A well-structured and practical look at mobile app maintenance. I particularly liked the distinction between corrective, adaptive, preventive, and perfective maintenance—it makes it clear that long-term app reliability involves much more than simply fixing bugs.
The discussion around observability, dependency management, CI/CD, security updates, and backend/API dependencies is especially relevant. These areas are often overlooked until they become production issues.
The patch-versus-refactor-versus-rebuild section is also valuable, as it encourages teams to address underlying architectural problems instead of continuously applying short-term fixes. Overall, a useful reference for teams planning a sustainable mobile app maintenance strategy.
