Our iOS app development team builds native applications using Swift and SwiftUI. Native iOS development gives you the best performance, tightest integration with Apple's ecosystem, and access to the latest platform features the day they launch. We've built iOS apps for clients ranging from early-stage startups shipping their first MVP to established Miami businesses expanding into mobile. For companies that need the highest-quality iOS app development experience, a native Swift app is the fastest path to a smooth, reliable product.
Android holds roughly half of the U.S. smartphone market and an even larger share globally. Our Android app development team uses Kotlin and Jetpack Compose to build apps that perform well across the full range of Android devices. We handle the fragmentation so you don't have to -- testing across screen sizes, OS versions, and hardware configurations to make sure your app works everywhere your users are. For Miami businesses targeting the broadest possible audience, Android app development is essential.
When you need to reach both iOS and Android users without doubling your budget, cross-platform development is the practical choice. We build cross-platform apps using Flutter and React Native, two frameworks that let us ship a single codebase to both platforms with near-native performance. Cross-platform development typically cuts 30-40% off the timeline compared to building two separate native apps. For many Miami businesses -- especially startups watching their runway -- that tradeoff makes sense.
Mobile apps don't exist in a vacuum. Most of our Miami clients also need web applications, admin dashboards, APIs, or customer-facing websites that tie into their mobile products. As a web development agency Miami companies rely on, we build custom web applications using React on the frontend and Node.js or Laravel on the backend. We deploy to AWS, Firebase, and Azure depending on your scale and compliance requirements.
Miami's economy is distinct, and we've built software for the industries that drive it.
Miami has become a serious FinTech hub. We build secure, compliant financial applications -- payment platforms, banking interfaces, and investment tools -- that handle sensitive data responsibly and meet regulatory requirements.
From telehealth platforms to patient intake apps, we build healthcare software for Miami that prioritizes usability and data security. If your project involves protected health information, we build with HIPAA considerations from day one.
Miami's real estate market moves fast. We've built property search apps, agent tools, and transaction platforms that help real estate professionals close deals faster and give buyers a better experience.
Whether you're selling online, managing inventory across locations, or building a marketplace, we develop e-commerce solutions that scale with your business. Mobile commerce is where Miami shoppers are headed, and we build for that.
Miami's hospitality industry needs technology that keeps up with guest expectations. We build booking systems, loyalty apps, and operational tools for hotels, restaurants, and entertainment venues across South Florida.
We follow an agile development process built around two-week sprints, regular check-ins, and working software you can see and test throughout the build.
Step 01
We start by understanding your business, your users, and what success looks like. This phase produces a clear project scope, technical architecture, and timeline.
Step 02
Our designers create wireframes and high-fidelity mockups. You review and approve designs before a single line of code is written.
Step 03
We build in agile sprints, delivering working features every two weeks. You get access to staging builds so you can test progress in real time.
Step 04
Every feature goes through manual and automated testing across devices and platforms. We catch bugs before your users do.
Step 05
We handle App Store and Google Play submissions, server deployment, and launch-day monitoring. Most projects go from kickoff to launch in six to eight weeks.
Step 06
Software doesn't end at launch. We provide ongoing post-launch support, maintenance, bug fixes, and feature updates to keep your app running smoothly and your users happy.
We work with clients across the greater Miami metropolitan area and South Florida, including:
Whether you're a startup in Brickell or an enterprise in Coral Gables, our Miami team is local and available for in-person collaboration.
App development costs in Miami vary based on complexity, platform, and feature set. A straightforward MVP typically starts around $25,000-$50,000, while more complex custom mobile app projects with backend infrastructure, integrations, and multi-platform support can range from $75,000 to $200,000+. The best way to get an accurate estimate is to book a free discovery call where we scope your specific requirements. We offer transparent pricing and will give you a detailed breakdown before any work begins.
Most of our mobile app development projects launch in six to eight weeks from kickoff. Simpler MVPs can ship faster, while complex enterprise applications with extensive integrations may take 12-16 weeks. Our agile sprint process means you'll see working software within the first two weeks, not just wireframes.
Yes. We offer iOS app development using Swift, Android app development using Kotlin, and cross-platform apps using Flutter and React Native. Many clients choose cross-platform development to reach both audiences simultaneously while keeping costs and timelines manageable.
For mobile app development, we work with Swift (iOS), Kotlin (Android), Flutter, and React Native (cross-platform). On the web side, our stack includes React for frontend development, Node.js and Laravel for backend services, and AWS, Firebase, and Azure for cloud infrastructure. We choose the right tools for each project rather than forcing every client into the same stack.
Absolutely. We provide ongoing post-launch support including bug fixes, performance monitoring, OS update compatibility, feature additions, and scaling assistance. Software needs care after launch, and we stay with our clients long after the initial build is complete.
Working with app developers in Miami means same-timezone communication, the option for in-person meetings, and a team that understands the South Florida business landscape. Our U.S.-based senior developers are not junior offshore contractors cycling through your project. You get experienced engineers who stay on your project from start to finish. We've been delivering mobile app development Miami businesses depend on for over six years, and that continuity matters when you need a partner, not just a vendor. We also offer NDA protection from the first conversation.
