Everything you need to actually remember

A learning loop designed around how memory really works — small sets, active recall, and a game that keeps you coming back.

Spaced repetition

Flashcards resurface the words you keep missing on the perfect schedule — so review time is never wasted and words become permanent.

Blocks brain-breaks

Play Blocks between answers — the play-and-recall loop burns each word into long-term memory instead of cramming.

Voice & pronunciation

Say your answers aloud — words, sentences and whole lines — and hear native recordings where we have them.

16-word streaks

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.

Learn offline

Download your topics and keep practising on a plane, the metro, or anywhere with no signal — your progress syncs the moment you reconnect.

Answer. Earn pieces. Play.

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.

How it works

Three steps, endless levels.

STEP 1

Learn 16 at a time

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.

STEP 2

Lock them in

Active recall plus a Blocks break between answers moves each one from "just saw it" into memory that lasts.

STEP 3

Keep them for good

What you miss comes back until it is yours. Pass a timed 16-item test to prove it, then move on.

Our north-star metric, in the open

We measure what you actually remember

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.

81%
remembered after 7 days
62%
remembered after 30 days

gathering data
Backed by cognitive science

Your brain has two memory loops. 16Word trains both.

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.

Active recall
Learn faster

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.

Testing effect · Roediger & Karpicke, 2006
Spaced repetition
Remember 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.

Spacing effect · Cepeda et al., 2006
Dual-loop encoding
Last far longer

Blocks breaks fire your visual-spatial memory alongside verbal recall. Two mental codes for one word means far more to grab it by later.
