Native iOS development
Built in Swift and SwiftUI for the best performance, deep iOS feature access, and a UI that feels right on iPhone and iPad.
SERVICES · 01Native & cross-platform mobile
Mobile apps that users actually open — and keep open.
From a first MVP to flagship apps with five million plus downloads, we build native iOS and Android apps, cross-platform Flutter and React Native apps, and the mobile backends, analytics, and growth tooling that keep them improving every release.
What we build
Apps that load fast, look right, and survive scale.
Six mobile capabilities we ship every quarter — from first MVP to flagship apps with millions of users.
Native Android development
Kotlin and Jetpack Compose for fast, beautiful Android apps with Material 3 design and edge-to-edge layouts.
Cross-platform with Flutter
One codebase for both stores. Flutter for pixel-perfect custom UIs, React Native for teams already in the React ecosystem.
Mobile backend
REST and GraphQL APIs, auth, push notifications, real-time sync, and admin dashboards — designed for mobile-first workloads.
App Store optimisation
Listing copy, screenshots, keywords, and A/B testing. We help your app actually get found in the store, not just published.
Analytics & growth
Funnel tracking, A/B testing, push campaigns, deep links, and crash reporting — wired in from day one.
Use cases
Apps shipped, downloaded, and rated.
Three mobile builds where the metric that matters — users opening the app every day — actually moved.
Speedy Services on-demand app
Cross-platform Flutter app for an on-demand home-services platform — booking, real-time tracking, payments, and worker dispatch across 30+ cities.

How we work
From idea to App Store in six steps.
Most clients start with a 2-week scoping sprint — fixed-price discovery that produces wireframes, architecture, and a confident estimate.

Discovery & scope
Free 30-min call. We map the user journey, must-have features, and target platforms.
02
UI / UX design
Wireframes, prototypes, and clickable Figma files reviewed weekly with you.
03
Sprint plan
Two-week sprint roadmap with weekly demos and a fixed-price quote.
04
Build
Mobile + backend in parallel, with continuous integration and TestFlight / internal track builds.
05
QA & submit

Frequently asked
Mobile app development questions.
How long does mobile app development take?
A mobile app MVP at Appsmediaz takes 8 to 14 weeks from kickoff to App Store launch. Simple apps with 5 to 10 screens ship in 8 to 10 weeks; feature-rich apps with custom integrations, payments, and admin dashboards take 12 to 18 weeks. We work in two-week sprints with weekly demos.
How much does a mobile app cost?
A typical mobile app build at Appsmediaz starts at around $8,000 for a single-platform MVP and scales to $25,000 to $80,000 for cross-platform apps with backend, admin panel, and integrations. Final price depends on platforms (iOS, Android, or both), feature scope, integrations, and timeline.
Should I choose native or cross-platform?
Native (Swift, Kotlin) is best when you need top performance, deep OS integration, or platform-specific UX (think AR, complex animations, hardware access). Cross-platform (Flutter, React Native) is best when you need to ship to both iOS and Android with one team and codebase. We'll recommend honestly based on your product, not our preferences.
Do you submit the app to the App Store and Play Store?
Yes. We handle App Store Connect setup, Google Play Console submission, app store optimisation (ASO), screenshot design, listing copy, and post-launch troubleshooting. Most clients keep ownership of the developer accounts; we operate them on your behalf.
What happens after the app launches?
We offer post-launch support contracts covering bug fixes, OS update compatibility, analytics review, and small feature additions. Most clients also continue a Delivery Pod engagement to ship new features in two-week sprints.
