When you look at iPhone space, you can see the amount of space occupied by your apps and data under Applications. This has app settings, downloads, media files, saved documents, and cached content. So, if you’re asking What Are Applications In iPhone Storage, it’s all the apps you’ve installed and what they store. Social media applications, games, music players, and streaming applications may occupy additional space over time. You will be able to control this through regular checks of storage and deletion of data when required.
