The iPod Touch (stylized and marketed as iPod touch) is a brand of iOS-based all-purpose mobile devices designed and marketed by Apple Inc. with a touchscreen-controlled user interface. It connects to the Internet only through Wi-Fi base stations, does not use cellular network data, and is therefore not a smartphone. Similarly to an iPhone, it can be used as a music player, digital camera, web browser, note-logger, and handheld gaming device.[6] As of May 2013, 100 million iPod Touch units had been sold since 2007.[1]iPod Touch models are sold by storage space and color, with all models of the same generation typically offering otherwise identical features, processors, performance, and available operating system upgrades. An exception was the fifth generation, in which the low-end (16 GB)[7] model was initially sold without a rear-facing camera.[8] The current iPod touch is the seventh-generation model, released on May 28, 2019.The iPod Touch is currently the only product in Apple's iPod product line, following the discontinuation of the iPod Nano and iPod Shuffle on July 27, 2017. Following the discontinuation, Apple revised the storage and pricing for the iPod Touch with 32 and 128 GB of storage
