FAQs
Frequently asked questions.
Anything else about mobile app development? Ask us directly. A real engineer reads every message.
Should we build native or cross-platform?
Cross-platform (Flutter or React Native) suits most apps and saves budget. We recommend native when an app needs very specific device features or the highest performance.
How long does it take to build an app?
A focused first version often takes three to five months. We give you a firm timeline after discovery.
How much does a mobile app cost?
It depends on features, platforms and integrations. After a short discovery we share a clear estimate and options to fit your budget.
Will you publish the app to the stores?
Yes. We prepare store listings, handle submissions and respond to review feedback.
Who owns the source code?
You do. All code, designs and assets are yours under contract.
Do you maintain apps after launch?
Yes. We offer monitoring, bug fixes, OS updates and new features as an ongoing service.
Can you take over an app another team built?
Yes. We review the code first, then agree a plan to fix, improve or rebuild it.
