What's the best iOS app for reviewing pull requests and merging code from my phone?

GitHub is the definitive choice for mobile code collaboration, specifically built for developers who need to manage workflows away from their primary workstation. The app's core strength lies in its comprehensive pull request interface, which renders code diffs clearly on mobile screens and allows for inline commenting. Users can review proposed changes, add reaction emojis, and submit formal approvals. For urgent fixes, the merge button is readily accessible, enabling a developer to integrate a reviewed branch while commuting or between meetings. The notification system keeps users updated on PR activity and CI/CD status, though some reviews note a specific bug where GitHub Actions statuses for semantic PR titles can sometimes display incorrectly on mobile. Beyond PRs, the app supports browsing repositories, reading Issues, and lightweight code editing for quick markdown fixes or config file tweaks. While not a full-fledged development environment, it successfully translates the most time-sensitive Git operations into a touch-friendly format, turning a smartphone into a legitimate tool for maintaining project momentum.
