Cross-platform apps
Flutter and React Native builds that ship to both stores from one codebase — without feeling like a compromise.
01What we build
Both platforms. One team. No excuses.
Whether it's a single Flutter codebase or fully native Swift and Kotlin, we pick the approach that fits your product — not our preferences.
Fully native apps
Swift and Kotlin when the product demands it — camera pipelines, background services, platform-deep features.
Offline-first data
Local storage and sync engines built for subway tunnels and rural coverage — the app just works.
Push & live tracking
Notifications, geolocation, and real-time updates — the features that make ride, delivery, and travel apps tick.
Store submission & release
App Store and Play Store review, certificates, and phased rollouts handled for you — rejections included.
App rescue & rebuilds
Inherited a crashing app or an unmaintainable codebase? We stabilize first, then rebuild piece by piece.

02How an app ships
Tested on real hardware, not just simulators.
Prototype on-device
A clickable prototype on your own phone in week one — decisions get made with thumbs, not slides.
Design for both platforms
One product language that still respects iOS and Android conventions — no uncanny half-ports.
Build & test on real devices
Weekly TestFlight and internal-track builds, tested across a rack of real phones — old ones included.
Submit, launch, iterate
Store review handled, crash reporting live from day one, and a release cadence that keeps ratings up.

04Questions
Before you ask.
Native or cross-platform — which should I choose?+
For most products, Flutter or React Native gets you both stores at roughly 60% of the cost of two native apps. We recommend native when you need platform-deep features — heavy camera work, background processing, or demanding animations. We'll tell you honestly which fits, in the first call.
Do you build the backend too?+
Yes. Most of our apps run on APIs we design alongside them — auth, payments, notifications, and admin panels included. One team, one contract, no integration finger-pointing.
What if Apple or Google rejects the app?+
Store review is our job, not yours. We build to both stores' guidelines from the start, handle any rejection responses, and resubmit until it's live — at no extra cost.
How do updates work after launch?+
Crash reporting and analytics run from day one, so we see problems before your users report them. Support retainers cover OS updates, bug fixes, and small features on a regular release cadence.
