Explanation of the user agent ‘iOS’ in web radio logs

What is the “iOS” user agent?

The UserAgent "iOS" appears in web radio logs when a user accesses your stream via an Apple device such as:

  • iPad
  • iPod Touch

iOS is Apple’s mobile operating system and is used by millions of people worldwide – especially for listening to music and radio on the go.

What does a typical iOS user agent look like?

An example of an iOS user agent:

  • the device (iPhone, iPad, etc.)
  • the iOS operating system
  • the browser used (e.g., Safari or in-app browser)

Apps such as myTuner, VRadio, and TuneIn on iOS devices also send such user agents—some with additional identification.

What does “iOS” mean in your logs?

If “iOS” appears in your web radio logs, you know:
