FAQ
Mobile app development FAQs
Do you build for both iOS and Android?
Yes. We usually build one cross-platform codebase in Flutter or React Native that ships to both stores, which cuts cost and time compared with two native apps.
How long does an app take?
A focused MVP typically takes 8-12 weeks. Larger apps with complex backends take longer; we give a fixed timeline after discovery.
Can you add AI features to my app?
Yes. We integrate AI chat assistants, smart search, recommendations, voice input and image recognition using leading AI APIs.
Will you publish the app to the stores?
Yes. We prepare listings, screenshots and compliance details and handle submission to the Apple App Store and Google Play.
Who owns the source code?
You do. Full source code, accounts and documentation are handed over at the end of the project.
