If you read manga online, here's an app that will update you once a new chapter is out.

So, we have created an extension to keep track of new chapters in all the Web pages that use the Madara- or MangaStream-Theme or are built using the Genkan Reader.

After you will install this extension and log in, you can read all your favorite manga and manga pages across multiple web pages and be informed when a new chapter is available.

You can also subscribe to the notification so you won't miss any news of your favorite mangaka.
