Promoting a mobile app or game only in one language is not enough. Actually, an app publisher should create multiple localizations in order to cover the top grossing and emerging geographical markets. We recommend considering no fewer than 10 languages for mobile app localization.
App Store Superpowers are the countries holding leadership in terms of downloads and revenue. The latest stats show that the United States is not the front-runner anymore. In 2014, Japan and South Korea surpassed the United States by revenue on Google Play. At the same time, Japan is hot on the United States’ tail on the App Store, where it is #2 by revenue.
According to App Annie’s infographic presented at GMIC Silicon Valley event in December 2014, the following three countries form the App Store Superpowers: Japan, South Korea and the United States.

When building the list of the top 10 languages for mobile app localization, we should keep in mind other English speaking countries like the United Kingdom, Canada and Australia, where mobile apps and games gain high revenue as well. Collectively, the English speaking world is still dominating on the mobile app market.
Another significant player on both iOS and Android is China, which became the top 2nd gaming market by revenue worldwide in 2014. Bear in mind that games drive up to 75% of total revenue on the App Store and nearly all revenue growth on Google Play. App Annie Index Market Q3 2014 report puts China to #3 by revenue on the Apple’s App Store. The only reason why this country has not reached similar revenue rank on Google Play is that it got numerous Android app stores, and only 13% of Android market share in China belongs to Google Play.
As a matter of a fact, simplified Chinese, which is common for Internet and mobile users in China, goes to the #4 in our list of top ten languages for mobile app localization, following English, Japanese and Korean.
Let’s not forget about the Old World. Traditionally, the lion’s share of revenue generated by mobile apps and games in Continental Europe belongs to its most developed countries: Germany, France and Italy. It is worth noting that the estimated revenue from mobile games in Western Europe, according to AppLift and Newzoo, reached $3.2 billion at the end of the year 2014. Which makes Western Europe the third region in the world by revenue from mobile games, after North America and Asia Pacific.
Germany is the leading European market by revenue from mobile apps and games. In App Annie Index: Market Q3 2014 Germany was reported the #4 country by revenue on Google Play. in our list of the top 10 languages for mobile app localization, German language wins #5, and #6 goes to French. Italian (#9) follows Portuguese and Spanish which take #7 and #8 respectively. The reason why Portuguese ranks better than Italian and Spanish is that Brazil’s market share of Google Play downloads increased more than any other country worldwide in Q3 2014. In total, estimated year over year revenue growth in Latin America’s mobile gaming segment exceeds 60%, which is bigger than elsewhere.
In the end, we recommend looking at another huge emerging market, the Southeast Asia. As stated by Newzoo in 2014 Global Games Market Report, the following six countries represent 97% of game revenue in Southeast Asia: Indonesia, Singapore, Malaysia, Thailand, Phillippines and Vietnam. So, Malay becomes our #10 language for mobile app localization, which is the most widely spoken in this region.
Let’s summarize, here’s our top 10 mobile app localization languages for 2015:
