The Honest Version: We Build Both Cross-Platform and Native

Here is the straight answer before you read further. We build mobile apps both ways. Cross-platform with Flutter and React Native, where one codebase compiles to both iOS and Android so you ship two apps with one team. And native with Swift for iOS and Kotlin for Android, where each platform gets its own purpose-built codebase.

For most products, cross-platform is the sensible default. It is faster to build, cheaper to maintain, and modern frameworks handle the large majority of apps, including native device features like camera, GPS, push notifications, and payments, through native modules. Native wins when your app depends on platform-specific power, the latest OS features on day one, heavy on-device processing, AR/VR, or high-end graphics. For those, a dedicated Swift or Kotlin build serves you better.

The honest part is this. We offer both, so we have no reason to push you toward the one we would rather sell. We will recommend cross-platform for most products and native when it genuinely wins for yours. If cross-platform is the right call, we will say so. If native is, we will say that too.

The Two Approaches We Build In: Cross-Platform and Native

Cross-platform ships to iOS and Android from one codebase. Native gives each platform its own purpose-built codebase. Which one fits depends on your product, your team, and how much platform-specific power you need.

Cross-Platform (one codebase, both stores)

Flutter

Google's cross-platform framework, one codebase in Dart, a single design system across iOS and Android, and strong performance for rich, custom UIs. Best when you want pixel-consistent design and smooth animation across both platforms.

React Native

Facebook's cross-platform framework, one codebase in JavaScript and TypeScript, and the React model shared with your web team. Best when you already have React on the web or want to reuse front-end skills across web and mobile.

Hire React Native developers →

Native (a purpose-built codebase per platform)

Swift for iOS

Hire an iOS developer, or a Swift developer, who builds in Swift and SwiftUI. Best when you need the newest Apple features on day one, deep integration with iOS hardware and frameworks, or high-end graphics and performance on iPhone and iPad.

Kotlin for Android

Hire an Android developer, or a Kotlin developer, who builds in Kotlin and Jetpack Compose. Best when you need the latest Android APIs, tight integration with the device and Google services, or heavy on-device processing across the Android ecosystem.

Not sure which fits? That is a good first conversation. We will recommend cross-platform or native, and the specific framework within it, based on your product, your team's existing skills, and your performance needs, not based on which we would rather sell.

Cross-Platform or Native: When Each One Wins

We build both, so this is the straight version to help you decide before you hire. Cross-platform is the right choice for the large majority of mobile products. Native wins when your app needs platform-specific power.

Cross-platform is right when

You want to launch on both iOS and Android without building and maintaining two separate codebases.
You are an early or growth-stage product where speed to market and budget matter.
Your app is UI-driven with standard device features like camera, GPS, push, payments, and offline.
You want one team you can scale, not two native teams to hire and coordinate.

Native is right when

Your app leans on cutting-edge, platform-specific APIs or the newest OS features on launch day.
You need heavy on-device computation, AR/VR, or very high-performance graphics.
You have a large existing native codebase you are extending rather than starting fresh.
You want the deepest possible integration with iOS or Android hardware and frameworks.

For these, we staff native Swift (iOS) or Kotlin (Android) engineers, and we will tell you when that is the better fit.

Why Teams Choose Us Over Marketplaces

Marketplaces give you a resume. We give you a teammate.

Named Engineers, Not a Rotating Pool

You will know your mobile developer by name. They learn your codebase, your product decisions, and why things were built the way they were. We do not rotate people off your project when something shinier comes along.

Vetted Before You Meet Them

Every engineer we propose is a full-time member of our team, screened on real mobile work in Flutter, React Native, Swift, or Kotlin, not keyword-matched. You still interview them directly before deciding.

Two-Week Embedded Trial

Before any long-term commitment, your developer joins your team for two weeks. Same Slack, same Jira, same code reviews. You see how they work before you decide.

Partnerships That Actually Grow

PerformLine started with one of our engineers and grew to eight-plus over two years, full-stack, DevOps, QA, and data. That is what happens when engineers care about the product they are building.

We Built Our Own Product

Formester is our SaaS product, live in production with real users and a 4.7 rating on G2. Building our own product taught us what ownership feels like, and we bring that mindset to every project.

