RIO XL

My go-to tool for laying down creative ideas. Like a musical scratch pad and inspiration engine. My only gripes are UI design related. Example is the small text and crammed feeling of it’s controls. The text colours and panel colours are often nearly the same hue and luminance, making for poor readability due to lack of contrast.

Out of all the options there are for dictionaries, this is my personal favourite. It's simple and clean with no distractions.
