FAQ

Questions teams ask before hiring.

Native or cross-platform?

Cross-platform (React Native or Flutter) suits most business apps and saves time; native Swift and Kotlin is better for heavy graphics, complex device features or very high performance. We recommend one after hearing your plans.

Do you build the back end too?

Yes. APIs, databases and admin panels behind the app can be built by the same team.

Do you publish to the stores?

Yes. We prepare listings, submit to the App Store and Play Store, and handle review feedback.

Who owns the code?

You do. Code is written in your repositories or handed over in full, and intellectual property transfers to you as set out in the agreement we sign.

How much does it cost to hire mobile app developers?

It depends on the model (hourly, dedicated or fixed-scope) and the work involved. After a free 30-minute call we send a written proposal with the cost, so you know the price before anything starts.

Can we start small?

Yes. Many clients start with a short hourly task or an audit, then move to a dedicated engineer or a fixed project once they have seen how we work.
