Technology, Privacy, and User Opinions of COVID-19 Mobile Apps for Contact Tracing: Systematic Search and Content Analysis

Background Many countries across the globe have released their own COVID-19 contact tracing apps. This has resulted in the proliferation of several apps that used a variety of technologies. With the absence of a standardized approach used by the authorities, policy makers, and developers, many of these apps were unique. Therefore, they varied by function and the underlying technology used for contact tracing and infection reporting. Objective The goal of this study was to analyze most of the COVID-19 contact tracing apps in use today. Beyond investigating the privacy features, design, and implications of these apps, this research examined the underlying technologies used in contact tracing apps. It also attempted to provide some insights into their level of penetration and to gauge their public reception. This research also investigated the data collection, reporting, retention, and destruction procedures used by each of the apps under review. Methods This research study evaluated 13 apps corresponding to 10 countries based on the underlying technology used. The inclusion criteria ensured that most COVID-19-declared epicenters (ie, countries) were included in the sample, such as Italy. The evaluated apps also included countries that did relatively well in controlling the outbreak of COVID-19, such as Singapore. Informational and unofficial contact tracing apps were excluded from this study. A total of 30,000 reviews corresponding to the 13 apps were scraped from app store webpages and analyzed. Results This study identified seven distinct technologies used by COVID-19 tracing apps and 13 distinct apps. The United States was reported to have released the most contact tracing apps, followed by Italy. Bluetooth was the most frequently used underlying technology, employed by seven apps, whereas three apps used GPS. The Norwegian, Singaporean, Georgian, and New Zealand apps were among those that collected the most personal information from users, whereas some apps, such as the Swiss app and the Italian (Immuni) app, did not collect any user information. The observed minimum amount of time implemented for most of the apps with regard to data destruction was 14 days, while the Georgian app retained records for 3 years. No significant battery drainage issue was reported for most of the apps. Interestingly, only about 2% of the reviewers expressed concerns about their privacy across all apps. The number and frequency of technical issues reported on the Apple App Store were significantly more than those reported on Google Play; the highest was with the New Zealand app, with 27% of the reviewers reporting technical difficulties (ie, 10% out of 27% scraped reviews reported that the app did not work). The Norwegian, Swiss, and US (PathCheck) apps had the least reported technical issues, sitting at just below 10%. In terms of usability, many apps, such as those from Singapore, Australia, and Switzerland, did not provide the users with an option to sign out from their apps. Conclusions This article highlighted the fact that COVID-19 contact tracing apps are still facing many obstacles toward their widespread and public acceptance. The main challenges are related to the technical, usability, and privacy issues or to the requirements reported by some users.

BACKGROUND Currently, the use of smartphones to deliver health-related content has experienced a rapid growth, with more than 165,000 mobile health (mHealth) applications currently available in the digital marketplace such as iOS store and Google Play. Among these, there are several mobile applications (mobile apps) that offer tools for disease prevention and management among older generations. These mobile apps could potentially promote health behaviors which will reduce or delay the onset of disease. However, no review to date that has focused on the app marketplace specific for older adults and little is known regarding its evidence-based quality towards the health of older adults. OBJECTIVE The aim of this review was to characterize and critically appraise the content and functionality of mobile apps that focuses on health management and/or healthy lifestyle among older adults. METHODS An electronic search was conducted between May 2019 to December 2019 of the official app store for two major smartphone operating systems: iPhone operating system (iTunes App Store) and Android (Google Play Store). Stores were searched separately using predetermined search terms. Two authors screened apps based on information provided in the app description. Metadata from all included apps were abstracted into a standard assessment criteria form. Evidenced based strategies and health care expert involvement of included apps was assessed. Evidenced based strategies included: self-monitoring, goal setting, physical activity support, healthy eating support, weight and/or health assessment, personalized feedback, motivational strategies, cognitive training and social support. Two authors verified the data with reference to the apps and downloaded app themselves. RESULTS A total of 16 apps met the inclusion criteria. Six out of 16 (37.5%) apps were designed exclusively for the iOS platform while ten out of 16 (62.5%) were designed for Android platform exclusively. Physical activity component was the most common feature offered in all the apps (9/16, 56.3%) and followed by cognitive training (8/16, 50.0%). Diet/nutrition (0/16, 0%) feature, however, was not offered on all reviewed mobile apps. Of reviewed apps, 56.3% (9/16) provide education, 37.5% (6/16) provide self-monitoring features, 18.8% (3/16) provide goal setting features, 18.5% (3/16) provide personalized feedback, 6.3% (1/16) provide social support and none of the reviewed apps offers heart rate monitoring and reminder features to the users. CONCLUSIONS All reviewed mobile apps for older adults in managing health did not focused on diet/nutrition component, lack of functional components and lack of health care professional involvement in their development process. There is also a need to carry out scientific testing prior to the development of the app to ensure cost effective and its health benefits to older adults. Collaborative efforts between developers, researchers, health professionals and patients are needed in developing evidence-based, high quality mobile apps in managing health prior they are made available in the app store.

