App Development for Startups

HQSoftware creates full-fledged software products for startups and ensures they are capable of providing excellent user experiences. As a startup app development company, we build expert solutions to assist any business in enhancing their productivity and profitability through business digitalization. We focus on delivering app development services that handle various business needs, regardless of the firm’s size or type.

Types of Mobile Apps We Develop

At HQSoftware, we leverage our competencies in creating mobile software for startups to produce effective applications that deliver exceptional client service. Within our app development services, we engineer a wide range of top-tier software, including native mobile apps, hybrid mobile apps, cross-platform mobile apps, and web apps.

Native Mobile Apps

Native apps are designed both for iOS and Android platforms, using the primary programming languages: Swift and Objective-C for iOS, and Java and Kotlin for Android. They can be accessed via any device using the appropriate platform.

Due to the numerous available APIs and tools offered by the iOS and Android platforms, native apps are scalable and have access to all of a platform’s native hardware and software features. 

Constant monitoring of OS upgrades and the ability to make changes provide online protection and security. The applications are hence far more productive, adaptable, and quick.

Native development gives a developer much more control over low-level system APIs.


  • access to low level APIs;
  • high performance and rich functionality;
  • effective operation with any devices running their OS;
  • easier launch to the market.

Hybrid Mobile Apps

Hybrid app development means that an app is developed using multiple languages and technologies and can function across platforms. The programming languages are: Kotlin, Swift and Javascript or Typescript.

Hybrid apps are integrated into the native application and allow access to particular hardware functions, such as the camera or calendar. They can access data on the user’s device and analyze them. Hybrid apps can operate through WebView, which allows other apps to launch websites. 

They function like and appear to be native apps. They can be installed on the device after being downloaded from the store. As these applications have access to the user’s data but frequently do not store their own data directly on the user’s device, the installation size can be kept to a minimum.


  • faster development;
  • easier post development support and updates;
  • high levels of customization;
  • may save money on development as there is no need to build two versions of the same product.

Cross-platform Mobile App

Cross-platform apps are developed with a language or framework suitable for a variety of mobile operating systems at once: Android, iOS, Windows, Linux, etc. Some of the frameworks are Flutter, React Native, Xamarin, etc.

The key benefit of cross-platform mobile app development is that a single code base can be used across many mobile platforms. A separate technical stack for each operating system is not required, so the engineering process is much faster and easier. As well, the same user interface and UX design are possible within all platforms for that reason.

Deploying an application on a different platform is simple thanks to code reuse. An application created on one platform will work on other platforms. 

Cross-platform apps can be used on a variety of devices without worrying about compatibility problems. The aim of creating  a cross-platform app is to reach a broader client base while reducing the time and expense of development.


  • fast development;
  • available for several different platforms at once;
  • one code is available for reuse on other platforms;
  • simple and quick deployment;
  • cost-effective cross-platform application development;
  • ability to use the same interface.

Mobile Web Apps

Mobile web apps are downloaded from the Internet and run in the web browser of the user’s device. They appear to be real applications, but they are actually customized websites that are not stored on the user’s device. The web application operates on a phone, tablet, laptop, or stationary PC device. The most popular programming languages are Javascript, Python, C++, Kotlin, and Rust.

Mobile Web apps may be used on numerous platforms, allow for faster loading, and can be automatically updated. They can be used via email clients, social networks, search engines, online stores, or online business programs. Web apps can be divided into 3 categories:

PWA (progressive web application) is in fact a native application inside the browser. It works everywhere and has a user-friendly interface, like a full-fledged application. PWA requires a HTTPS connection but can function partially without the Internet.

MPA (multi-page application) is an application that sends a request to the server and completely refreshes the page when an action is performed on it. A web page that simulates the operation of the application is also available in any browser. It does not run without the Internet, and it is not suitable for complex projects.

SPA (single-page application) is an HTML page that dynamically updates depending on user actions without a full reload. SPA technology is used for both responsive websites and PWA web applications.


  • access from different devices;
  • no need to download and install;
  • scalability;
  • operate the same in all browsers;
  • user data is stored in the cloud, which ensures their security.

Stages of Development

Every software development process has a number of stages where different tasks are carried out. Depending on the project methodology, specific activities should be used in each phase. Project planning, requirements analysis, design, development, testing, deployment, maintenance, and support are the seven fundamental phases that make up the software development life cycle, or SDLC.

  1. 1. Planning

    The planning phase assigns the major aspects of the further development process. This is one of the most important stages of the SDLC because it sets the course for the entire project. This stage includes creating project plans and choosing the methodology.

    A project manager focuses on defining project objects and goals, setting terms, identifying required resources (human resources, budget, software tools), and pointing out business benefits. The development team is formed in this first stage. 

  2. 2. Requirements Analysis

    The second phase begins with gathering project requirements, which is followed by a detailed analysis of customer requests and expectations. At this stage, architects and developers decide which development approach they will take and plan how to create a functional software application. 

    The outcome of the requirements analysis phase is a software requirements specification document (SRS), which should include all specifications (software, hardware, network, and security) for the upcoming project.

  3. 3. Design

    The next phase is design, which outlines stages and procurement requirements. At this stage, the development team uses the chosen programming language and design patterns to create a prototype of future software. On the design stage, you need to define the following:

    • The UI design: how the user will interact with the platform;
    • Programming: which approach will you take;
    • Communication: how the software will interact with other assets;
    • Platforms: on which platforms the software will be distributed.

  4. 4. Development

    The development phase involves writing code using a chosen programming language. To build the entire system, developers receive design documents, requirements specifications, and pattern code. Throughout this phase, the structure for the final prototype must be created.

    The code-development phase is not complete until testable, fully functional software is developed. Then comes additional work in the form of debugging and integrating various components before it can be run for testing.

  5. 5. Testing

    The next step in the SDLC is testing, where all the software requirements are tested to make sure that they are bug-free. The testing stage involves an iterative and multistage process to confirm that all errors are eliminated before release and that the software works correctly. It includes finding and fixing bugs and testing for security.

    QA engineers test all features of the application, make any necessary changes, and ensure that the software meets all specifications. 

  6. 6. Deployment

    The final phase is the deployment of the project’s product. It involves creating a plan for how to deploy the software, allocating resources correctly, meeting deadlines, tracking the project’s progress, and meeting goals. The deployment stage includes deploying the software into production and releasing it to the public.

    It also includes developing manuals for system administration, installation, and end-user functioning.

  7. 7. Maintenance and support

    All software requires maintenance. At this stage of the life cycle, technical support of the software is carried out. As long as the software is in use, you need to keep it up to date, troubleshoot potential issues, and keep it top-notch. The updates are aimed at maintaining optimal performance of the product. Constant support allows you to guarantee that the system meets modern standards and technologies.
