Sixty cards, each with the word, its part of speech, a B1 definition, an example sentence, and two typical collocations on the back — an outdated browser, update the app, sign up for free. Rate each card “I knew it” or “Still learning” and your ratings are saved automatically.

Eight gap sentences that ask for a different form of a word you have just met: subscribe becomes subscription, publish becomes publication, react becomes reaction, delete becomes deletion. The endings -tion and -ion do most of the work in this topic.

Ten pairs from real online life: go viral, connect to the wifi, a broken screen, an outdated browser, forget your password, adjust your settings, a catchy headline, listen to a podcast.

A mix of multiple choice and fill-in-the-blank, with an explanation after every answer, right or wrong. Your best score is saved automatically.

Most learners already recognize app, screen and wifi. What they cannot yet do is upload, back up, log out, plug in and shut down without stopping to think. Spend your time on the verbs in this deck, not on the nouns you can already name.

Log in, log out, back up, switch on, switch off, sign up, look up and shut down are two words as verbs but usually one word as nouns: a backup, a login. The difference is invisible when you speak and very visible when you write.

Viral, outdated, user-friendly, wireless, online and offline are what let you have a view about technology rather than only naming it. A user-friendly app and an outdated browser say far more than a good app and a bad browser.

After you finish the flashcard deck, it automatically rebuilds itself from just the words marked “still learning.” A short second pass on the hard ones is worth more than repeating the whole deck.

Explain one thing you did on your phone today using three words from this module — back up, subscribe, notification, settings. Saying “I turned off notifications in the settings” out loud once beats a second pass through the deck.