Abstract Background The increased use of smartphone applications across healthcare specialties has been particularly relevant in dermatology, with dermatology related applications widely available on mainstream application stores. We reviewed published literature regarding melanoma-related applications, and the number and types of such applications available for download. Methods A literature search of “dermatology”, “smartphone” and “melanoma” was conducted to identify publications assessing applications of interest. “Melanoma” was searched in Apple’s (iOS) “App Store” and Google’s “Google Play”, and application purposes and ratings were analysed. Results 54 of the 63 literature search results explored smartphone use in relation to melanoma, describing benefits including quicker patient access to care, reduced referrals and hence unnecessary consultations, and improved accessibility to information. However, concerns include insufficient image quality, privacy issues related to encryption, and diagnostic inaccuracy. Searches on the Google Play and iOS stores identified 249 and 51 apps respectively. 25% of Google Play results were categorised as clinical tools, 17% as educational, and 58% as recreational. The corresponding results for the App store were 92%, 6% and 2%. 81% of the educational apps and 92% of the clinical management apps related to dermatology and melanoma on Google Play, whereas all of the clinical management apps and 67% of the education apps on the App store were of relevance. Conclusion The results illustrate the widespread availability of applications related to melanoma, particularly for educational and clinical purposes. Standardising photographing techniques, improving diagnostic accuracy, and privacy issues are important aspects to consider and warrant further investigation.

AbstractDue to the convenience of access-on-demand to information and business solutions, mobile apps have become an important asset in the digital world. In the context of the COVID-19 pandemic, app developers have joined the response effort in various ways by releasing apps that target different user bases (e.g., all citizens or journalists), offer different services (e.g., location tracking or diagnostic-aid), provide generic or specialized information, etc. While many apps have raised some concerns by spreading misinformation or even malware, the literature does not yet provide a clear landscape of the different apps that were developed. In this study, we focus on the Android ecosystem and investigate Covid-related Android apps. In a best-effort scenario, we attempt to systematically identify all relevant apps and study their characteristics with the objective to provide a first taxonomy of Covid-related apps, broadening the relevance beyond the implementation of contact tracing. Overall, our study yields a number of empirical insights that contribute to enlarge the knowledge on Covid-related apps: (1) Developer communities contributed rapidly to the COVID-19, with dedicated apps released as early as January 2020; (2) Covid-related apps deliver digital tools to users (e.g., health diaries), serve to broadcast information to users (e.g., spread statistics), and collect data from users (e.g., for tracing); (3) Covid-related apps are less complex than standard apps; (4) they generally do not seem to leak sensitive data; (5) in the majority of cases, Covid-related apps are released by entities with past experience on the market, mostly official government entities or public health organizations.

ObjectivesOur goal was to gain insights into the user reviews of the three COVID-19 contact-tracing mobile apps, developed for the different regions of the UK: ‘NHS COVID-19’ for England and Wales, ‘StopCOVID NI’ for Northern Ireland and ‘Protect Scotland’ for Scotland. Our two research questions are (1) what are the users’ experience and satisfaction levels with the three apps? and (2) what are the main issues (problems) that users have reported about the apps?MethodsWe assess the popularity of the apps and end users’ perceptions based on user reviews in app stores. We conduct three types of analysis (data mining, sentiment analysis and topic modelling) to derive insights from the combined set of 25 583 user reviews of the aforementioned three apps (submitted by users until the end of 2020).ResultsResults show that end users have been generally dissatisfied with the apps under study, except the Scottish app. Some of the major issues that users have reported are high battery drainage and doubts on whether apps are really working.DiscussionTowards the end of 2020, the much-awaited COVID-19 vaccines started to be available, but still, analysing the users’ feedback and technical issues of these apps, in retrospective, is valuable to learn the right lessons to be ready for similar circumstances in future.ConclusionOur results show that more work is needed by the stakeholders behind the apps (eg, apps’ software engineering teams, public-health experts and decision makers) to improve the software quality and, as a result, the public adoption of these apps. For example, they should be designed to be as simple as possible to operate (need for usability).

