8 tracks, one method: sixteen at a time, active recall, and a Blocks break between answers.
Every track has a free sample. Basic opens all of it, in every language.
A learning loop designed around how memory really works — small sets, active recall, and a game that keeps you coming back.
Flashcards resurface the words you keep missing on the perfect schedule — so review time is never wasted and words become permanent.
Play Blocks between answers — the play-and-recall loop burns each word into long-term memory instead of cramming.
Say your answers aloud — words, sentences and whole lines — and hear native recordings where we have them.
Prove it in timed 16-item tests on every track and keep your streak alive — show up 5 minutes a day and watch retention compound.
Download your topics and keep practising on a plane, the metro, or anywhere with no signal — your progress syncs the moment you reconnect.
Every correct answer banks 3 blocks — every 6 words you cash them in. The break between answers is the spacing effect doing its quiet work: that is how words become permanent.

Pick a language pair, type the answer, take a Blocks break — in 10 seconds.
Three steps, endless levels.
Every session is exactly 16 — words, sentences, dialogue lines, travel phrases or sayings — about 5 focused minutes. Small enough to finish, big enough to add up fast.
Active recall plus a Blocks break between answers moves each one from "just saw it" into memory that lasts.
What you miss comes back until it is yours. Pass a timed 16-item test to prove it, then move on.
Most apps count lessons completed. We track recall — whether a word is still there 7, 30, and 90 days after you learn it. Here’s how 16Word is doing, live.
One loop pulls a word back out of memory; the other locks it in during the game break. Fire both together and the word stays — that’s the whole method.
You retrieve every word instead of re-reading it — and retrieval, not review, is what actually builds memory. So each minute of practice counts for far more.
Words resurface right before you’d forget them, then stretch further apart each time they stick — so more of what you study lands in long-term memory.
Blocks breaks fire your visual-spatial memory alongside verbal recall. Two mental codes for one word means far more to grab it by later.
Around 6,000 hand-checked words per language, plus sentences, dialogues, travel situations, proverbs and idioms — pick the language you speak and the one you want, in any combination.
Climb the ladders — every streak and every game counts.
