Gem for Yandex.Metrika
I have just published Gem to work with Yandex.Metrika API. Yandex.Metrika is a web-analytics tool from Yandex (similar to Google Analytics). With Metrika gem you can authorize with OAuth protocol, work with counters, goals, filters, operations and grants. And of course you can fetch every statistics that is available for your site.
