We recently released a version of the Loss of the Night app that works in Arabic, Catalan, Chinese, English, French, German, Italian, Japanese, Polish, Romanian, and Spanish.
It may become possible for us to do another extended language release sometime in 2014. If you would like to volunteer to translate the app into another language, please send me an email. Most of our translators needed about a half day to do the job.
We currently have volunteers for Czech, Korean, (Brazilian) Portuguese, and Slovak.
