Where do you translate or localize your apps?

Hi,

I have some ios and android apps and i am translating them into the principal languages.
It is working for me, because in the apps i have translated, i have more downloads and incomes, so i think i am in the righ way.

The problem is finding the best translation services, because some of them are really expensive.

This is my experiencie:
- ICanLocalize.com: The service is very expensive and they are not fast in the translations.
- OneHourTranslation.com: They are fast, but they are not specialized in localizing apps, so sometimes, they dont know how to translate some strings files correctly.
- OnTranslate.com. This is the last service i have tried i at this moment, it is the best one i have tried because i have not seem this price in other professional translation services.

I hope other developers can share their experience.

Thank you!
