The credit, on the one hand goes to the advanced network connectivity services which are enhancing day by day for high-speed transmission, advanced multimedia access and global roaming in mobile phones and handsets which are used as a means to connect to the Internet \ IP networks for voice and video calls, downloading and uploading data and to surf the internet. On the other hand Smart phones are also given credits which are available in compact size, lightweight that can be carried easily. Its OLED and high-resolution touchscreens provides good picture quality. Such Smartphones are equipped with advanced computing capability and connectivity. Mobile Apps of smart phone also makes life easy and enjoying. Thousands of mobile phones apps are being developed daily and daily to make life calm and excellence of life. But no mobile app has been developed to store marks of a student and to calculate it automatically for CGPA and/or Percentage and also to store some minor data of a person required for some calculation.

This paper incorporates such day to day problem; design solution to them by developing an application for smart Phones. This App has the feature of password protection and the password can be retrieved through email ID, if one forgets. User of the App is provided the option of sending the calculated result or any Text message through e-mail upon clicking a single button. These text and result can also be shared instantly to everyone on any social networking sites if required, again on a single click of button. App removes the burden of cramming the marks in user’s head and hence providing easiness to its users. Windows Azure as a cloud computing platform is used for application and data storage purpose[18].

II. BACKGROUND

A mobile app is a software application designed to run on smartphones, tablet computers and other mobile devices. They are usually available through application distribution platforms, which are typically operated by the owner of the mobile operating system, such as the Apple App Store, Google Play, Windows Phone Store, and BlackBerry App World. They are downloaded from the platform to a target device, such as an iPhone, BlackBerry, Android phone or Windows Phone. Mobile apps were originally offered for general productivity and information retrieval, including email, calendar, contacts, and stock market and weather information. However, public demand and the availability of developer tools drove rapid expansion into other categories, such as mobile games, factory automation, GPS and location-based services, banking, order-tracking, and ticket purchases. The

explosion in number and variety of apps made discovery a challenge, which in turn led to the creation of a wide range of review, recommendation, and sources, including blogs, magazines, and dedicated online app-discovery services. But even new applications are required to solve the other daily problem such as this Recorder App. The feature of this App is different and such feature and quality in other application is not available in the market.

Windows Azure used for this app is a cloud computing platform and infrastructure, created by Microsoft [17]. Cloud Computing is intended to serve as a means of connecting users worldwide without having any installation of application and maintaining of files. Cloud services include deployment of applications and maintaining database at remote servers. Cloud Computing is a realization of virtual lab. Cloud computing offers an attractive solution to customers keen to acquire computing infrastructure without large up-front investment.

III. TOOLS, SERVICE AND METHOD This section is to present a detailed description of the Result Recorder app. It explain the hardware and software requirements for developing the application and its interface, tested features of the app, what the app will do, the constraints under which it must operate and how the app react to external stimuli. A. Hardware Platform This app has been developed using 4 GB of RAM, P-IV Core to Duo 2.20 GHz 250 GB Hard disk space but the Minimum requirement of such kind of application for a machine is:

• 1.6 GHz or faster processor • 1 GB of RAM (1.5 GB if running on a virtual

machine) • 10 GB (NTFS) of available hard disk space

5400 RPM hard drive • DirectX 9-capable video card running at 1024 x 768

or higher display resolution B. Software Platform This app is developed in a platform of Microsoft windows 8 Operating System. Microsoft Windows is a series of graphical interface operating systems designed, developed, marketed, and sold by Microsoft onwards from November 20, 1985. The

most recent versions of Windows are windows 8 and 8.1.The Other Supported Operating systems are :

• Windows 7 SP1 (x86 and x64) • Windows 8 (x86 and x64) • Windows Server 2008 R2 (x64) • Windows Server 2012 (x64)

C. Development tools and Storage Visual Studio ultimate 2012 and window Azure have been used as a tool to develop this Recorder Apps for Designing and Development of a Smart Phone Application. Visual Studio Ultimate 2012 and 2013 is the state-of-the-art development solution that empowers teams of all sizes to design and create compelling apps to delight users. One can create innovative, high-quality solutions and at reduced cost of development. Windows Azure is a cloud computing platform and infrastructure, created by Microsoft, for building, deploying and managing applications and services through a global network of Microsoft-managed datacenters [17]. It has been used as platform as a service (PaaS) and infrastructure as a service (IaaS) services. D. Functionalities The user of this apps enters, edit and store marks, gets it processed and result is displayed back in the form of CGPA and Percentage. The Result can be emailed; SMSed or it can be shared with any one on any social website.

