There were several various and distinct platforms for development of those features. This was known as cross platform approach; today we have a new approach which is known as progressive web application which can be implemented through a set of latest technologies. This application can then be used on all or almost all platforms. In this research paper we suggest that progressive web applications will suffice the need for native applications. First, we introduce the topic then we will scrutinize the performance and compare the recent specifications provided by each of the technologies for web application development across platforms. Keywords : Progressive Web Apps, Cross-platform, Mobile Web I. INTRODUCTION Source code for the native [1] applications as the name suggests is specific for a particular application therefore it is known as non-reusable code; reusability of code is desired not only in a particular application but also across platforms; this functionality is not served by native applications. This results in separate projects and separate environment for developers working on similar or even sometimes same applications. Earlier companies had to employee specialised human resources for native application development required for each platform. Solution to this problem has been made possible by progressive web application [2] for cross or inter- platform development; development time as well as time to deploy an application to market is also reduced. Therefore progressive web applications provide for low budget, low human resources etc. Search applications can be developed by using open sources or paid sources. Popular frameworks include phonegap, react native. Progressive web applications not only allow cross platform development across websites but also provide with features such as background synchronisation, offline support, home screen installation for mobile platforms. Progressive web applications hence unify internet experience on mobile as well as other devices, such devices may include laptops, tablets and other devices with varying pixel scope. Web applications can now be distributed without web app
