Podcasts and live radio

  • Start with suggested and popular podcasts in your language, or a row of live stations chosen by hand.
  • More, at the end of that row, lists every other talk and news station in the language, wherever it broadcasts from.
  • Radio plays about 13 seconds behind the broadcast, so each line is written out before you hear it.
  • Search for any show, episode or station, or paste a link to one. Or open an audio file of your own.
  • Keep a show and Home lists its new episodes; keep a station and it moves to the front of the row.

Read along as you listen

  • The transcript is made on your iPhone. For an episode it runs ahead of the audio, so you can read ahead or jump anywhere; for live radio it follows the broadcast.
  • Switch the whole transcript to English when you need to.
  • Slow it down, skip back or ahead, and pick up where you left off. It keeps playing with the screen off.

Tap any word you miss

  • Tap “cru” and you get croire, to believe: every sense in the dictionary, with examples and how it sounds.
  • Tap the sentence below the entry, or any example, to see it in English.

Save words and review them

  • Save a word with the sentence it came from and a few seconds of the original audio.
  • Gather words in lists of your own, and export them as a CSV file or an Anki deck.
  • Saved words come back as cards that play their own clips.
  • Get a word right and it returns after a day, then three days, a week, three weeks, and every two months after that. Miss it and it returns tomorrow.
