Helvetireader is a hosted user stylesheet for Google Reader served via a user-script. It aims to make the interface a clean, minimal experience where you’re not assaulted by an array of colours, social features and buttons.

It’s designed for people who just read the latest entries in expanded view without all the other gubbins. All you need is a browser that supports userscripts and, of course, Helvetica.

Pricing: FREE
Requirements: userscripts
