Mobile App Design and Development in Toronto
I design and build iOS and Android apps that people find easy to use, from the first idea and user research to launch in the App Store and Google Play.
I’ve designed payment features for TD’s iOS and Android banking apps and a digital health platform for Ontario Health. Whether you’re a startup with a new idea or a team improving an existing app, I can take it from concept to launch.
Mobile app design and development services
App strategy and research
Who the app is for, what it needs to do first, and what will bring people back. Interviews, competitor reviews and analytics turn assumptions into a clear plan.
UX design and user flows
Onboarding, sign-in, payments, forms and settings mapped out as flows, so the app feels simple even when what sits behind it is complex.
iOS and Android UI design
Screens that feel at home on each platform, following Apple’s Human Interface Guidelines and Google’s Material Design while keeping your brand consistent.
Prototyping and usability testing
Clickable prototypes tested with real users on real phones, before development starts.
App development
I build the app for iOS and Android and take it through App Store and Google Play review.
Launch and improvement
Analytics, user feedback and regular updates after launch to improve retention and ratings.
Apps for finance, health and other regulated industries
Secure sign-in, payments, consent screens and personal data all need to feel clear and trustworthy, or people abandon the app. I’ve designed these flows for TD and Ontario Health, working with security, legal and accessibility requirements from the start.

How an app project works
- Discovery. We define who the app is for, the problem it solves and what success looks like.
- Research. I talk to users and review competitors and data to shape the first version.
- Flows and wireframes. The key journeys are mapped out before any visual design.
- Prototype and test. A clickable prototype is tested with real users, then refined.
- UI design. Final screens and components for iOS and Android.
- Build and release. The app is developed, tested on devices and submitted to the stores.
- Improve. After launch, data and feedback guide the next updates.
What you get
- A clear plan for the first release
- User flows and wireframes for the key journeys
- A clickable prototype tested with users
- High-fidelity UI for iOS and Android

Mobile app design FAQ
How much does it cost to design and build an app?
It depends on the number of screens, features and integrations. After a short discovery call you get a fixed quote and timeline for the first release, before any work starts.
Should I launch on iOS or Android first?
It depends on your audience. In Canada both platforms matter, and building for both at once is often the best value. We decide this together during discovery.
Can you redesign my existing app?
Yes. I start with a review of your current app, its ratings and its analytics, then redesign the parts that cause the most problems first.
Can you work with my developers?
Yes. I can design and build the whole app, or design it and work alongside your in-house or agency developers.
Do you only work with Toronto companies?
No. I’m based in North York and happy to meet clients across the GTA in person, and I work remotely with teams across Canada and the US.
