About this app

A movie on your device becomes the best English learning material.

One-Line Shadowing is an app that allows you to practice English shadowing using movie files (mkv, mp4, avi) and subtitle files (SRT, SMI) stored on your smartphone. Listen to the lines from your favorite scenes as many times as you like, repeat them, and record your pronunciation to compare it immediately.

**One-Line Shadowing** ■ Player Controlled via Subtitles

• Video at the top, full subtitle list at the bottom — scrolls automatically following the playback position

• Tap a line of subtitles to start playback immediately from that line

• Long-press a subtitle to select a section, and it will repeat infinitely with pauses before and after the line, as well as breathing time to repeat along

■ Pronunciation Recording

• Repeat the sentence you are currently repeating, record it, and compare it with native speaker pronunciation

• Recordings are deleted the moment the window is closed — they are not saved or transmitted anywhere

■ View Translation

• Long-press unfamiliar sentences to check them immediately via Google Translate (opens in an external browser)

■ Continue Learning

• Save sentences you want to practice again to favorites

• Remember playback position per video — continue from the last scene

■ No Privacy Concerns

• No sign-up or login required; all data is stored only on your device

• Videos, subtitles, and recordings are not transmitted externally

• Does not request storage permissions — accesses only files you have personally selected using the system file picker

Recommended for:

• Those who want to study English using American TV series or movies

• Those who want to memorize entire lines from their favorite scenes Minutes

• For those looking for a loop player for shadowing practice

※ Users must prepare the movie and subtitle files themselves. The app does not include the video.

※ This is a free app and displays banner ads. Ads are removed upon purchasing Premium.
Movies on your device become your English learning materials. Tap the subtitles to repeat a section, repeat after the speaker, and record yourself to check your pronunciation.
