Mobile App Development
Mobile app development is the design and engineering of the iOS and Android product your customers carry in their pocket - the auth screen, the offline sync, the push notification that brings them back, and the store listing that gets them to download it in the first place. We build this on React Native so one codebase powers both platforms, dropping into native Swift or Kotlin modules only where camera-heavy features, AR, or raw performance genuinely require it.
About Mobile App Development
Consumer founders, field-service operators, and product teams extending an existing web platform hire us when a mobile app is not a side project - it is the product, or the part of the product that has to work without a stable connection. We have shipped apps for logistics crews checking jobs offline in the field, marketplaces syncing bookings and payments in real time, and companion apps that mirror a Laravel or Next.js web product's data without duplicating its business rules.
The unglamorous half of mobile work is what usually breaks a launch: token refresh edge cases, background sync conflicts, App Store metadata rejections, and Play Store policy changes that hit at the worst time. We treat store submission and release management as part of the engineering scope, not an afterthought you handle alone after we hand over a build.
What's included
Everything we deliver on this engagement
Product scoping and platform strategy
We define the v1 feature set for iOS and Android from a single React Native codebase, deciding early where native modules earn their complexity cost. Scoping includes device targets, offline requirements, and whether Expo's managed workflow fits or you need the bare workflow for custom native code. You leave this phase with a screen list and a technical plan, not just a mood board.
UI implementation matched to your brand
Screens are built with your design system's spacing, type, and color tokens, with navigation and gestures tuned to feel native on both platforms rather than like a generic cross-platform template. We pay attention to platform conventions - iOS swipe-back, Android hardware back button, safe areas, and keyboard handling - because those small frictions are what make an app feel foreign.
Authentication and secure session handling
Email, OAuth, and biometric login (Face ID, fingerprint) are implemented with tokens stored in the platform keychain, not plain local storage. Session refresh, logout-everywhere, and device-level security are handled so your auth model matches what App Store and Play Store reviewers expect from a production app.
Offline-first data and background sync
For field-service and low-connectivity use cases, we design local caching with conflict resolution rules so data entered offline reconciles cleanly when the device reconnects. This is one of the most commonly underscoped pieces of mobile work - we account for it in the architecture from week one rather than retrofitting it after launch complaints.
Push notifications, deep links, and device integrations
We wire push notifications (via Firebase Cloud Messaging or APNs), deep links that route users to the right in-app screen, and device APIs - camera, maps, payments, contacts - as your product requires. Each integration is tested on real devices, not just simulators, since permissions and hardware behavior diverge there.
Store submission and release management
We prepare App Store and Google Play listings - screenshots, privacy policy links, age ratings, and metadata - and manage the submission and review process end to end. When rejections happen, and they sometimes do even for compliant apps, we handle the resubmission cycle rather than leaving you to interpret Apple's review notes alone.
Our process
How we deliver mobile app development
- 01
Define the MVP scope (weeks 1–2)
We prioritize screens and flows that validate your product hypothesis without overbuilding v1, and lock the offline and integration requirements that shape the architecture.
- 02
Design & prototype (weeks 2–4)
Interactive prototypes on real devices so stakeholders feel navigation, gestures, and performance early - before engineering commits to a screen inventory.
- 03
Build & integrate (weeks 4–10)
React Native development with weekly TestFlight or internal APK builds for feedback, plus backend API work running in parallel where needed.
- 04
Ship to stores (weeks 10–14)
Store compliance, screenshots, privacy policies, and hands-on submission support through App Store and Play Store approval.
Tech stack
Tools we use for mobile app development
React Native
One codebase for iOS and Android with near-native performance, so you are not funding two parallel engineering teams for one product.
TypeScript
Catches integration and data-shape bugs before they reach a device, which matters more on mobile where a bad release ships to app stores, not a hotfixable server.
Expo (select projects)
Speeds up builds, over-the-air updates, and device testing for apps that do not need deep custom native modules.
Firebase
Push notifications, crash reporting, and realtime data for apps that need managed infrastructure without standing up custom servers.
Supabase
Postgres-backed auth and realtime sync when you want an open-source, self-hostable alternative to a fully managed backend.
