Cross-platform App Development with Flutter & React Native

Most businesses need their app on both Android and iOS. Cross-platform development with Flutter or React Native lets one team ship both from a single codebase, cutting cost and time to market while keeping the app fast and native-feeling.

What this covers

Cross-platform Applications

Typical timeline

An MVP app typically ships in 10–16 weeks; larger apps are delivered in phases.

Who it is for

Who our Cross-platform App Development service is for

We choose the framework that fits your team and product: Flutter for pixel-perfect custom interfaces, React Native when you want to share skills and code with a React web app. Native modules are written wherever a feature needs platform-specific code.

Discuss your requirement

01
Startups launching on Android and iOS at the same time
02
Businesses replacing two separately maintained apps
03
Companies with a React web team wanting to reuse skills
04
Enterprises needing consistent apps across devices

Capabilities

What is included in Cross-platform App Development

Flutter apps

High-performance apps with custom UI and smooth animations from one Dart codebase.

React Native apps

Apps built with React Native and Expo, sharing logic and skills with your web products.

Native modules

Platform-specific code for payments, hardware and SDKs that have no cross-platform plugin.

Offline sync & real-time

Local databases, background sync and real-time updates with WebSockets or Firebase.

Over-the-air updates

Instant fixes and content updates without waiting for store review, where store policies allow.

Both-store launch

Coordinated Play Store and App Store releases with shared analytics and crash reporting.

Choose how we work together

Fixed-scope project

A discovery workshop produces a written scope, architecture and milestone plan with a fixed price before any build commitment.

Most chosen

Dedicated product team

A cross-functional squad (PM, engineers, QA, DevOps) working in two-week sprints on your roadmap, billed monthly.

Support & evolution retainer

SLA-backed maintenance, security patching and a monthly allocation of enhancement hours after go-live.

How pricing works: Every project is priced after a free discovery call: you receive a written scope with milestones and a fixed quote, so there are no surprises mid-way.

FAQs

Cross-platform App Development: frequently asked questions

Flutter or React Native: which should we choose?

Flutter excels at custom, animation-rich interfaces with consistent rendering on every device. React Native suits teams with React skills or a React web app to share code with. Both are production-proven; we recommend based on your product and team.

Is a cross-platform app slower than a native app?

For most business and consumer apps users cannot tell the difference. Very graphics-heavy or hardware-intensive apps may still benefit from native development, and we will tell you if yours is one of them.

How much can we save compared with two native apps?

Savings depend on the app, but sharing one codebase usually reduces development and maintenance effort substantially because features, fixes and tests are written once.
