SubShifter will help you fix your subtitles. There are 2 main functions: Shift or Sync.
• Shift your subtitles files by adjusting the timing forward or backwards.
• Sync your subtitles whose shift is increasing through time (during the movie).

Quick and easy:

1. Choose your subtitles (pick from the Files app)
2a. Shift your subtitles (timing of your choice) or
2b. Sync your subtitles by entering the correct timing of 2 subtitles, and the rest of the subtitles will be automatically adjusted.
3. Save your shifted subtitles to the location of your choice (Files) or share anywhere.

The app works 100% OFFLINE. There is no server, no data collection and no ads.
Your privacy matters!
