IELTS Chunk Speaking helps you practice speaking answers by building them in short, focused chunks. Instead of trying to produce a long answer all at once, you can practice each role of your answer step by step for Part 1, Part 2, and Part 3. Key features: - Part-based speaking practice - Chunk-by-chunk answer building - Recording and transcription - Feedback based on text you review and confirm - Question pool and random practice - Progress tracking for review Audio recordings are stored on this device and are not sent to the server. When you request feedback or create questions, the text you reviewed or edited, the question text, your answers, and the information needed for scoring are sent to the server. This app is not an official or endorsed IELTS app.
Chunkbook

Chunkbook turns the phrases you could not say in conversation and the foreign sentences you come across into "your own AI phrasebook" and keeps them in review until you can say them. ■ Adding phrases is easy Paste, speak or write. AI analyzes the sentence in about 10 seconds and creates a natural example sentence and the phrases worth remembering. Sentences you write yourself are corrected on the spot and your original text is kept. ■ Review quiz right before you forget Anki-style spaced repetition (SM-2) sets the next due date for every card. A few minutes a day is enough. ■ Instant Speaking gets it out of your mouth See the meaning and say it out loud within the time limit. Phrases you could not say come back until you can. AI checks your speech and records what you said and what you could not say. ■ Listen and shadow Play the translation and the target language back to back. Background playback is supported and you can control it from the lock screen, so your commute or chores become study time. ■ One question a day A question tailored to your phrasebook arrives once a day. What you could not say becomes study material and comes back a few days later. ■ 4 languages, 12 pairs Choose any pair from Japanese, English, Chinese and Korean. Switch phrasebooks and study several languages side by side. ■ Ready to use from day one Starter packs by genre (daily conversation, business, travel) let you start today. Anki decks (.apkg) and CSV files can be imported, and you can export from Chunkbook whenever you want to take your cards elsewhere. ■ Widgets and review reminders Home screen widgets show what is left today and your streak. You can also set the time of your review reminder. Chunkbook has two plans. The free plan keeps manual phrase entry and review quizzes unlimited, and one question a day always arrives. AI features on the free plan cover 10 sentence analyses, 10 Instant Speaking questions and 30 speech checks per month. If you want to study more, the Standard plan (¥780/month, tax included: 100 analyses, 100 Instant Speaking questions, 300 speech checks) is available. * Text on pages that require a login, or private social media posts, may not be available when importing through the share sheet. ■ Subscription details ・Name: Chunkbook Standard (auto-renewable subscription) ・Length and price: 1 month, JPY 780 (tax included) ・Auto-renewal: The subscription renews automatically unless it is canceled at least 24 hours before the end of the current period.
