Words worth keeping.
Look a word up, keep the ones that matter, and watch a vocabulary take shape.
What it does
A dictionary, a notebook, and something to show for it.
A dictionary that ships with the app
370,000 words on your phone. Look one up on a plane, in a tunnel, anywhere.
Tags that survive the shoebox
File a word under a book, an exam, a whim. Then find everything you filed.
Insights into what you actually read
Your vocabulary sorted into difficulty bands, and what that says about you.
Research tools
Synonyms with the differences spelled out, rhymes, etymology drawn as a family tree.
Four themes, light and dark
Classic, Neon, Natural, and a Book theme set in Baskerville on warm paper.
Your words follow you
Mirrored to your own private iCloud. Lose the phone, keep the vocabulary.
Pick how it looks
Every theme has a light and a dark mode, and follows your phone.
On privacy
The short version, in plain words.
Your words are stored on your phone and mirrored to your own private iCloud — your storage, your Apple account, not readable by us. Comparing your vocabulary with other readers is off unless you turn it on, and even then it sends five numbers, never the words. Usage statistics can be switched off in Settings, and you can export everything or delete your account from the same place.
