Code Review: Ensuring Quality, Security, and Best Practices in Apps

Code Review

Code review is when developers check each other’s code to catch bugs, improve quality, and ensure everything works smoothly before going live.

Why It Matters 

  • Ensures your app is stable and bug-free before launch

  • Saves money by catching issues early instead of post-release

  • Improves performance and security through peer input

  • Encourages consistent coding practices

  • Builds stronger team collaboration and accelerates onboarding

Use This Term When...

  • Planning a quality assurance or testing process

  • Discussing workflows or version control

  • Reviewing bugs and how to prevent them

  • Setting team coding standards

  • Focusing on maintainable codebases

Real-World Example 

In the project, we implemented regular code reviews to maintain high-quality standards, identify issues early, and ensure consistency across the team. This contributed to a stable, secure, and maintainable product.

Founder Insight

Skipping code reviews may save time short-term but leads to long-term pain. Bugs, crashes, and team misalignment are far costlier to fix later. Make code review a standard part of your development culture—even for MVPs.

Key Metrics / Concepts

  • Defect Density: Bugs found per lines of code

  • Review Coverage: Percentage of code that was peer-reviewed

  • Turnaround Time: How quickly reviews are completed

Tools & Technologies

  • GitHub / GitLab: Code hosting with built-in review features

  • Bitbucket: Pull request and collaboration features

  • SonarQube: Static code analysis and automated review support

What’s Next / Future Trends


AI is beginning to play a role in automated code reviews—flagging security flaws, recommending improvements, and learning from review history. Expect faster reviews, more standardisation, and fewer bugs through smart tooling.
