Application developed using mobile application development concept is called mobile app. All the applications used in Mobile Devices are categorized into native applications or apps and web applications or apps. A web application for mobile phone is the web based version which is used by browser of mobile phone devices. A native application for mobile phone is designed for specific mobile devices and system software that device. There is another types of app used in mobile phones called Hybrid application or app. It combines the best features of both types of apps. Now the designer only develops hybrid application & it can be used in any types of mobile devices. It greatly reduces the cost of development and also it saves lot of time. In this paper we develop The Rest House App for the Indian Railways. Its main aim is to perform different tasks related to rest house of Indian Railway efficiently and perfectly. We uses Ionic tool for the app development because with this tool hybrid app is generated which can be executed on all the mobile platforms. Keywords: Mobile Computing, Mobile App, Web App, Native App, Hybrid app, Ionic Tool. 1. INTRODUCTION Today is era of Mobile Computing. In this type of computing a user of any device need not to be in fixed location instead the user travel from one place to another without lost of connectivity. If we use our cell phone to send a text message, email someone, or reach the Internet, we are using mobile computing [1]. If we take our laptop computer to a coffee shop and use their wireless connection to reach the Internet or communicate with others, we are using mobile computing. Mobile computing means being able to use a computing device even when we are going to locations beyond the place where we usually use a desktop computer. This includes a variety of Internet-ready, wireless devices that are easy to carry with us. When using mobile computing, researching on the Internet, or communicating with others when we are anywhere, you need three important things. They are a mobile device, a network connection, and special software applications, called apps. The number of mobile devices available is amazingly large and getting larger, and there are a couple of options that we will learn about for connecting to the Internet. We will also find that there are thousands of apps that have been created for most mobile devices. These applications can help us access information, be more productive, or enjoy games and other types of entertainment when using our device [2]. The sudden rise in smartphones and tablets penetration, the modern businesses can’t afford to not offer mobile apps to their customers that run on different platforms. When it comes to developing an app with right features along with performance indicators and platform support, things can be complicated for any software development company. Developing multiplatform apps is need of today. An application which works same on all the operating systems is known as Hybrid App. Now the designer only develops hybrid application & it can be used in any types of mobile devices. [3][4]. In this work we develop The Rest House App for the Indian Railways. Its main aim is to perform different tasks related to rest house of Indian Railway efficiently and perfectly. It performs booking of rest houses for the officials, supervisors, passengers and staffs. We uses Ionic tool for the app development because with this tool hybrid app is generated which can be executed on all the mobile platforms. 2. TYPES OF MOBILE APPLICATIONS In mobile computing a user of any device need not to be in fixed location instead the user travel from one place to another without lost of connectivity. If we use our cell phone to send a text message, email someone, or reach the Internet, we are using mobile computing. Mobile application development is used for constructing application software for small size devices that perform large types of computation for example mobile phones, notepads or tablets.
