The 5 Phases of the Mobile Application Development Process in Agency Work

Once your UI/UX design is complete, the next step should be creating a dynamic prototype. This mockup of your app can help test its functionality while gathering feedback from stakeholders.

Developers begin programming the app’s front end at this stage. They have two options for developing apps: platform development allows them to write code once and deploy across both iOS and Android, or native development which provides greater efficiency and offers superior user experiences.

The design phase is where your app starts to take form, beginning with defining functional requirements and developing a product roadmap – including identifying a minimum viable product (MVP) for first launch. Next, team members focus on its user interface (UI) and user experience design (UX), whether this means creating sketches on paper or digitally via wireframes and style guides – documents which record visual structure such as fonts, colors and graphics of an application’s user interface; in this stage it’s also essential to think through back-end systems like databases or servers which support its front-end functionality; lastly encryption standards must also be considered at this stage.

Once the design of your app is complete, the next step should be writing its code. This process depends on which platform you have selected – Apple devices come preloaded with native apps while Android phones allow users to purchase more from Google Play Store. Your choice of platform will determine the programming language and IDE you use – iOS developers must be knowledgeable of Swift/Objective-C for iOS while Android developers can utilize Java programming alongside Android Studio as an IDE.

Step one is essential to the success of any mobile application: meeting user quality and performance expectations. For instance, your app should run efficiently on devices running it while remaining user-friendly about navigation and understanding.

When developing an app, an agency conducts thorough testing to make sure it works as intended. Furthermore, mobile apps require routine maintenance to remain up-to-date with operating system changes, review guidelines, and performance standards.

Once the app has been tested and proven its worthiness, its release to the public is key for gathering feedback and collecting user data on usage patterns and engagement rates. At this stage, updates to features or improvements may need to be introduced in response to feedback received, while tracking engagement metrics is also an integral component.


At this phase, mobile app development teams establish a project roadmap. Requirements are assessed and prioritized; features essential to app functionality are listed; this step is particularly critical for apps used by employees who may have different priorities and expectations of what an app should do. Once this phase has concluded, a Minimum Viable Product (MVP) is defined and created – an app with only essential functions so it can be released risk-free while giving teams enough data to evaluate how users respond to this new mobile tool.

At this phase, a mobile app development agency will also determine which technology stack will be utilized in its creation. For instance, if the application will target iOS and Android devices specifically, developers with experience using these platforms should be on board; otherwise, if using Titanium or Xamarin frameworks for development then developers familiar with those technologies should also be present on board.

At this stage, app UI and UX design is also created, paying special attention to user experience. The goal is to craft an intuitive visual structure while still adhering to client branding and business goals. Wireframes may also be created at this point before following a style guide for mockups of how the finished app will appear.

Once the UI and UX design is complete, development takes the next step in its life cycle. This stage includes building backend and frontend systems for an app; typically these consist of databases and server-side objects responsible for its performance; during this step the developer selects programming languages, database engines and hosting environments before ultimately creating an app store to market the final product.


Testing comprises several activities designed to ensure an app satisfies user expectations, operates correctly and functions without error. Testing should also include maintenance updates to accommodate operating system changes and ensure an impressive app that builds trust among its users. Thorough testing and quality assurance (QA) provide users with confidence-inducing apps.

First and foremost in any app project is to identify its requirements, which includes its target audience, goals, and objectives as well as any potential challenges like cross-platform compatibility and data access. This phase should never be neglected or skipped over.

Next, a prototype or wireframe of the app must be constructed. This prototype must correspond with brand identity and user experience requirements, with user testing becoming essential in identifying issues as well as providing feedback at this stage.

At this stage, front-end developers transform pre-launch visions and UX or UI designs into functional code. Additionally, they build databases and establish infrastructures for backend functionality. It is crucial that when developing mobile apps using either web technologies or native languages that the appropriate programming language be selected based on whether the app will run on specific mobile platforms.

As new devices and operating systems enter the market every year, it is vital that apps remain compatible with current hardware and software. That is why QA teams test applications on various platforms and devices to ensure the app runs flawlessly across them all.

A great QA team should be able to detect errors, bugs and glitches within an app to quickly address them and improve its performance and usability. They should also make sure it complies with industry or regulatory standards while conducting regression tests regularly when any changes are made to its source code – saving both time and resources over time.


Imagine watching an action-packed movie when suddenly, its screen went blank – this would certainly cause irritation! App users expect seamless mobile experiences that won’t cause them to uninstall an application, which makes ongoing maintenance and updates so important.

Adaptive maintenance refers to making modifications to an app in order to keep it functional and usable in an ever-evolving environment. Such modifications might involve updating to ensure compatibility with new devices or operating systems or adding features for increased functionality. It’s an effective way of avoiding future complications as well as remaining up-to-date with modern technologies, increasing user satisfaction and app retention rates significantly.

Integration is an integral component of mobile application development, and can involve linking the app with various business systems and services – such as payment gateways, customer relationship management (CRM) systems or social media platforms – depending on its complexity. Integration may also encompass backend server systems or databases.

Another significant part of maintenance involves updating the app’s UI and UX. This involves making necessary changes to stay current with market trends and user preferences, while simultaneously updating style and design elements accordingly.

Finally, your app must be updated to comply with any regulations set by app stores. Apple App Store frequently revises its policies, and apps published there must adhere to them if they want to remain compliant on its platform. App developers bear full responsibility for making necessary updates so as to maintain compliant mobile applications.

App developers used to be forced to develop separate versions of their apps for different operating systems, which was both time-consuming and costly. But modern cross-platform tools make it possible to use a single code base when developing Apple iOS, Android or progressive web apps (PWAs) compatible with all devices. Furthermore, hardware manufacturers regularly release new models that require apps be updated in order to remain compatible.
