Get ready for CELPIP and TCF with practice tests that work like the real exam. Learn French one real sentence at a time. Review your words until they stick. PRACTICE TESTS FOR CELPIP AND TCF • Listening, Reading, Writing and Speaking, in the format of the real test. • Practise one section or one part at a time, or sit a full mock exam with real timing. • Each exam is put together from our question bank, so you keep meeting new topics. • Reading and Listening are scored as soon as you finish. Writing and Speaking get AI feedback that shows what to fix next. • See your estimated CLB (CELPIP) or NCLC (TCF) level, and follow your progress for each skill. • Learning mode is untimed: translations are on, and you can tap any word you don't know. FRENCH PRACTICE, ONE SENTENCE AT A TIME • Real beginner (A1) French sentences. See the sentence and say what it means, see the meaning and write it in French, or just listen. • After each answer you get the full breakdown: every word, where the verb form comes from, its full conjugation and the rules the sentence uses. DECK REVIEW • Every word you save becomes a flashcard, and spaced repetition decides when it comes back. • One clear number tells you how many cards are waiting today. • Rate each card from Again to Easy, and the next review is scheduled for you. • Auto-Review reads your cards aloud, hands-free, while you cook, commute or rest your eyes. STORIES TO READ • Short stories from A1 to C2 in English and French, and story series told in seasons, episode by episode. • Tap any word to see what it means and save it to a deck, or have a paragraph read aloud. EASY ON THE EYES • Large, clear text throughout, with a text size you can change while you study. • Arabic and Persian read right to left, in a typeface made for them. Practice tests are free to take. On the free plan, AI scoring for Writing and Speaking has a monthly limit.

Pause a podcast to look up a word? Never again. Unpack is a podcast player that listens with you. When you hear a term you don't know, ask Siri or shake your head with AirPods on and get a definition that's right for the conversation. "UGC" in a marketing podcast means User Generated Content, not Uganda. Unpack already knows. HANDS-FREE, IN THE MOMENT • Say "Hey Siri, define that in Unpack." Works with the screen off, phone in your pocket. • Shake your head with AirPods Pro, Max, 3, or 4 to trigger a definition. Nod or shake to navigate. Hear the answer spoken back. • Built for driving, cooking, running, and the gym, when picking up your phone isn't an option. • Tap any word in the live transcript to define it instantly. DEFINITIONS THAT FIT THE CONVERSATION Generic dictionaries don't know what you're listening to. Unpack reads the transcript around the moment you ask, so the definition matches the topic: economics, biology, marketing, history, whatever the show is about. Same definition quality for free and Premium users. The AI is not a paywall. MORE THAN SUMMARIES AND HIGHLIGHTS Other AI podcast apps summarize an episode or save the good parts for later. Unpack works on the part you didn't understand, while the episode is still playing. Definitions are generated on your device first using Apple's on-device model, so most lookups never leave your phone, and they work without a signal. LEARN, DON'T JUST LOOK UP • Every term you define joins your personal glossary, sorted by subject. • Unpack quizzes you on terms days later, so they actually stick. • See how many terms you've learned and which subjects you're strongest in. • Premium adds comprehension quizzes during playback, checking what you understood and not just what you heard. • Premium highlights unfamiliar terms in the transcript before you even ask, based on what you've looked up before. A REAL PODCAST PLAYER • Subscribe via RSS or import your shows from Apple Podcasts, Overcast, Pocket Casts, or Castro with one OPML file. • Speed control, skip, sleep timer, lock screen and Now Playing controls. • Download episodes for offline listening. • Live Activity and Dynamic Island while you play. PRIVACY-FIRST Your podcasts, your glossary, and your listening history stay on your device. We never see them. Definitions run on-device first. When one needs the cloud, it goes through our proxy with no identity attached, and Settings has a switch to turn that off entirely. Read the full policy in-app. PREMIUM ($4.99/mo, $24.99/yr, or $79.99 lifetime) • Unlimited definitions • Unlimited review quiz sessions • AirPods head gesture trigger • Comprehension quizzes during playback • Proactive highlighting of unfamiliar terms in the transcript Free users get the full podcast player, AI-powered context-aware definitions, Siri triggers, 10 lookups per day, your personal glossary with vocabulary stats, and one review quiz a day. Forever. Try Premium free for 14 days.
