The mobile market is tremendously increasing and has achieve a range where some software company cannot disregard the need to contribute in it any longer. Designing a native mobile application entails lots of resources and this, might affect some of the issues with development and deployment.

At present, there are different mobile device manufacturers which have different devices and development tools. The main solution to solve this issue would be to design a cross-platform application which exist on all mobile operating systems (OS), as it operates in a some browser and consequently, can reach the major possible number of end-users.

Mobile devices are the oncoming train of the future of computing. Some of the issues when developing a mobile application is basically how to build mobile apps that are applicable to many mobile devices.

In generally, there are different mobile devices today, with different operating systems, such as IOS (Apple), Android (Samsung , HTC) , Blackberry OS .

All these devices has one major difference which are the screen sizes and different attributes. Users prefers to make use of any mobile devices of their choice but everyone it would be amazing accessing a particular mobile apps on different devices.

Furthermore, developing a mobile app that runs on different devices requires the cross platform capability to brand more mobile apps accessible to users.

Over the last years software companies developed their own mobile platform with specific tools and application market (See Table 1) illustrates different mobile platform , programming languages, developers environment and application stores. The competition of mobile platform has enabled the large and rapid increase of mobile market .

The main aim of this thesis is to create a guideline for designing user-friendly cross-platform applications, taking advantages of multiple browsers and device capabilities. This guideline is based on the literature research and mobile usability.

The purpose of this section is to provide an overall base of mobile platforms, the problem discussion as well as overall purpose and research questions. An endeavour in this section is to provide relevant literature relating to some of the research questions which focuses more on cross-platform application and user experience (UX).

- Cross-Platform Framework

This section discusses one of the research questions in the thesis listed (Refer RQ.6).

At present, In the mobile industry there are different kinds of mobile devices in the market that uses different platforms or operating system (OS) such as iOS (Apple), Android(Google), Blackberry and Windows mobile (ndottech, 2013)

Developers prefers to choose a platform that aids them to develop the applications in one common language that would be supported by all the popular platforms. This is called as the cross platform mobile development.

Across the world presently, some mobile application developers have started adopting PhoneGap framework to develop some awesome applications that runs on various mobile platforms. Developers can also use PhoneGap-Build that offered by this framework to build and accumulate applications without using SDKs, hardware and other tools. One can also access different functions like camera, compass, notifications, accelerometer and more while developing application on this framework

(mobileappsdevelopmentmart, 2013).

Cross platform mobile application development provides great result to the developer. At present, developer prefers to run some apps in different platform using various tools such as:




Rhomobile (ezinemark, 2013).

Based on research on (PhoneGap Framework : A Godsend Technology To Develop Cross-Platform Apps. mobileappsdevelopmentmart, 2013) it is obvious that most software companies have adopted the use of PhoneGap tool and other cross-platform framework in other to develop different mobile platforms.

- Why Choosing Cross Platform Mobile Application Development Over Native

This section discusses one of the research questions in the thesis listed (Refer RQ.3)

As mobile industry embraces multiple platforms, a lot of mobile phone users are exceedingly increasing. Cross Platform development are being used in every field these days.

a cross-platform application can deliver the same results as a native application if designed and developed in an efficient and user friendly way, is sure going to get in the hands of millions. It is up to the developer to handle things in a good standard and attribute to come up with an app that is perfect (techblis, 2013)

Some of the apps resulted from cross-platform mobile development technologies might be slower than regular ones..

In "Pro Smartphone Cross-platform development" (Allen, et al., 2010, p. 5) the authors states that even though it is possible for developers to write other programming languages for native applications such as java, Objective C and C#, still they don't ideally make use of all the capabilities of a particular Smartphone device.

The reason for choosing a cross-platform application is rather simple. Brian Fling (Fling, 2009, p. 150), states that if an application does not need any features like using cameras, accelerometers, accessing file system, using locations in that sense, it should be developed as cross-platform application. And it will also reduce the cost of development and deployment.

- Mobile Usability

This section discusses one of the research questions in the thesis listed (Refer RQ.5) which is about cross-platform design and usability.

The usage of mobile devices is increasing ever year, same thing applies to users expectations of the mobile user experience. Generally, users prefer applications that are easy to work with, access it quickly and features attractive user interfaces. Applications designed, have to know what users want to achieve and to support them in carrying out any task. As easy as possible, this is one of the biggest challenges of a designer's job.

