    FREQUENTLY ASKED QUESTIONS

    Frequently Asked Questions About Mobile App Development

    Answers to common questions about iOS and Android development, cross-platform apps, integrations, modernization and working with Qualhon.

    Qualhon designs, develops and modernizes mobile applications for iOS and Android. Our services include native and crossplatform app development, enterprise mobility, connected-device applications, mobile backend and API integration, UI/UX engineering, and improvements to existing apps.

    Yes. We work on applications for iOS and Android, including native development and cross-platform approaches. We recommend the technical route based on the intended users, features, device capabilities, existing systems and maintenance needs.

    Both approaches can be suitable. Native development may be preferable for particular platform-specific requirements, while cross-platform development can share parts of an application across iOS and Android. We review your features, integrations, performance needs and long-term roadmap before recommending an approach.

    Yes. We develop and integrate mobile apps with existing backend systems, APIs, databases, authentication services and relevant third-party platforms. The integration plan depends on the interfaces and data flows already available.

    Yes. Depending on the hardware and supported communication interfaces, we can develop mobile applications that exchange data with connected devices, such as solutions involving Bluetooth / BLE, device synchronization and related backend workflows.

    Yes. We assess existing apps and help with interface improvements, codebase updates, architecture changes, integrations, supported operating-system requirements and ongoing feature development. The recommended scope depends on the condition and structure of the current application.

    The timeline depends on the number of platforms, features, design complexity, backend requirements, integrations, testing and release considerations. After reviewing the requirements, we can propose an implementation plan with phases and estimated timelines.

    Mobile app development costs depend on the app’s scope, native or cross-platform approach, user experience, backend integrations, hardware requirements and delivery expectations. We first discuss your requirements and then recommend a suitable engagement structure and estimate.
