Frequently asked questions

Do you build separate apps for iOS and Android?

In most projects we ship store-quality apps for both platforms from a single React Native or Flutter codebase. Where deep platform features or top performance matter, we build natively in Swift and Kotlin; we make that choice together during discovery.

How long does app development take, and what drives the cost?

Time and budget depend on the number of screens and user roles, integrations such as payments or maps, offline requirements and whether you launch on both platforms at once. At the end of discovery we put scope, timeline and budget in writing, and during development you see progress in a working app every week.

Do you publish the app on the App Store and Google Play?

Yes. Store submissions, the review process and automated releases through a CI/CD pipeline are part of delivery. The app is published under your own developer accounts, so the app and its store listings belong to you.

Do you maintain the app after launch?

Yes. We offer ongoing maintenance: monitoring, crash reporting, bug fixes, updates for new iOS and Android versions and new features. The code, documentation and release steps stay with you, and if you ever continue with another team, they get a project they can take over.
