The mobile apps have been reaching a huge success on the mobile market. This opportunity attracted a lot of interested companies to have their own optimized mobile apps for all major mobile operation systems. However, these developments are expensive when developed natively for each mobile platform. New improvements done on the web technologies, allowed more features and capabilities than previously was only possible on apps that was developed natively. This started new possibilities on consolidate all developments only on web apps, that are apps that runs on web browsers. This paper intends to understand which evolutions, capabilities and limitations exists on developing a web app to run in all devices. We present the new concept of Progressive Web App, created by Google, in a way to normalize all web developments. It will be introduced the major advantages on developing the apps centralized as a Progressive Web App, comparing on developing the same solution for each different mobile platform. It will be also described the current state of web technologies and in which preferable scenarios the Progressive Web Apps are a strong alternative to the mobile native apps.

Progressive web App is a web-based application development that includes the application of the latest technology from a browser that can be accessed quickly into one application without having to install. Progressive web applications can run like mobile applications in general, and the user interface is like using native applications. Progressive web app was invented in 1990. Progressive web App uses the latest Technology to produce web apps that provide a better User Experience and User Interface than mobile native. Progressive web app that is supported by a system called Service Worker, where the technology provides Offline Functionality, Notifications, Content Updates, Connectivity Changes and others. So that in a slow connection or an unstable connection you can access websites quickly and have the same appearance as the last time you opened the application via a Web Browser. This progressive web app can optimize web app performance to allow users to have an accessible experience with quickly and easily through browsers such as notebooks, personal computers or through mobile devices. This progressive web app is a service worker that allows a web app that can be run through all existing browsers and has a fairly simple and transparent process. So that the page that is opened, on the service worker site which is a proxy client that can be written in javascript, as well as being able to cache the assets needed for offline support which can determine certain events to activate the service worker such as push notifications, camera, and background sync. Keywords : Progressive Web Apps, Web, User Interface, Native Apps, User Experience

Context. Mobile web apps represent a large share of the Internet today. However, they still lag behind native apps in terms of user experience. Progressive Web Apps (PWAs) are a new technology introduced by Google that aims at bridging this gap, with a set of APIs known as service workers at its core. Goal. In this paper, we present an empirical study that evaluates the impact of service workers on the energy efficiency of PWAs, when operating in different network conditions on two different generations of mobile devices. Method. We designed an empirical experiment with two main factors: the use of service workers and the type of network available (2G or WiFi). We performed the experiment by running a total of 7 PWAs on two devices (an LG G2 and a Nexus 6P) that we evaluated as blocking factor. Our response variable is the energy consumption of the devices. Results. Our results show that service workers do not have a significant impact over the energy consumption of the two devices, regardless of the network conditions. Also, no interaction was detected between the two factors. However, some patterns in the data show different behaviors among PWAs. Conclusions. This paper represents a first empirical investigation on PWAs. Our results show that the PWA and service workers technology is promising in terms of energy efficiency.

Growing use of the cell phones and tablets over the computer for humans’ daily life has increased the development of mobile apps. Different paradigms have been introduced to develop a mobile app. Up till now, the major paradigms have been introduced are native apps, hybrid apps, web app and the new trend namely progressive web app (PWA). Each methodology has its pros and cons. This paper discusses about native development issues and how web app aimed to solve these problems. The hybrid apps will be discussed as a solution of cross-platform development problem of native apps. In addition, problems of web apps and the gap between web app and native apps will be introduced. PWA is supposed to bridge the gap between native apps and web apps. The main technologies –service worker- will also be discussed.

