iOS, Android, React Native and hybrid apps. From lean MVPs to enterprise-scale platforms — built with clean code, tested thoroughly and launched on schedule.
Mobile apps have fundamentally changed how businesses interact with customers. A well-built app isn't just a convenience — it's a retention engine, a revenue channel and a competitive moat. Customers who use your app have a 3× higher lifetime value than those who don't.
The challenge is that app development has traditionally been expensive, slow and risky. Long build times, scope creep, communication gaps between business and developers, and apps that miss the market.
HOI's mobile development approach starts with an MVP mindset — build the core functionality fast, launch, get real user feedback, then iterate. We've shipped 30+ apps across iOS, Android and React Native on time and on budget. Our track record is 100% on-time delivery.
Native iOS (Swift) and Android (Kotlin) development for apps that require maximum performance and platform-specific features.
Cross-platform development with React Native — one codebase for iOS and Android. Faster delivery, lower cost, excellent performance.
App interfaces designed for the way people actually use mobile — thumb-friendly, fast and intuitive.
Full backend development and third-party API integrations — payment, authentication, notifications and data.
Rigorous testing on real devices across iOS and Android — not just simulators. Zero compromises on quality.
App Store and Play Store submission, launch support and ongoing maintenance and feature development.
We understand your app concept, users and business goals. You receive a detailed scope document with timeline and fixed cost.
UI/UX design and interactive Figma prototype in 1–2 weeks. You experience the app before development begins.
Agile development in 2-week sprints with demo at the end of each. Continuous QA throughout the build.
App Store and Play Store submission, launch support and post-launch analytics to guide the next iteration.
React Native for most apps — it delivers near-native performance with a single codebase, reducing build time and cost by ~40%. We recommend native iOS/Android only when you need maximum performance or deep platform-specific features.
MVP apps typically range from $15,000–$35,000. Full-featured consumer or enterprise apps range from $40,000–$150,000+. We provide a fixed-cost quote after the discovery phase.
Yes — you own all source code, assets and IP. We provide a full code handover at project completion.
Yes — we conduct a code review first to assess architecture and quality, then provide a plan for either continuation or a rebuild recommendation.
