Default language is set to Czech

[Eialidesse]

-When i launched the app first time, it was in czech language. Because i use my phone with french language but the app doesn't recognize it. So i figured out that the default language of the app is czech. You should replace it with english. And the app supports even norwegian but no french. That's weird.

-Also, i want to see my body mass index on the application. But this feature isn't supported by the app for now.
