Android & iOS apps, built with Flutter
We design and build cross-platform mobile apps for Android and iOS from a single Flutter codebase - with the backend, authentication, and integrations handled by the same team.
What this service covers
XCoder Software Agency builds mobile applications end to end: product scoping, UI/UX design, development, testing, store-ready builds, and post-launch support. We work primarily with Flutter and FlutterFlow, which lets one codebase ship native-feeling apps on both Android and iOS - faster to build, cheaper to maintain, and consistent across devices.
On the backend we typically pair apps with Firebase or Supabase for authentication, real-time databases, cloud storage, and push-ready infrastructure, and connect payment gateways and third-party services through our API integration work. Recent builds include an AI-powered wellness app, a fitness tracker, and a school portal used by teachers and students every day.
Everything the service delivers
Product scoping
Requirements, screens, and features mapped before code starts, so the quote and timeline hold.
App UI/UX design
Custom Figma designs - not templates - turned into pixel-accurate Flutter interfaces.
Flutter development
Cross-platform Android & iOS development from one clean, maintainable Dart codebase.
Backend & auth
Firebase or Supabase backends with secure authentication, databases, and cloud storage.
Integrations
Payment gateways, REST APIs, and third-party services wired in and tested.
Launch & support
Store-ready builds, deployment help, and one month of free post-launch maintenance.
The same process as every XCoder project
Discover
Requirements, technical audits, and scoping so nothing gets built twice.
Design
Architecture decisions and UI/UX prototyping validated before code starts.
Develop
Agile sprints, code review, and continuous QA keep quality high.
Test & Review
Full QA, cross-device testing, and a review round with you before anything goes live.
Deploy & Scale
Launch, monitoring, and ongoing optimization once you're live.

Common questions about mobile app development
Yes. We build with Flutter, so one codebase runs on both Android and iOS with a native feel - you don't pay for two separate apps.
Simple apps take around 20 working days and full-functional apps 30–40 working days, depending on scope. Fast-delivery options are available at a 15% surcharge.
We work on simple fixed-quote terms: 50% advance to start the project and 50% before final delivery. Full ownership of the code and design transfers to you on final payment, and every project includes one month of free maintenance.
