I was wondering, how do you put up a translated version on the market for your app (both Android and iPhone)? Do you have to make a separate app for each language or is there a way to put multiple languages in the same app so that if they are in a country that speaks Spanish for example it would download that version?
Also has anyone tried translating their popular apps? Was it worth it on sales?
There might not be an immediate benefit to having multiple localized versions of your applications but it feels inevitable that localized applications will have more earning potential. (I've heard rumors that China's iPhone market may outsell the US iPhone market this year. Ignore the other six billion people on Earth if you wish...)
In practice, you provide a single application with multiple localizations baked right in. Details on how you internationalize your application varies from platform to platform, so I suggest reading the Apple internationalization guidelines or the Android internationalization guidelines.
