About this app

One word each day. Vocabulary, etymology and pronunciation, in an editorial space made for those who love words.

Oratio is a minimalist app that offers you, each morning, one carefully chosen word. Not just any word: it comes with its precise definition, its etymology, its synonyms, an example of use and its audio pronunciation. A complete editorial experience, designed so each word leaves a trace.

EACH DAY, ONE WORD

— A precise, nuanced definition, without the simplifications of an ordinary dictionary.
— Etymology that connects you to the origin and history of the word.
— Carefully selected and commented synonyms, not listed at random.
— Example of use in literary or everyday context.
— Recorded pronunciation so you know how it sounds.

REINFORCE, PLAY, REMEMBER

Oratio includes optional mechanics to consolidate what you've learned. No pressure, no aggressive timers, no invasive notifications.

— Short daily challenges that review your recent vocabulary.
— Classic games reimagined with your catalogue: Wordle, word search, crossword, anagrams.
— Calendar of consulted words to revisit any previous day.
— Streak system with resilience, rewarding consistency without punishing real life.

THEMATIC LIBRARIES

Beyond the word of the day, Oratio Premium includes curated packs of words grouped by theme. First library available: "Words for speaking of love", a literary selection to expand your emotional repertoire. Coming soon: packs on grief, work, silence and other semantic fields.

ORATIO PREMIUM

A single subscription, with no surprises:

— Complete calendar of consulted words, without time limit.
— Full access to all review modes and games.
— Curated thematic libraries.
— Etymology, phonetics and pronunciation for every word.

Available as monthly or yearly subscription. No deceptive trials, no hidden auto-renewals.

THE ORATIO PHILOSOPHY

Oratio doesn't seek to make you an addicted user. There are no streaks that ruin your day, no aggressive notifications, no advertising, no selling of your data. Just you, one word each day and a carefully designed editorial space.

Designed in Spanish, with a catalogue also available in English for those who cultivate both languages. Made for intellectually curious people, regular readers, writers, language professionals and anyone who believes that precise words still matter.
