HOW MANY GIGABYTES ON IHEART RADIO APP?

The iHeartRadio app itself doesn't take up a specific amount of storage in terms of gigabytes, as it primarily streams content rather than storing it. However, the app's size can vary depending on the device and updates, typically ranging from about 100 to 200 MB. Streaming music and radio through the app consumes data, which can vary based on the quality settings and duration of use.
