I kept installing vocabulary apps and deleting them. The word was never the problem — opening a fifth app was. So verbobum has no app. One word a day lands where you already read messages: email, Telegram or Signal. The word, a short definition, three real sentences. Two minutes, then you're done. - Pick the channel and the exact hour it arrives. Signing up is one email field, no password. - Free: one channel, general vocabulary, pause with one tap. - €8/mo: several channels at once including Signal, plus 10 niche vocabularies (legal, tech, business, science…). - €10/mo: the word and its examples read aloud on Telegram and Signal. Six languages — English, French, Spanish, German, Portuguese, Italian. You can also receive the word in the language you're learning, defined and illustrated entirely in that language. I tried not to overclaim the spacing effect: the three studies are linked on the landing page (Brysbaert 2016, Cepeda 2006, Dong 2020), each with a note on what it does not prove. Two things I'd like feedback on: whether the ten niche vocabularies are the right ten, and whether Signal delivery matters to anyone besides me.
