Why Cross-Platform App Development?

Cross-platform mobile app development is the process of developing a mobile solution, not for a specific device but multiple platforms and operating systems. When building cross-platform apps, mobile developers use programming languages and technical options not related to a single OS. Built apps are packaged into virtual “containers” that allow them to work and interface with each platform. Therefore, your app can reach more users without ignoring any section of your user base or target audience.

Along with a bigger reach, cross-platform mobile app development services can provide the following benefits:

Reusable code

Mobile app developers can use the same code across all platforms. It also decreases the number of repetitive tasks, thus eliminating drudgery.

Reduced development time

Due to a single script, app development is going much faster. As a result, your product can reach the market sooner than before.

Easier implementation

Utilizing already known resources and translating them for different platforms makes custom mobile app development quicker and easier to sync updates across all mobile devices.

Uniformity

Cross-platform app development ensures that the overall look and feel of the app can be maintained across all platforms since the same set of code is being utilized.

Get the Most out of React Native Technology

React Native is the perfect combination for companies looking for mobile application development services and creating a solution with native UI using the tool of their choice, Javascript. React Native is one of the most wanted frameworks for startups and SMEs. It helps reduce mobile app development costs and accelerate time-to-market while reusing a larger part of the codebase across Android and iOS.

At our mobile app development company, React Native developers apply their vast knowledge of React architecture and React Native libraries to create engaging mobile experiences written in JavaScript using SDKs inherent in both Android and iOS.

Why React Native

Cross-platform advantages

React Native is highly rated by mobile app development companies because it offers cross-platform APIs, letting you create completely native mobile apps for both Android and iOS by keeping a single codebase.

Efficiency and agility

As one of the best mobile app development frameworks, React Native provides great advantages such as a rich ecosystem, excellent community support, open-source benefits, and agility.

Native UI

React Native provides a core set of platform-agnostic native components that map directly to the platform’s native UI building blocks. That allows you to build interactive and user-friendly interfaces without compromising your users’ experiences.

Live updates

All changes made in the code can be easily visualized by refreshing the app just like a web page. The updated app can be immediately pushed directly to users’ devices without re-publishing in the store.

Benefits of Tapping into Mobile App Development Services

From e-commerce stores and the banking sector to food delivery and educational institutions, we can hardly find an industry where mobile applications have not proved their value as revenue generators or established themselves as key communication channels with customers. Here are some benefits your business can gain from custom mobile app development services:

Increase brand awareness

Mobile app software can work as an extension of your brand while having rich advertising potential. By expanding your offerings to a new platform, you can reach broader audiences and new demographics of customers. The more often users interact with your brand via your mobile app, the more likely or inclined they will be its adherents.

Establish a direct marketing channel

Mobile app development will help you build a direct marketing communication channel with customers. With such features as news feeds, messaging, forms, and push notifications, it can provide and gather various information with minimum effort.

Provide value and cultivate loyalty

Another reason why you should consider going for custom mobile app development is to give customers more value and encourage their loyalty. Rather than issuing the old-collection card, you may provide hyper-personalized user experiences, bespoke discounts, coupons and programs, and even gamification elements - all within one app.

Get ahead of the competition

The world is going mobile, and people make new demands on services and products they use. By creating a mobile application with unique and exclusive features like, for example, cryptocurrency payments or VR clothing, you will truly stand out from the competition while getting ahead of the curve.

Agile Mobile App Development Process

From the discovery phase through design, development, QA, and maintenance, we follow a low-risk mobile app development process underpinned by continuous delivery and seamless integration into the client’s release cycle.

Discovery & Planning

In the discovery phase, we explore your business objectives, conduct market analysis, and plan how your mobile app can effectively tackle user needs and create engagement.

After that, we help you translate your requirements into a feature list, choose the optimal tech stack and plan key project milestones.

Design

We start to bring your project to life by establishing user personas, flows, and journey maps and then creating compelling and aesthetically pleasing user interfaces that will engage and delight users while driving conversions and strengthening the customer-company relationship.

Development

Our developers will leverage their experience and skills to work out the optimal mobile solution architecture and deliver all required functionality. We will apply cutting-edge technologies and implement most advanced integrations to provide the best app performance, connectivity, and scalability.

Testing

We make sure the code we develop is clean, effective, and free of bugs through continuous testing. We test your product using multiple rounds of testing, including automated and manual testing and functional and UI/UX testing.

Deployment

On the deployment stage, we configure CI/CD, prepare a clean, complete build of the app, and release it for internal testing. Once all tests have been successfully passed, we create a product version of the app ready to be deployed at the marketplaces.

Maintenance

Through continuous performance monitoring and bug-fixing, analyzing customer feedback, adjusting to new versions of mobile operating systems, and implementing new features, we ensure your mobile app will deliver a stunning user experience 24/7/365.

Release

Iterative development creates the conditions for quicker improvements and faster releases, contributing to early value delivery while ensuring stable and error-free functioning of the mobile solution.

Frequently Asked Questions

What is mobile app development?

Mobile application development is the process of building software that operates on mobile devices. This kind of software uses the network connection to interact remotely with computing resources. Hence, the mobile app development process involves creating installable software bundles (code, binaries, assets, etc.), implementing backend services such as data access with an API, and testing the application on target devices

What services do app developers provide?

Mobile app development companies usually elaborate their custom service offering based on their competence, strengths, market demands, businesses they aimed at, etc. But if we look at full-cycle app developers, their service proposition must comprise:

  • Mobile app project ideation and discovery;
  • Mobile consulting and prototyping;
  • Mobile UI/UX design;
  • Native and cross-platform mobile app development;
  • Mobile integrations and customizations;
  • Automated QA and testing;
  • Maintenance and post-launch support.

What programming language to use for mobile app development?

The choice of a particular technology for mobile app development depends on your business goals, the type of application needed, its requirements, etc. But firstly, you must select the OS platforms your app will work on.

If you are looking for a native app, the answer is easy: Swift or Objective-C for iOS and Kotlin/Java for Android.

If you want to leverage the advantages of cross-platform app development, we recommend you bank on React Native or Flutter.

How much does it cost to develop a mobile app?

When we estimate mobile app development, there can be a big discrepancy in costs due to the type of the app, its complexity, and the number of platforms.

A simple app version with a minimum feature set and mobile app development services for one platform costs about $35,000-40,000. Creating a large app with a complex design, advanced feature set, and support for 2+ platforms may go up to $150,000 and higher. In this case, cross-platform app development can be a feasible strategy saving up to 40% of your budget.
