Process We Follow to Develop a Feature-Rich Mobile App

phase 1


Turn your app idea from concept to MVP

phase 2


Sketch out the app to meet user needs

phase 3


Transform the designs into an actual mobile application

Phase 1. Design

Our mobile app design incorporates both user experience (UX) and user interface (UI). From color scheme to font selection to the types of widgets and buttons, we cover it all.

Design Discovery

Our professionals start the designing process by identifying the project's objective and scope to deliver exceptional results.

Start with a Team Discussion

In the beginning, we will have a regular phone call or meeting to discover what precisely your demands are. In this, we want the essential details from your side, including what sort of app you aspire to develop, who is your target audience, when do you want it, what your budget is, and more.

User Personas

Here, we'll build a list of user personas based on our research to describe the different types of potential users that might use your products and services.

User Experience Design

With our proven UX design process, we make sure that users' needs are resolved, and the interface of the app remains effortless and smooth.

Feature Map

To begin, we create a feature map, a high-level illustration of the application's features.

User Flow

Then comes the user flow to show the actions customers will take to accomplish particular purposes.


Finally, we create wireframes of the app's initial views that give the overall design of the screen.

User Interface Design

In this step, we move to developing interfaces in the app, concentrating on looks or style.

Prototype & Estimation

After completing high-fidelity designs, we upload them to Figma or Adobe XD to build a clickable prototype.

Phase 2. Development

We pursue an iterative development methodology where we make constant modifications as far as the programming is involved until and unless we see the expected outcomes. From iOS to Android, we can do it all.


Pre-Development Planning

Our experts perform pre-development planning to properly prepare and guarantee a smooth, productive, and dynamic development process. This includes gathering the programmers, concluding a design to development handoff, setting project milestones, planning sprints, and building stories.

Team Gathering

Our development team comprises experts having years of experience in building applications for different business domains. We formulate a team that involves a project manager, senior developers, quality analysts, designers, and business analysts.

Design to Dev Handoff

As soon as the development team is gathered, they get introduced to the original design unit for design to dev handoff connection. A complete handoff guarantees that programmers know the app entirely and have everything required to create it.

Before the development phase, we make sure that the design team meets the coders and evaluates everything built during the design phases. It includes the market research report, user stories, user personas, user flow map, high fidelity designs, style guide, and clickable prototype.

Set Milestones

In this step, our project manager sets the core milestones for your project, known as version launches. We believe that several version releases would help you to get the desired results. Each version consists of limited app editions with some functional features to test.

Formulate Stories

After the establishment of milestones, the project manager starts building stories. Stories appear like tickets, which are allotted to app developers throughout sprints. They explain what the developer requires to make and incorporate approval standards, which shows how the feature should do for it to be affirmed by QA.

Sprint Planning

All the stories created in the former step bucketed into two-week sprints. Our professionals try to draw out as many sprints as viable at the commencement of the project. Nevertheless, the first two sprints are outlined in detail and are more precise than sprints prepared later in the development timelines.

Active Development

As soon as the pre-development preparation is done, we don't waste time and jump to active development. This involves performing two-week sprints, managing retrospectives after each sprint, and releasing editions based on the planned project milestones.

Sprint Execution Begins

In this step, developers are allotted several stories for every two-week sprint. Every story is assigned a predicted time (hours) to complete, and the connected expected hours match the number of hours present in the sprint. Besides, every story incorporates a summary of what to develop, links to needed assets like icons and components, and an approval system.

Test Coverage

As soon as developers complete the stories, they develop integration tests and automated unit tests into the code. It is a crucial step since it notifies programmers when something cracks as new code is proposed. Without test coverage, every time a new code is introduced, the whole app will require to be manually examined to see if the current code broke the old one. This is costly, ineffective, and time-consuming.

A few programmers skip testing quickly to go fast and save time. However, this can become costly in the long run. We build our app by performing end-to-end testing.

Unit Testing

Unit Testing separates a part of code and validates its accuracy. A Unit, perhaps, is a single function, process, methodology, object, or module.

Integration Testing

Integration testing is a kind of testing that connects single unit tests and tests them as a collection. The objective of this is to find errors in the communications between integrated units.

Continuous Integration

Continuous integration testing needs developers to combine their code to a distributed code repository numerous times each day. It can be tested with an automated development method and an automated test suite.

