Noonlight

Noonlight (previously known as Safetrek) is an app that lets you contact the police in a flash, simply by tapping a button on your smartphone screen. As soon as you do, the police will be notified of your location and come as quickly as possible.

The way Noonlight works is easy: if you're afraid for any reason, or you're in a dangerous situation, all you have to do is press (and keep pressing) the blue button. As soon as you release your finger, the app notifies the authorities, who will then immediately come to your aid. If, on the contrary, the situation you're in is no longer dangerous, or you simply want to cancel the alert, all you have to do is enter your four-digit security code.

In order to create a Noonlight account, you'll need a phone number from the United States. Although there's a month-long free trial, the monthly subscription costs $2.99, which you can pay directly from the app itself. From the options menu, you can cancel your subscription at any time.

Noonlight is a very useful app for all kinds of people. With it, you can rest easy knowing that, in less than three seconds, the police will come help you as quickly as they can. And you can do it just by pressing a button, without having to make a call and without having to say or type a single word, either.
