The real cost of building separately
Two teams for one app is not a strategy.
Most teams underestimate what maintaining two separate native codebases actually costs. In coordination drag, feature divergence, and time to ship.

Scoped to your stage
Built for where you are now.
Cross-platform development looks different at a three-person startup than it does at a 200-person scale-up. Select your context below to see how we scope and staff your build.
MVP to first users, fast
You need validated traction on both stores before Series A, without hiring two native teams.
Feature parity and performance
Your iOS and Android apps have diverged. You need both platforms back in lockstep with a scalable architecture.
Compliance, single sign-on, CI/CD
You need mobile device management support, native module integration, and a CI/CD pipeline your DevOps team can own.

What you actually get
The outcomes that make the return on investment obvious.
40%
Lower build
cost
One engineering team. Both platforms.
Shared business logic, shared state management, shared design tokens. You fund one team instead of two, and they ship to both stores simultaneously.
2×
Faster to
market
Ship to both stores in the same sprint cycle.
No waiting for the Android team to catch up. No staggered release windows. Features go live across iOS and Android in the same deploy.
98%
Code reuse rate
Business logic shared across every screen.
React Native and Flutter share API calls, state, validation rules, and user interface components. The 2% that differs is platform-specific polish, not a separate product.

Bug fixes, updates, and features deploy simultaneously.
No iOS-only patches that break Android parity. No Android hotfixes that sit in a separate queue. One merge, both platforms.

Your first testable build ships within days of kick-off.
We scaffold the project, configure both store build pipelines, and hand you a TestFlight build before the end of Sprint 1. You give feedback on real hardware, not prototypes.

Homes and Lands is a real estate platform that displays property listings and connects buyers with agents across digital channels.
Challenge
The platform needed a user-friendly mobile application for both iOS and Android that showcased listings and agent details, including a custom document scanning feature, while meeting strict app store security and performance standards across both environments. Two separate native apps would have doubled the timeline and doubled the team cost.
Result
A full-cycle cross-platform build was delivered using React Native, supporting scalability and platform efficiency. New mobile features, including listing display, agent information, and a custom scanning interaction, shipped to both iOS and Android simultaneously. App store listing optimization drove visibility and downloads from launch day.
Key outcome
Both platforms launched with high user engagement and positive feedback. Strong security, cross-platform compatibility, and app store compliance ensured trust and sustained growth in a competitive real estate market.

How we differ
Three things other partners skip.
01
We scope per platform store policy, not per codebase line count.
App Store review rejections can kill your launch date. Most cross-platform partners scope the code and hand you a build and then charge hourly for rejection fixes. We audit your feature list against current iOS and Android store policy before we write a line. Review rejections are on us, not on your invoice.

02
Your team reviews one build, not two separate quality assurance cycles.
Most shops send you a TestFlight link and a separate APK. You spend your sprint review managing two different bug reports on two different platforms. We use a unified testing framework that produces one consolidated bug report mapped to one sprint board. Your review takes 45 minutes, not two half-days.

03
Native modules ship when the platform demands them, without rebuilding from scratch.
Cross-platform does not mean you sacrifice hardware access. If your product needs Bluetooth, NFC, ARKit, or device-level biometrics, we bridge native modules into the shared codebase so 98% of your logic stays shared and the native layer is a clean, documented extension, not a workaround.

Common questions
Answers before you decide.
Yes, when built correctly. React Native and Flutter render using native user interface components or a high-performance rendering engine, not a web view. Apps built on these frameworks are used by billions of people daily, including apps from major consumer brands. The perceivable difference between well-built cross-platform and native apps is negligible for most use cases.
Hardware access is handled through native module bridges, which we write and document as part of the project. Camera, biometrics, Bluetooth, NFC, location services, push notifications: all of these are supported without compromising the cross-platform architecture. We will flag during scoping which modules require native code and exactly how they integrate.
We monitor both stores for policy changes and flag anything that affects your build. For projects in active development, policy-related updates are included in scope. For shipped apps, we can support on a retainer or per-update basis. Either way, your architecture is built with policy headroom so updates require a configuration change, not a rewrite.
Yes. We run a screen-by-screen audit of your existing app and map every component to the cross-platform equivalent. We recommend a phased migration, starting with the highest-traffic screens, so users are never on a degraded experience during the transition. Your existing users keep their accounts, data, and app store rating.
You own 100% of the code, repositories, and store accounts from day one. Handoff includes a working CI/CD pipeline configured for your team, documented architecture, native module integration guides, and a 30-day handoff window where your engineers can ask questions and we make adjustments. We do not lock you into ongoing support contracts.
Is this a fit?
This works well for you if…
- You need both iOS and Android with the same feature set
- You want one team reviewing one sprint, not two
- Budget is limited and you need maximum platform coverage
- Speed to market matters more than bleeding-edge platform user interface
This may not be the right fit if…
- Your app's core value is deeply platform-specific user interface behavior (for example: AR, CarPlay)
- You only need one platform for now and may never expand
