Built around how immersion actually works
Comprehensible input is the work. Submmersive is the quiet bookkeeping around it — so the only thing you have to think about is pressing play.
Log immersion in seconds
Capture every show, book, movie, podcast, or video you take in. Reuse your media library so logging a session is two taps.
Keep your streak alive
Set a daily minutes goal per language. Hit it and your streak grows. A live progress bar shows exactly how close you are today.
See your trends
Minutes per day, a rolling 7-day average, a breakdown by media type, and a streak heatmap — so progress you can't feel becomes progress you can see.
Track every language
Study more than one language? Add as many as you like, each with its own goal and library, and switch the active one whenever you sit down.
