I’ve been using Jira Mate for a couple of weeks now, and it’s great. It’s one of those applications that just works. It sets out to do a useful but simple tasks, and does it brilliantly.
Installation and configuration is a snap. Download and install from the Apple App Store, enter your Jira instance details, and you’re done. Jira Mate fetches your saved filters, and lets you navigate to the issues. Right now Issues are read-only, but that should change in an upcoming release. And, smartly, while looking at an issue you’re only a button tap away from pulling the issue up in the iPhone’s Web Browser, where you can edit. You can get all the details on the Jira Mate Plugin Page, or read the author’s blog.
