Linear released Mobile Diffs on November 5 in the latest iOS and Android apps. The Reviews tab lets a reviewer open a pull request, inspect changed code, and comment on a specific line from a phone. The review stays alongside the Linear issue that explains why the change was requested.
A review can move between devices
Guided Reviews divide the change into sections. A reviewer can open a preview link directly from the diff, which is useful when the change affects a mobile layout. Linear says files marked as viewed on a phone stay marked on desktop, so someone can check a small fix on the go and continue through the rest later.
The mobile app also supports replying to review threads and merging approved changes. Linear’s documentation says a reviewer needs the appropriate permission to merge. For a GitHub repository, the workspace’s integration needs code access to display file diffs, and the reviewer needs a personal GitHub connection.
A first review can start with one small pull request. Check that the diff opens, that a comment reaches the right line, and that the viewed files carry over when the same review is opened on desktop.
