Abstract: A device implementing a system for in-application messaging includes a processor configured to, receive, from a server, a message and a rule, the rule specifying a condition to be satisfied prior to displaying the message in association with an application, the condition corresponding to user interaction with respect to the application. The at least one processor is further configured to store the message in local memory, and determine that user activity performed with respect to the application satisfies the condition corresponding to the user interaction. The at least one processor is further configured to, in response to the determining, retrieve the message from the local memory, and display the message in association with the application.