Fig. 3 : Functionalities by User

The result recorder app have only one user- who is final user, he/she accesses all the functionalities viz- Password option, Store, edit, View marks, email and SMS the records. E. Emulation and Test-bad A Test bed is created for this recorder application via Windows phone emulator in order to provide a virtualized environment.

Windows Phone Emulator is a desktop application that emulates a Windows Phone device. It provides a virtualized environment in which one can debug and test Windows Phone apps without a physical device. It also provides an isolated environment for any application prototypes. Windows Phone 8 Emulator requires Visual Studio 2012; it is not backward compatible with earlier versions of Visual Studio.

IV. RESULT ANALYSIS The user of this apps enters, edit and store marks, gets it processed and result is displayed in the form of CGPA and Percentage. Once entered the App removes the burden of cramming the marks in user’s head as it is stored permanently. Input Format is changed according to requirement.

Fig. 5: Input Format Screen The desired result is displayed one at a time or both. The result can also be shown in the form of a table or Text. It is password protected and password can be change as and when required. The Result can be emailed; SMSed or it can be shared with any one on any social website on a single click of a button.

The proper functioning of this recorder apps not only tested and emulated on windows phone emulator but the application is also got installed on different windows smart phone and result is upto the mark.

V. SECURITIES AND ISSUES Windows Azure is a cloud computing platform to store the date which is itself is safe and there is no issue of security as Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources such as networks, servers, storage, applications, and services that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model is composed of five essential characteristics, three service models, and four deployment models. Security issues depend on types of service and Deployment Models. For IaaS, vendor responsibility is around physical, environmental and virtualization security. Almost all Cloud providers use virtualization to provide economies of scale and optimal distributed architecture. Virtualization has its own set of security issues. Windows Azure is a cloud computing platform and infrastructure, created by Microsoft, for building, deploying and managing applications and services through a global network of Microsoft-managed datacenters so it is understood fully secure models. Even the data stored on cloud is not so much of use for anyone except user so security is concerned with the cloud itself that is very highly secure and reliable.

VI. CONCLUSION AND FUTURE SCOPE This app is very useful as and when one is required to convey his/her marks instantly in the form of CGPA and Percentage. One can argue to take picture of mark sheets in his/her smart phone for the same purpose, but the app is able to do other thing also which are as under: 1. App will calculate Percentage/CGPA automatically and show it in a result page. 2. App has the feature of password protection and the password can be retrieved on email ID, if forgotten.

3. User has the option of sending the result through Email or Text message on a single click of the button. 4. of course, if one score really good then he/she can showcase his/her marks to social networking sites on a single click of button. Recorder app displays the result as required but it can be enriched by developing the other such apps according to considering other different ideas such as creating a list of item to be purchased monthly and storing them in Smart phones. When one goes for shopping in a retail confectioner store, he/she can use that list of item while buying the item without need to memorize it. Such list would also help in future purchasing also as not only that list would be available to him/her but it price can also be saved using app in smart phones. A budget can also be maintained accordingly before going to the market. Even this recorder App is extendable and enhance-able by adding the following feature within it in near future. • Auto complete box will be added in place of normal text

boxes which will make the work of storing the marks easier for user.

• Leader board (like we have in games) will be added which will allow user to make the group of his class, sent the invitation to the friends and which will compare results of the students of the class.

• Backup functionality will be given which will allow the user to make backup of the database of the marks at the cloud.

• Maximum marks field, passing marks field and maximum grace marks field will be given in settings page. If user fill the value in Maximum marks field at settings page, we can automatically fill the maximum marks fields while storing the marks. Value of minimum passing marks will allow app to highlight the marks at view result page in which user has the backlog.
