A laggy, crash-prone app gets deleted and one-starred within a week. We build and launch native-quality iOS and Android apps with React Native, Flutter, or native Swift and Kotlin — fast, offline-ready, and engineered to retain the users you paid to acquire.

The bar is a five-star app
Acquisition is expensive, so retention is everything. We build for the things that bring users back: speed, reliability, offline resilience, and an experience that feels native on both platforms.
Sub-second launch, 60fps scrolling, and small download size — the difference between an app that earns a home-screen spot and one that gets deleted in a week.
React Native or Flutter ships iOS and Android together — native quality without paying for two separate teams or maintaining two products.
Local storage and conflict-safe sync keep the app usable on a subway or a job site, then reconcile the moment the connection returns.
Push notifications, analytics, and smooth onboarding designed to bring users back — because installs mean nothing if nobody opens the app twice.
From idea to the stores
Four steps take your app from a flow on a whiteboard to a five-star listing on both stores — with real users testing along the way.
We design store-ready UI and the core flows around mobile patterns and gestures — not a desktop layout squeezed onto a phone.
One React Native or Flutter codebase, with native modules where performance demands, and offline-first data from the start.
TestFlight and Play Console betas put builds in real hands, with crash and performance monitoring wired in to catch issues early.
We handle store submission and approval, launch, and post-launch updates driven by analytics and user feedback.
A mobile app, in production
A fitness startup had a slow, crash-prone app users abandoned after a week. We rebuilt it on React Native with offline workouts and a retention-first onboarding flow.

“Our first app got one-starred for crashing and people churned in days. The rebuild launches instantly, works offline at the gym, and our rating went from 2.6 to 4.8. Retention more than doubled — it's a different business now.”
Straight answers
Most apps run on a transparent monthly team rate or a fixed price set after a short scoping phase. Building iOS and Android from one React Native or Flutter codebase typically costs far less than two separate native teams — without sacrificing native quality.
We specialize in React Native and Flutter for high-quality apps that share one codebase across iOS and Android. For performance-critical features we drop into native Swift and Kotlin, so you get native quality with cross-platform economics.
A focused app typically goes from kickoff to the stores in 6–12 weeks, including beta testing on TestFlight and Play Console. We ship in increments so you can put builds in real users' hands early.
Yes — we manage the full submission process, including Apple App Store Review Guidelines and Google Play policies, app store assets, and review responses, so you get approved on the first try instead of bouncing off rejections.
Yes. We implement local storage and sync (SQLite, Realm, or WatermelonDB) so the app stays usable without a connection and syncs cleanly when the network returns — essential for retention in the real world.
