Super east to collaborate in team meetings. We've used post-its, Asana, and others to conduct retrospectives and brainstorms. TeamRetro is especially helpful with a remote team who can't all be in the same room.

TeamRetro allows for our team to gather all of our opinions on business processes in between our 'sprints'. This allows for everyone to bring feedback to what our focuses could/should be. I really like how you can customize what the fields are for the team to go off of,

My favorite thing about TeamRetro is that you can do it anonymously. People can share how they truly feel about how things went without having to be public.
