Common questions

What is mobile app development? →

Mobile development at Essen Software is building Native (iOS/Android) or Cross-Platform (Flutter, React Native) apps—from discovery and design to App Store and Play Store launch—with a focus on performance and user experience.

Native vs cross-platform: which does Essen recommend? +

Native gives maximum performance and platform fit; cross-platform (Flutter/React Native) is faster and cheaper for multi-platform. We recommend based on your timeline, budget, and performance needs.

How long does it take to launch a mobile app? +

MVPs often ship in 8–12 weeks; full enterprise apps take longer. We work in agile sprints with device testing and handle App Store and Play Store submission.

How much does a mobile app cost to build? +

Most apps run $8k–$30k fixed scope: single-platform MVPs at the low end; cross-platform apps with backends, payments, and real-time features toward the top. Our senior team has production apps live on both stores across marketplaces, services, and fintech.

Can you build AI-powered mobile apps? +

Yes — AI chat, recommendations, image features, and voice, both API-based and on-device. We ship Flutter and React Native apps with AI in the core flows, backed by the same team that runs our AI development practice.