Background Mobile health apps are used to improve the quality of health care. These apps are changing the current scenario in health care, and their numbers are increasing. Objective We wanted to perform an analysis of the current status of mobile health technologies and apps for medical emergencies. We aimed to synthesize the existing body of knowledge to provide relevant insights for this topic. Moreover, we wanted to identify common threads and gaps to support new challenging, interesting, and relevant research directions. Methods We reviewed the main relevant papers and apps available in the literature. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology was used in this review. The search criteria were adopted using systematic methods to select papers and apps. On one hand, a bibliographic review was carried out in different search databases to collect papers related to each application in the health emergency field using defined criteria. On the other hand, a review of mobile apps in two virtual storage platforms (Google Play Store and Apple App Store) was carried out. The Google Play Store and Apple App Store are related to the Android and iOS operating systems, respectively. Results In the literature review, 28 papers in the field of medical emergency were included. These studies were collected and selected according to established criteria. Moreover, we proposed a taxonomy using six groups of applications. In total, 324 mobile apps were found, with 192 identified in the Google Play Store and 132 identified in the Apple App Store. Conclusions We found that all apps in the Google Play Store were free, and 73 apps in the Apple App Store were paid, with the price ranging from US $0.89 to US $5.99. Moreover, 39% (11/28) of the included studies were related to warning systems for emergency services and 21% (6/28) were associated with disaster management apps.

Mobile application stores have become very popular, and the two most popular, Google Play and Apple App Store, both have over a million applications (apps) available. Social media is extensively used for marketing products and services; but, its true potential, in service and product acceleration, has not been researched much. This paper studies the differences in actions between successful and less successful app developers and especially their social media use in accelerating applications and its impact on success. In this study, a longitudinal analysis is performed on 682 applications, from four Google Play categories, at three data points. This study concludes that almost 50% of the analyzed applications use some form of social media to promote their app, and that successful apps use social media more actively than less successful ones. The qualitative analysis of the apps sheds some light as to why some apps succeed without social media use, and why some fail while using it.

A Review of: Tummon, N., & McKinnon, D. (2018). Attitudes and practices of Canadian academic librarians regarding library and online privacy: A national study. Library and Information Science Research, 40(2), 86-97. https://doi.org/10.1016/j.lisr.2018.05.002 Abstract Objective – To assess attitudes of Canadian academic librarians regarding online privacy issues and to gauge their knowledge of related procedures and policies at their institutions. Design – Attitudinal online survey in English. Setting – English-language academic libraries in 10 Canadian provinces. Subjects – English-speaking academic librarians across Canada. Methods – Survey, based on Zimmer’s 2014 study of librarians in the United States of America, announced via email to 1,317 potential participants, managed using LimeSurvey, and available from April 7 to May 5, 2017. In 28 optional multiple choice or Likert scale questions, the survey prompted participants to express their attitudes regarding online privacy scenarios and privacy-related library practices, including patron data collection. Results were analyzed in Microsoft Excel and SPSS. Main Results – The survey response rate was 13.9% (183 respondents). Job position, age, or geographic location did not appear to influence attitudes towards privacy, with almost all respondents strongly agreeing or agreeing that individuals should control who sees their personal information (96.2%) and that companies collect too much such information (97.8%). Respondents voiced slightly less concern about government information collection, but nearly all respondents agreed that governments should not share personal information with third parties without authorization and that companies should only use information for the purposes they specify. When asked if privacy issues are more important today than five years ago, 69.9% of respondents said they were more concerned and 78.1% noted they knew more than five years before about privacy-related risks. Regarding online behaviour, 53.3% of respondents felt web behaviour tracking is both beneficial and harmful, with 29.1% considering it harmful, and 13.7% finding it neither beneficial nor harmful. Online shopping and identify theft, social media behaviour tracking, search engine policy display, and personal information sharing were also areas of concern for respondents, with the majority noting they were somewhat or very concerned about these issues. In terms of library practices, most respondents strongly agreed that libraries should not share personal information, circulation records, or Internet use records with third parties unless authorized, though 33% of respondents noted they could neither agree nor disagree that libraries are doing all they can to prevent unauthorized access to such information. The majority of respondents strongly agreed or agreed that libraries should play a role in educating patrons about privacy issues. Many respondents (68.9%) did not know if their libraries had practices or procedures for dealing with patron information requests from law enforcement or governmental representatives. The majority of respondents did not know if patrons at their libraries had inquired about privacy issues, 42.3% did not know if their libraries communicate privacy policies to patrons, and 45.4% noted their libraries did not inform patrons about library e-resource privacy policies. Many respondents (55.2%) had attended educational sessions about online privacy and surveillance in the past five years, while 52.2% noted their libraries had not hosted or organized such sessions over the same period. Conclusion – Survey participants showed concern about online and patron privacy, though their lack of knowledge about local procedures and policies highlights a potential need for enhanced privacy education.

