Aspects of the present disclosure involve systems, methods, devices, and the like for generating an unobtrusive and discrete barcode used for debugging. In one embodiment, a system is introduced that enables the tracking of application interactions on a user device. The tracking can include the generation of a debug id which can include a discrete string used to describe locations, preferences, and interactions with a user device application. The string may then be converted into a corresponding barcode which can be discretely displayed on the user interface of the application. In another embodiment, the barcode may be captured and/or retrieved for use in debugging the application, in an instance where an application malfunction is encountered.