Multiple Sclerosis (MS) is a chronic neurodegenerative disorder. People living with MS (plwMS) require long-term, multidisciplinary care in both clinical and community settings. MS-specific mHealth interventions have advanced in the form of clinical treatments, rehabilitation, disease monitoring and self-management of disease. However, mHealth interventions for plwMS appear to have limited proof of clinical efficacy. As native mobile apps target specific mobile operating systems, they tend to have better interactive designs leveraging platform-specific guidelines. Thus, to improve such efficacy, it is pivotal to explore the design characteristics of native mobile apps used for plwMS. This study aimed to explore the design characteristics of native mobile apps used for adults living with MS in academic settings. A scoping review of studies was conducted. A literature search was performed through PubMed, CINAHL, MEDLINE and Cochrane Library. Per native mobile apps, characteristics, persuasive technology elements and evaluations were summarized. A total of 14 native mobile apps were identified and 43% of the identified apps were used for data collection (n=6). Approximately 70% of the included apps involved users (plwMS) whilst developing (n=10). A total of three apps utilized embedded sensors. Videos or photos were used for physical activity interventions (n=2) and gamification principles were applied for cognitive and/or motor rehabilitation interventions (n=3). Behavior change theories were integrated into the design of the apps for fatigue management and physical activity. Regarding persuasive technology, the design principles of primary support were applied across all identified apps. The elements of dialogue support and social support were the least applied. The methods for evaluating the identified apps were varied. The findings suggest that the identified apps were in the early stages of development and had a user-centered design. By applying the persuasive systems design model, interaction design qualities and features of the identified mobile apps in academic settings were systematically evaluated at a deeper level. Identifying the digital functionality and interface design of mobile apps for plwMS will help researchers to better understand interactive design and how to incorporate these concepts in mHealth interventions for improvement of clinical efficacy.

App development is a steadily growing industry. Progressive web apps (PWAs) constitute a technology inspired by native and hybrid apps; they use web technologies to create web and mobile apps. Based on a service worker, a caching mechanism, and an app shell, PWAs aim to offer web apps with features and user interfaces similar to those of native apps. Furthermore, technological development has created a greater need for accessibility. An increasing number of websites, even government ones, are overlooking the need for equal access to new technologies among people with disabilities. This article presents, in a systematic review format, both PWAs and web accessibility and aims to evaluate PWAs’ effectiveness as regards the corresponding accessibility provided.

The proposed system uses Natural Language Processing (NLP) and Deep Learning (DL) techniques to extract voice data and translate it to text during medical consultations. Iterative model was adopted in the design of the system and the user interfaces was implemented by using NLP techniques, especially speech recognition and natural language understanding. Deep learning algorithm shows a great ability to build clinical decision support systems by extracting various information for medical diagnosis and produce result is few seconds. The result form the system testing shows that the installation size of the Progressive Web App (104 KB) is 42 times smaller than the native Android app (4.37 MB). In terms of render-speeds, the PWA rendered different results. The native app will launch the Android activity after 1408 ms after app icon tap (launch), while the progressive web app launches the application in 230 ms. The advent of cross-platform application development frame-works have made it much easier to create applications for multiple platforms for mobile devices. In spite of reduced learning effort, usually lower costs, and a faster time-to-market cross-platform methods always do not prevail in most cases. Although there are normal exclusions – like graphic-intensive games, which should to be programmed with the native software development kits (SDKS), choice between native apps, cross-platform generated ones, and Web apps can remain delicate. Whereas many diverse efforts have been made with respect to how cross-platform development frameworks ought to work, no technology is deemed unequivocally superior than the others. But a cross-platform mobile app has got an edge over native app development. It also recommends that developers adopt this technology of mobile app development due to its huge gains.

Objectives: This research study provides an analysis model which is used to analyze the requirements of mobile native apps contextually under any domain. Methods/Statistical Analysis: Based on the background study, the research process have taken three research approaches and also have identified various activities which are performed among a native mobile app user and mobile native apps and formed them into questionnaires which are sent to different mobile native app developers of different software industries.

A comparative study on the energy consumption of Progressive Web Apps

Progressive Web App (PWA) is a new approach to the development of mobile applications (apps) which was proposed by Google in 2015. It combines technology resources of both web and native apps. Meta-design is an End-User Development (EUD) approach from which end-users participate actively in a system's design process. Yet, PWAs are a recent technology and the impacts of associating EUD and PWAs has been little exploited. As the traditional PWA approach is limited regarding users acting as co-designers, we propose the PWA-EU approach, an extension of the traditional PWA architecture that includes EUD concepts. PWA-EU provides contributions in two lenses. First, the proposal was designed to be used by developers on the design/development time. Second, the app developed using PWA-EU approach will allow end-users to select design preferences, which makes them participants of the app's design. This active participation of end-users on the design is possible due to the meta-design concepts present on the PWA-EU approach. In this article, we present the PWA-EU approach and its evaluation in the perspective of developers/designers. For the evaluation, we grouped participants according to their professional background. The results also indicate that novice developers had a reasonable performance with only one hour of training.We conclude that even novice developers could achieve better performance in a real-life environment, in which they would have more time.
