Mobile App Development

Our mobile app development services take an app from first prototype to the App Store and Google Play, and keep it healthy after launch. Most apps share one React Native codebase across iOS and Android, then drop to native Swift or Kotlin where performance, hardware access, or platform feel demand it. Offline sync, push notifications, payments, and release management are planned in from the start.

Start a project

An app gets one chance on a user's home screen

Mobile users are unforgiving. An app that stutters on scroll, loses a draft on a weak signal, or asks for every permission on first launch gets uninstalled, and the store rating follows. Most of those problems trace back to early decisions: the wrong cross-platform approach, sync added late, or a release process that depends on one person's laptop.

We build iOS and Android apps that feel native on both platforms. Most share a single React Native codebase, with Swift or Kotlin modules where performance or hardware access needs them. Offline behavior, push notifications, subscriptions, and automated store releases are designed in from the first sprint, so launch day is routine and so is every update after it.

What's included

iOS and Android apps from one React Native codebase, with native Swift and Kotlin where it matters, and releases that ship on schedule.

Cross-platform app development with React Native
Native iOS (Swift) and Android (Kotlin) development
Offline-first data and background sync
Push notifications, deep links, and in-app purchases
App Store and Google Play release management
Crash monitoring, analytics, and post-launch updates

Four decisions that separate a five-star app from an uninstall

Each is cheap to get right at the start and expensive to change once the app has users and reviews.

01

Right tool, per feature

React Native for most screens, native code for the camera, Bluetooth, heavy animation, or anything that has to feel perfect. We decide feature by feature, not on ideology.

02

Offline by default

Phones lose signal in elevators and on trains. Data is stored on the device and synced in the background, so the app works first and catches up later, without lost drafts or duplicate orders.

03

Boring releases

Builds, signing, store metadata, and staged rollouts run from CI. Any engineer can ship a release, and a bad one can be halted while it has reached a small share of users instead of all of them.

04

Measured on real devices

Crash reporting, performance traces, and product analytics from the first beta, so decisions rest on what people do on their actual phones, not on the simulator.

Mobile app development services for iOS and Android

Six types of mobile work we deliver, from getting a first MVP into the stores to rescuing an app with a falling rating.

Cross-platform apps

One React Native codebase for iOS and Android that looks and behaves like a native app on each, so you ship to both stores at once and run one team instead of two.

  • React Native and Expo
  • Platform-specific navigation and UI
  • Business logic shared with your web app

Native iOS & Android

Swift and Kotlin where the product lives on the hardware: camera and AR features, Bluetooth devices, health data, or graphics that need every frame.

  • Swift and SwiftUI on iOS
  • Kotlin and Jetpack Compose on Android
  • Native modules inside React Native apps

Offline-first & sync

Apps for field teams, travel, and anywhere coverage is patchy. Local storage, background sync, and conflict handling, so nothing a user enters is lost.

  • On-device database and caching
  • Background sync with conflict resolution
  • Graceful behavior on poor connections

Payments & subscriptions

In-app purchases, subscriptions, and payments that follow Apple's and Google's rules, with entitlements kept in step across devices and your backend.

  • In-app purchases and subscriptions
  • Paywall and free-trial experiments
  • Receipt validation and entitlements

Engagement & notifications

Push notifications, deep links, and in-app messages that bring people back for a reason, with permissions requested at the moment they make sense.

  • Segmented push notifications
  • Deep links and universal links
  • Permission prompts timed to intent

Store releases & support

Store listings, review guidelines, staged rollouts, and the major OS updates Apple and Google ship every year, handled so your app keeps working and keeps its rating.

  • App Store and Google Play submissions
  • Staged rollouts with fast rollback
  • Annual iOS and Android upgrade work

Our app development process, from prototype to the app stores

A first version usually reaches the stores in ten to fourteen weeks. You have a test build on your own phone within the first month, and a new one every two weeks after that.

Stage 01

2 weeks

Discovery & prototype

We map the core user journeys, decide cross-platform or native feature by feature, and test a clickable prototype with real users before any production code is written.

  • User journeys and feature scope
  • Clickable prototype tested with users
  • Architecture and fixed quote
Stage 02

2–3 weeks

Foundations & first build

Navigation, sign-in, the backend API, crash reporting, and the automated release pipeline, with one complete journey running on your phone through TestFlight or Play testing.

  • Installable test build on iOS and Android
  • CI pipeline with signing and distribution
  • Analytics and crash reporting live
Stage 03

5–8 weeks

Build & beta

Features land in two-week releases to a growing group of beta testers. We test on real devices across screen sizes and OS versions, and tune speed and battery use before launch.

  • Feature-complete beta
  • Device and OS test matrix
  • Performance and accessibility review
Stage 04

Ongoing

Launch & iterate

Store listings, review submissions, and a staged rollout, then a steady rhythm of updates guided by crash data, reviews, and product analytics.

  • Live on the App Store and Google Play
  • Staged rollout with monitoring
  • Post-launch roadmap and support plan

What a well-built mobile app gives you

One team shipping to iOS and Android at the same time

An app that keeps working on a weak or missing connection

Releases any engineer can ship, and any bad build halted mid-rollout

Ratings and retention backed by real-device performance data

What we build it with

The tools we reach for on Mobile Apps work, picked for the problem in front of us and for the team who inherits the code.

01

Cross-platform

One codebase, native feel on both stores

  • React Native
  • Expo
  • TypeScript
  • Flutter
02

Native

Dropped to platform code where it earns its keep

  • Swift
  • Kotlin
  • Jetpack Compose
  • Xcode
03

Services

Sync, auth and subscriptions

  • Firebase
  • Supabase
  • GraphQL
  • RevenueCat
04

Release and quality

Store submissions that are boring on purpose

  • Fastlane
  • App Store
  • Google Play
  • Sentry

Mobile app development questions we hear most

  • The cost of a mobile app depends mostly on the number of screens and user journeys, the backend it needs, and hardware features such as the camera, Bluetooth, or payments. A focused MVP with one core journey costs far less than a marketplace with two types of user and real-time features. Our two-week discovery ends with a tested prototype and a fixed quote for a defined first release, so you decide with real numbers.
