Development of a Mobile Application for Construction. Creating a Mobile Application for the Construction Industry for iOS and Android
A client from the construction industry approached us with a request to develop a mobile application that would simplify project management processes and interaction between participants in construction processes. The task was to create a cross-platform solution for iOS and Android, with real-time data synchronization and integration with internal accounting systems.
Client
Our client is a large construction company founded in 2000. The company specializes in providing a full range of construction services: from design and construction of residential complexes to repair and finishing of premises. Their operations cover the entire country, including both major cities and regional facilities.
At the time of contacting our agency, the company had already successfully completed over 50 projects. Today, their portfolio includes more than 80 completed projects. This year, the company focused on developing digital technologies to simplify customer interaction and optimize internal processes.
We took on the task of creating a mobile application that would become a convenient tool for clients and partners, as well as help the company strengthen its position in the construction services market.
Task
Develop a mobile application for smartphones on iOS and Android platforms with a minimal set of features (MVP). The project is aimed at new and existing clients of the construction company, as well as partners involved in project implementation.
In the application, the user can:
-
Track the status of construction projects: see the current progress of ongoing projects, including construction stages and completion deadlines.
-
Receive notifications: promptly learn about important changes, such as deadline shifts or stage completions.
-
Submit requests and feedback: send questions or suggestions regarding projects, and attach photos for clarity.
-
View interaction history: see all requests, feedback, and responses from the company in one section.
-
Scan QR codes on sites: get detailed information about specific construction stages, materials used, and responsible personnel.
-
See current promotions and special offers: stay updated on current discounts for construction materials or company services.
-
Monitor orders: track the status of material or equipment orders, including delivery and processing stages.
We focused on creating a convenient and functional tool that would simplify the interaction of clients and partners with the company, as well as increase trust and transparency in operations.

How Things Worked Before
Before the introduction of the mobile application, clients of the construction company faced several inconveniences that slowed down the interaction process and reduced satisfaction levels.
-
Tracking project progress: Clients could only learn about the current state of construction through calls to managers or personal visits to the site. This was time-consuming and did not always provide up-to-date information.
-
Receiving documents and reports: All documents, including estimates, work schedules, and reports, were provided in paper form or via email, creating confusion and making it difficult to find the necessary information.
-
Questions and requests: To ask a question or clarify details, clients had to call managers or write emails, which often led to delays in responses.
-
Order tracking: Tracking the status of material or equipment orders required constant follow-ups with company employees, as there was no unified system for this.
-
Promotions and special offers: Information about current discounts or promotions was only available through promotional materials distributed at the company’s office or on-site.
This system was inefficient and did not meet modern service standards. We proposed a solution that not only simplified client interaction with the company but also made it more transparent and convenient.
What Was Unsatisfactory
Before the introduction of the mobile application, clients of the construction company faced several issues that negatively impacted their experience:
-
Lack of up-to-date information: Clients could not promptly learn about the current state of construction or changes in the work schedule. This led to misunderstandings and dissatisfaction.
-
Difficulty with calculations: Clients could not independently estimate the cost of construction stages or calculate discounts. They had to contact managers, which took time.
-
Dependence on paper documents: All contracts, estimates, and reports were provided in paper form or via email, creating confusion and making it difficult to access information.
-
Lack of mobility: Clients had to call or email to ask questions or clarify details. This slowed down the communication process.
-
Inaccessibility of promotions and special offers: Information about current discounts or promotions was only available through promotional materials, which were not always at hand.
-
Lack of transparency: Clients could not independently track the status of material or equipment orders, which caused distrust.
These issues not only worsened the client experience but also created additional workload for the company’s employees.
Solution
We analyzed existing mobile applications in the construction industry and found that most of them did not address key client needs. Many applications were created more for the sake of appearance than for actual service improvement. This was evident from user reviews, which complained about inconvenience and the lack of useful features.
Our team decided to approach the task differently. We developed a mobile application that not only meets modern standards but also genuinely solves client problems. The application became a convenient tool for tracking project progress, receiving up-to-date information, calculating costs, and interacting with the company.
Resources
The project to develop a mobile application for the construction company was ambitious, but the budget required a balanced approach. We focused on creating a minimum viable product (MVP) that included only the most essential features. Each feature was carefully designed to provide maximum value to users.

