Install Referrer is a utility application designed for Android platforms, primarily focusing on testing the referrer attribute during app installations. This tool allows developers to verify the referrer data sent by the Google Play Store upon the initial launch of their applications. It provides specific links for testing, including Play Store URLs, market URL schemes, and Chrome intents, all of which facilitate the testing process by incorporating a customizable referrer value.

Although the application is marked as deprecated and encourages users to transition to the Play Referrer API, it still serves as a useful resource for understanding how referrer attributes function. The application is available for free, making it accessible for developers seeking to enhance their app installation processes. For further insights, a GitHub project offers additional information and resources related to this tool.