Quality Assurance

Once the app developers finish a story and create unit and integration tests, it is available for examination by Quality Assurance. If the story clears QA, it is then transferred to the Project Manager. If it fails Quality Assurance, it's pushed back to the programmer for revision. QA checks for several factors, including:

  • Does the code match the acceptance standards described in the story?
  • Does the UI (User Interface) meet the designs?
  • Is the code working accurately on various kinds of devices and browsers?
  • Is it mobile-friendly across several form factors?

Code Review & Merge to Master

As the story passes Quality Assurance, it's forwarded to the project manager to evaluate the original code to sustain a high code quality stage and assess the code/feature for the last time. If all the things seem good, the PM connects the code to the master to complete the story. Our code quality is judged against the code quality guidelines. At Apparrant, we write easy and clean code.


One of the simplest methods to keep code understandable and clean is to be brief. Our experts know that less code indicates less complexity, less code to manage, and fewer chances for bugs. Hence, we keep it short and easy.

Obvious to Other Programmers

It is possible to read code in plain English. Records should be well-managed as per the best traditions of each language or framework. Classes, filenames, variables, functions or methods, and parameters should be mentioned clearly and with intent and context in mind.

Linting or Code Formatting

Code should be operated with an automated linter. Suppose your project is not deployed to run automatically with git hooks or CI; you need to establish that up as quickly as possible.


Drafting clean code at the initial time is quite challenging. Before committing (and once you have composed your tests to include the functionality you just finished), you should consume your time in refactoring your code.

Self Documenting

Comments are restrained when you can't accurately communicate the intent and working of a class or method with description and clean code. You would see that this should be a pretty unusual circumstance. You can nearly always refactor and utilize considered naming to communicate sufficient intent and context to your code.

Test Coverage

Code should have a programmed test suite to green before joining a branch to understand. If your project doesn't have one, you need to set this up as early as possible. It is crucial to have e2e, unit tests, and integration and get a 95% scope level for every project.

Sprint Retrospective

Everything that impacts how the Scrum team develops a product, like the processes, practices, tools, and interactions, is evaluated. Product owner, development team, scrum master, and stakeholders attend the retrospective.

Based on the discussions, the team members work on the modifications and then move to the upcoming Sprint with an enhanced process. One of the best things regarding a retrospective is that it appears when the Sprint ends. This lets the fresh ideas make their place and positively change the team and project.

Version Releases

Versioning is a crucial element of your mobile app upgrade and maintenance approach. As sprints are made, they appear as version releases that comprise a restricted number of performed features set for User Acceptance Testing.


Finally, all of the version/edition releases have been concluded and affirmed by the client. The mobile app is set for beta testing, and ultimately, a public (or internal) launch.

Once the public release is done, the app goes to either continued development or maintenance mode.

Phase 3. Maintain

We don't stop after launching the app. After it goes live, we provide ongoing support through a maintenance contract and/or running development agreements.

Bug Reporting & Error Monitoring

We utilize numerous third-party innovations for error examination and bug reporting like bugsnag, Sentry, CodeClimate, and more. These tools inform us when anything goes wrong and assist in optimizing the performance.

Performance Optimization

For apps that handle large volumes of data or have humongous users, continuous performance optimization is needed. This can involve monitoring & optimizing servers, crash response and reporting, load testing and optimization, and more.

Update Editions

The open-source community constantly updates open-source programming languages. Every update is known as a "version." It's essential to keep editions updated to guarantee performance, protection, etc. Hence, our maintenance agreements cover updating versions as a regular deliverable.

Update Integrations & Dependencies

Modern apps are developed with several third-party APIs and dependencies. Nevertheless, these APIs and dependencies can vary over time. So a vital component of our maintenance contracts is updating apps to assure they stay integrated accurately with third-party provinces.

Ongoing Development

For customers who wish to introduce features and make adjustments timely, an ongoing development contract will be required, along with a maintenance agreement. This is what ongoing development agreements involve:

Product Roadmaps

We'll operate with your team to build a strong product roadmap that describes which distinct features will be made and when. This aids in prioritizing features, plan funds, etc.

Design New Features

Once the new features are introduced to the product roadmap, our professionals perform a short design method to show the new feature and its function within the current app.

Build New Features

As soon as the design is done, we'll determine the amount of time needed to build the feature. Following this, we will add it to an imminent sprint to be performed.
