Learn languages with movies and TV series. SRT Flow is a subtitle viewer/player that helps you follow the dialogue, find unfamiliar words and save them for later study. The app displays SRT text offline according to its timestamps, while you watch the movie or series in your usual video player.

Add SRT files: the app does not provide or download movies or subtitles, play video or audio, or require an account. There is no automatic translation or dictionary. An AI agent (not included) with access to web search may help you find a suitable .srt file — specify the movie or series title, subtitle language and video version.

Import multiple files or a folder and organize them into groups — handy for TV series, with all episodes in one place. Parsed copies stay on your device. Deleting groups or files from the library leaves the originals untouched.

Fine-tune the speed from 0.250× to 3.000× with 0.001 precision. When different editions of a movie run at different rates, this adjustment helps match the subtitle timing to your version and reduce gradually increasing drift. This is a manual adjustment, not automatic synchronization with your video player. Save a speed for each group, or use the global default.

Navigate without interrupting your reading: scrolling through subtitles and searching do not stop the timer. Tapping a phrase jumps to its cue time and starts subtitle playback or keeps it running, rather than pausing it. While browsing, return to the current phrase with one tap. Each file remembers its position and reopens paused.

Search for words and fragments: a match counter, arrows and highlights help you find results. On the black screen, the current phrase is white and past phrases are gray. Future phrases are hidden during playback and visible when paused or browsing.

Save unfamiliar words with a link to their original phrase as you watch, without stopping the subtitle timer. Collect vocabulary without interrupting the movie, then return to it later and study the words in context. Depending on your chosen setting, a long press saves a word, copies a word or copies a phrase. You can delete saved words you no longer need.

The interface automatically uses English, Russian or Spanish according to your device language. The current release is free, with no ads or in-app purchases.
