Service FAQ

Frequently Asked Questions About Mobile Application Development

Q1.Should we build our mobile app with Flutter, Kotlin Multiplatform, or pure Native?

If you need rapid delivery across Android and iOS with a shared UI, Flutter is an excellent choice. If you want native SwiftUI and Jetpack Compose interfaces while sharing business logic and networking, Kotlin Multiplatform (KMP) is ideal. For apps requiring deep OS hardware integration or low-level media processing, pure native Kotlin and Swift remain the gold standard.

Q2.Do you handle Google Play Store and Apple App Store submission and compliance?

Yes. As a verified mobile publisher, AppQor manages the entire store release pipeline—including target SDK compliance, Google Play Data Safety forms, Apple Privacy Manifests, app-ads.txt verification, Digital Asset Links (assetlinks.json), and mandatory user account deletion endpoints.

Q3.Can our mobile app work offline without an active internet connection?

Absolutely. We specialize in offline-first mobile architecture using Room and SQLite on-device databases with deterministic background synchronization when connectivity is restored.

Q4.How do you ensure mobile application security and user data privacy?

We enforce TLS 1.3 transport encryption, hardware-backed credential storage via Android Keystore and iOS Keychain, biometric authentication (FaceID / Fingerprint), and strict data minimization aligned with GDPR and Google Play policies.

Q5.What happens when Google or Apple releases new OS versions and SDK requirements?

We provide ongoing maintenance agreements to keep your target SDK levels, billing libraries, and privacy declarations updated ahead of store enforcement deadlines.
