COVID-19 response by mobile apps in India
The possible benefits by which one can use mobile applications (apps) for contact tracking in managing the COVID-19 pandemic have been discovered. Various mobile apps have been developed and permitted by the Central and State Govt. and some medical organizations for controlling COVID-19. India has launched the Arogya setu app, the first of its kind in disease surveillance initiative used. This study provides a systematic review of mobile apps used in the COVID-19 pandemic and focuses on developing future e-healthcare services.
COVID-19 pandemic has spread to around 213 countries worldwide. Due to the lack of medical management for COVID-19 at present, the main focus on preventing spread by the public is by following physical distancing, hand hygiene practice and face mask to slow its spread.  The confirmed COVID-19 cases are advised home quarantine or hospital quarantine based on the severity of the infection with contact tracing. India reported its first COVID-19 case on 30 January 2020, with 257,192 confirmed cases and 7,207 deaths. Central Govt. imposed nationwide lockdown on 24 March 2020, followed by vigorous testing and contact tracing. 
Conventional systems used previously have not been designed to meet challenges like the one posed by the COVID-19 pandemic. [2, 3] Modern digital technology presents the possibility of improving health care efficiency in response to the epidemic. Such mobile health applications have been used previously during Ebola and Zika virus breakdown. Now is the time to update our digital surveillance system to help control the existing pandemic and avoid any such incidence in the near future. 
National Informatics Center, Government of India, developed and launched the Aarogya setu app to track COVID-19 in April 2020.  Various healthcare agencies in India have developed other apps to raise awareness, follow up of quarantined people, and enforce lockdown. [1, 3]
Aim of the study: To systematically identify and review mobile apps related to the COVID-19 pandemic in India.
Materials and Methods
The iOS and android app stores were searched with keywords like a pandemic, novel coronavirus, COVID-19. The search was done from the first week of December 2020 to the Last week of January 2021. The screening was based on app titles with their description. The gaming apps, apps on infections or disease not specific to COVID-19, and apps without English/ Hindi language were excluded.
Around 300 COVID-19 apps were included; 30 met the inclusion criteria. 270 apps were excluded as they didn’t focus on COVID-19 infections, few were gaming apps, and some without an English/ Hindi language interface.
Only free apps without in-app purchases were included. About 27 apps were for common public use, 2 for the quarantined foreigners, and one was for healthcare workers.
Out of the fourteen apps developed for quarantined people, one had a self-assessment tool, six had telephonic helplines, five had a function of questions and answers related to age, travel, underlying medical condition, and symptoms, and two had an electronic e pass facility available. Also, two apps had the function of confirmed cases with hot spot identification and contact tracing.
Central Government, together with the state government, is involved in developing these apps used in the country.  Many functions like contact tracing, quarantine, self-assessment were common at state-level apps. The information technology ministry has successfully installed the Aarogya setu app, which is available in 11 languages.  It is essential and has been made compulsory for people to download the app so that the contact tracing is done efficiently. Also, the state-specific app should be encouraged to help at the local level. With the rising cases, it is vital to install teleconsultation also in these apps.  Some apps did not have functions that could help health care workers, like tracking types of equipment and compile clinical data as used in other countries.  As these apps use Bluetooth connectivity, it can pose a risk for national security and user privacy. To counter this, Singapore has shared the app source code with the researchers for independent review.  Argentina is using apps that collect and record only the Bluetooth interaction.  To prevent that, the Indian government should address these concerns to the public and gather trust to set up these apps at a larger scale. 
This is an excellent step by the government of India for the COVID-19 m-health initiative. These apps are a source of providing disease-related information and knowledge at a larger level. 
For a country like India with a huge population and limited resources for testing, these apps will immensely aid in identifying the spots and individuals at risk at a faster level.
