There are many ways in which VideoSyncer helps you, here are the main ones.

Progress Tracking

Stop worrying what episode you were at

With VideoSyncer, whenever you are watching an online video in a series you added to VideoSyncer, it will automatically track the video time to the second. VideoSyncer also recognizes when you switch to a new episode and remembers the new url as the current episode.

You can, at any time and on any device, jump right back to the episode you left off. The episode will continue right where you left off. For example you're on your way home and are watching on the phone. You arrive at home and continue on your PC with the large screen, without having to search for the episode or fast-forwarding back to the right time.

Frequently asked questions by customers.

Does this work on ANY website?

Almost. There are two simple requirements a website must fulfill:

  1. There must be an HTML5 video tag (the norm nowadays, pretty much every site has this)
  2. Each episode must have a unique and identifiable url. '' is fine while '' is not.
Does the free version expire?

No. The free version lasts forever and will always be free.

What is a url pattern?

A url pattern is the pattern VideoSyncer searches for in the url of the websites you visit. As soon as a website matches a pattern, it is recognized as being an episode of the profile it matched with. For example you have the pattern '', that pattern will match when you visit '' and VideoSyncer will then activate on that website.

How do I know you're not secretly doing shady stuff?

VideoSyncer is open-source and you can verify the versions from the stores by building VideoSyncer yourself as described on GitHub.
