Today we are happy to announce that the App Translation Service, previewed in May at Google I/O, is now available to all developers. Every day, more than 1.5 million new Android phones and tablets around the world are turned on for the first time. Each newly activated Android device is an opportunity for you as a developer to gain a new user, but frequently, that user speaks a different language from you.

To help developers reach users in other languages, we launched the App Translation Service, which allows developers to purchase professional app translations through the Google Play Developer Console. This is part of a toolbox of localization features you can (and should!) take advantage of as you distribute your app around the world through Google Play.

We were happy to see that many developers expressed interest in the App Translation Service pilot program, and it has been well received by those who have participated so far, with many repeat customers.

Here are several examples from developers who participated in the App Translation Service pilot program: the developers of Zombie Ragdoll used this tool to launch their new game simultaneously in 20 languages in August 2013. When they combined app translation with local marketing campaigns, they found that 80% of their installs came from non-English-language users. Dating app SayHi Chat expanded into 13 additional languages using the App Translation Service. They saw 120% install growth in localized markets and improved user reviews of the professionally translated UI. The developer of card game G4A Indian Rummy found that the App Translation Service was easier to use than their previous translation methods, and saw a 300% increase with user engagement in localized apps. You can read more about these developers’ experiences with the App Translation Service in Developer Stories: Localization in Google Play.

To use the App Translation Service, you’ll want to first read the localization checklist. You’ll need to get your APK ready for translation, and select the languages to target for translation. If you’re unsure about which languages to select, Google Play can help you identify opportunities. First, review the Statistics section in the Developer Console to see where your app has users already. Does your app have a lot of installs in a certain country where you haven’t localized to their language? Are apps like yours popular in a country where your app isn’t available yet? Next, go to the Optimization Tips section in the Developer Console to make sure your APK, store listing, and graphics are consistently translated.

You’ll find the App Translation Service in the Developer Console at the bottom of the APK section — you can start a new translation or manage an existing translation here. You’ll be able to upload your app’s file of string resources, select the languages you want to translate into, select a professional translation vendor, and place your order. Pro tip: you can put your store listing text into the file you upload to the App Translation Service. You’ll be able to communicate with your translator to be sure you get a great result, and download your translated string files. After you do some localization testing, you’ll be ready to publish your newly translated app update on Google Play — with localized store listing text and graphics. Be sure to check back to see the results on your user base, and track the results of marketing campaigns in your new languages using Google Analytics integration.
