For people whose mouth doesn't quite catch up with their head. You've studied English for years, but the words won't come out. The problem isn't your level — it's that you've only seen them, never said them. IpYoungJak ("입영작") trains the gap between knowing a sentence and saying it. You don't memorise. You make it stick to your mouth. ■ The 5-step daily loop (10 sentences) 1. LISTEN — native audio, twice if you want. 2. SHADOW — record yourself, listen back, self-check. 3. CHUNKS — break the sentence into meaning units and bite each one. 4. FULL — say it in one breath. 5. BLIND — the Korean prompt only. Pull the English out of your mouth, not your head. ■ Spaced repetition that schedules itself Once you've worked a sentence, it returns at D+1, D+3, D+7, D+14, D+30. You don't manage it — you just open the app and tap "Start today's training". ■ Drama mode (Level 3+) A line you memorise as a "problem" doesn't stick. A line you memorise as a "scene" does. Drama mode hands you a situation and an emotion, then asks you to perform the line. Your body remembers what your head won't. ■ Reminders that sound like a coach, not a notification - Morning: today's 10 sentences - After lunch: 3 weakest lines, 3 minutes - Commute: blind retrieval test - Before sleep: one-minute close-out ■ Content tiers - Level 1: survival (I'm starving / Take your time) - Level 2: emotion (I didn't mean it that way) - Level 3: relationship & work (Let me check and get back to you) - Level 4: drama-style lines (I thought you'd understand) ■ One-time lifetime unlock (no subscription) - 10 new lines/day (free is 3) - All levels unlocked - Automatic spaced repetition - Drama mode - Free content updates ■ Privacy Everything stays on your device. No backend, no ads, no IDFA, no third-party analytics. Recordings live in a temp folder and self-delete. — 10 lines a day. Memorise with your mouth, not your eyes.

This is reinforced through a 5-step learning loop and spaced repetition to embed phrases effectively. ### How does the 'drama acting mode' in 입영작 work? Available from Level 3, this mode encourages users to speak sentences with emotion and context, like an actor delivering a line. The goal is to make the language memorable through physical and emotional engagement, rather than just rote memorization. ### What are the benefits of the '평생 이용권' (lifetime pass) in 입영작? The lifetime pass, a one-time purchase, unlocks daily training of 10 sentences (free users get 3), unlocks all sentence packs, enables automatic spaced repetition, grants access to the drama acting mode, and includes free updates for new content. ### Does 입영작 offer offline access? The description emphasizes that all learning data is stored locally on the user's device, implying that core functionalities like practicing learned sentences should be available offline. However, specific details on offline content access are not explicitly stated. ### How does 입영작 handle user privacy? 입영작 prioritizes user privacy by storing all learning data exclusively on the user's device, with no external servers. It also states there are no advertisements and no use of tracking identifiers like IDFA. Recorded audio is temporarily stored and automatically deleted. ### What is the update frequency for 입영작? The app was last updated on August 12, 2026, with version 1.1.0 released on June 6, 2026. This suggests a relatively active development cycle, with new content and features being added regularly. ### What are the different content levels available in 입영작? 입영작 offers content in four levels: Level 1 for survival conversation, Level 2 for emotional expression, Level 3 for relationship and workplace dialogue, and Level 4 for drama-like lines. ### Can I track my progress in 입영작? Yes, 입영작 provides progress tracking features. Users can view their consecutive learning days, the number of sentences mastered, and their weekly memorization success rate. A daily log allows users to note expressions that were difficult to recall. ## Version history (last 2 releases) ### 1.1.0 — 2026-08-12 100 sentences became 320. • Travel (40) — airports, hotel check-in, ordering food, directions, taxis, shopping, and lost luggage. • Work (60) — meetings, email, calls, scheduling, and the conversations nobody wants to start. • Feelings (60) — comfort, apology, arguments, and the things you've been holding onto. • Drama (60) — TV-dialogue tone, built for the acting mode. • Recordings are actually saved now. Your takes collect in the History tab and play back any time. • Write and edit your one-line journal any time from the History tab, even if you stop training halfway. • Sentences matching the goal you picked during onboarding come first, and the 30-second check now sets your starting level. • Drama acting mode works during the 7-day trial. • The trial now introduces 5 new sentences a day, so you don't run out before it ends. • Fixed an issue where purchases could not be completed. • Fixed the privacy policy and terms links in Settings. • Added "Send feedback" in Settings.
