Hi all, I just wanted to update the translation status.

Thanks to several volunteers, the app is so far translated / being translated into:

• Spanish
• German
• French
• Polish
• Russian
• Portuguese
• Korean
• Dutch

I'd like to thank again all of them who are helping me translating it.

I'd like to remember you that any language is welcome. 

Japanese, Swedish and Italian might be the most used (and not yet translated) languages, though.

That'll be all for now!
