Translating your app for iOS, Android or Windows Phone will help you reach new potential customers.
Localizing an app can increase your sales exponentially. A word of warning, though: other features being equal, users are much more likely to download the best translated app, because a fluent translation is associated with greater reliability. Poor quality or machine translation will definitely discourage prospective purchasers.
Furthermore it should be borne in mind that the app needs to be fully translated (interface, descriptions in the store, documentation) and images and icons, where necessary, have to be adapted for use in the new country.
This is the reason why it is extremely important to choose a competent and qualified partner, with an extensive knowledge of the internationalization process. We are very familiar with the mobile apps development process, because we have not only translated hundreds of apps, but also created some of them on our own. Therefore we can best help you launch your multilingual app on international markets.
