Fabric

Now that you have your app you want to make sure that as many people as possible are using it. The trouble is that when you have many people using your app, and some of them are reporting crashes, there is no way to figure out how many are actually affected.
 
Fabric aims to take care of this issue by providing its users with real-time alerts, and all the information that you need is provided, and that includes full stack traces and a good insight on who’s affected.
 
With the help of Fabric, users have quick access to all the right metrics and that you remain crash-free.
