See what apps and data are taking up space in iOS, without iTunes? Is there a way i can see what apps and data are taking up space on my iPhone 8, running 12.4.1. 

I know if i plug my phone into iTunes i can get a report on this, but wondered if its possible without iTunes ?
To see what’s taking up all your storage space, open the Settings app, tap General, then tap [Device] Storage. 

There, you’ll get an overview of how much storage space you have used and how much you have available, and you’ll get a list of how much space each app uses for the app and associated data.
