Mobile App Development Services
Mobile apps backed by an API that's built to last, not just launch.

Mobile app development is building an iOS and Android application, typically alongside the backend API that powers it. DuCodes builds both together — usually with React Native or Flutter for cross-platform apps — so authentication, data sync, and push notifications are designed as one system.
A mobile app is only as good as the backend behind it. We build both sides together — the app itself (usually React Native or Flutter for cross-platform reach) and the API that powers it, so authentication, data sync, and push notifications are designed as one system instead of two separately-built halves that don't quite fit.
For most business apps, cross-platform development gets you to both app stores faster without a meaningful quality tradeoff. We'll recommend fully native development instead when the app genuinely needs it — heavy use of device-specific APIs, for example.
Why work with DuCodes on this
Backend and app built together
The API is designed around what the app actually needs, not adapted after the fact from an existing web backend.
Cross-platform by default, native when it matters
We recommend the approach that fits your actual requirements and budget, not the one that's most interesting to build.
Offline and sync handled properly
Apps that need to work with unreliable connectivity get designed for that from the start, not patched in later.
App store submission included
We handle the App Store and Google Play submission process, including the parts that trip up first-time submitters.
How we work
Discovery & platform decision
Native vs. cross-platform, offline requirements, and core user flows.
API & data design
Backend architecture built around the app's actual data and sync needs.
UI/UX design
Platform-appropriate design — an app that follows iOS/Android conventions feels native even when cross-platform.
Development
App and API built in parallel, tested together throughout.
Store submission & launch
App Store / Play Store review process managed end to end.
Post-launch support
OS updates and store policy changes require ongoing maintenance — we plan for that, not just the initial release.
