Piperka is a web comic tracking and bookmarking service with over 5000 comics listed on it. It doesn't host any web comics by itself but maintains a list of them and an index of their archive pages.

Piperka Client uses Piperka's database to provide browsing and navigation for web comics' archives in a unified manner with an embedded browser. It stores user's bookmarks and periodically contacts the server to check for any updates to the comics that a user reads.

This program is geared towards mobile use.
