We build mobile applications for iOS and Android across all levels of complexity – from simple business tools and MVPs to full e-commerce platforms and content services. Whether you need a native iOS app in Swift, an Android application in Kotlin, or a cross-platform solution, we handle design, development, testing, and App Store/Google Play publishing under one roof. Our clients range from startups to established enterprises that need a product built to perform commercially, not just technically. Every project runs on milestone-based timelines with agreed deadlines, so you always know exactly where things stand and when your app will launch.

Mobile App Development
ITllect is a Florida-based app development company building custom mobile apps for businesses and startups of any size. Whether you need a native iOS app in Swift, an Android application, or a cross-platform solution that runs on both - we take your idea from the initial brief all the way to live on the App Store and Google Play.
iOS App Development
We build native iOS applications for iPhone and iPad using Swift - Apple's modern, high-performance language. Native Swift development gives your app access to the full iOS feature set, smoother performance, and a user experience that feels exactly how Apple users expect it to.
Android App Development
Our Android development team builds applications in Kotlin and Java for smartphones and tablets across all current Android versions. From lean business tools to data-heavy platforms, we build Android apps that perform reliably across the full range of devices and screen sizes.
Cross-Platform Apps
Need your app on both iOS and Android without building two separate products? Cross platform app development lets you reach both audiences from a single codebase - reducing build time and budget without meaningfully compromising on performance or native feel.
Why choose ITllect
Technologies We Build With
Our mobile and web development team works across a versatile tech stack-including Swift, Kotlin, Java, PHP, and Symfony. We focus on choosing the right tool for your specific project rather than defaulting to what’s familiar. By staying ahead of platform updates, SDK changes, and evolving App Store and Google Play requirements, we ensure the products we deliver are built to robust standards. Our apps aren’t just designed to launch successfully; they are engineered to endure and scale as the platforms change around them.
Stages of mobile APPs development
Discovery & Scoping - We dig into your idea, define the full feature set, and give you an honest scope and timeline before any work starts. No surprises mid-build.
Prototype & UI/UX Design - Before a line of code is written, you see a working prototype and full screen designs. This is where issues get caught cheaply, not expensively.
Development & Testing - Built in milestones, tested continuously, and reviewed against the original brief at each stage before moving forward.
App Store & Google Play Publishing - We handle the full submission process for both platforms, including compliance with store guidelines and review requirements.
Ongoing Support - Post-launch support to push updates, fix bugs, and add new features as your product evolves and your users grow.
Growth & Marketing - Post-launch campaigns to build awareness, acquire customers, and maximize visibility as your product evolves and your audience grows.
Frequently asked questions
Mobile application development cost depends on complexity, platform, and required features. A straightforward business app typically starts from $10,000-$15,000. More complex apps with custom backend infrastructure, third-party integrations, or advanced functionality run $30,000-$75,000 and above. Contact us for a scoped estimate based on your specific requirements.
A simple app takes 2-3 months from brief to launch. Mid-complexity apps typically run 4-6 months. Products with custom infrastructure or large feature sets can take 6-12 months. We provide a fixed timeline at kickoff and hold to it.
Business tools, e-commerce apps, content platforms, booking systems, promo apps, and custom startup products. If you have a specific use case in mind, get in touch and we'll tell you honestly what it takes to build it.
We build for iOS, Android, and both simultaneously. For most projects we recommend starting with one platform based on your target audience, then expanding. If budget and timeline allow, we can build native apps for both in parallel or use a cross-platform approach to cover both from a single codebase.
Yes. All source code, assets, and intellectual property produced during the project are fully yours on final payment. We don't retain licensing rights or lock you into ongoing contracts to access your own product.
A clear idea of what the app needs to do and who it's for. You don't need a technical brief or wireframes - that's our job. An initial call is enough to establish scope, platform, and rough timeline. From there we handle everything through to launch.
