1. Introduction

Since the outbreak of the coronavirus in December 2019, the cases of COVID-19 in the world have been increasing rapidly. By August 21, 2020, over 226 million cases had been confirmed in the world, with more than 7.9 million deaths. Nonetheless, the recovery rates differ drastically in various countries due to different factors such as health interventions, effective planning, and outbreak management approaches [1, 2].

Due to the limitations of face-to-face clinical consultations, the healthcare systems face some challenges in delivering patient care. This experience underscored the inability of traditional methods alone to effectively manage the disease, highlighting the need for innovative solutions. In response, new information technologies, such as telemedicine and smartphones, were swiftly developed to enable optimal control of the virus [3]. The ability of society and hospitals to effectively manage and respond to widespread outbreaks of pandemics like COVID-19 can be enhanced. They could update technologies, which help governments identify, track, monitor, and treat patients with COVID-19 and manage human resources, economic resources, and time [47].

One of the key applications for coping with COVID-19 is the use of mHealth [8]. The World Health Organization’s Global Observatory defines “mobile health (mHealth) as a public health practice supported by mobile devices such as mobile phones, patient monitoring devices, personal digital assistants, and other wireless devices” [9].

Nowadays, mHealth is used by all age groups, such as mother-child groups and older people [10, 11]. Populations in low- to middle-income areas benefit from mHealth applications through the provision of effective healthcare services, and governments that implement mHealth developed in low-income areas indirectly promote equity in access to healthcare services by bridging gaps in limited resources [12, 13].

Studies have revealed that mHealth educational applications and games have increased during quarantines [1416]. Given the expansion of online systems, particularly in advanced countries, the intelligent use of existing data to identify future trends and current events or to identify comprehensive risks is considered a common and logical issue. When technologies focus on health, they provide tools that help communicate, structure, and organize data and information [17].

During COVID-19, emerging mobile applications could become a useful tool to help individuals with self-care, information, and crisis management and be a resource for health professionals to use [18]. Evidence indicates that mHealth has been used to empower healthcare providers to reach vulnerable people, conduct monitoring, and provide treatment, health-related education, and counseling [1922]. Particularly, in the rapidly evolving environment of COVID-19, mHealth applications have hada key role in reducing cases of COVID-19 [3]. Additionally, mHealth applications are extensively used for various purposes to reduce the COVID-19 pandemic, such as self-assessment, contact tracing, information dissemination, minimizing exposure to the disease, reducing face-to-face visits, controlling disease symptoms, and facilitating access to healthcare [9, 23].

Echeverría et al.’s results on remote health monitoring in the workplace for early detection of COVID-19 cases using a mobile health app showed that the COVIDApp helps in early detection and rapid activation of protocols in the workplace, thus limiting the risk of spreading the virus and reducing the economic effect of COVID-19 on the manufacturing sector. The platform indicates the progress of the infection in real time and could assist in the design of new strategies [24]. Furthermore, a review study associated with the monitoring of symptoms of COVID-19 using mobile health applications indicated that the mHealth applications designed to monitor the symptoms of COVID-19 were of high quality and suggested that the program developers should follow the updated technical and clinical guidelines of the Centers for Disease Control and the World Health Organization (WHO) to better monitor the symptoms of COVID-19 [25]. Islam et al.’s results for exploratory analysis of mobile health applications developed for COVID-19 revealed that the key design features of mobile health applications are reliability, performance, usefulness, support, security, privacy, flexibility, responsiveness, ease of use, and cultural sensitivity [26].

However, there have been some studies about using mobile applications in health management. Initial reviews by the authors indicated that no systematic reviews have been done so far focusing on the capabilities, key functions, and challenges faced by mHealth programs in health management in the era of COVID-19. Therefore, given the capabilities that mobile health applications have in enhancing the process of self-care, communication, and crisis management and, on the other hand, identifying the features, advantages, and disadvantages of mobile health applications that developers can use in designing and developing them as best as possible, the study was conducted to review the developed mobile apps for health management in the COVID-19 era to identify the advantages, disadvantages, and the technologies used in these programs.

