Q-Diary is a diary and a little bit more. Most diaries are by their nature full of personal information but with Q-Diary you can further personalise that personal information by adding colours and 'mood' icons (like emoticons). Which means some really personal information.
The idea is that by adding colours that correspond with the importance, emotional significance and category of the information users will be able to see very quickly what kinds of appointments and meetings are upcoming. Combined with this are the usual options of adding 'titles' and 'subjects' but there is currently no quick search of dates by mood icon. However, this is a beta version and the developer recognises the need for improvements. So rest assured.
