Piperka

Piperka.net is a webcomic-tracking site where you can place bookmarks for webcomics. It will keep you informed of when a given comic updates.

I found piperka to not be very suited for mobile use, so I made an app for it. It's unofficial, but Kaol has given me permission to distribute it, and it's ad-free per his request.

You can log in, view your list of updates, and get redirected to your current page via your phone's default browser. For this to work, you will also need to be logged in with your browser as well. Usage requires an account already on the site, which you can make for free.

For the moment, the app does exactly what I, personally, need it for. I'll be happy to respond to bug reports and feature request!
