What’s your personality? How do you and your loved ones, friends, and co-workers compare? Imagine having quick access to the right keywords to get your point across!

Whether you’re in a boring meeting, on the phone with a challenging client, or dealing with a flustered family member — this application is for you. The essential themes of each personality Type are just a tap away. You can also explore each personality in depth: learn a person’s core needs and values, cognitive processes, interaction style, team behavior, pitfalls, growth points, and much more.

You will quickly learn about Type Theory and how to positively influence others using the “Compare” feature. This feature relies on sophisticated algorithms to show you the likely commonalities, differences, and synergies between two people. The algorithms compare communication, problem solving, learning and adaptation, love relationships, growth and change, and more.

Personality is far more than just superficial traits. Personality reveals motivation and cognition — why (and how) people act. In short, this application helps you discover what makes people “tick”. When you know why someone needs something, or how they prefer to go about doing a task or interaction, then you have leverage to improve the situation.

For almost six decades, thousands of successful professionals — counselors, teachers, managers, coaches, salespeople, and others — have used the insights of Type Theory. Type Theory is supported by decades of published statistical analysis of over six million people.

The famous and highly respected Dr. Carl Jung first described eight cognitive processes people use. The eight processes combine to match the sixteen personality Types. Thus, when you learn about Type Theory, you learn what occurs on the inside; in a person’s head and heart — and how they relate back-and-forth with others. No other personality theory can give you this picture.

This application is ideal for serious students of psychology. Learning about ourselves and others is not done by simply “taking a test” that “tells” us who we are. Although we include multiple personality assessments, genuine learning for adults involves continual exploration and reflection. This application gives you tools; you the one who brings the curiosity and patience for discovery.

This application is the work of renowned Type Theorist and UCLA lecturer Dario Nardi, PhD, author of numerous books on personality psychology, cognition, neuroscience, and self-leadership. Dr. Nardi has worked with many other experts, including practicing organizational development consultants and psychologists. What you get is the product of many minds and personalities, not just one.

Just in Will i am ,

Update plz

This app need updating. To mention a few problems.... Crash's periodically. Test results unchanged from pervious tester even thou new person is added. Its so frustrating and embarrassing when that "new person" takes the test giving each question consideration and thought. When the tester gets to question 19 *FLASH* they are blown out to the home screen.... Even thou there are issues its a great app! Would otherwise be five 🌟 in my book. Is there going to be an update anytime soon? I do hope so... its a great app but there are problems.

Great app for those exploring MBTI. Thanks for the update! Looking through it again after all this time and still learning from it.

Great overall, needs a bit of copyediting

I really love being able to take the MBTI in my pocket. I speak in Myers-Briggs shorthand with a few of my friends, and this gives us another way to interact with one another.

I love the feature where you can place two personality types in contrast to learn how to communicate more effectively with people who may see the world from a different angle. I haven't seen anything like this in the past.

My one critique is that the NT types and NF types get switched in a few of the deeper analysis parts of the app. This needs to be fixed in an update.