4. Discussion

Quarantine during the COVID-19 pandemic significantly impacted people with respiratory diseases, because they faced challenges in accessing health services as easily as before [42]. Moreover, restrictions imposed by governments and advice to stay at home caused interventions and other healthcare services to be transferred to the online environment or various mobile platforms. This has created a significant opportunity for the effective use of mobile health applications during COVID-19. Moreover, mHealth applications in the era of COVID-19 are expanding due to their very important role in control, diagnosis, remote monitoring of disease symptoms, patient education, self-management of the disease, sharing data with healthcare professionals, and reducing hospital burden [4345].

The study findings indicated that most of the apps designed with the general goal of helping to prevent the spread of the virus such as the use of masks, compliance with hygiene measures, and social distancing have been implemented. These findings are in line with other related studies [44].

According to the results, some of the most important technologies used in these applications included short messaging, telephonic and web-based programs, video chat, Bluetooth, and virtual reality and warning systems, in line with the findings of this study. Bluetooth technologies are used more often due to their low amounts of energy consumption and their effectiveness for contact tracing and mHealth applications [46].

It is suggested to use innovative technologies such as artificial intelligence (AI), machine learning (ML), and deep learning (DL) to enhance various approaches associated with the management of COVID-19, as AI, ML, and DL could prove effective in improving various approaches such as treatment, medication, screening, prognostication, contact tracing, and drug/vaccine development associated with healthcare services and management of COVID-19 [47, 48].

Considering the prevalent use of smartphones in society, one can leverage this technology to effectively manage similar situations. Hence, it is recommended to use the successful experiences in similar situations in the future.

Other results revealed that the applications designed for health management in the COVID-19 era have various advantages, such as identification of contaminated places based on barcodes, self-reporting of risk factors, sending reminders, early identification and isolation of people, examination of disease symptoms, observing health information according to the patient’s health records, and providing self-assessment and disease warnings to their users. According to the results of the study, other studies include capabilities such as vehicle movement permits, providing prevention instructions, viewing the results of COVID-19 tests, supporting contact with the treatment staff, identifying health facilities and health in the surrounding areas, reporting suspicious cases, and booking clinic appointments and testing for COVID-19 [14].

According to Schmeelk et al.’s research, mHealth applications for monitoring the symptoms of COVID-19 are guiding users, the ability to communicate between patients and healthcare providers, and gathering demographic information of users such as age, name, date of birth, ethnicity, and geographic location. Moreover, the research findings indicated that the US is at the forefront of developing top-notch mHealth applications for monitoring COVID-19 symptoms. Notably, state-specific programs had the most updated and detailed information, likely due to collaborative efforts between local, county, or state health departments. These special state apps listed the most common symptoms and provided information on the number of local cases of COVID-19 and research advances. The strengths of the US mHealth apps were the long-term storage of symptom assessments, high-quality aesthetics, comprehensive symptom lists, and evidence-based information aligned with the Centers for Disease Control and Prevention (CDC) [25].

Furthermore, the results of Alanzi’s review revealed that the features and functions of mHealth apps in the COVID-19 era are classified into seven categories: app overview (price, ratings, Android, iOS, developer/owner, country, and status), health tools (user status-risk assessment, self-assessment, E-pass integration, test result reporting, online consultation, and contact tracing), learning options (personalized notes, educational resources, and COVID-19 information), communication tools (query resolution, appointments, social network, and notifications), app design (data visualization, program plan), networking tools (location mapping-GPS, connectivity with other devices), and safety and security options (alerts, data protection). The study suggested that an integrated mHealth app with most of the features and capabilities analyzed in the study be designed and developed for managing COVID-19 [49].

