Ask HN: Would you localize your app? Why? Have you done it already?

There have been some discussions on HN recently about how to localize an app. The comments have focused on (i) how to translate the strings in an app, (ii) how to optimise the title/description/keywords in the app store, (iii) why translation isn't enough.

If you have localized your app already:

- How did you decide it was worth doing?

- Apart from translating strings (in the app and on the store), what else did you do, to try to make your app successful in other languages/countries?

If you haven't localized your app:

- Why not?

- What could make you change your mind?
