Yes you can analyse the performance of the app running on production environment i.e. a user’s device.
The feature provide you a chance to enhance the experience of the users by knowing the issues in run-time environtiment. It helps you get the API(s) taking longer to respond and what not. Its in beta version but works like magic. It collects all the data and show the data in Firebase console.
