Most apps are deleted within a week of install. The ones that survive are fast, reliable, and useful offline — qualities that are engineered in, not patched in. We build native and cross-platform apps for iOS and Android that people keep. Fixed scope. Fixed price. You own everything on handoff.
A mobile app lives in a harsher world than a web app: flaky networks, aggressive OS memory management, two review processes with their own rules, and users who uninstall at the first spinner. We engineer for that world — offline-first data where it matters, cold-start budgets, and crash-free-session targets set before the first sprint.
On cross-platform builds we work in React Native, sharing one codebase across iOS and Android without giving up native performance where it counts — navigation, gestures, camera, payments. When a product genuinely needs full native, we say so up front rather than forcing a framework to do what it shouldn’t.
We have shipped a complete two-sided marketplace — customer app, provider app, and backend — to both stores in 14 weeks. We wrote up exactly how, including the cut list, because the decisions that make a deadline survivable are the same ones that make an app maintainable.
One team shipping to both stores — provisioning, review submissions, staged rollouts, and the store-specific rules handled for you.
React Native with native modules where performance demands it — one codebase, two first-class apps.
Local storage, sync, and conflict handling designed for real-world networks — the app works on the train, not just on office Wi-Fi.
Notifications, deep links, and SMS flows that bring users back without burning their goodwill.
In-app payments, wallets, and sign-in built on platform-approved patterns — through review the first time.
The server side ships with the app: versioned APIs, admin tooling, and analytics your team can actually use.

Customer app, provider app, and backend — a full two-sided on-demand marketplace shipped to the App Store and Google Play in 14 weeks.

Read the Devon Ave story →It depends on what the app does. For most business and marketplace apps, React Native delivers two first-class apps from one codebase at a meaningfully lower cost. For apps built around heavy real-time graphics or deep hardware access, native is the honest answer. We recommend in writing, with the trade-offs, before you commit.
A focused single-purpose app can ship in 8 to 12 weeks; we have shipped a complete two-sided marketplace to both stores in 14. The written SOW gives you a date that includes store review time, not just development time.
Yes — provisioning, listings, review submissions, rejection responses, and staged rollouts are part of the build, not an extra. Both store accounts are created in your name so you own the listings from day one.
Yes. Almost every serious app is half server: APIs, accounts, admin tools, notifications. We ship the whole system as one fixed-scope project so there is no seam between an app vendor and a backend vendor.
Every launch includes 30 days of post-launch support covering crash triage and store issues. After that, you can maintain it with the documentation we hand over or keep us on a monthly product partnership.
