Should we build native iOS/Android or use React Native or Flutter?

It depends on your requirements, not on what's easier to staff. Native (Swift/Kotlin) makes sense when you need deep hardware integration (Bluetooth, camera APIs, ARKit, complex animations) or when your app's primary differentiator is platform feel. React Native and Flutter are strong choices for products with shared business logic across platforms, teams that need to iterate quickly, and apps where the UI is standard rather than bespoke. We assess your use case and give you an honest recommendation with tradeoffs before scoping, not a default answer.

How long does it take to build a mobile app, and what does it cost?

A focused MVP with core flows, backend integration, and store submission falls in our MVP / Prototype range: 4 to 8 weeks with a dedicated two-to-three engineer team. Full-featured consumer apps are Production Application builds of 3 to 5 months, and enterprise apps with complex backends and third-party integrations can run 6 to 12 months. We price on monthly team cost and give you a written scope with timeline before you commit. For typical budgets and timelines, see our project cost estimator at codieshub.com/project-cost-estimation. We don't do fixed-bid on complex mobile projects; scope changes too much to promise a number that holds.

Can you take over an existing mobile codebase?

Yes, and we do it regularly. Our process starts with a two-week technical assessment of the existing codebase (architecture, test coverage, dependency health, known issues) before we scope the takeover. We're honest about what we find. Some codebases are worth continuing; some are cheaper to rebuild. You get a written assessment with our recommendation and the reasoning behind it before any development starts.

How do you handle OS version updates and Apple/Google policy changes?

Both App Store and Google Play enforce annual minimum SDK requirements, and Apple policy changes (App Tracking Transparency, privacy nutrition labels, data deletion requirements) can require sprint-cycle updates. For clients on ongoing engagements, we monitor policy change announcements and plan compliance updates in the sprint before the deadline, not after the platform rejects an update. For new builds, we build to the current requirements from day one so there's no compliance debt at launch.

Do you integrate with third-party backends, payment processors, and analytics platforms?

Yes, third-party integration is standard work in every mobile engagement. Common integrations we handle include Stripe and Braintree for payments, Firebase and Amplitude for analytics and crash reporting, Twilio and OneSignal for push notifications and messaging, Plaid for financial data, and REST or GraphQL APIs against any backend we or your team built. We document all integrations and their authentication patterns so your team can maintain them.

Mobile App Development Services

Should you build a native or cross-platform mobile app?

Choose native Swift or Kotlin when the app depends on deep platform features or peak performance, and React Native or Flutter when one codebase across iOS and Android serves the product well. Codieshub recommends based on your use case, not staffing cost, and has published 80+ mobile apps with a 4.8/5 average store rating.

How we approach Mobile App Development

Mobile is where most products live or die, not because app stores are hard to publish on, but because the quality bar users hold mobile to is merciless. An app that's slow to open, drops state, or looks fractionally off on a flagship device gets one-star reviewed and abandoned. Building mobile well means senior engineers who understand the platform internals, not just a React Native bootcamp graduate wrapping a web app in a WebView.

Codieshub has been building production iOS and Android applications since 2012 (native Swift, Kotlin, and cross-platform React Native and Flutter) for clients in fintech, healthcare, logistics, and consumer. Our senior engineers work hours that overlap your US or UK day, which matters when you need live collaboration on sprint reviews, QA sessions on physical device labs, and design handoff calls that don't require someone on your team to be awake at midnight.

We build end to end: product scoping, UX architecture, native development, backend integration, App Store and Play Store submission, and post-launch live ops. The same senior engineers who design your data layer ship the UI and tune the performance. No silos, no handoff gaps.

The challenge

Mobile projects fail for one of three reasons: a cross-platform shortcut that produces something that feels like a website rather than an app; a junior team that can build the happy path but can't handle offline sync, push notification edge cases, or platform OS upgrades; or an agency that ships and disappears, leaving a codebase nobody on your team understands. All three kill retention before the first month.

Our approach

Codieshub mobile teams are senior, stack-matched, and dedicated to your engagement. We assess your requirements early and recommend native or cross-platform based on your use case, not what's cheapest to staff. Engineers handle the full stack: UI to API integration to background processing to analytics instrumentation. We build with your App Store guidelines in mind from day one so certification isn't a scramble at the end.

The outcome

An app built to current store guidelines, performing at target on mid-range Android devices, and structured to absorb OS updates without a scramble. Clients come back for feature releases and major version updates with the same team, because knowledge continuity on mobile is what separates a one-time build from a sustainable product.

Why Codieshub

Six reasons teams stay past the pilot.

The shortlist we get asked about on every call, what actually separates Codieshub from a dev shop.

Native iOS and Android
Swift, Kotlin, and platform-native APIs: real native development for clients whose UX, performance, or hardware integration requirements demand it.
React Native and Flutter
Cross-platform when the use case fits: shared logic, consistent UI, and a single codebase maintained by engineers who've shipped commercial apps in both frameworks.
Offline-first and sync
Conflict resolution, local storage, background sync, and graceful degradation, mobile features that only senior engineers with real production experience build correctly.
App Store compliance baked in
Privacy manifests, ATT prompts, App Review guidelines, and Play Protect compliance handled from the first sprint, not bolted on before submission.
Instrumentation and analytics
Event tracking, funnel instrumentation, crash reporting, and A/B test hooks integrated from the start so your product team has data on day one post-launch.
Launch-ready delivery
Store assets, metadata, App Store Optimization copy, and beta testing via TestFlight and Firebase, everything needed to publish, not just to build.
