Mobile App Development

As of July 2022, the number of smartphone users in the world are 6.6 Billion, which translates to 83.72% of the world’s population owning a smartphone. In the year 2021, total download count of different apps totaled to 88.3 Billion. Users are moving to mobile devices and there is a significant portion of business waiting to be tapped.

App Development Agency

At Sunhim ecommerce, we cover all aspects of mobile app development, from requirements gathering all the way to app approvals and launch. We curate aesthetically appealing, easy to use, functional and cost effective mobile apps.

Mobile App Development Process

Business & Requirement Analysis

The 3 key questions to initiate the requirements analysis phase is asking the three questions:
Why? Why do we need the mobile app and what will it achieve
Who? who will be using the App and what solution do the user expect from the solution.
How? How will you meet user expectations and achieve desired results. What functionality are the users expecting


Wireframing is the process of building low-fidelity mockups that outline the structure and layouts of the pages, while conveying the information, direction and description of the user interface.
At Sunhim, we have a dedicated design team, to help with all your design needs, right from visioning & conceptualization, all the way to sharing aesthetically appealing protype design and ensuring approvals

Mockups and Prototypes

Mockups help showcase app design from a medium to high-fidelity point of view. Though mockups are visually close to final version, they are not interactive or navigable.
Whereas Prototypes, apart from being close to final version, also help focus on functionality and user interaction, of the application. A well executed prototyping has shown to save overall cost, due to minimal rework, and considerably elevate customer experience.

App Development

We call this the build phase, where actual development is accomplished. At Sunhim, we typically work on Agile methodology, where work is broken down into 2 week sprints.
What is more important, with Agile methodology, the client gets to review work demo in every sprint, to monitor progress and suggest changes

Q/A Testing

Planning for QA begins right from requirement analysis phase and culminates after the launch. This includes the QA plan, design and execution of the actual test. These are often followed by re-run of the test and regression testing. Often times customers and users teams are often embedded in the testing phase, which ensure higher quality deliverables.

Platform Approval

Each platform, weather iOS or Android, have their own app approval process and guidelines. The approval process has to be planned ahead and requires clear understanding of the platform needs. One thing to keep in mind is that, typically approval process takes time and you need to account ahead for it. Comprehensive testing is a must, particularly on security guidelines, to avoid rejections.


We typically categorize mobile apps in 3 broad categories

  • Native apps: These are build to work on a specific platform. The 2 most popular OS platforms are Apple iOS and Google Android.  Native Apps effectively use device specific hardware and software's, hence are typically optimized for performance and elevated user experience, not to mention being able to work offline. Since they are specific to platforms, it creates to need to build multiple versions of the code, to suit individual platforms, adding to time, effort and cost.
  • Web Apps: These are essentially responsive websites, that adapt to various mobile devices, that the users use. Unlike native apps, they don't have downloadable apps and since they use common code, the overall time, effort and cost is much less. That being said they typically lack in performance and user experience of a native app.
  • Hybrid Apps: To put it simply, to greater extent a web apps, but which contains lightweight native app container, that allows it to leverage some native platform features and aspects of hardware devices. It has a downloadable app, similar to a Native App, but build with front end technologies as JS, HTML5 and CSS, giving the cross-platform functionality. Due to cross platform functionality, Hybrid app cost is relatively less than a Native app, but often lacks in performance and user expereince,

Ionic and React Native are among the most common frameworks to develop Mobile apps, hence have a strong following and support for the frameworks.

Ionic has a greater emphasis on front end user experience. Since it allows developers to build once and run everywhere, it is relatively easy to learn. Its can also be easily integrated with other libraries and frameworks such as Angular, React etc. However as compared to React Native app, performance and security could be sometimes be found wanting. Often needing customization to address the gaps.


React  native: Often used to build cross-platform mobile application, for iOS, Android and Windows. React Native uses native components, as building blocks instead of Web components. It uses the features and capabilities of platform far better as compared to Ionic. As a result it performance is often found to be better. That being said, compared to Ionic, the learning curve for React Native is rather steep.

With people increasingly using mobile apps, the importance of mobile apps,  to business is growing with each passing day. Outlining key benefits to busines for building mobile apps

  • Brand building: Mobile apps offer companies the opportunity to build brand reinforcement through this new channel. What is more important, that can largely customize the customer experience, using their mobile application, which is typically limited in other channels
  • Increased visibility and direct marketing channel: Having your companies mobile application, in the customer's hand 24 x 7, exponentially increase the visibility, value and subsequent direct sale, with the end user.
  • Customer service and loyalty: An excellent platform to optimize customer experience. A mobile device is an excellent platform to provide consistent customer experience, which often is not guaranteed in retail business. Eventually adding to loyalty and retention with the customer.
  • Gain insights and boost sales: Getting to know customer behavior, patterns and feedback can be accomplished at a rapid pace, using mobile devices. This often help decision makers analyze the data sooner and make effective decisions in a timely manner, hence boosting overall sales.