Mhealth Apps

BACKGROUND Mobile health (mHealth) apps used for promotion raise important questions about privacy of sensitive personal health information and digital advertising literacy. Although it is common that different types of organizations support mHealth apps for promotional purposes (e.g., sponsorship, owned apps), there is little understanding of users’ perceptions regarding the safety of personal data stored in mobile apps. Persuasion knowledge, or recognition of a sponsor’s presence, characteristics, intents, competencies, and persuasion tactics, is crucial to investigate because the abundance of mHealth apps makes it difficult for users to identify their true purpose and estimate privacy-related risks. OBJECTIVE The aim of this study is to investigate smartphone users’ persuasion knowledge related to mHealth apps used as a promotional strategy by commercial, government, and non-profit/non-governmental organizations. This study also examines users’ willingness to share demographic and health information via those apps. METHODS In-depth semi-structured interviews were conducted at a large Midwestern university in the United States. Smartphone users (N = 25) were recruited from the local community. RESULTS Participants had a high level of persuasion knowledge regarding the types of app-supporting organizations and their promotional intents, but only after being probed. Participants expressed concerns about losing control over sharing personal information with mHealth apps supported by different organizations. They used alternative digital identities to protect themselves from privacy invasion, security risks, and advertising spam associated with mHealth app use. Yet, participants did not engage in reading privacy policies and statements when downloading such apps. Participants were prone to share greater amounts of personal information with the apps backed by non-profit and government agencies than by commercial companies. They were willing to “trade” some personal information for high quality and functionality of commercially supported mHealth apps. Participants inclined to share lesser than greater amounts of personal information with sponsored/branded mHealth apps and indicated that information for sharing should be more general than specific. There was a sense of fatalism in discussing health-related risks linked to mHealth app usage; and some participants did not perceive the risks to be serious. CONCLUSIONS Despite high levels of persuasion knowledge related to using mHealth apps for promotion, smartphone users didn’t show a great effort in evaluating app providers and app financial sources. This may bring serious consequences related to privacy of personal and health information as it can be continuously collected and managed by the supporting organizations and third-parties. Discussion of and recommendations for safe and ethical uses of mHealth apps associated with organization/company promotional strategies and privacy protection are provided. Theoretical implications are discussed in the context of the persuasion knowledge model and dual-processing theories.

Background In response to health concerns about vaping devices (eg, youth nicotine use, lung injury), Apple removed 181 previously approved vaping-related apps from the App Store in November 2019. This policy change may lessen youth exposure to content that glamorizes vaping; however, it may also block important sources of information and vaping device control for adults seeking to use vaping devices safely. Objective Understanding the types of nicotine and cannabis vaping–related apps still available in the competing Google Play Store can shed light on how digital apps may reflect information available to consumers. Methods In December 2019, we searched the Google Play Store for vaping-related apps using the keywords "vape" and "vaping" and reviewed the first 100 apps presented in the results. We reviewed app titles, descriptions, screenshots, and metadata to categorize the intended substance (nicotine or cannabis/tetrahydrocannabinol) and the app’s purpose. The most installed apps in each purpose category were downloaded and evaluated for quality and usability with the Mobile App Rating Scale. Results Of the first 100 apps, 79 were related to vaping. Of these 79 apps, 43 (54%) were specific to nicotine, 3 (4%) were specific to cannabis, 1 (1%) was intended for either, and for the remaining 31 (39%), the intended substance was unclear. The most common purposes of the apps were making do-it-yourself e-liquids (28/79, 35%) or coils (25/79, 32%), games/entertainment (19/79, 24%), social networking (16/79, 20%), and shopping for vaping products (15/79, 19%). Of the 79 apps, at least 4 apps (5%) paired with vaping devices to control temperature or dose settings, 8 apps (10%) claimed to help people quit smoking using vaping, and 2 apps (3%) had the goal of helping people quit vaping. Conclusions The majority of vaping-related apps in the Google Play Store had features either to help users continue vaping, such as information for modifying devices, or to maintain interest in vaping. Few apps were for controlling device settings or assisting with quitting smoking or vaping. Assuming that these Google Play Store apps were similar in content to the Apple App Store apps that were removed, it appears that Apple’s ban would have a minimal effect on people who vape with the intention of quitting smoking or who are seeking information about safer vaping via mobile apps.

Free Word

This research examines drivers of consumer word of mouth (WOM) in free-product settings, revealing fundamental differences with traditional, paid-product settings. The authors build and investigate a theoretical model that highlights two unique characteristics of free products (reciprocity motivation and diminished adoption risk) and considers their implications for WOM sharing. Results of a retrospective survey, two controlled experiments, and an analysis of more than 5,000 mobile apps at Google Play and Apple’s App Store reveal that consumers are generally more likely to share their opinions of free products than paid products, because of feelings of reciprocity toward the producer. However, this difference is reduced when prior consumer WOM is low in volume and highly disperse, signaling greater adoption risk. These findings contribute to nascent understanding of free-product marketing while offering new insights for catalyzing consumer WOM.
