Can you handle App Store and Play Store submission?

Yes. We manage the full submission process, including compliance review, metadata, and app store optimization.

What are typical project timelines?

Most mobile app engagements run 10-18 weeks depending on platform coverage and complexity, with a testable build typically ready within 6-8 weeks.

Do you support offline functionality?

Yes. We design offline-first architectures with local data storage and conflict-resolution sync strategies for apps that need to work without connectivity.

Do you provide ongoing support after launch?

Every engagement includes a post-launch support plan covering OS compatibility updates, crash monitoring, and new feature development.

Expert Engineers

We build mobile apps that feel native, work offline, and keep performing long after they clear App Store review.

We build with native Swift and Kotlin or cross-platform React Native, choosing the right approach for your product and team, then support you through launch, updates, and every OS release after that. For the backend and API work behind the app, see our custom software development page.

Still have questions? Reach out to our mobile team directly.

It depends on your requirements. We recommend native for performance-critical or deeply platform-integrated apps, and React Native when speed-to-market across both platforms matters most.
