Android & iOS App Development Built for Performance, Scale & Security.

Three mobile development tracks: Native iOS development with Swift and SwiftUI; native Android development with Kotlin and Jetpack Compose; and cross-platform development with React Native and Flutter. All tracks include enterprise system integration, UI/UX design, AI feature integration, backend and API development, QA and testing, App Store and Google Play submission, and ongoing managed support. Delivered for Fortune 500 enterprises across manufacturing, healthcare, logistics, financial services, and retail.

Native iOS (Swift/SwiftUI) and Android (Kotlin) deliver maximum performance, deepest device hardware integration, and the most platform-consistent user experience – recommended for apps requiring intensive real-time processing, complex animations, deep hardware integration (CoreMotion, HealthKit, ARKit), or that must closely follow platform-specific design standards. Cross-platform (React Native or Flutter) delivers near-native performance with a 30–50% reduction in development cost and time – recommended for most enterprise business applications where platform-specific native capability is not the primary requirement. Kernshell recommends the right approach for your use case during discovery, not based on our development team preference.

An MVP mobile application with core features typically takes 12–16 weeks from discovery to App Store submission. A full-featured enterprise mobile application – complex workflows, multiple enterprise integrations, AI features, and offline capability – is typically 20–32 weeks depending on scope and integration complexity. Timeline is defined with clear milestones following the product discovery and technical architecture phase, not estimated from a feature list before requirements are understood.

Via production-grade REST and GraphQL APIs – SAP, Salesforce, Microsoft Dynamics, Oracle, and custom operational systems connected with bidirectional data flow, real-time synchronisation, and offline capability with conflict resolution for intermittent connectivity environments. Every integration is mapped during discovery, built as a first-class development deliverable, and validated end-to-end before production launch. No integration is assumed to work – every connection is tested under representative load before App Store submission.

Yes. Offline capability is engineered as an architectural requirement, not added as a feature after development begins. We implement local data storage using CoreData (iOS) and Room (Android), offline-first synchronisation architecture with conflict resolution, background sync when connectivity is restored, and graceful degradation of features that require live connectivity. Field operations, warehouse, and clinical mobile apps are designed for the connectivity conditions of the operational environment, not the Wi-Fi-connected office where they were developed.

Security and compliance are designed into mobile architecture from the first technical decision – not applied as a security review finding after development. We implement biometric authentication (Face ID, Touch ID, Android Biometric API), encrypted local data storage, certificate pinning, OWASP Mobile Security Top 10 mitigation, secure API communication (OAuth 2.0, SAML, SSO), and role-based access controls. For HIPAA-regulated healthcare mobile apps, we implement BAA-aligned data handling, minimum necessary access controls, and audit logging meeting clinical documentation requirements.

App Store (Apple) and Google Play submission is managed end-to-end – metadata preparation, screenshot and preview production, privacy policy compliance review, App Store Review Guidelines compliance, and submission management. Post-launch, we provide ongoing managed support covering iOS and Android OS compatibility updates (Apple and Google release major updates annually requiring testing and adaptation), performance monitoring, crash analytics, security patching, feature releases, and App Store compliance management as platform requirements evolve.
