Aarogya Setu, a mobile app developed by the ministry of electronics and IT to help citizens identify their risk of contracting Covid-19 (coronavirus). It is designed to keep an user aware of corona patients nearby him who has been tested positive or has any corona like symptoms. The tracking is done through a Bluetooth & location (recommend to keep this on all the time) , which can show our interaction with anyone who has tested positive or any corona patients passes by unknowingly. It has a tool for self- testing, in which it asks several questions to the user about their health and it comes across any health issues then it suggests appropriate measures to be taken. If any corona patient feeds his/her detail in this app then is also suggest the person for self- isolation and report it to the government. It also gives the updated cases on corona all across the India. Really, this is a very good app to be installed in this pandemic situation to keep ourselve, our family and as well as our nation safe from the harm of corona virus disease. I personally had installed this app and also suggested some of my relatives and friends to install this app and shared the link too.
