Custom Mobile App Development Services

We provide mobile application development services for smartphones and tablets on iOS and Android. Our mobile applications can have functionality of any complexity and support various technologies and communication protocols. Our team carries out a full Android and iOS mobile app development cycle, from determining the project's scope to launching the software and carrying out warranty service.

What we do

As a native and cross-platform mobile app development company, Integra finds its advantages in both mobile software types. We create user-friendly applications for Apple smartphones and tablets using Swift and Objective-C. Our experts build software products for all Android mobile devices using Java. Native application development provides a higher level of security. By using native languages, developers can create more optimized and performant programs. We offer cross-platform mobile application development services and create software solutions that can run on multiple operating systems. We use the Qt framework and its rich tools to develop cross-platform mobile applications in C++.

Cross-Platform App Development

Being a mobile app development agency with years of experience, we can create cross-platform solutions for multiple operating systems. Cross-platform apps built on the same code base have similar interfaces and functionality on all platforms, which is very convenient for users. Cross-platform development is faster and cheaper than creating native applications for each OS. We use C++, QML, and Qt to build custom cross-platform solutions.

Testing and Launch

Testing occurs at all stages of software development. Our app developer agency checks cross-platform applications on target devices to eliminate shortcomings and errors in functionality and adjust the design. We also prepare the necessary software documentation and can release the app to the App Store, Google Play, and other app stores and distribution platforms.

We get acquainted with the concept of the future solution and sign a non-disclosure agreement. The team gathers project requirements, studies relevant documents, and analyzes rival products on the market. At this phase, a preliminary project evaluation is made.

2

We contact the customer to confirm the project requirements. Then we create a technical specification and set a budget and deadlines.

3

We make the final evaluation of the project, make up a team, and schedule its workload.

4

We sign a contract for mobile app development. The team gets to work.

5

We select libraries, languages, and tools and get into software development. The team identifies and eliminates bugs and optimizes the performance of the software. Customers receive daily reports on the progress. If necessary, the plan can be amended.

6

The team tests all the software functions. We check its performance under corresponding operating conditions and run some tests required for product certification. If necessary, the product is then modified.

7

After the tests, we finalize the necessary documentation. We can prepare manuals if the product is designed for in-house use.

8

When the development process is finished, customers can enjoy a free warranty period. During this time, the team will fix any bugs and defects in the product.

Frequently Asked Questions

Read this information to better understand our custom mobile app development services.

How long does it take to create a mobile application?

The timing of a project largely depends on its specifics, complexity, scale, choice of components, and logistics. For example, a project audit can take 1-2 months, while AI-based software development usually lasts much longer. We always set realistic deadlines when preparing the spec and stick to the schedule at all project stages.

Do you test applications before handing them over to customers?

Certainly! When creating mobile applications, testing and debugging are mandatory steps. Strictly speaking, we test software products throughout the entire development process and, finally, before handing them over to customers. After the project is finished, we provide a warranty period during which we fix any discovered bugs.

Can I order your services if I don’t have a clear plan?

Naturally! Our team of qualified analysts will help you shape ideas into a concept, estimate the costs, pick the most suitable technologies, and work out an action plan and a project specification.

What do I get after the project is finished?

Once your iOS or Android mobile app development is complete, you will receive a fully functional product, source code, technical documentation, and manuals. If necessary, we will also provide training.

What is a cross-platform application?

Cross-platform development allows you to write source code that can be compiled for different operating systems with minimal changes. Programmers don't have to rewrite much of the source code for each app version. They only need to tailor the app-building process for a specific OS. Such programs will work equally well on iOS and Android. Cross-platform development is faster and cheaper than creating native applications for each operating system.

What programming languages do you use?

Our experts are skilled in several languages used for mobile app development, including C++, QML, Swift, Objective-C, and Java. The choice depends on the operating system and mobile app functionality.

What technologies do you use for custom mobile application development?

We use Xcode and Android Studio for native mobile app development and the Qt framework for cross-platform development.

What to consider when hiring a mobile application development company?

When choosing a mobile app development company, the key things to take into account are the team's domain expertise and their experience in projects similar to yours. The outsourcing software development company must provide clear cost and schedule estimates and justify them in detail. You can check out previous customer reviews and company ratings on Clutch and similar platforms. Also, consider the team's communication skills to always be aware of how the work progresses.

What about intellectual property rights?

The cession of intellectual property rights is legislated in our contracts. We also sign a non-disclosure agreement to protect any sensitive information. We will mention your project on our website and other platforms only with your permission.

Can you guarantee the quality of the product?

We pay great attention to the quality of our work. The customer receives fully functional software and a detailed user manual. After finishing the project, we provide a free warranty period, during which the team will eliminate any discovered bugs. During the post-warranty period, we can also provide advice on possible modernization and modification of your product.
