# How to target in-app experience based on the user's device language?

Whatfix enables you to target in-app experiences to users based on their device language. Create [User Segments](/mobile/docs/user-segment) to group users who share the same device language and target the in-app experience to them. The segments can be created by defining the **Device Language** [User Property](/mobile/docs/what-is-a-user-property).

Use the following steps to create a User Segment based on the device language:
