Common Questions About App Development
Clear answers to help you navigate mobile project planning with confidence.
Why Flutter instead of separate native apps?
Flutter compiles directly to native ARM machine code on both iOS and Android, providing identical 60fps performance to native Swift and Kotlin while saving 40-50% in development time and long-term maintenance overhead.
What is needed to publish on the App Store and Google Play?
You will need an Apple Developer Account ($99/year + taxes) and a Google Play Console Account ($25 one-time + taxes). We guide you through registration, set up API keys, prepare required screenshots, and submit the builds on your behalf.
Can the app work without an internet connection?
Yes. We architect offline-first capabilities using local SQLite or Hive databases. Users can view loaded information, submit drafts, or interact with core features; data automatically synchronizes as soon as a network connection is restored.
Who owns the code and intellectual property?
You own 100% of the source code, design assets, and intellectual property. Everything is transferred to your organization's private GitHub repository upon milestone completion.
