The justtrack SDK can provide you with the advertiser id of the user if the user didn't limit ad tracking. Additionally, users are divided into three test groups (1, 2, and 3) based on their advertiser id. You can retrieve that test group id from the SDK, implement a different logic for one of the test groups, and then compare the (different) performance of that group on the justtrack dashboard.