Productive From Week One

Our engineers ramp on your codebase in one to two weeks. We track time-to-first-PR because we know you are hiring for output, not warm bodies.

Flexible Hiring, No Lock-In

Dedicated (Full-Time)

Best for: Long-term product development

A full-time mobile developer embedded in your team. They attend your standups, use your tools, and work exclusively on your product. The closest thing to an in-house hire without the overhead.

Part-Time

Best for: Ongoing feature work or maintenance

A dedicated mobile developer for 20 hours per week. Ideal when you need consistent, reliable output but do not have a full-time workload. Same engineer, every week.

Project-Based

Best for: Defined scope with clear deliverables

A mobile developer (or small team) for a specific app with fixed milestones. We scope it together, agree on deliverables, and build it. Clear start, clear end, clean handoff.

All models start with a two-week trial. Monthly rolling after the initial three-month commitment. No long-term lock-in. Our resource augmentation and full project delivery pages walk through each engagement.

From First Call to First Commit

Discovery Call

We learn about your app, your users, and whether cross-platform or native fits best, then which framework within it. No generic pitches, just a real conversation about your product and goals.

Engineer Matching

Based on your framework, domain, and team culture, we propose specific engineers, pre-vetted on real mobile work, not resumes from a database. You interview them directly. No account managers in between.

Two-Week Trial

Your mobile developer joins your team for a two-week embedded trial. Same tools, same standups, same code reviews. You see real output before any long-term commitment.

Ongoing Partnership

If the trial works, we keep building together. Monthly rolling engagement after the initial commitment. Scale up, scale down, or add complementary skills as your product grows.

You talk to the engineers who will actually build your app. No account managers translating in between.

Frequently Asked Questions

Do you build native iOS and Android apps, or cross-platform?

Both. We build cross-platform apps with Flutter and React Native, where one codebase ships to both the App Store and Google Play, and we build native apps in Swift for iOS and Kotlin for Android. Cross-platform is faster to build and cheaper to maintain, so it is the right call for most products. Native wins when your app needs platform-specific power or the newest OS features on day one. Because we offer both, we recommend the one that fits your product, not the one we would rather sell.

Can I hire a native iOS or Android developer from you?

Yes. You can hire a native iOS developer who works in Swift and SwiftUI, or a native Android developer who works in Kotlin and Jetpack Compose. We also staff native mobile app developers who cover both platforms. This is the right path when you need deep hardware integration, day-one support for the latest OS features, heavy on-device processing, AR/VR, or high-end graphics. Every native engineer is a full-time member of our team, and you interview them directly.

Will a cross-platform app feel as good as a native one?

For most apps, yes. Flutter and React Native render smooth, responsive interfaces and reach native device features like camera, GPS, push notifications, and payments through native modules. Users generally cannot tell the difference. The cases where native still wins are heavy on-device computation, AR/VR, high-end graphics, or day-one use of the newest platform APIs. We build both, so we are upfront about which camp your app is in rather than steering you toward one.

Should I choose Flutter, React Native, Swift, or Kotlin?

For cross-platform, choose Flutter when you want a consistent custom design and smooth animation across both platforms from one Dart codebase, and choose React Native when you already use React on the web or want to share JavaScript and TypeScript skills across web and mobile. For native, choose Swift when you are building for iOS and want the deepest Apple integration, and choose Kotlin for the same on Android. We help you decide based on your product and your team, then staff engineers who work in that stack day to day.

How much does it cost to hire a mobile app developer?

Rates depend on seniority, engagement model, and whether you go cross-platform or native. Because we are based in India and most clients are in the US, UK, Canada, and Australia, you get senior mobile talent, cross-platform or native, at a fraction of local hiring cost. Cross-platform also lowers the total build cost further because one codebase covers both platforms. Book a call and we will give you a specific quote based on your app and scope.

Can you publish my app to the App Store and Google Play?

Yes. We handle build configuration and help you through submission and release management for both the Apple App Store and Google Play, including the review process. Store developer accounts are typically registered in your name so you keep full ownership of your listings.

Can the same team build my web app too?

Often, yes. React Native shares its model with React on the web, and many of our engineers work full-stack. If your product spans web and mobile, we can put together a team that covers both. See our full-stack and React pages for how that works.
