Top 5 Contact Tracing Apps You Need for Fighting Against COVID-19 in 2023

We all know how the COVID-19 pandemic has hit most of the world’s population since it started. Still medical and civil workers from different parts of the world are putting their greatest efforts to fight against coronavirus. Supporting them, developers of Google and Apple are drawing up contact tracing tools and helping in fighting against this pandemic outbreak. Not only them but recently, most developers have taken the initiative of developing the contact tracing system in the form of a tool. Today, we will see what is contact tracing and how helpful the contact tracing technology is.

This blog also gives you information about best contact tracing apps introduced by several nations and helps recognize COVID-19 positive victims, voluntarily.

Contact Tracing App – Why is it needed?

To know if someone has turned out a positive victim to COVID-19, first you should know the victims. Contact tracing apps help you identify and self-report who are experiencing COVID-19 symptoms and report it to concerned health authorities immediately through the app. As the app traces the victim’s health along with the closest contact they have met recently, it becomes easy for medical health associations to test and confirm whether positive or negative.

We will see the benefits of a contact tracing app and different types of contact tracing apps available and to make use of. To our known knowledge, Google and Apple collaborated and introduced a contact tracing app that functions with the Bluetooth option without using the user’s GPS location. Likewise, many software companies have come forward to introduce such apps and help society to become free from this pandemic.

Let us take a look at how a contact tracing app works, and how it benefits the public and medical health associations.

Contact Tracing App – How It Works?

With contact tracing apps, medical health officials can automatically trace people who might have come in close contact with infected people. This is the way how these apps work in real-time, but users should keep the Bluetooth option and GPS turned on for most of the contact tracing apps introduced.

  • Turn on the Bluetooth option on your mobile and enable GPS for the app to identify your location.
  • After you install a contact tracing app, it calculates the distance between your phone and others’ phones within reach and has the app installed.
  • Now the app saves the key logs of GPS location data and others who have come in contact with each other, for the day.
  • These details are stored anonymously and so, none of your contacts get to know who has been infected or any other sensitive and confidential information.
  • When someone experiences COVID-19 symptoms or tested positive, they should inform it in the app.
  • Now, the app will send an alert to those other users, who came in close contact with the victim frequently, without revealing the identity.
  • Later, users who have received alerts about the affected person will receive notifications on how to take it further from the current situation.
  • Also, many apps show the nearby healthcare facilities for COVID-19 testing and necessary precautions one should follow to handle such terrific conditions.

How contact tracing apps ensure privacy protection?

While installing any app, data privacy and protection becomes the primary concern of every user, and of course, their fear is correct. Especially, when it comes to installing a contact tracing app, users may have concerns about whether their health-related data will be shared with others, or what if a third-party accesses their data.

This is where the government comes into the picture. Every nation set their own restrictions and norms towards not sharing their app information and public health information with any other nation. They keep data anonymous from others, which are technically called data localization.
