Your app is written once in React Native and TypeScript. The same code builds a native iOS app and a native Android app, with Swift or Kotlin modules only where a feature needs the phone's hardware.
Mobile app development
Mobile app development for iOS and Android, built once and shipped properly.
Cross-platform apps with native performance, the backend and admin they need, and App Store and Google Play submission handled - on a fixed scope with a working build on your phone every week.

A mobile app earns its place when people use it repeatedly, on the move, or with the phone's hardware - camera, location, push notifications, offline access. Field crews, members, patients and repeat customers are good reasons. "We should have an app" usually isn't.
We build with React Native, so iOS and Android share one codebase and one budget, dropping into native Swift or Kotlin modules when a feature needs it. Every app ships with the backend, admin panel and analytics it needs to be run as a product, not a brochure.
See it working
One codebase, two stores, always in sync.
Follow one app from shared React Native code through App Store and Google Play review to iPhone and Android, then watch both phones work from one backend. Scroll to step through it, or take the phones offline and send a push yourself.
Live system
Every week a new build lands on your phone through TestFlight and Google Play testing tracks. At launch we prepare the listings and handle review, planning for the usual rejections: account deletion, permission prompts and demo logins.
iPhone and Android share one API and PostgreSQL database, so accounts, bookings and payments (Stripe, Apple Pay and Google Pay) stay in sync across devices. The same backend runs the admin panel and analytics you manage it with.
When something needs attention, such as a new job, a booking reminder or an order update, your backend sends one notification through Firebase and it lands on iPhone and Android together. Tapping it opens the right screen.
Field apps keep working in a basement or on a roof. Checklists, photos and signatures are saved in a queue on the phone, and the moment the connection returns they sync to your backend in order.
What we build
Mobile App Development: what it looks like in practice.
Customer & member apps
Accounts, bookings, loyalty, payments and push notifications that bring people back.
Field & operations apps
Offline-first apps for crews and inspectors: checklists, photos, signatures and GPS, syncing when signal returns.
Companion apps for your platform
A mobile front end for your existing web app or SaaS, sharing the same API and permissions.
Marketplace & booking apps
Two-sided apps with search, scheduling, messaging and payments between users and providers.
App MVPs for founders
The smallest version that proves demand - built on a foundation that doesn't need a rewrite. See MVP development.
Rescue & rebuilds
Take over an app that's crashing, stuck in review or impossible to update - audit first, then fix or rebuild.
Pricing
What it costs, in real numbers.
Mobile app budgets are driven by the number of screens and user types, offline and real-time needs, and the backend behind the app. Typical price ranges:
App MVP (iOS + Android)
From $15k
Core flow, accounts, backend API, admin panel and store submission for both platforms.
8–12 weeks
Business app
$35k–$90k
Multiple user roles, payments, notifications, integrations with your CRM or operations systems.
3–5 months
Complex app
$90k+
Real-time features, offline sync, device hardware, marketplaces or heavy integrations. Delivered in phases.
5+ months, phased
Budget for Apple's Developer Program ($99/year) and Google Play's one-time $25 registration, plus backend hosting and any SMS or push services at their published rates. We'll list every recurring cost in your proposal.

Is this right for you?
An honest fit check.
A strong fit if…
- Users will open it weekly or more, or need it on the move.
- You need the camera, GPS, push notifications or offline access.
- You have (or will build) a backend and admin to run it as a product.
Probably not the right move if…
- People will use it once or twice - a fast [web app](/services/web-app-development) is cheaper and has no install friction.
- The app is mainly a brochure for your website.
Expert notes
What we'd tell you on the first call.
React Native vs. Flutter vs. fully native
For most business apps, one cross-platform codebase gives you both stores for close to the price of one, with performance users can't tell apart. We go fully native only when an app lives on heavy graphics, advanced Bluetooth or platform-specific hardware - and we'll explain the trade-off in writing before you commit.
Getting through App Store review
Apps get rejected for predictable reasons: missing account deletion, vague permission prompts, broken demo logins, or payments that break store rules. We plan for those in the scope, not after the rejection email.

FAQ
Mobile App Development: questions buyers ask.
How much does it cost to build an app?
Our app MVPs for iOS and Android start around $15k, business apps with payments and integrations usually run $35k–$90k, and complex apps start around $90k. You get a fixed price after discovery.
Do you build for both iOS and Android?
Yes - from one React Native codebase, so both platforms ship together and stay in sync.
Will you publish the app to the App Store and Google Play?
Yes. We prepare the listings, handle review submission and publish under your own developer accounts so you own the apps.
How long does app development take?
An MVP usually takes 8–12 weeks; business apps 3–5 months. You get a new test build on your phone every week.
Can you update an app someone else built?
Often. We start with a code audit so you know whether it's worth fixing or cheaper to rebuild.
What does it cost to maintain an app?
Plan on roughly 15–20% of the build cost per year for OS updates, store requirement changes, security patches and small improvements.
