[Blind-sysadmins] Trello and similar tools

Hi all, My team are investigating tools to help plan / track / visualize the work that we do. So far the favourite seems to be Trello but whilst this is usable in the strictest of senses, it's one of those situations where it's so fiddly to use that I can't really be as productive as I'd like. What do other people use for this sort of thing? Bonus points if it has an iOS app. The team are open to trying other solutions if they work better for me but if I can't find anything it's probably going to be Trello or Github. Cheers, Ben.
