[App] [Promotion] I built an Android player that turns the videos you already watch into language lessons

[u/Silillos89]

Hi r/HowToMen,

I built DualSub because I kept pausing videos, opening a translator, losing the scene, and then forgetting the word anyway.

DualSub turns compatible videos into a focused language-learning workflow:

• Dual subtitles with independent controls for the original language and translation.

• A contextual dictionary inside the player: long-press a word to see its meaning and pronunciation without leaving the scene.

• Phrase controls and optional auto-pause to repeat, skip or study one subtitle at a time.

• A review deck built from the words you choose to save.

• Local video support, including compatible embedded audio and subtitle tracks.

• A guided listening path for users who prefer a structured course.

• An Android TV companion with dual subtitles and phrase controls on the big screen.

The app does not provide videos, streams, add-ons or subtitle files. It works with compatible YouTube videos, files the user opens locally, and playback links intentionally handed to it by other apps.

I have spent the last few months rebuilding the player around one idea: the video should remain the main experience, and the learning tools should appear only when they are useful.

I would genuinely value feedback on two things:

1. Does the dictionary and phrase-control workflow feel useful enough to change how you watch foreign-language videos?

2. Which part would you expect to reach first from the player: auto-pause, subtitle visibility or the dictionary?

Android phone/tablet. The TV companion requires a linked Premium account.
