Process

How We Build Your App

A proven 5-step process that de-risks your project and delivers on time.

01

Discovery

We understand your users, market and goals. Wireframes, user flows and technical architecture defined upfront before a single line of code is written.

02

Design

UI/UX design with prototypes you can test. Iterate fast, validate with real users and lock the experience before development begins.

03

Development

Agile sprints with weekly builds. Backend, frontend and API development run in parallel for speed. You see working software every sprint.

04

Testing

QA across devices, OS versions and edge cases. Performance, security and usability testing included. Every release is production-ready.

FAQs

Frequently Asked Questions

What is cross-platform app development?

Cross-platform development uses a single codebase (React Native or Flutter) to build apps for both iOS and Android simultaneously, saving 40-50% development time.

How is the quality compared to native apps?

Modern cross-platform frameworks deliver near-native performance. React Native and Flutter both access device APIs directly and render with native components.

Which framework do you recommend?

Flutter is ideal for pixel-perfect UIs and faster prototyping. React Native is better for apps needing extensive native module integration. We help you choose.

Can you add native features later?

Yes. Both frameworks support native modules. You can write platform-specific code where needed and share the rest across platforms.

How much does cross-platform development cost?

A cross-platform app typically costs 30-40% less than building two separate native apps. Basic apps start at $15,000. Enterprise apps $40,000 - $120,000+.

When should I choose cross-platform over native?

Choose cross-platform when you need both stores with one team and a tighter budget, and your app does not depend on deep platform-specific hardware features.

Does cross-platform feel native?

With React Native and Flutter, yes. Users cannot tell the difference in most apps, and we tune platform-specific behaviors.

Can I move to native later?

Yes. We architect with clean boundaries so critical modules can be rewritten natively without a full rewrite.

How much do I save with cross-platform?

Roughly 30-40% versus two separate native codebases, because you build, test and maintain one codebase.
