Common Questions

Frequently Asked

Our maintenance covers OS compatibility updates, bug fixes, performance monitoring & optimisation, security patches, dependency updates, and minor feature enhancements. We tailor the scope to your app's needs.

Critical issues (app down or data loss) get a response within 4 hours. High priority issues within 24 hours, medium within 72 hours, and low priority items are scheduled into the next maintenance sprint.

We offer flexible monthly retainer plans based on app complexity and required support level. Plans include a set number of development hours, monitoring setup, and SLA guarantees. No lock-in contracts.

We start with a comprehensive app health assessment, then onboard your codebase into our systems. We set up monitoring, configure CI/CD access, and establish communication channels — typically completed within one week.
