Extremely limited

Different conditions create subtitle sync issues. This app deals with one of them — if your subtitles are UNIFORMLY out of sync. One of the major causes of sync issues is frame rate differences between video and subtitle files. This app cannot correct those issues since the adjustment required is not as simple as just shifting everything backward or forward. So when the app's author refers to the "useless complexity of other apps," what he means is if you have a very simple issue, his app might be able to solve it. If you have a more complex issue, trust me, you will need one of those "other apps" with more robust features.

thank you for your constructive comment. Sorry to see that you were expecting more from SubShifter than an app to shift your subtitles. However, we believe that SubShifter handles very well the most frequent case - as you said - when subtitles are uniformly out of sync. And for the price of a cheap coffee.

Doesn’t work. Period.

The app doesn’t what it claims to. Import an .srt file, set the offset time, click “shift,” and…the timings don’t change. Worthless.

Hello, I would be happy to fix your issue. Could you send an email to with an example of the .SRT file having the issue? I could then update the software with the fix. Many thanks in advance!

Worked for me.

Worked on the first try. OS 10.13.5. Haven’t tested it enough to rate 5 stars.
