Code Review Services & App Review Services | Let Brian Kayfitz Review Your Code

Need a Mobile App Code Review? Ship a better product with clear, maintainable code.

We’ve conducted hundreds of code reviews for developers, startups, and enterprise teams. Whether you’re looking for a one-time audit or ongoing oversight, we offer on-demand code review services tailored for mobile app development teams.

We specialize in what we affectionately call “Boring Code.” Why boring? Because boring code is predictable, readable, and easy to maintain—even months after it’s been written. You shouldn’t waste time deciphering clever or overly complex code. Great code should be clear, not clever.

It’s easy to write code that a computer understands. The real challenge—especially in teams—is writing code that humans can read, understand, and extend.

How to Submit Code for Review 

  1. First, fork your changes to a feature branch.

  2. When you’re ready to submit your code for review, simply create a pull request (or merge request) on your code hosting platform (e.g. GitHub, GitLab, Bitbucket).

  3. Select Brian as the reviewer or notify your team to assign him.

  4. Brian will review the changes and leave detailed, actionable comments to help improve code quality and maintainability.


It’s considered best practice to include a suite of automated tests with your pull request. This not only helps demonstrate that your changes meet the intended business requirements, but also ensures your code doesn’t break existing functionality. In fact, some code review workflows will automatically reject pull requests that don’t include appropriate unit tests.


Prevent App Store Rejections

One of the key purposes of a code review is to catch bugs or red flags that could block your app from being approved by the App Store or Google Play Console. This has become an increasing issue, especially when developers reuse third-party code or packages that may have been flagged for spammy or malicious behavior in other apps.

A thorough code review helps ensure that your app meets platform guidelines, avoids common pitfalls, and is more likely to be approved on the first submission.


As a senior mobile app developer, Brian recommends keeping your pull requests small and focused—ideally under 200 lines of code. Smaller pull requests make it easier for reviewers to provide clear, concise, and meaningful feedback, leading to faster approvals and fewer bugs.
