Det här arbetet utforskar jämförelsen mellan progressiva webbapplikationer (PWA) och native mobila applikationer. Arbetet belyser ett problem som är aktuellt idag och kommer att vara ännu mer så i närmaste framtid på grund av den ständiga teknikutvecklingen och människans beroende av mobila applikationer. Användningen av mobilen har ökat kraftigt under de senaste årtiondena med mobila applikationer som integreras i människans livsstil. Denna tillväxt indikerar att utvecklingen av applikationer behöver justeras för en effektivare och säkrare metod. Även om native applikationen för närvarande leder, utmanar PWA mer än tidigare på grund av dess effektivitet och enkelhet. Genom att utveckla en PWA och en native mobilapplikation syftar denna studie på att identifiera de huvudsakliga skillnaderna. Analysens fokus var att visa de tre kritiska aspekterna, hastighet, säkerhet och utvecklingstid, med resultaten som tyder på att PWA presterar bättre i form av hastighet när den optimeras, men native mobila applikationen har en större tillgänglighet för implementering av funktioner. Dessa resultat berikar den pågående diskussionen med ytterligare förståelse för de två mest populära strategierna för att skapa en mobilapplikation och ger information om hur appscenen möjligen kan utvecklas i framtiden. / This thesis explores the comparison of progressive web applications (PWA) with native mobile applications. This thesis sheds light on an issue that is relevant today and will be even more so in the near future due to the constant advancement of technology and the growing dependence of human life on the use of mobile applications. The use of the mobile has increased significantly over the past couple of decades with the mobile application being integrated into the human lifestyle. This pattern of growth indicates that the development of the applications needs to be adjusted for an effective and more secure approach. Although the native application is currently the leading app, the PWA puts on a more extensive challenge than before due to its effectiveness and simplicity. By developing one PWA and one native mobile application, this study aims to identify the key differences. The focus of the analysis was to demonstrate the three critical aspects, speed, security and time of development with the results showing that the PWA performs better in terms of speed when being optimized, but the native mobile application has a larger access base for feature implementation. These results enrich the ongoing discussion with further understanding for the two most popular strategies of crafting a mobile application, with information about how the future of the app scene possibly evolve.

The mobile application market is becoming increasingly fragmented with the availability of multiple mobile platforms that differ in development procedures. Developers are forced to choose to support only some platforms and specific devices due to limited development resources. To address these challenges, numerous tools have been created to aid developers in building cross-platform applications, however, there is no metric to evaluate the quality of these tools. This thesis introduces a framework for evaluating the features, performance and discuss development experience of existing and future cross-platform development tools. The framework is implemented by benchmarking several tools and the results identify a disparity in the features and performance. This research is carried out in collaboration with industrial partner Desire2Learn, through an NSERC Engage Grant. / NSERC, Desire2Learn

Many desktop applications have moved away from heavy client-side programs tolighter web-based solutions served from the cloud. Mobile applications have also beentraditionally client-based in the form of native applications. With the use of HTML5,however, there is a growing shift towards web apps as opposed to native. HTML5technologies are enabling mobile apps to run in the browser with some native appfunctionality. HTML5 has received a great deal of attention since its release in 2009,there are numerous articles and discussions on the Internet. Some developers are verynegative and some are very positive towards the idea that it is a serious contender inmobile application development. This report presents research carried out to get theviews of developers as to their current use of HTML5 and how much they expect tobe developing mobile apps using HTML5 in the future. Judging by the level ofresponse gained and comments given, this is a very hot topic right now. The researchshows that HTML5 is a viable alternative to native app development but it has somelimitations and has some way to go before it could begin to replace native appdevelopment altogether.

There has been an enormous growth in the usage of smartphones in recent times. Smartphones are not limited to communication purposes. It has various applications designed as per the daily requirements of humans such as web-searching, online shopping, bank transactions, games, etc. With the increase in the usage of the smartphone, the more useful information is captured and stored by it, which raises the question of security. The goal of this research is to develop two android applications. One is a sensor detector application and the second is a screen lock application. The first application will help the user to identify all the hidden sensors and working sensors on the mobile phone. This application even describes the features and usage of every sensor in detail. Using a graphical description of each sensor which depicts the behaviour of each sensor as per environment/movement. The second application is designed using a combination of two sensors. Screen lock applications contain two main factors. One is to work properly in all cases and efficiently do the functions that are required to do. The second is to maintain a smooth inner system interaction because in addition to locking the screen this application should make sure to hide the display of all the other applications without closing the process of these applications. With the increase in the usage of the smartphone, it becomes difficult for older generations to memorize the security pattern techniques and use them. This thesis develops a simple technique in the mobile authentication android application. The thesis is developed on the Android studio platform. The background functionality of the app is coded in java using android SDK tool and frontend of the application is designed using XML files. The GENYMOTION emulator and a mobile phone are used to test the output.

This thesis aims to to see if its possible to meet some of the complex needs of people with ADHD, in the form of aiding them with remembering to complete tasks and chores. Current studies have mainly focused on either assessing or treating ADHD rather than looking at aiding people already diagnosed. In order to evaluate if the needs can be met the participants of the paper are first interviewed to determine some of the needs. A mobile application was then developed based on the data collected from the interviews and later evaluated by the participants in a second round of interviews. The result of this paper showed that these complex needs can be met, in this paper the needs managed to be met with the use of mobile notifications that server as reminders and also by letting the participants prioritize the importance of the task. However the application did not fully suit all participants and had some shortcomings which could lead to further research that looks at trying to meet more of these needs, either by continued development of the application or by mapping out what the needs are.

With rapid technology growth and a rising disabled and aging population, mobile appaccessibility is vital. Stricter accessibility laws, especially in the public sector, highlight thisemphasis. However, despite this, the body of research focusing on software practitioners’perspectives, especially concerning cross-platform development, is lacking. In this qualitativecase study, six software practitioners at the Swedish Social Insurance Agency(Försäkringskassan) were interviewed about their experience during a migration betweenmobile development technologies, with a focus on enhancing mobile application accessibility.It explores their attitude to cross-platform development, their challenges with NativeScript, across-platform framework, and preferences for native technology. To further understand theiracceptance of native technology and their rejection of cross-platform technology in thiscontext, an extension of the Technology Acceptance Model (TAM2) was used. Respondents emphasized the legal and ethical obligations for accessibility in the publicsector, with evolving standards necessitating the selection of the most appropriate technologyfor the task. Prioritizing accessibility early on in public sector app development helps avoidadditional expenses later on. It's also possible that private sector apps may be required to shifttowards greater inclusivity in the future. The team successfully addressed previous accessibility issues using native technology, whichinfluenced the organization to migrate. Moreover, respondents believed that nativetechnology enhances professional image, especially as the industry favors it over unknowncross-platform frameworks. They perceived that cross-platform frameworks might lackthorough documentation and community support, making it more difficult to manage andimplement accessibility. Additionally, respondents are alarmed by the uncertain nature ofcross-platform technology, which can result in outdated frameworks and unworkablecodebases. It's crucial to consider the duration of the project, its accessibility needs, and theavailable support for implementing accessibility when deciding on mobile developmenttechnologies. These findings are valuable for various stakeholders, such as consultants,researchers and policy-makers.
