I'm working with multiple customers and programmers, and I need some sort of online bugtracking and feature request software for apps we build. What do you all use? While I like basecamp, it's a bit overkill. I'm not looking for a full featured project management app. On the other hand, list apps tend to be too simple (i.e. can't assign a status like 'in progress', or assign ownership). Simple is better, people need to want to use it. Must be an online app, maybe with an iPhone app interface, and/or the ability to email a bug/feature to it. Anything like that? I've tried Redmine, RTM, and customers just quickly revert to sending us emails, which is a bloody mess.
