Features
Everything a word has to offer.
All of this comes with the app. The few things that need Premium are marked at the end.
The word screen
One word at a time, all of it free.
Each word comes with a plain respelling that shows where the stress falls (soo-SUR-us), and your device’s voice can say it aloud. Below it are its definitions, examples of it in a sentence, similar words and where it came from.
None of this is ever held back for Premium.
The daily word
A new word every day, never a repeat.
The daily word is always one you have not seen. Tap “I know this” on any word and it is never offered as your daily word again. A gentle notification can bring it to you at the time you choose.
Search
Search by word, or by meaning.
Look up a word you have heard, or type an ordinary one like “happy” to find rarer words that mean something close to it. It is the quickest way to find a more interesting word for the one on the tip of your tongue.
Topics
Words gathered by subject.
Browse words by topic, from nature to sounds to the feelings that are hard to name.
Tests
Free vocabulary tests, with results always shown.
A short test shows you words of different rarity and asks which you know, with a few meaning checks to keep it honest. You get a score for each test, a history of past tests and an estimate of how many English words you know. Results are never locked.
Favorites and saved words
Keep the words you love.
Heart a word to mark it as a favorite, or save it to come back to. They stay on your device and sync through your own iCloud.
Sharing
Share a word as a card.
Share any word as a typographic card with its respelling and definition, together with a link. The link opens the word in Vocabulum if a friend has the app, or on its own page on this site if they do not.
Offline
Works without a connection.
The word library lives inside the app, so words open instantly on a plane or on a walk. New words arrive quietly in the background when you are online.
No account
Nothing to sign up for.
There is no account and no sign-in, and nothing about you is collected. There are no ads and no tracking. Read about privacy.
iPhone and iPad
One app for both.
Vocabulum runs on iPhone and iPad, with roomier layouts on the larger screen.
Premium, coming
Flashcards, practice games and the Journey.
Vocabulum Premium will add flashcards, practice games and the Journey. They are being built now and will be described here when they are ready. Premium is optional: everything above stays free with the app.
