Description by Byoungho Kim Written by the developer, not by AppBrain. Click to read.
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.