Reviewing studies, data from professional organizations’ websites, and standards governing software development for health or medical devices are advised to overcome barriers to mobile health apps. Nonadherence to treatment was reported as one of the disadvantages of health management applications in the era of COVID-19 in the present study. It is necessary to pay attention to adherence to treatment and health guidelines in the design of these applications, as the cornerstone of the management of the disease is prevention with the help of adherence to health protocols [50, 51]. Overall, many factors have a role in improving patients’ adherence and satisfaction with the use of health information technologies.

In studies reporting positive outcomes, various factors have been considered in adherence. These include the utilization of user-friendly tools and equipment and the incorporation of usability in the design and development of telemedicine services, making services attractive to patients and motivating them. All of these factors contribute to an enhanced level of adherence. The provision of self-care equipment and services, without considering their design and usage, is inadequate for ensuring adherence. Furthermore, effective patient and healthcare provider interaction is crucial for the success of telehealth interventions [52].

Healthcare professionals have a key role in assisting patients in enhancing their self-management abilities and adherence. If healthcare providers lack a positive attitude towards interventions delivered via mHealth technologies, it may create uncertainty among patients regarding the use of these technologies, consequently leading to nonadherence to the prescribed treatment plan [53]. Furthermore, the consistency of treatment programs and easy and timely access to appropriate specialists are effective factors in increasing adherence [54].

The study results revealed that one of the limitations of using health management apps during COVID-19 was the preservation of patient information and confidentiality. Although mHealth apps offer many advantages, they also present substantial security and privacy challenges that may lead to data breaches, carrying potential social, legal, and financial ramifications [55, 56].

Some apps designed for the management of COVID-19, such as TraceTogether [57], Immuni [58], COVID Watch [57, 59], and PathCheck [58, 60], update their privacy policies so that no personal information that can divulge individuals’ identity is not collected. These apps use also clear policies on data usage and destruction.

It is suggested that people’s privacy should be considered when developing apps for public health and facing crises such as COVID-19. Thus, measures such as the following should be taken: placing the app on secure platforms, providing continuous updates for the app, requesting strong passwords from the users, authenticating users, and assuring users of their privacy during registration.

Given the wide use of COVID-19 management apps, despite the limitations of some apps, it is possible to help policymakers in deciding how to respond to COVID-19 and perform the necessary programs in this regard. Legal challenges, such as users’ privacy, are critical issues that must be considered when developing health information systems [61, 62]. The utilization of cutting-edge digital technologies, including the incorporation of applications for managing infectious diseases, proves highly effective as a potent tool in disease control and prevention efforts [63].

5. Limitations

One limitation of the study is the inability to access certain applications as they are published in languages other than English. In the fast-paced realm of COVID-19 studies, where different communities have diverse needs, quick research has been conducted, potentially impacting the quality of studies and software products in this field. Nonetheless, the researchers attempted to select studies that have the required quality by applying rigorous inclusion and exclusion criteria.

6. Conclusion

A comprehensive study of mHealth apps associated with COVID-19 could help app developers understand the shortcomings of current apps and contribute to the more successful development of future apps by integrating various capabilities, functions, and innovative technologies. Physicians could review different apps and recommend the most effective one to patients so that they can take better control of their health and adopt strategies to mitigate COVID-19 by increasing awareness through mHealth apps.

The results indicated that mobile apps have proven effective in controlling COVID-19 by identifying contaminated environments, identifying and monitoring infected people, controlling social distancing, and maintaining quarantine. The user-friendly design and usability of the app, as well as the existence of privacy laws, are necessary conditions for the development of mHealth applications. It is suggested that interests and concerns, ethical and security considerations, protection of personal information, and privacy of users are taken into account. Actions such as paying attention to usability in the design and development processes of the app, placing the app on secure platforms, making continuous updates, requesting strong passwords from users, authenticating users, and ensuring users of their privacy during registration should be carried out.

It suggests in future studies that the experience of users, including managers, healthcare providers, and people, in using apps in different areas of the health system during the COVID-19 period, should be studied phenomenologically, to use their results in possible future crises.
