App Development Ottawa: Our Services

We handle iOS, Android, cross-platform, and web development from initial concept to post-launch support. Whether you need a native app, a progressive web app, or connected IoT software, our team builds solutions that solve real problems.

 

Android App Development

We build native Android applications using Kotlin and Java for phones, tablets, and wearables. Our developers follow Material Design guidelines and optimize for performance across different devices and Android versions.

iOS App Development

We develop native iOS apps using Swift and SwiftUI for iPhone, iPad, and Apple Watch. Our team handles App Store submission, TestFlight distribution, and compliance with Apple's latest requirements.

Cross-Platform Development

We use React Native, Flutter, and Kotlin Multiplatform to build apps that run on both iOS and Android from a single codebase. This approach reduces development time and maintenance costs while maintaining native-like performance.

Web Application Development

We build progressive web apps (PWAs) and responsive web applications that work across browsers and devices. This extends your mobile product to desktop users and reduces App Store dependency.

IoT & Connected Devices

We build mobile apps that connect with physical products through Bluetooth, Wi-Fi, RFID, beacons, and sensor networks. Our team handles device pairing, real-time data synchronization, firmware updates, and offline operations for connected home devices, wearables, medical equipment, and industrial hardware. See our IoT development services for case studies and technical details.

AR/VR Development

We design augmented reality and virtual reality experiences for iOS and Android using ARKit, ARCore, and Unity. Our work includes product visualization, training simulators, and immersive brand experiences.
