The 3-7-14 Mastery System
Three repetition steps — on days 3, 7, 14 — and the word sticks in long-term memory forever. No opaque algorithm, no settings to tune. Just three well-timed reminders.
Without review, memory fades fast. ProWord reviews each word right before you'd forget it.
Learning
A new word, fresh in short-term memory.
Learned
Reinforced on day 3, then strengthened on day 7.
Memorized
Sealed in after day 14 — it's yours for good.
Three words at a time. Across 34 islands.
Every practice session covers 3 words and earns you a paw. Six paws lead to Island Practice — a checkpoint that proves you've learned the stretch. Pass it, and CatDog moves to the next island, where a new house is waiting. 34 islands on the path. It's not a streak counter pretending to be progress. It's a real journey, made of words you've actually practiced.
