In the day of mobile devices, increasing your personal safety is easier
than ever before. What creates situations of danger for anyone traveling
alone is being cut off from other people that can help you. So, if you
have a mobile smartphone, then you can make sure that you are connected
with others at all time. Additionally, devices like smartphones and
tablets offer important tools that can further improve your personal
safety – like apps that make loud noises or very bright flashes of light
(or both).
