Native iOS, Android, and cross-platform mobile applications built by our Montreal team
Five Square Design specializes in mobile app development for businesses throughout Montreal and Quebec. As a Montreal-based development studio, we build mobile applications that combine excellent user experience with professional engineering standards.
Whether you need a native iOS app, Android app, or cross-platform solution using React Native or Flutter, our Montreal team handles everything from initial concept and design through development, testing, and App Store deployment.
Unlike agencies that outsource development, all our mobile app work is done in-house by our Montreal developers. You work directly with the people building your app, ensuring clear communication and accountability throughout the project.
Our mobile development services include native app development for iOS and Android, cross-platform solutions that work on both platforms from a single codebase, custom API development and backend integration, push notifications and real-time features, offline functionality, and ongoing maintenance and updates.
Working with a local Montreal team means direct communication in both English and French, no time zone issues, and developers who understand the Quebec market. All our services are fully bilingual.
We start by understanding your business goals, target users, and key features. We'll discuss platform choices (iOS, Android, or both), technical requirements, and create a detailed project roadmap.
Our designers create wireframes and high-fidelity mockups that follow platform-specific guidelines (iOS Human Interface Guidelines, Material Design). You'll see exactly how the app will look before development starts.
If your app needs a backend, we build secure, scalable APIs to handle data, authentication, and business logic. We use proven technologies and follow security best practices.
Our Montreal developers build your app using native technologies (Swift/Kotlin) or cross-platform frameworks (React Native/Flutter). You'll receive regular progress updates and working builds to test.
Comprehensive testing across devices, operating system versions, and real-world conditions. We test functionality, performance, usability, and edge cases before launch.
We handle the entire submission process for both App Store and Google Play, including screenshots, descriptions, and compliance requirements. We manage the review process and any required updates.
After launch, we monitor performance, fix any issues, and provide ongoing updates as iOS and Android evolve. We're here for the long term as your app grows.
Mobile app projects typically range from $30,000 to $150,000+ depending on complexity and features.
Most mobile apps take 4-8 months from kickoff to App Store launch.
• Platform choice (iOS only, Android only, or both)
• Native vs cross-platform development
• Design complexity and custom animations
• Backend and API requirements
• Third-party integrations (payments, maps, etc.)
• Offline functionality needs
• Push notifications and real-time features
It depends on your needs. Native apps (Swift for iOS, Kotlin for Android) offer the best performance and access to latest platform features, but require separate development for each platform. Cross-platform (React Native, Flutter) lets you build once and deploy to both platforms, reducing cost and time. We'll recommend the best approach based on your requirements, budget, and timeline.
Simple apps with basic features can take 3-4 months. Apps with custom design, backend integration, and complex features typically take 5-8 months. Enterprise apps with advanced functionality can take 8-12+ months. We'll provide a detailed timeline during the planning phase.
Yes! We manage the entire submission process for both Apple App Store and Google Play Store, including creating store listings, screenshots, descriptions, and handling the review process. We'll guide you through setting up developer accounts if needed.
Absolutely. As a Montreal agency, we specialize in bilingual apps for the Quebec market. We can build full French/English interfaces and handle all localization requirements.
We provide post-launch support including monitoring, bug fixes, and updates as needed. We can also handle ongoing maintenance, feature additions, and updates for new iOS/Android versions. No long-term contract required—work with us as needed.
Let's discuss your Montreal mobile app project and create something exceptional together.
