A simple-to-use tool for reporting software issues and getting them into our Trello workflow.As a small team, wearing many hats, has really streamlined how we develop software. We use it to develop our own Saas platform and also when developing our own website. We used to take screenshots with a regular snipping tool but then had to go into Trello, create a new card and then upload the screenshot. It was tedious so not all issues were reported. With that entire process is simplified to one single move! An additional plus is that it's 100% Chrome based so those of us who work with Chromebooks can partake in the bug reporting process.

The ability to create cards on the fly without even having trello open is absolutely remarkable. This product has changed the way we do release management and bug testing. Not to mention I can organize to multiple boards at a single instance.

This is the kind of software that saves you time allowing you to focus on what really matter.As a developer, I love that all issues reported into Jira actually come with the source URL and information about the user environment (Browser, OS, screen size, ...)

I am the support manager for one of the products that my company develops, and so has made communicating things with my development team extremely simple. - The GitHub integration means I can post new issues quickly and efficiently, vs. having to take a screenshot, mark up the screenshot, and then upload it to GitHub. - The fact that most of our GitHub items for our repository are right there when creating an issue with means I can create an (almost) complete issue with all the tags, assignees, and information already in the issue without having to jump to GitHub to add these things. - All of the data it captures about my environment is helpful to my development team, so they get a clear idea of the situation. In fact, my team has had such good success with that another one of our products in the company now uses it as well.
