Very useful
This app is not perfect, but I find that I can get a lot done with it in specific areas that are really terrible in the main Jira mobile app. Because of the way it’s organized around a page of shortcuts, you can get where you want really quickly if you set it up correctly and the support it has for dashboards is very good. If you have a few things that you do all the time, like file an issue or check the status of a release, or view the results of a filter - you can set the app up to do those things really rapidly, which doesn’t sound important until you realize how much of your life you’ve probably wasted clicking through a million parts of Jira, one step at a time, multiple times a day.
