Load a subtitle file, then press play the moment the movie starts on your TV. Nudge the sync if it drifts.
1. Load an .srt or .vtt subtitle file. 2. Press Play the moment the movie starts on your TV. 3. Tap the subtitle area to play or pause. 4. Jump 10s with the rewind/forward buttons, or drag the scrubber to seek anywhere. 5. If the subtitles drift out of sync, nudge them with the -0.5 / +0.5 buttons; reset sets the offset back to zero. 6. The screen stays awake while playing, and the fullscreen button hides everything else. Everything runs in your browser. Nothing is uploaded anywhere.
