Device Locale plugin is available in Enterprise and Community Editions. If you'd like to see it in action, you can sign-up for an Enterprise Edition trial or setup your own Community Edition instance.
This plugin lets you record and report on the device language of your application users. You can easily see top languages and segment all the data based on this information so that you'll have a clear idea which language to focus your localisation efforts on and also whether you need to do any optimisations for different languages.
