Cross-Platform Mobile App Development:
One Codebase. iOS and Android. Done.
Cross-platform mobile app development lets one team ship to both stores at once. You get full iOS and Android coverage without funding two separate engineering teams. Same features, same schedule, no catch.

Two native codebases can cost $220K a year in duplicate engineering. That buys nothing new.
Most product teams don't budget for the hidden cost of running separate iOS and Android codebases. Features fall out of sync. Review cycles double. Every hotfix runs twice. The coordination alone costs months of shipping time.
iOS Team
2 engineers · Swift / Xcode
Dark mode shipped on Android 3 weeks ago. iOS team has it in backlog. Users on Apple devices notice.
Android Team
2 engineers · Kotlin / Android Studio
Features out of sync. Review cycles doubled. $220K in duplicate engineering — that you could redirect to shipping features.

Pick your stage. See exactly what you get.
A three-person startup building its first mobile MVP needs a completely different scope than a 200-person company realigning two drifting codebases. Choose your situation and see how we staff and price your build.
Startup — App live in 8 to 12 weeks
You need both stores live before your next funding round. No time to hire separate iOS and Android teams.
Growth Co — Get your platforms back in sync
Your iOS and Android builds have drifted. Users on one platform are getting features that users on the other are still waiting for.
Enterprise — Compliance, security, and CI/CD
You need SSO, MDM support, native hardware integration, and a CI/CD pipeline your DevOps team controls on day one — not after handoff.

Proposal on request
Every native module integration ships with documentation. Your team owns it from day one.
Five numbers that show you the return.
One team. Two stores. Half the overhead.
You pay for one engineering team instead of two. They share the same code, the same review cycle, and the same deploy. Your budget goes to building features, not duplicating work.
Both stores ship at the same time. Every time.
No waiting for one platform to catch up. No staggered release dates that leave half your users behind. iOS and Android users get the same update, on the same day.
98% of your codebase works on both platforms.
React Native and Flutter share your API calls, data logic, and screens. The remaining 2% handles platform-specific behavior. You are not building two products. You are building one.
One fix goes live on iOS and Android together.
No separate patch queues. No platform-specific hotfixes that break the other store. Every merge covers both platforms. Your team stops tracking two bug boards.
Real hardware. First sprint week.
We configure your project, wire both store pipelines, and ship a TestFlight build before Sprint 1 ends. You test on a real device, not a mockup or a staging simulator.
Homes and Lands went live on both stores. One team. One timeline.
App Store and Google Play launched in the same sprint window. Same features. Same review date.
Native
One framework for listings, agent profiles, document scanning, push notifications, and store optimization.
Magazine listing display, agent profiles, custom document scanning, push notifications, map integration, saved searches, and app store optimization all shipped to both platforms at once.

Homes and Lands connects property buyers with agents through a mobile experience built for both iOS and Android.
Two separate native apps would have cost twice as much and taken twice as long. The client needed magazine-quality listing display, a custom document scanning feature, and app store compliance across both environments — all on a single timeline.
We built the full product in React Native. Listings, agent profiles, a custom scanning module, push notifications, and app store optimization shipped to iOS and Android in one release cycle. The app passed both store reviews on the first submission.
Key outcome
Users on both platforms received the same feature set from day one. App store compliance held across both environments. The client's team manages one codebase, not two.

Three things most cross-platform shops leave to chance. We don't.
We check store policy before we write a line. Rejections are our problem, not yours.
App Store rejections kill launch dates. Most agencies scope the code, ship you a build, and bill you by the hour to fix policy issues. We audit your feature list against current iOS and Android review guidelines before the first sprint. If a rejection happens, the fix is on us. It is not an invoice line.
One sprint review covers both platforms. Forty-five minutes, not two half-days.
Most shops send a TestFlight link and a separate APK. You end up running two separate bug review sessions. We ship one consolidated report mapped to one sprint board. Your team reviews once. Both platforms are covered. You keep your afternoon.
Your app gets camera, Bluetooth, and biometrics. No rebuild required.
Cross-platform development does not mean giving up hardware access. If your product needs Bluetooth, NFC, ARKit, or biometrics, we add native modules to the shared codebase. Ninety-eight percent of your logic stays shared. The native layer is documented and handoff-ready. You get the hardware feature without losing the single-codebase advantage.
Answers before you decide.
Yes, when built correctly. React Native and Flutter render using actual native components, not a web view. Facebook, Instagram, and many other large apps run on these frameworks. For most products, users cannot tell the difference between a well-built cross-platform app and a native one.
We support all of it. Camera, biometrics, Bluetooth, NFC, location services, and push notifications are available through native module bridges that we build and document as part of your project. During scoping, we flag every module that needs native code and show you exactly how it integrates.
We monitor both stores for policy changes. For active builds, policy updates are covered in scope. For apps already live, we can help on a retainer or per-update basis. We build your architecture so policy changes require a configuration update, not a full rewrite.
Yes. We run a screen-by-screen audit of your current app. Every component gets mapped to its cross-platform equivalent. We recommend starting with your highest-traffic screens so users stay on a working experience throughout. Your existing accounts, data, and app store rating carry over.
You own 100% of the code, repositories, and store accounts from day one. We do not lock you into support contracts. Handoff includes a live CI/CD pipeline, documented architecture, and native module guides. You also get a 30-day window where your engineers can ask questions and we make adjustments.
Is this a fit?
This works well for you if…
- You need iOS and Android with the same feature set and one review cycle
- You want both stores live before your next funding round or product launch
- You need maximum coverage without building and maintaining two codebases
- Speed to market matters more than squeezing out the last 5% of platform-native behavior
This may not be the right fit if…
- Your app's core experience depends on AR, CarPlay, or other features that only exist on one platform
- You only need one platform right now and have no plans to expand
