Frequently Asked Questions: Mobile Apps

We primarily develop cross-platform apps using React Native and Expo, which allows us to build from a single codebase for both iOS and Android. This approach delivers native look & feel and performance while reducing development time and costs. For apps with very specific performance requirements or platform-specific features, we can also develop fully native apps in Swift/Kotlin.

We start with a Sprint of about four weeks. The goal is a runnable beta of your app's most important workflow in production-like quality, which you test on real devices via TestFlight and Google Play internal testing. Further features such as real-time sync, offline mode or AI integration we then build in stages in the Build & Support format, with a demo after each stage, up to submission to the App Store and Play Store. How many stages your app needs is defined after scoping. The Sprint is offered at a fixed price after scoping, with a quote within 48 hours.

We manage the complete submission process for both Apple App Store and Google Play Store. This includes setting up developer accounts, preparing app metadata and screenshots, ensuring compliance with store guidelines, handling the review process, and addressing any rejection issues. We stay up to date with current store requirements so that submissions pass on the first attempt whenever possible.

In the Build & Support format we handle bug fixes, OS compatibility updates and feature enhancements; bugs you report within 30 days of final delivery are fixed free of charge in any case. For minor updates and content changes, we use Expo's EAS Update (over-the-air), which delivers changes instantly without App Store review. Major updates with native code changes go through the standard store review process. We also provide monitoring, crash reporting, and analytics to ensure your app runs smoothly.

Security is built into every layer of our mobile apps. We implement secure authentication (OAuth, biometrics), encrypt sensitive data both in transit (TLS/SSL) and at rest, follow OWASP Mobile Security guidelines, conduct regular security audits, and ensure compliance with data protection regulations like GDPR. We also implement secure API communication, certificate pinning, and jailbreak/root detection when needed.

Absolutely! We specialize in integrating mobile apps with existing backend systems, APIs, and databases. Whether you have a REST API, GraphQL endpoint, or custom backend, we can connect your mobile app seamlessly. We also handle authentication integration, data synchronization, and can work with your existing cloud infrastructure (AWS, Azure, GCP). If needed, we can also extend or optimize your backend for mobile-specific requirements.
