Steel is a discontinued freeware web browser developed by Michael Kolb under the name kolbysoft. It is a fork of the default browser for Android, taking its WebKit-based layout engine and providing what is intended to be an easier and more "touch friendly" user interface. Steel was one of the first Android applications to support automatic rotation based on the hardware's accelerometer and a virtual keyboard. This feature is now more common among Android applications. In 2010 Skyfire purchased kolbysoft and the Steel browser.
