Direct Answer Architecture • 6 Verified FAQs

Frequently Asked Questions — App Development

Q01

Do you build for both iOS (iPhone) and Android?

Yes. Our Standard ($1,499) and Premium ($3,499) plans use modern cross-platform architecture (React Native / Expo or Flutter) to compile native iOS and Android binaries from a single maintainable codebase. Our Basic ($499) plan covers a single-platform starter build.

Q02

Who owns the mobile app source code?

You own 100% of the source code, assets, and database schemas. We hand off the complete repository upon completion.

Q03

Do you help publish the app to the Apple App Store and Google Play Store?

Yes. In Standard and Premium tiers, we prepare your production build binaries (.ipa and .aab), configure store signing certificates, and guide submission inside your Apple Developer and Google Play Console accounts.

Q04

Why do I need my own Apple Developer and Google Play accounts?

Apple and Google require apps to be published under the legal brand owner's developer account. Publishing under your own account ensures you control your user base, payments, and store listing permanently.

Q05

Can my mobile app connect to AI models like OpenAI, Claude, or Voice AI?

Yes. In our Premium tier, we integrate secure server-proxied AI APIs for in-app chat assistants, voice transcription, image recognition, or personalized recommendations.

Q06

What happens after the 7, 30, or 60 days of included post-launch support?

Because you own the clean source code, your internal team can maintain it, or you can opt into an optional monthly maintenance & feature sprint plan with Tiyan Digital.
