If your eyes know the sentence but your mouth doesn't, this app trains the gap. 10 lines a day, chunked, blinded, recalled.
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
