Localization – use some user friendly service

I'd really like to see the app in my native language (Czech) and would gladly help with translation, but unfortunately I'm not familiar with Android development and pull requests that much. And I think I'm not alone, so I'd lik 561A e to ask if it would be possible to use some user friendly localization service instead? One of them is crowdin.com – it's free and allows export in different formats.