Node.js & Laravel
Backend API layers for apps that need custom business logic, and the natural fit when the app talks to an existing Laravel or Node web product.
App Store Connect / Play Console
Direct submission, TestFlight distribution, and release management tooling we operate on your behalf through launch.
Who this is for
Use cases that commonly need mobile app development
Consumer app founders validating a mobile-first product
Your product only makes sense as something people carry with them - a habit tracker, a marketplace, a social app. We scope the smallest version that proves the core loop, then build it on a stack that extends past MVP instead of needing a rewrite after traction.
Field-service and logistics teams needing offline reliability
Crews checking jobs, taking photos, or updating status in warehouses and job sites without reliable signal need an app that keeps working offline and syncs cleanly later. We design the local-first data layer as a first-class requirement, not a stretch goal.
SaaS or web products extending into a companion app
Your Laravel or Next.js product already has the business logic and data model. We build a React Native companion app that reuses your existing API and auth rather than duplicating rules across two systems that will drift apart.
Marketplaces and booking apps needing maps, payments, and realtime status
Two-sided apps - deliveries, bookings, on-demand services - need live location, in-app payments, and status updates that feel instant. We integrate maps, Stripe or regional payment providers, and push-based status changes so both sides of the marketplace trust what they see.
Common mistakes
What teams get wrong about mobile app development
"React Native apps feel obviously non-native to users"
That reputation is mostly outdated or the result of skipping platform-specific polish. With attention to gestures, navigation conventions, and native modules where they matter, most users cannot tell - and you get one codebase instead of two.
"We can just wrap our website in a webview"
Webviews pass App Store review inconsistently, feel sluggish, and cannot access push notifications, biometrics, or offline storage properly. If mobile matters enough to be in the store, it is worth building as a real app rather than a wrapper that undersells the product.
"App Store approval is quick if the app works"
Apple's review process rejects apps for metadata issues, privacy disclosure gaps, and policy interpretations that have nothing to do with whether the code runs. We budget review and resubmission time into every launch plan so it does not derail your announcement date.
"Offline support can be added after launch"
Retrofitting offline-first behavior onto an app built assuming constant connectivity usually means rewriting the data layer. If your users will ever be offline, that requirement needs to shape the architecture from the first sprint, not the second release.
Pricing & timeline
What to expect on budget and schedule
A focused MVP with auth, core screens, and one backend integration typically starts at $25k–$45k. Apps that need offline sync, in-app payments, or complex device features - camera processing, live maps, AR - run higher because those integrations require more testing across real devices, not just simulators.
Most MVPs ship in 10–14 weeks including store submission and the review cycle. Larger products with multiple user roles, realtime features, or a companion backend built alongside the app typically run 16–24 weeks, delivered in weekly reviewable increments rather than a single big-bang release.
We quote fixed-scope milestones after a discovery call that pins down platform targets, offline requirements, and integrations - so the estimate reflects your actual feature list, not a generic app template.
FAQ
Common questions about mobile app development
How much does mobile app development cost?
- A focused MVP with auth, core screens, and one backend integration typically starts at $25k–$45k. Apps with offline sync, payments, or complex device features run higher.
How long does it take to build a mobile app?
- Most MVPs ship in 10–14 weeks including store submission. Larger products with multiple roles or realtime features run 16–24 weeks.
Should we build in React Native or fully native Swift/Kotlin?
- We default to React Native for faster delivery and shared logic with your web app. Native modules are added for camera-heavy, AR, or extreme performance cases where the cost of dropping to native code is clearly justified.
Can you connect the app to our existing Laravel or Node.js API?
- Yes. We integrate with Laravel, Node.js, or Supabase backends - reusing your existing auth, business logic, and database rather than duplicating it in a second system that inevitably drifts out of sync.
What happens if Apple or Google rejects our app during review?
- We handle the resubmission cycle directly - reading the rejection reason, adjusting metadata, privacy disclosures, or flagged behavior, and resubmitting. Review timelines are built into the launch plan so a rejection does not blow up your announcement date.
Do you support the app after it launches in the App Store and Play Store?
- Yes. We offer post-launch windows for bug fixes, OS-version compatibility updates, and feature iteration, and can move to a lighter monthly retainer once the app stabilizes and you are shipping less frequently.
