Senior engineers with 12–15 years of enterprise experience who have shipped apps used by real users — not prototypes, not MVPs abandoned after launch. iOS and Android from one codebase. Push, payments, offline, maps. Full App Store submission support.
Discuss Your Project →Getting an app on the App Store is the easy part. Getting it to stick — that requires engineering, design, and experience. Here is what we build.
React Native with Expo — a single codebase delivering a polished experience on both platforms simultaneously, without compromising on native feel or performance.
User-facing apps designed for acquisition, activation, and retention — onboarding flows, personalisation, social features, notifications, and App Store optimisation.
Apps for field engineers, delivery staff, sales teams, and warehouse workers — offline-capable, fast to use, and integrated with your internal systems.
Stripe React Native SDK, Apple Pay, Google Pay, SCA-compliant 3D Secure, and in-app purchase (IAP) integration for subscription apps.
APNs and FCM integration, deep linking from notification tap, user preference management, silent push for background sync, and notification analytics.
Local data storage with SQLite or WatermelonDB, background sync with conflict resolution, and queue-based action submission for intermittent connectivity environments.
Google Maps or MapLibre integration, background location tracking, geofencing, route display, place search, and proximity-based features.
Full submission support: metadata, screenshots, privacy policy, entitlements, review navigation, and rejection response. We have done this hundreds of times.
Tools like Adalo, Glide, and AppGyver get you moving fast on simple workflows. But they hit hard limits on performance, offline capability, custom animations, hardware integrations, and App Store review compliance. The moment your product needs anything non-standard, you are rebuilding. We build real apps that have no ceiling.
Mobile agencies often separate app development from backend development — two teams, two sets of assumptions, friction at every integration point. We build the mobile app and the API backend as one coordinated effort. The mobile engineer and the backend engineer sit in the same standups. The result is apps that actually work end-to-end.
A single mobile freelancer can build the screens. But your app also needs a backend API, push notification infrastructure, payment integration, admin tooling, and App Store submission expertise. These require different specialisations. Our studio covers the full scope — you get a coordinated team, not a patchwork.
Most mobile app projects start with an MVP build and evolve through product scaling engagements once they are live. See our full set of capabilities, read about how we work, or learn more about the team behind The Yellow Labs.
We bill hourly from $40/hr. A focused MVP mobile app typically runs 150–350 hours for a cross-platform React Native build. A production consumer app with auth, payments, push notifications, offline support, and a backend API generally falls between 300–700 hours. A complex app with real-time features, mapping, or device hardware integration runs higher. We scope carefully and report hours weekly.
For the vast majority of apps, React Native is the right choice. You get a single codebase, iOS and Android delivered simultaneously, and no meaningful compromise on performance for typical app interactions. Native makes sense only for apps that are deeply tied to platform APIs — ARKit, Core ML, advanced Bluetooth, or frame-rate-sensitive games. We use React Native with Expo for most projects, and we are transparent about where native would genuinely serve you better.
Yes — full submission support including app metadata, screenshots, privacy policy preparation, entitlements configuration, and navigating the App Store review process. We have been through hundreds of review cycles and know what Apple and Google look for. If a submission is rejected, we handle the response and resolution.
We use Expo Notifications or direct APNs/FCM integration for push notifications. This includes backend notification triggering, notification preferences per user, deep linking from notification tap, and handling the foreground/background/killed app states correctly. Silent push notifications for background data sync are also something we implement carefully — they require specific entitlements and background modes.
Yes. Offline-first architecture requires planning the data model around local storage (AsyncStorage, SQLite via Expo SQLite, or WatermelonDB for relational data), a sync engine that handles conflict resolution, and queue-based action submission when connectivity is restored. This is not trivial to implement correctly — most offline bugs appear only under intermittent connectivity, which is why this needs engineers who have done it before.
Yes. We integrate Stripe via the Stripe React Native SDK — card collection, Apple Pay, Google Pay, and 3D Secure for SCA compliance. We also handle in-app purchases (IAP) via the App Store and Google Play billing systems for subscription apps. Note that Apple takes a 15–30% commission on IAP — for many apps, using Stripe for web payments and directing users there is a better business decision, and we can help you navigate that.
A focused MVP: 10–18 weeks. A full consumer product with backend: 16–28 weeks. Factor in App Store review time (typically 1–3 days, occasionally longer if Apple requests changes). We plan submission dates into the project timeline so review delays do not catch you off-guard before a planned launch.
