How PolyYapp works
PolyYapp does one job, Dutch vocabulary, in five parts. Each has its own page with the details, the limits and a screenshot.
Spaced repetition
Every lesson is filled first with the Dutch words due for review, then topped up with new ones. Each word climbs its own review schedule.
Exercises
5 exercise types, from recognising a Dutch word to typing it from audio and filling it into a sentence. Harder ones unlock per word.
Your own words
Search the Dutch dictionary, add the words you meet in real life, and they join the same review schedule as everything else.
Daily word game
Guess-a-Word: one hidden Dutch word a day, the same for everyone. Ask yes-or-no questions in Dutch and an AI game master answers.
Learn in your language
Study Dutch straight from English, Spanish, French, Polish, Russian, Turkish or Ukrainian: one setting changes the app and the meanings.
