If you are developing mobile apps, you've probably already faced the challenge of managing language versions. We are developers ourselves and we also faced this problem.
That's why we have launched a very convenient service localize.io, which will help you cope with such problems as:
management of all language versions without involving a programmer;
quick changes without the necessity to submitt again the app in the Store;
convenient interaction between translators and product managers;
the possibility to place an order for translation directly from the service;
and much more.
