What is "iphone"

The iPhone is a smartphone developed by Apple Inc, released on June 29, 2007. iPhone, iPad, and iPod touch use iOS as their operating system (formerly known as iPhone OS). IOS native apps are written in or (since the release of iOS8) using the Cocoa Touch framework.

Most iPhone questions are also applicable to iPod touch devices.

In all cases the questions using this tag should talk about the device, so avoid using it to ask questions about App Store.

  • 3-Axis accelerometer
  • 3-Axis gyroscope
  • Magnetometer
