Distinction 2000 - Core Vocab
Build reading & spoken English
Only for iPhone
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
First chapter free, offline. Build reading and spoken English with natural examples, slow & natural audio, 40 academic + 40 snapshot topics. No ads, one-time.
You know the basic words, but longer texts still feel hard —
and the right words still don't come when you need them in conversation.
Distinction 2000 is an English learning app that helps you turn the words
you already know into reading ability and real conversation.
It combines academic English and practical everyday English in one balanced
learning experience. Instead of stiff textbook sentences, it teaches core
vocabulary through natural, practical examples created with ten native speakers.
Includes 2,000 headwords, 6,554 total entries including related words and idioms,
2,442 example sentences, 40 academic reading topics, and 40 snapshot topics.
It helps you build not only vocabulary, but also the background knowledge
that makes reading, listening, and communication easier.
