Mobile App Development Lifecycle

The application development lifecycle of a mobile app is as follows.

The product owner will specify the objectives(requirements) of the mobile app. The Business analyst will convert the requirements into specifications. The UI/UX designer develops a wireframe for the flow of screens in the mobile app. The graphic designer will create the graphical assets as needed. The app developers or programmers develop the app as per the specifications. The QA team tests the integrity and the functionality of the app. And it goes live on App Store and/or Google Play. These stages are further explained below.

1.   Requirements Gathering

Clients specify their objectives/requirements of a given app by listing out as bullet points or in a spreadsheet. Even though there can be several varieties of requirements, the app to be made can be of any of the following three important kinds.

1.   An app to be made from the scratch building all the screens with the required features in each screen, integrating with backend if needed, implement the persistent storage etc.

2.   An app to be crated as a clone to an existing website or app running on another platform

3.   An app is already existing but new features to be added or enhanced.

2.   Wireframe of the app

The content of the screens of the app once decided, can be captured into a wireframe which is a visual illustration of the appearance and flow of screens in an app. Various graphic designing tools are used to prepare this wireframe. This wireframe once made will act as a perfect tool for clients to verify the requirements being met with the proposed solutions and for the developers to understand what to be built inside the app screens. 

3. Design and Development of the app

Each screen in the wireframe is taken by the graphic designer and he prepares the graphical assets(images, textures, animations) etc. These assets are made as sets of various resolutions so as to match to the fragmentation of the devices. Once the assets are provided, the developers code the app in the prescribed programming language and implement the business logic of the app thus meeting all the requirements specified by the clients and depicted in the wireframe.

4. QA & Deployment

The developed app the then rigorously tested for any bugs or crashes or freezes etc. This will ensure the integrity of the app and its usability on various devices with variety of resolutions and versions of OS.

At the end, the app is submitted to the app store/google play for release to app users.

Native Mobile Apps Vs Hybrid Mobile Apps

The mobile app industry is thriving on two paths of app development, that are native and hybrid. Simply put, native is the choice of application developers and hybrid is the choice of web developers.Both have their own advantages but in the long run, native offers better user experience, reliability and maintainability over apps that are made in hybrid.

What are native mobile apps?

The smartphones work with an operating system, just like computers(PCs) work with operating systems like Windows, Linux etc. The common operating systems for smartphones and tablets are Google’s Android and Apple’s iOS. These operating systems are pre-installed in a smartphone by the OEM(Original Equipment Manufacturer). So when a new smartphone is unboxed and switched on for the first time, it will have OS installed in it and few pre-installed apps like Contacts, Phone, Messaging, Jukebox, Gallery etc. All these apps which are installed on operating system and work on the layers or software stack of the OS are called native apps. They will have an executable file on the OS running when they are active. Just like a exe file in Windows. An app that is developed for native execution, preferably using the SDK and language prescribed by the OEM(Apple or Google) will be the most powerful and hassle-free and easy to migrate between various OS versions.

What are Hybrid mobile apps?

Hybrid mobile apps are web pages in the form of an app. Web technologies like html,jQuery,css etc. are used to create the content for an app and then exported as an installer so that it installs on the phone’s OS and appear like a native app. The User interface of the hybrid apps will not have the User interface elements of the native SDKs resulting in poor user experience. Also they will have limited functionality in using the underlying hardware thus making this method of development not suitable for high-end apps which needs R & D and enterprise apps which need high levels of user satisfaction.

For Business enterprises, Website or Mobile app or Both?

In the recent years,The smartphones and tablets sold,outnumbered the sales of PCs and laptops indicating the shift of consumption of internet in the years to come. Especially, millennials who are the biggest users of web rely on their gadgets to execute their daily routine. This essentially emphasises the need of reaching them with a mobile app than a website as the website on a mobile browser is far lesser powerful than a mobile app. The user experience too greater in a mobile app. Most importantly the mobile app can take the advantage of the high specifications of the device and offer a better, smoother, simpler solution to any task at hand. Last but not the least a mobile app can quickly integrate into any new features like finger print sensor, connected cars, home automation, contact less payments etc. 

Businesses for whom customer support is at the forefront, rely on websites to give information, receive feedback and attend to any complaints etc. But the browsing of a website can be cumbersome and limiting when the content is viewed in a mobile screen with lesser resolution due to screen size. Also entering a data in a website is difficult on a smartphone where the physical keyboard is replaced by the soft keypad. The typing will mostly happen with a single hand on a smartphone, if he is travelling or eating etc. Thus a mobile app offers much better user experience if the same content is presented as a mobile app than a web site. 

Listed below are the advantages and disadvantages of the mobile apps.

Mobile Apps - Advantages

1.   Apps run on OS directly and can have all the features supported by the under lying OS.

2.   Apps can integrate with 3rd party SDKs thus extending the power of the app is easy.

3.   Apps can have secure persistent storage and hence will be best for data protection.

4.   Apps can update themselves automatically.

5.   Apps help in retention of the customers for businesses.

Mobile Apps - Disadvantages

1.   They have to be downloaded and installed first to use.

2.   They consume some space on the device hard drive depending on their size of installer package.

Web sites - Advantages

1.   Users don't need to download the app, just open the URL in a browser.

2.   Generally are light weight saving data charges for the user.

3.   Are browser dependant and hence auto adjust to various resolutions.

Web sites - Disadvantages

1.   More suitable for desktops and laptops than smartphones and tablets due to farm factor of the devices.

2.   Conventionally rely on older techniques of user interaction like keyboard and mouse rather than the much sophisticated touch-screen displays.

3.   Use the user-interface controls like check boxes and list boxes which are the legacy of desktop programming.

4.   keeping persistent storage secure can be a challenge. 

5.   Many of the features which are developed by third parties and released as a 3rd party SDKs can’t be integrated as they support only apps, but not websites.

Hence it is highly recommended for enterprises and businesses to have both the website and mobile app to reach, acquire and retain their customers.
