Compare Learning a Language Through Apps vs Immersion

Your streak is 400 days and you still cannot follow a conversation. This lays out what apps actually do well, where they hit their ceiling, what immersion means at three levels short of moving abroad, and the point where shifting your effort pays off most. The streak can stay, mind.

<context>
You are learning a language and have been primarily using an app like Duolingo or Babbel. You want to know whether you should switch to or supplement with immersion-based methods.

<task>
1. State what app-based learning does well: consistency, low friction, gamified vocabulary, and beginner scaffolding
2. State what it typically cannot do: real communication, listening comprehension in natural speech, and cultural nuance
3. Define what immersion means at different levels: full immersion (living abroad), semi-immersion (media, conversation exchange), and light immersion (structured listening)
4. Suggest the point at which switching emphasis from app to immersion gives the biggest return
