Mobile app development

Mobile app development in Montréal, from app to system.

Underlabs designs and builds iOS and Android applications with the backend, administration and integrations they need to work in production.

The app is only the front door. We build the system behind it. Our Montréal team connects mobile experiences to the services, data and operational tools that make them useful.

What we build

iOS and Android applications for customers, staff and field teams, with native or cross-platform delivery chosen for the product's needs. The work can include cloud services, APIs, permissions, administration and integrations, not just screens.

  • iOS and Android applications
  • Backend services and API integration
  • Administration and operational workflows
  • Testing, store preparation and release support

How we approach delivery

We start with the users, critical workflows and existing systems. Then we define the first useful release, design the connected architecture, build in reviewable increments and test the paths that matter before launch.

What shapes scope and cost

Roles, offline needs, device features, integrations, data and backend complexity all affect the work. The app cost guide explains the main scope decisions; a project conversation can establish an estimate for your case.

Start with the real problem

Share the users, essential workflows, existing systems and decisions still open. We can help determine whether mobile is the right front door and what belongs behind it.

FAQ

Common questions

Do you build native or cross-platform apps?

Both. The choice depends on device capabilities, performance needs, team constraints and the expected life of the product.

Can Underlabs build the backend too?

Yes. Mobile products often need APIs, authentication, administration, data workflows and infrastructure designed as one system.

Can you modernize an existing app?

Yes. We assess the codebase, product experience, integrations and release risks before recommending a focused path.
