This app started life as plastic credit cards (which you can still buy if you are old school) - each card is a summary of a training course.

Now you can get the whole lot for free, and you can refer to them on your android devices whenever you need to know anything about management.

Need a quick reminder of what to do when negotiating, how to give a presentation, how to plan a project, or how to be assertive? Just flip to the card and there are the top tips. If you need more you can click through to the website and read more in detail about each subject.
