App localization is made incredibly easy on the iOS and Android stores, allowing any developer to sell their application internationally. The development kits help with app localization for different languages and regions, and a localized app is much more appealing to regional users. But which languages should you pick?
App Localization for iOS
iOS officially supports dozens of languages, so app localization into all of them is beyond the budgets of most developers. Fortunately, both app stores provide download statistics that you can use to make this choice easier.
The iTunes Connect console provides download statistics by region and country, rather than languages.
Log in to iTunes Connect, and select “Sales and Trends”
Select an appropriate date range, and click sort “By Territory”
You’ll see a list of downloads by region. This is a little broad- select a region to drill down to the specific countries.
You’ll see a list of downloads by country. Apple does not provide usage history by language, but an app performing well in Germany may warrant a German translation.
App Localization for Android
Select your app from the list in the Google Play Developer Console
The Developer Console provides breakdown of your users by language and region. This is great information for deciding which languages to pick for android localization.
The Developer Console also provides a list of popular languages in your category. From this list, Japanese, Korean, and German would be good languages to pick for a Health and Fitness application.
By taking advantage of the Google Play Developer Console and iTunes Connect, you can determine the regions where your app is gaining the most traction. From there, you can focus your app localization efforts for these top languages, saving money while still reaping the benefits of a larger target market.
