Cross-Platform App Development

Cross-platform development helps to kill a lot of birds with one approach — creating one robust application that fits more than one platform by developing universal code, using common UI groundwork and facilitating the overall development process. The most typical example is developing a single mobile app that is compatible with both Android and iOS.

Cross-platform App Development Tech We Use

For years, NIX has utilized the experience and technology expertise accumulated by years of operation to deliver turn-key cross-platform app solutions across a wide range of business domains. We know how to create in-demand apps that look, feel, and function to furnish the same rich user experience across all devices.

Cross-Platform App Development Services

  • Cross-platform App Development

    We take your groundwork and create a market-ready app based on your needs while you focus on product and company growth. Or we develop an app from scratch starting from visualizing app concept and composing architecture based on peculiarities of targeting platforms and your business needs. From there, we create a comprehensive app and provide ongoing support including app store release and on-demand enhancements.

  • Extension of Your Cross-platform Development Force

    Our turn-key team strengthens your development capabilities by working as an autonomous or internal engineering force and filling the gaps in specific technology expertise. By doing so, we bring ideas and solutions to the table to accelerate engineering velocity and time-to-market.

  • PoC/MVP App Development

    Start small, win big. Before investing in a full-fledged application development test your product idea for viability, make a test run to receive valuable user feedback to gain an edge on the competition. This helps make a great showcase for investors and bulletproof your pitch.

  • Cross-platform Development Consulting

    We use our extensive experience and technical know-how to help you avoid bottlenecks when creating new products — choosing the best suited tech strategy and planning security measures before you start the development process. Our experts analyze the business idea, conduct market and audience research, create a detailed roadmap, and design proper architecture to ensure smooth operation now and in future enhancements.

    Or, perhaps you already have a product that no longer meets your business needs or doesn’t work the way you want it to — plummeting profits, low user retention, or not scalable enough. In this case, our team will perform a thorough audit of your product, including the business processes, architecture, UX appeal, and more, to help build a well-elaborated plan for required enhancements.

Our Cross-Platform App Development Process


App Strategy & Planning

We form a vision of the product based on technical and business requirements and your target audience — where the solution will be used, what is essential to the users, and composing functional/non-functional requirements. We conduct preliminary research, outline the expected scope of work, and set milestones before kicking off the project.


App Design

Knowing all cross-platform limitations, we create the best fitted UI/UX as close to native experience as possible. We assemble layouts and create style guides and clickable prototypes to experience the future app and develop a solution, where each button meets the specific needs of the user.


App Development

This involves elaborating the software architecture with required features and design. Besides app engineering, we setup backends and implement APIs and integrations with other systems.


Mobile QA Testing

We polish the application prior to release with deep, multi-level QA testing, identifying issues, fixing them, and fine-tuning functionality. The comprehensive QA phase helps save you time and money by preventing any potential issues that would otherwise lead to major glitches and loss of user loyalty.


App Release & Enhancements

We support and further improve the application after properly deploying it to app stores. We implement the extended functionality and provide ongoing support and enhancements.

FAQ on Cross-Platform App Development

Which cross-platform technology is the best for mobile app development?

The essential top leading platforms in the mobile market are Android and iOS (as always), and cross-platform mobile app development allows the most convenient coverage of both platforms without going far or spending twice as much time and costs on the project. This may serve as the game-changing approach for many companies and startups out there.

Our experts have a wide pool of technologies to realize an efficient and robust cross platform solution such as React Native, Flutter, SwiftUI, Kotlin Multiplatform, Jetpack Compose, Unity3d.

We can help you choose the most suitable framework/technology tailored for your business needs, target audience, as each tool has its own strengths and requires an individual approach.

What are some examples of cross-platform apps?

Cross-platform apps have been introduced by some of the largest companies, giving us such popular apps as Facebook, Uber Eats, Shopify, Tesla, Instagram, Pinterest, Google Assistant, eBay, Groupon, Alibaba, and many more. Besides mobile apps, the cross-platform app development approach covers solutions from desktop and laptop apps to TV and wearable app development.

Is native better than cross-platform?

