Cross-Platform App Development Services

Northell holds comprehensive expertise in providing cross-platform app development services to startups, SMBs, or enterprise-level organizations across a wide range of business domains. Our team creates fast, personalized, and easily scalable cross-platform apps that work across multiple operating systems and devices. We have a solid development background and proven knowledge of the best technology stacks for building cross-platform apps from scratch and customizing solutions through implementing integrations, modifying functionalities, and adding new features.
Focusing on the customer’s needs, our tech experts create high-performing cross-platform apps with a single source code to drive conversions and reach wider audiences on both IOS and Android platforms with less effort, time and costs.

Our Cross-Platform App Development Key Points

  • Cost efficiency

    By building one app to reach both IOS and Android users, we can significantly minimize your development costs and further maintenance of cross-platform apps. A single codebase, a common UI framework, and a well-established development process allow our team to deliver high-quality results with limited financial resources. Customized to your company’s needs, we realize your unique business ideas and provide native-like solutions in an efficient and budget-friendly way.

  • Easy integration with Cloud

    Cross-platform apps support several plugins, making them easy to integrate with Cloud. We use these powerful capabilities, so your app can benefit from various plugins. Since the code is well-coordinated with multiple plugins and extensions, we can easily extend the app’s functionality and enhance scalability.

  • Cross-platform uniformity

    The development of multiple apps is often challenging to keep in sync between different teams and often results in creating various design concepts. Cross-platform apps promote uniformity on any device your customers use. Our design and development teams use cross-platform development tools to build a uniform user experience and deliver brand consistency across all platforms and devices.

  • Clean and quality code

    For each project, our experienced cross-platform development team follows the best code quality practices to create bug-free, modern, and compliant apps. We write clean, easily maintainable code to prevent app inconsistencies and minimize bugs. Our well-structured code lines are written using the most powerful programming languages, such as JavaScript, Dart, and others.

  • Quick time to market

    We follow a time-tested development workflow allowing us to optimize the process to deliver high-quality results fast and iteratively. When building cross-platform apps, you get the maximum benefit of code reuse and on-time delivery because your team doesn't have to code twice. Our cross-platform geeks write code once to deploy on multiple platforms and start generating profits for your business earlier.

  • High engagement and usability

    Our seasoned cross-platform development team creates responsive cross-platform apps with improved user engagement, consistent brand positioning, and exceptional usability across all platforms and devices. We help your global audience grow by making your customers enjoy your product from their mobile devices on the go.

1 Product discovery and planning

This stage is aimed at analyzing your business needs and project requirements. We organize workshops and interviews to collect as much information as possible, create technical documentation and plan the cross-platform development process.

2 UI/UX design

During the design stage, we create brand-oriented style guides and clickable prototypes of your future cross-platform solution based on your requirements to meet all your business and target audience needs. We know all the ins and outs of cross-platform to create the most appropriate UI/UX design close to the native app experience.

3 Development

We assign back-end coders to implement the application’s server side, APIs, and business logic, and front-end developers to transform UI design into a functioning user side. Using pre-defined technical documentation, cross-platform developers write code according to your requirements.

We follow the best practices of cross-platform development services delivery, including Agile project management, CI/CD, regular code reviews, code quality control, test-driven development, regular communication, etc.

4 QA & Testing

Our QA engineers polish the application prior to release by doing multi-level QA testing, identifying issues, and fine-tuning functionality throughout the development process. We test usability, performance, acceptance, and functionality to ensure your app runs smoothly across multiple platforms and delivers a high-quality experience to end users.

5 Deployment & Integration

Next, we deliver the application to users for beta testing. After receiving feedback from users, we make adjustments and improvements if needed. At this step, our primary goal is to ensure that the new cross-platform solution is hack-proof and bug-free.

6 Maintenance

We focus on long-term cooperation with our customers and offer ongoing application support, regular functionality updates, and troubleshooting. Our team is always in touch and ready to keep your cross-platform application running smoothly and maintaining working capacity at any time!

FAQ

How much does it cost to develop a cross-platform app?

The cost to develop cross-platform apps depends on your unique project needs, tech complexity, functionality scope, types of integrations, available resources, and other individual needs. So, the exact price is clear once you understand what type of solution you want to build and what goals you want to achieve.

On average, the cost of creating cross-platform applications starts from $24,000.

Either way, at Northell, you can find flexible hiring (dedicated team, IT augmentation, project-based outsourcing) and pricing models (project-based, hourly or dedicated team) to suit your needs, expectations, and budget best.

How long does cross-platform app development take?

On average, it takes 4-6 months to develop cross-platform apps. The simple apps may take even a few weeks, while more complex ones take more time to develop. In any case, cross-platform development requires building a single codebase once to run on multiple platforms. Hence, it takes less time than building native apps for different platforms twice.

Timeline estimates depend on the functionality scope, unique business needs, team composition, project complexity, and scale. Share your requirements with us so that we can prepare a precise project estimate.

What tech stack do you use to build cross-platform applications?

We use our extensive expertise and technical know-how to build up-to-date and feature-rich cross-platform apps based on the most robust tech stacks and the latest technologies. Thus, our team uses the following technologies and tools to build cross-platform apps and drive stable development progress:

  • Frameworks: Flutter, React Native, React.js, Xamarin, Ionic, Cordova
  • Front end: React, Vue, Angular, Flutter 
  • Databases: MySQL, PostgreSQL, MongoDB
  • Programming languages: Javascript, Dart
  • Deployment: AWS, Azure, Google Cloud, Kubernets, Docker 
  • Native technology: Swift (for IOS), Java, and Kotlin (for Android)
  • PM tools: Jira, ClickUp, Slack 
  • Testing tools: Selenium, Jenkins, Test Rail

There are many situations when our customers’ unique project requires specific tech stack and frameworks. In that case, we tailor the tech stack’s choice to serve our customers’ needs best.

What platforms do you provide cross-platform apps for?

Cross-platform technology provides many opportunities to create a flawless user experience that allows you to reach and retain more users, regardless of the devices they use. Thus, we provide cross-platform solutions for the following platforms:

Which solution is better: native or cross-platform?

There is a definite difference between developing native and cross-platform applications. While native apps are created to run on a specific platform and installed on the device, such as IOS or Android, cross-platform application development tends to be compatible across multiple platforms, sharing a single codebase.

Moreover, the cost and time to develop cross-platform apps are relatively lower than native development. At the same time, native apps are more secure and highly performant than cross-platform solutions but require more time, effort, and costs.
