App Description

Wouldn't it be great to know more about people’s (including yourself) personalities, preferences, behaviors, motivations, and backgrounds?

Personal and Interpersonal success depend greatly on understanding the self and others, and this application is a useful tool in that challenge.

Popular psychology has taken great steps recently, and there is an increasing amount of books that cover its entertaining and informing topics. Psychology-I is a great entry point to the great world of psychology, personalities, and behaviors. It combines interest with practical benefit to produce a highly useful and informing set of ideas.

Psychology-I contains well written, concise, and rich-enough summaries of highly important and influential books that cover personalities, judgment, behavior, habits, intelligence, memory, irrationality, motivation, and more…


Start with taking the temperament sorter questionnaire, learn more about your personality profile (and those of others), and then go on to read about making better decisions, understanding behavior, the different intelligences, motivation, and irrationality.

The aim has been to make the summaries as informing as possible, while avoiding excess technical description, and including as many examples and case studies as possible.


Psychology-I presents an arsenal of ideas that spans psychology, sociology, behavioral economics, brain science and neurology, and strategy and decision making.


Note: Please note that the book summaries in this app are offered as an in-app purchase and are NOT for free. This app doesn't bombard you with unwanted advertising, so please accept our model of revenue since creating maintaining this content takes a lot of time and effort.