One cannot say what is ultimately better. Each approach is the best for the purpose it was initially created for. Native applications cannot be outrun in terms of performance, but building them requires more time and effort (and costs, respectively). Cross-platform apps may not have the same performance speed and reach as native apps, yet they are up to 40% quicker and cheaper to release.

Is cross-platform app development worth it?

In terms of cross-platform app development technology, it allows creating reliable, smooth-running, beautiful looking applications able to address the business challenges of companies of any size. If you are OK with not having the fastest performance, without native UI/UX (and the most expensive accordingly) and application on the market, creating such a solution is certainly worth it. But make sure to get a professional consultation first.

Buzz Sharifi

Account Manager at TransGrade, CRM

“Extremely detailed, professional, attentive”
We’ve been working with NIX for over a year now and have nothing but good things to say about them and their talented pool of developers, staff members, and executives. They are extremely detailed, professional, attentive, and deliver top-quality work within the time estimates that they provide. What else can you ask for? I highly recommend NIX for all tech-related projects.

Christian Rohner

Project Manager at Information Products AG

“Quality of delivered work is outstanding”
Our company worked more than 5 years in total with NIX. Communication was always very clear and direct. Being a remote company, wasting time in communication is horrible, luckily with NIX, we experienced no delay or misunderstanding. Quality of delivered work is outstanding, all tasks prior to delivery were tested in detail, and bugs or mistakes were virtually non-existent.

Craig Burris

Director of Operations at CarSoup

“It is hard to impress me, and NIX kept me happy”
There is no recommendation that is more powerful. NIX’s expert team built a new system that increased potential customer traffic and improved performance. Their transparent workflow allowed for consistent communication and quick correction of problems when they arose. They also adjusted their processes to mitigate time-difference concerns.

Eric Spear

SVP of Engineering at Cengage

“Delivering high-quality code”
With NIX, I have broken some of my own rules of team composition with respect to the ratio of FTE and 3rd party engineers. I have some teams that are more than 50% NIX because the code coverage, quality, and velocity coming out from the NIX developers are very good. Delivering high quality code in a predictable manner has built trust and confidence with my management/full-time employees.

Ilya Kottel

VP R&D at HumanEyes

“You have done the work perfectly”
I want to say thank you for the excellent, highly professional work, for your passion, and your time even on holidays and weekends. Your attitude ultimately led to outstanding results. We are satisfied with the result we’ve achieved, but we need to keep working, and actively use every opportunity to make it better. You have done the work perfectly and the application, which you created in such a short time, turned out to be very functional and cool.

Jeremy Reither

Consultant & Advisor at DemandSide

“CMS team are my go-to partners for web dev”
I’ve been working with these guys for years now – particularly their CMS team. The relationship has been very positive, and they continue to do great work for me. I first hired NIX around 2008 to re-build a website that was built (poorly) by another agency. NIX solved that problem and has helped me build and launch multiple products since then. Roman and his CMS team are my go-to partners for web dev.

Mark DeJarnatt

Chief Technology Officer at Sparkle Stories LLC

“Quickly and professionally”
I have used NIX for 3 different companies over the past 3 years that I have been CTO of. Projects have spanned a wide variety of technology stacks. Nix has come through each time with the right project manager, quality assurance, business analyst, DevOps, and developers. They quickly and professionally get up to speed with our current processes and seamlessly merge with any professional environment.

Noam Shalit

COO at SafeRide Technologies Ltd

“The team is experienced and professional”
We cooperate really well with them, and they make adjustments so we don’t have any complaints. The original project was successful, so they’ve extended the partnership. Headed by a knowledgeable project lead, the team is experienced and professional. NIX delivered everything on time and was always in contact with their partner. Offering a superior customer experience, they’re recommended.

Steve Berardelli

Sr. Director of Engineering for MindTap

“NIX is doing an amazing job”
NIX team contributed a lot to the process improvements for code deployment practices. So not only we write clean/stable code now but also, we are able to deploy it a lot more successfully and faster. We have a better strategy for our branch cutting and code repositories. It takes much less time to deploy code now with a higher level of stability. NIX team also contributed their ideas and views on how we can break up work among team members more effectively.
