Native or cross-platform mobile development: which one suits the app
Native development builds a separate app for each platform, Swift for iOS and Kotlin for Android, for maximum performance and full access to device features. Cross-platform development builds one codebase that runs on both, using frameworks like React Native or Flutter, which is faster and cheaper to build and maintain. That is the summary in our native versus cross-platform guide, and the table restates its side-by-side comparison.
| Factor | Native | Cross-platform |
|---|---|---|
| Codebases | One per platform | One for both |
| Performance | Highest | Very good, near-native for most apps |
| Build cost and time | Higher, two builds | Lower, one build |
| Maintenance | Two apps to update | One codebase |
| Device feature access | Full, immediate | Full for most, occasional lag for brand-new features |
| Best for | Performance-critical, deeply native apps | Most business and content apps |
When each approach is the right call
Native
Two builds, the fullest access- The app is performance-critical: heavy graphics, gaming or real-time processing.
- It relies deeply on the latest device-specific features.
- You need the most platform-true experience and have the budget for two builds.
Cross-platform
Most business apps- You want to reach iOS and Android quickly and affordably.
- The app is a standard business, content or commerce app.
- You want one team and one codebase to maintain, and budget and speed to market matter.
On this page, Swift, SwiftUI, Objective-C and CocoaPods are shown under iOS Application Development, Kotlin, Jetpack Compose, Java and Gradle under Android Application Development, and Flutter, React Native and Xamarin under Cross Platform Application Development. Our custom software development page states where each fits: native iOS and Android where the device capability or the store requirement decides it, Kotlin on the Android and server side, and Flutter where one codebase across both platforms is the cheaper answer.
From the device in a user's hand to your systems
Figure 1 puts the seven services on this page on one path, from the device in a user's hand to the systems the app has to talk to, using the page's own words and the technologies it shows.
Figure 1. From the device to your systems, and the three ways the app in the middle can be built
Caption: the three devices come from Custom Mobile App Development above; the eleven technologies are the ones shown under iOS, Android and Cross Platform Application Development on this page; the right-hand boxes restate Integration Services and Deployment and Support; the two bands restate Enterprise Mobile Strategy, User Experience and Application Testing. Nothing in the figure is a measurement.
How an engagement runs, stage by stage
Five stages, each one a service already listed on this page, in the order the work happens. Sthenos works in two week sprints, so working software arrives every two weeks and a first production release typically lands in three to six months, as stated on our about page.
- StrategyAssess mobile readiness, define platform priorities, and design a scalable mobile roadmap aligned to business goals and long-term growth.Platform priorities and a roadmap
- DesignIntuitive, user-first mobile experiences that balance usability, performance and visual clarity across devices, workflows and touchpoints.Interface and flows
- Build and integrateCustom apps across iOS, Android and cross-platform frameworks, integrated with enterprise systems, APIs and third-party services for seamless data flow.Working software every two weeks
- Test and submitRigorous QA, device testing and automation frameworks, with the app store submission checklist built into the plan rather than treated as a formality.A build ready for review
- Deploy and supportSecure app deployment, release cycles and post-launch support, for smooth rollouts and continuous operational stability.Release cycles and support
What app store review checks before a first release
The app-store review answer on this page says to plan for a rejection cycle on a first submission, because the common causes are policy rather than code: account deletion requirements, permission justifications and sign-in options. Here is what each one requires, as Apple's and Google's own policy pages state it.
What moves the cost of the build
Mobile work is billed at the published Sthenos rate band, and where the scope is clear we quote a fixed price for a defined outcome, with a costed roadmap before any build starts. The typical project band below is the one our about page publishes across all project types.
The first six drivers below come from our guide to mobile app development cost, and the last two from our software development pages. None of them carries a number here, because a number without your scope attached to it is decoration.
Three ways to hire mobile app developers, compared
Our software development services page publishes four engagement models, shown here as three cards because fixed price and time and materials both buy a defined project. To hire dedicated mobile app developers for continuous product work, the dedicated team is the model; to add hands to a mobile team you already run, it is staff augmentation; to outsource mobile app development as a defined project, it is a fixed price or time and materials.
The three engagement models
Dedicated team
Monthly, per named engineer- Continuous product work over quarters, not a single project.
- The same people across quarters, so the knowledge stays put.
- You pay for the capacity even in a slow month.
Staff augmentation
Per person, into your team- You have the plan and the management, and need hands.
- Engineers work in your process, your board and your code review.
- You own the outcome, so weak internal direction shows up fast.
A defined project
Fixed price or time and materials- Fixed price works when the specification is genuinely settled.
- Time and materials fits scope that will evolve; set a ceiling deliberately.
- Either way, a short discovery and a costed roadmap come first.
What you receive at the end of a build
Each line below is something this page or our software development services page already commits to, stated as what ends up on your side of the table.
- The repository and the cloud accounts, in your name from the first commit.
- Platform priorities and a scalable mobile roadmap, aligned to business goals.
- Working software every two weeks, not a status report about software.
- Stable, production-ready builds, verified through QA, device testing and automation.
- An app integrated with your enterprise systems, APIs and third-party services.
- Secure deployment, managed release cycles and post-launch support.
What to ask any mobile app development company
These questions apply to any of the mobile app development companies on your shortlist, Sthenos included, and each comes from an answer already published on this site.
- Which platform ships first, and what about this app would make native worth two builds?
- Is the app store submission checklist in the plan, covering account deletion, permission justifications and sign-in options?
- Where does the back end come from, and who runs hosting, updates and security patches after launch?
- What happens to the app when the operating system changes next year?
- Who owns the code, the repository and the cloud accounts when we are done?
- Who reviews the code, and can that person veto a merge?
More questions before you build
Can you do mobile app development with React?
Yes. React Native is shown on this page under Cross Platform Application Development, beside Flutter and Xamarin. It builds one codebase that runs on both iOS and Android, as our native versus cross-platform guide explains, and our software development services page covers migrating older web and mobile front ends onto React.
What does a mobile application developer do on a Sthenos engagement?
Builds custom apps across iOS, Android and cross-platform frameworks, tailored for phones, tablets and wearables, and integrates them with your enterprise systems, APIs and third-party services. Our dedicated mobile developers work as an extension of your team, across iOS, Android and scalable mobile architectures.
Do you offer enterprise mobile app development?
Yes. Enterprise Mobile Strategy is the first service on this page, and our enterprise software development page lists enterprise mobile apps: native and cross-platform apps for employees, partners and customers, integrated with your systems.
Do you offer a mobile app testing service?
Yes. Application Testing is one of the services on this page: rigorous QA, device testing and automation frameworks. Our software testing page covers the wider service, including compatibility testing across devices, browsers and operating systems.
