Your customers are on their phones. Your app should be too.

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.

React Native MVP Build

Common questions.

React Native or native development — which do you recommend?

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.

How much does an app cost?

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.

Do you own the source code?

Yes — you own all source code, assets and IP. We provide a full code handover at project completion.

Can you take over an existing app?

Yes — we conduct a code review first to assess architecture and quality, then provide a plan for either continuation or a rebuild recommendation.
