bulleted lists lose their markers, and definitions keep their own commas.
- It tells you what's wrong. Duplicates, words too long to read while tilting, definitions that'll get cut off — flagged before you save, never silently dropped.
- Common words fill themselves in. For 360 school and test words — analyze, photosynthesis, perpendicular, suffrage — each card arrives with the word's roots, its prefixes and suffixes, and several example sentences, a different one each time it comes round.
- Three lists free, up to 40 words each. One purchase, no subscription, raises that to 50 lists of 1,000 words.
What is included
Three decks, 454 words, all offline.
Every word carries its root and origin — press and hold the word to see it. Or paste your own list and play that instead.

What it actually looks like.
Real screens, landscape, exactly as the game is played.
Honest scoring
Your score counts first sight only.
Most flashcard apps take your word for it. That's how you end up feeling ready and then blanking on the day.
Not sure is trusted. Claiming isn't.
Admitting you don't know a word is reliable, so the word comes back later in the round and anything still unknown lands on your study list. Saying you knew it scores, but only on first sight.
Recovered words don't pad the number
Get a word on the second pass and it's reported separately, not folded into your percentage. The honest figure is the one measured before you saw the answer.
