I tend to use Workflowy.com for anything hierarchical/simple/listy and then Trello for anything bigger. For instance, recently did some CTO interview screenings via phone. It was really easy to set up a Trello board with a card per candidate, drop them in the list matching their current position in the pipeline, attach a resume, recruiter notes, due dates etc. The interview itself I threw as a bulleted list into Workflowy and just crossed things off as they were covered. Took notes in notepad and uploaded to the Trello board at the end. Invited stake holders to view the board and sent out a daily email with progress. Interviewed 8 candidates this way in a total of about 10 hours, including all the time spent prepping and scoring and communicating with the hiring team.
