Cross-PlatformMobileAppDevelopmentServices
High-performance apps for iOS, Android, and web — one codebase, every platform.
Overview
We build mobile applications from a single, scalable codebase that ships to iOS, Android, and the web without the cost of three separate teams. TheCraftSync’s mobile practice has shipped apps handling hundreds of thousands of concurrent users, so performance and stability are built in, not patched on after launch. Using Flutter and React Native, we deliver native-quality performance while keeping one engineering team, one codebase, and one release cycle — the same approach top cross-platform development companies use for enterprise-scale mobile products.
What We Offer
1 Cross-Platform App Development
Single-codebase apps built with frameworks like Flutter, React Native, or Ionic that run natively on iOS and Android.
2 Native iOS & Android Applications
Fully native builds where platform-specific performance or APIs demand it.
3 Progressive Web Applications (PWA)
App-like experiences that run in the browser and install directly, without an app-store dependency.
4 Mobile Backend & API Services
Purpose-built backend services and APIs that support offline sync, push notifications, and real-time data.
5 App Performance & Optimization
Profiling and tuning for load time, battery usage, and smooth interactions at scale.
6 App Security & Compliance
Secure authentication, data encryption, and store-compliance reviews before submission.

Frequently Asked Questions
For most products, cross-platform delivers 80–90% of native performance at a fraction of the maintenance cost. We recommend native only when the app depends heavily on platform-specific hardware or APIs.
Yes, we regularly take over apps built by other teams — we start with a codebase and architecture audit before making changes.
Yes, including compliance review, store listing optimization, and managing the review process.
We load-test backend services ahead of launch and build with offline-first, efficient data-sync patterns from the start.
Both deliver strong cross-platform performance. We typically recommend Flutter for UI-heavy, highly custom designs and React Native when the team wants to share more code with an existing React web app.
Yes — our team has delivered mobile platforms handling 300,000+ concurrent users, with the backend and architecture load-tested ahead of launch.
