Best Contact Tracing Apps For COVID-19 Pandemic in 2020

best-contact-tracing-apps

Turns out, not just medical and civil workers are contributing to the fight against the COVID-19 pandemic.  Software developers from Apple and Google are crafting technical tools to help combat the virus and save lives. How are they doing it?  By developing APIs or Application Programming Interface.  Not just Apple and Google, many developers around the world are working toward the same goal- a healthier world.  Health departments of many nations have developed contact-tracing apps for their citizens.  In this blog, you will read about what is these apps do and which are the best contact tracing apps developed by different nations.

Introduction

It is a new world, a new era.

COVID-19 pandemic has changed the world we used to live in. We go out only if it is really necessary.  Every time we need to go out of the house, we return to the house worrying about contracting the Coronavirus.  What if we had unknowingly come in contact if some infected people?  This fear is reasonable and natural.

Moreover, almost every nation is going through a similar experience.  They are making every possible attempt to slow down the spread of the virus, from announcing lockdowns to taking the help of technology.  The Public Health Authorities of many countries have collaborated with mobile app developers to develop contact tracing apps.

Google And Apple Collaboration

Google and Apple have collaborated to develop contact tracing API which is now called exposure notification API.  They released the first version to select app developers associated with public health authorities (PHAs) around the world.

These apps help the authorities as well as the citizens to keep their health in check.  If Google and Apple are doing something together, it must be important, don’t you think? Let’s see what these apps do and how they work.

What Is Contact Tracing?

Even with people following social distancing, the chances of contracting the virus are still there.  As we see on the news and social media, more and more coronavirus cases are added each day.

According to the CDC, in manual contact tracing, public health staff work with a patient to help them recall everyone with whom they have had close contact during the timeframe while they may have been infectiousManually carrying out such a task for a disease like COVID-19 is not plausible.

This is the reason most Governments have devised contact-tracing apps to make the procedure less cumbersome and rapid.

How Do Contact Tracing Apps Work?

Contact tracing apps automate the laborious manual process of tracing back people who might have come in contact with an infected person.  This is how they work:

  • The app uses Bluetooth® Low Energy and GPS navigation.
  • Once someone installs the app, it will start logging the distance between the phone and other phones nearby that also have the app installed.
  • The app stores the log of GPS location data and other people that have come in contact with each other. This log is anonymous to maintain privacy.
  • If someone tests positive or has symptoms of COVID-19, they need to inform it in the app.
  • This will trigger an anonymous alert to those other app users with whom this person came into significant contact over the previous few days.

Privacy Protections

Whenever someone installs such apps, they have a genuine fear of losing their privacy.  Doubts about getting data leaked or stolen by a third party are reasonable privacy concerns.  This where the role of a government comes in.

Each nation develops its own app without sharing any of its Public Health information with any other country.  The database is also kept anonymous for safety.  This is known as ‘Data Localization’.

Here is a video that will tell you what digital contact tracing is and why security is important.

Let’s now check out a few of the best contact-tracing apps developed by various nations.

FAQs

Are contact-tracing apps safe?

There are a lot of doubts and concerns about data safety that people are raising.  Many government agencies have made sure that the app doesn’t require any other information other than location and Bluetooth access.  However, in order to safeguard your data while using the app, you must check the permissions required by the app.  You must give only the required permissions that are needed to run the tool properly and nothing else.

Which technology is used in these apps?

These smartphone apps use two main technologies- Bluetooth® and GPS navigation.

Bluetooth®  is used to detect the number of people each person has come in contact with.  The stronger the Bluetooth signal, the lesser the distance between two people.

GPS navigation is used to detect the location of smartphone users who have the app installed.

What have Google and Apple proposed?

Tech companies Google and Apple have proposed a joint effort to develop an API using Bluetooth technology to help governments, human contact tracers, and health officials reduce the spread of the virus, with user privacy and security central to the design.

Conclusion

We hope that now your concept about contact tracing apps is clear.  These were just a few applications and we will keep adding more to the list.  The major technologies, that these apps use, are GPS navigation and Bluetooth®.

Being an Android and iPhone app development company, we have our fair share of projects using these technologies in our projects. In fact, we have developed a range of applications that use this technology.

Walkonomics was featured in The Guardian as the ‘Best iPhone App of the Week,’ which is an app for finding a route, surrounded by greenery and parks.  On the other hand, Trackster is a real-time phone tracking application. It lets users track their kids, friends, or employees as the need be.
