A mobile device identifies whether potentially distracting applications are running on the mobile device as well as the activity of the user, via at least one sensor on the mobile device. If it is determined that at least one potentially distracting application is running and the user is engaged in an activity that may become dangerous due to use of the at least one potentially distracting application, a warning is provided on a user output of the mobile device when the mobile device is within a predetermined time and/or distance of an identified hazard.
