Which languages should I translate into? (original) (raw)

The short answer is: it depends.

Things to consider

Country relevancy: if you're working on a food delivery app which covers cities in one country only, it makes sense to focus on that particular country and language. However, if your app isn't tied to any specific country or market, it may make sense to launch in as many languages as your budget allows.
If your app isn't available in English, consider English as one of the high priority languages to translate into. Even outside of English speaking countries, English literacy can be significant, especially in the smartphone user segment.
Popularity of the app category: various apps could be more popular in one country and less so in the other. With this interactive research tool you can dive into the activities of smartphone/tablet users by country.
Competition: similar to the popularity, the competition can also vary by country. Do a research in the app stores to get some idea.
Your budget: using the App Translation Service, translating a typical app and store description into one language may cost around USD50. Note that the translation price is calculated on a per-word basis, so your actual cost depends on the amount of text in your app and store description. Prices may also vary by language pairs and the vendor you select.