As a result, the main aim of this section is to provide an introduction to the topic of usability, which is very important to users and the principles of user interface design, which helps to design user-centered applications.

All the major operating systems have unique looks that serve different purposes. Apple operating system goes for a clean user interface which facilitates higher usability. it provides much of the experience people are looking for (Apple, 2013).

Android operating system makes a choice from a range of possibilities for something that is more functional and productive. Android provides a variety of pre-build UI components such as structured layout objects and UI controls. Also provides other user interface (UI) modules for special interfaces such as dialogs, notifications, and menus(Android, n.d)

Microsoft's Windows Phone's Metro interface is fast and meant to convey as much information as possible. Windows Phone provides a rich assortment of controls, textbox and text block (Microsoft, 2013).

Cross platform applications are not built with keeping a single user interface, they are developed for multiple platforms. So, they are not able to capitalise on the strengths of one interface and hence lose out in the long run (theappentrepreneur, 2012).

When designing an application, there are some constraints which developers and designers must take into consideration when designing and developing for mobile. If device type is the broadest of these, then screen size, differing form factor and physical user interface are part of pictures as well.

In-other to design a better mobile user experience, it is essential to understand the user point of view, how they behave in relation to the mobile experience that will be delivered and in relation to the entire mobile web experience (mobiforge, 2013).

Also Carol Barnum (Barnum, 2011, p. 11) analyzed this rather formal definition and highlights the importance of following elements of the previous usability definition which are as follows :

Specific users - the importance of specific users is that the focus is not on all users, but only on the target group for the particular product

Specific goals - specific goals mean that the product's goals are identical with those of its users

Specific context of use - users are using the application in a certain environment and it is essential that the application is designed to be used under those terms.

According to Jacob Nielsen describes Usability as a property of user interface with multiple components, which includes the following attributes learnability, efficiency, memorability, errors and satisfaction (Nielsen, 1993, p. 26).

(Barnum, 2011, p. 6). also describes it as how can effectiveness, satisfaction be measured. Usability can be measured in such a way where multiple users are trying to achieve a set of predefined tasks.

PhoneGap: Excellent Mobile App Development Framework

An excellent cross-platform mobile application development framework, PhoneGap is an extremely popular framework that created by Nitobi software, and later, it was acquired by Adobe in the year 2011.

By using this framework, mobile app developers are able to create lots of mobile applications for different mobile platforms like BlackBerry, Android, iOS, Palm, Bada, Symbian, Windows and more. PhoneGap make s it easily possible for mobile app developers to create lots of mobile applications that support various mobile platforms without any hassle.

Before, it was not possible to develop only one application that supports with different mobile platforms; however, PhoneGap has helped a lot to developers as well as businessmen to save their time and money. With the help of JavaScript, CSS and HTML, PhoneGap enables developers to develop any type of application without facing any obstacles. This is the most popular framework on the web that uses high standard based web technologies to develop a range of mobile apps.

These days, you can find lots of businessmen, who are using PhoneGap framework in order to develop their multi device supported application by which they can save their lots of money. Now, mobile developers can easily create fruitful and resourceful apps as PhoneGap carries latest features and functions that make development process easy. Therefore, new and inexperienced developers can also use this framework and gain a variety of benefits. No matter, whether you are looking to develop a business app or an entertainment app, PhoneGap allows you to create any application that best meets your requirements.

Appendix 3.


This article focuses on designing the user experience for mobile websites accessed from mobile phones with small screens, though the process can be applied to building apps as well. As a Web designer, the good news is that the process is similar to designing desktop websites - with some additional mobile-only considerations that go hand-in-hand with small screens, device features and constraints, and connectivity issues. The user-centered mobile design life cycle can be thought of as an ongoing process as shown below

User-Centered Mobile Design Starts With The User User-centered design relies on user involvement throughout the design process, leading to a solution that users will find useful and want to use. To achieve that, you first need to have a clear understanding of your users, grouped into a prioritized set of user groups whose needs can be thought of individually. For a pharmaceutical company, those groups could be patients, healthcare professionals and caregivers, with the first two groups being the primary user groups, and caregivers being a secondary user group with very similar needs to patients. Identifying your key user groups and creating personas will help you design better for your main users, the way BBC did when building their future mobile strategy.