Challenges We Faced and How We Overcame Them
Developing a mobile application for the construction industry is always a challenge, especially when it comes to synchronizing with existing systems and ensuring uninterrupted operation. One of the key difficulties was establishing effective communication between our team and the client’s team. This required clear communication, coordination, and understanding of business processes on both sides.
In addition, we faced the following tasks:
-
Integration of the application with existing accounting systems. We needed to ensure seamless data synchronization so that users could work in the application without delays or errors.
-
Working with the client database. We developed mechanisms for secure and convenient management of client data to ensure that information remained up-to-date and accessible.
-
Synchronization of passwords and authorization. For this, we implemented a unified authorization system that provides secure access to all related systems.
This project was not our first of its kind. We had previously encountered similar tasks when developing CRM solutions. The experience gained allowed us to prepare in advance for potential challenges. We developed a universal API that significantly simplified the integration and data synchronization process. This solution not only accelerated development but also increased the application’s reliability.

Mobile Application Prototype
Stages of Project Work
1. Scenario Development and Prototype Creation
The first stage of any project is a deep dive into the client’s tasks and the creation of a prototype of the future application. At this stage, we made key decisions that determined the success of the entire project. Our goal was to develop not just an application but a truly useful tool for users, which would not become “dead weight,” as is often the case with other solutions.
One of the important tasks was adhering to a limited budget. We focused on retaining only those features that would be most useful for both the business and end-users.
To understand what was truly important for clients, we conducted over 30 interviews with the target audience. As a result, we found that users wanted to see up-to-date information about their orders, track project statuses, and receive notifications about important changes. Based on this data, we developed interaction scenarios that formed the basis of the application.
We also conducted several brainstorming sessions to optimize processes and reduce business costs. For example, we proposed eliminating unnecessary paperwork and automating some routine tasks, which saved resources.
After finalizing all scenarios and agreeing on them with the client, we moved on to creating the prototype.
2. Design Concept Creation
The client had a clearly defined brand book, including corporate colors, fonts, logos, and other brand elements. Our task was to adapt these elements for the mobile application while maintaining brand recognition.
We developed a design concept that not only adhered to the brand book but also considered the specifics of mobile interfaces. The priority was to create a simple, intuitive interface that would ensure ease of use.
An important aspect was working with colors. We carefully selected shades to ensure they not only matched the brand book but also served functional purposes. For example, colors were used to aid navigation within the application without distracting users from the content.
Throughout this stage, we closely collaborated with the client, discussing every decision. Any wishes or ideas were considered in terms of their practical value and impact on the user experience.
As a result, we created a functional, minimalist, and recognizable design that fully met the project’s objectives and the client’s expectations.
Programming
The architecture of the application’s server-side was developed based on our own scaffold, built on the principles of clean architecture. This approach ensures flexibility, scalability, and ease of system maintenance.
Key Principles of Clean Architecture:
-
Autonomy of logic, interaction interfaces, and data.
-
Independence from specific databases, external frameworks, and libraries.
-
Direction of dependencies from external layers to internal ones, using boundary interfaces (Boundaries).
This approach allows for expanding the application’s functionality without affecting the presentation and data layers. This significantly simplifies future modifications, improves system testability, and makes it easier to maintain.
At the start of the project, we already understood the system’s business logic and the data set that needed to be synchronized with accounting systems. However, the exact format and structure of the data were unknown. We anticipated the need for adjustments and changes in the API for synchronization, so the flexibility of the back-end architecture was critical for us.
Key Aspects of Development:
-
High availability and scalability.
We carefully analyzed potentially complex and high-load areas of the system, divided them, and moved them to separate services. This allowed us to ensure stable application performance even under high load.
-
Use of Docker.
Using Docker, we deployed an infrastructure that can be easily scaled. In case of increased load, any service can be quickly moved to another server or have its resources increased.
-
API separation.
We divided the API into two main parts:
-
API for data synchronization.
This service is responsible for data relevance and processing. We used REST API for interaction with accounting systems, allowing the application to connect to multiple data sources.
-
API for the mobile client.
This service ensures interaction with the mobile application, providing data in the format expected by the client.
This separation allowed us to:
-
Guarantee a unified data format for the mobile application.
-
Distribute system load by separating synchronization processes and user requests.
-
Ensure controlled data modifications.
As a result, we created a flexible and reliable server-side that easily adapts to changes and scales according to business needs.

Results of the Work
The mobile application we developed for the construction industry fully met the client’s expectations and received positive feedback from users. Here are the key results:
-
Functional and user-friendly design.
We created an application that not only adheres to the client’s corporate style but also ensures ease of use. The design is minimalist, intuitive, and recognizable to users.
-
Useful functionality without unnecessary load.
The application includes only the features that are truly necessary for users. We eliminated all unnecessary elements to make it as useful and convenient as possible.
