We currently have multiple phases planned for language support.
When our app launches, it will have full support for French, German, Spanish (Latin American), Italian, Russian, and Korean. Following that, we're going to work on perfecting and releasing English, Dutch, Portuguese (Brazilian), Hebrew, Spanish (Castilian), and Arabic. When those are all finished, we will be adding Japanese and Mandarin. When these are all finished, we'll begin working hard on our community-sourced support for any language.
Quality is really important to us, which is why we don't have exact dates for these languages just yet. We want to make sure we've got them as polished as they can be before we release them on the app, but I promise: we're working as hard as we can to get them out as fast as possible.
