I use my own app[1] for when they're small, when it grows into a project, it often has to do with code, so then I have a repository with a todo txt file in it. I also use the concepts app [2] on my tablet to draw out mindmaps / charts /etc. I use taskpaper vim plugin so I can quickly collapse and expand items to not make the file too overwhelming. In the file I group topics / questions based on what makes sense for that project, and at the top of the file I often have a 'topic' where I can quickly dump thoughts, that then later have to be refactored into one of the real topics. I hope to one day find a way (and the time) to connect my ideas app with the repo txt file approach, so I can sync both. Conceptually I think the hard part of most problems is figuring out the real important questions you want to ask yourself. Once you think you know them, then the answer is either obvious, or requires you to do something (research, build prototype, etc).
