I did for android app. we simply looked at number of installations by country and we had a lot of people asking for their language to be supported. we used google services to do the localization. for us, main thing was simply making all labels, etc make sense for native speakers of the two other languages (beside english) that we added

Thanks. Does your app have any server-side content (apart from user-generated content)?

No, all of the content is user-generated. For this content, we just display it in the language it was submitted. The localization I was talking about is more for static things like buttons and general navigation around app.
