Frequently Asked Questions About App Development
Clear, honest answers to the questions we get asked most often by clients considering app development.
Development timelines depend on complexity. Simple apps with core features typically take 2–3 months. Medium-complexity apps range from 3–5 months, while feature-rich enterprise applications may take 6–9 months. We provide detailed, milestone-based project timelines after the discovery phase so you always know exactly what to expect.
We develop native apps for iOS (iPhone and iPad using Swift and SwiftUI) and Android (using Kotlin and Jetpack Compose). We also build cross-platform apps with React Native and Flutter that run on both platforms from a single codebase. We recommend the best approach for your specific budget, performance needs, and audience.
Yes — all projects include a 30-day post-launch warranty at no extra cost. Beyond that, we offer flexible maintenance packages covering bug fixes, OS compatibility updates, security patches, performance optimisation, and new feature development. Our 24/7 support team monitors your app around the clock and responds to critical issues rapidly.
Security is built into every layer of our development process. We implement AES-256 data encryption, TLS/SSL for all data in transit, secure OAuth 2.0 authentication, biometric access controls, and regular penetration testing. We comply fully with GDPR, HIPAA, CCPA, and PCI-DSS requirements depending on your industry and jurisdiction.
We offer three engagement models: Fixed-Price for well-scoped projects with clearly defined requirements; Time-and-Materials for evolving projects where scope may grow; and Dedicated Team for long-term product development. We'll recommend the most cost-effective model during your free initial consultation after understanding your project needs.
Absolutely. Our team handles full App Store and Google Play submission including keyword-optimised metadata, screenshot design, preview videos, and category selection to maximise organic discoverability. We also guide you through launch strategies, user acquisition, ratings management, and can connect you with trusted growth marketing specialists.
