Our Process

How a project runs

A predictable sequence, with a decision point at the end of each stage.

Requirements, constraints, existing systems and the people who depend on them.
Discovery
Planning
Scope, milestones, effort estimates and a written statement of work.
Data model, integrations, hosting and rendering strategy agreed before build.
Architecture
Development
Iterative delivery on a staging environment you can review at any point.
Functional, responsive, accessibility and performance checks against the scope.
Testing
Deployment
Release, DNS and SSL, monitoring and a rollback plan in place.
A maintenance plan with defined response times and a named point of contact.

FAQ

Questions, answered

Straight answers to what clients usually ask before we start working together.

What does mobile app maintenance include?

Depending on the agreed scope, it can include bug fixes, compatibility updates, dependency updates, performance checks and API-related changes.

Can you maintain an app developed by another team?

Yes. We can first review the existing codebase, technology stack and deployment setup to understand the app and identify the support work required.
