- CrawlFree is an application that helps blind people to find their lost objects around them.

- The application's major methodology of communication with blind ones is based on voice messages,
as the app starts with a voice message that tells the blind how to use the app.

- The blind asks the app to find an object, if this object is supported by the app,
the app guides the blind to move around slowly and the next phase of object detection and recognition starts searching for it using the camera,
with the movement of the mobile phone and on finding this object a vibration and a voice message releases to describe the current scene which informs the blind with the location of the desired object relative to another one,
and then gives the ability of searching for another object.

- If the desired object is not supported by the application, a voice message releases to inform the blind, and also gives the ability of searching for another object.
