Research: Smartphone apps assist in monitoring and reporting COVID-19

The widespread use of assorted smartphone apps launched through the COVID-19 pandemic, most notably contact-tracing purposes, will be seen as a constructive growth.Nonetheless, extra analysis have to be carried out to find out how these applied sciences will be refined for future use instances.

This was the important thing conclusion of a review paper revealed in Nature Biotechnology, whose authors mentioned that, regardless of affected person privateness and information safety considerations, the apps have been useful to contact tracing, particular person screening and a common understanding of outbreak epidemiology.

“Whereas there have been successes and failures in every class, outbreak epidemiology and particular person screening have been considerably enhanced by the attain of smartphone apps and accent wearables,” the report famous.

The primary benefits of smartphone-based app information embrace close to real-time outcomes, and the flexibility to extrapolate information from massive inhabitants teams. Functions that had been developed to trace influenza, earlier to the pandemic, have been in a position to pivot to monitoring COVID-19.

The usage of apps to diagnose potential COVID-19 signs is also improved sooner or later as smartphone cameras grow to be extra subtle. A perfect diagnostic app ought to combine options discovered throughout a large number of apps at the moment available on the market. 

“To be accessible to an underrepresented and underserved inhabitants, it ought to be capable to combine the data from any sensor, together with that from much less subtle cell gadgets with restricted options,” the report mentioned.

Contact tracing, essentially the most generally used COVID-19-related smartphone app perform, was cited by the paper as having essentially the most critical information privateness points. Authors of the report consider that future contract-tracing apps ought to take into account not solely proximity, however native biometric, pathogen and environmental information to enhance efficacy.

“The best contact-tracing app would work in actual time, protect information privateness, adjust to native rules, result in actionable and measurable outcomes, be on native gadgets to keep away from bandwidth points and, for public well being functions, not require opting in,” the report beneficial.


With greater than six billion smartphones in use worldwide, the flexibility of cell apps to help in info gathering and dissemination will probably be vital going ahead. Smartphones are already used to collect geolocation information and different varieties of information accrued by customers.

Because the paper famous, nevertheless, the important thing points to be resolved give attention to information safety and privateness points, in addition to on the challenges of digital well being illiteracy and structural inequities.

There are additionally indicators that smartphone apps might be geared up with extra superior diagnostic performance. A smartphone-based COVID-19-detection check from Australia showed a high degree of accuracy, appropriately discovering COVID-19 in 92% of contaminated individuals of a scientific trial.

As well as, researchers found {that a} loop-mediated isothermal amplification-based methodology mixed with smartphone detection was in a position to check for COVID-19.


The usage of cell apps might have further preventive makes use of for at-risk populations throughout pandemics or seasonal well being occasions.

In August 2021, U.Okay. home-care supplier Cera launched a flu-tracking and therapy app, which makes use of synthetic intelligence and machine studying to assist earlier prognosis and quicker therapy of flu in older inhabitants teams.

“Continued use of apps throughout the digital infrastructure guarantees to supply an vital instrument for rigorous investigation of outcomes each within the ongoing outbreak and in future epidemics,” the Nature Biotechnology report famous.
