Billionaire Ray Dalio manages the most successful hedge fund on the planet - and he can now be your personal life coach.

Principles in Action is a free app designed around Dalio's 2017 book "Principles," which has sold over 2 million copies worldwide. The app not only has a full copy of the book, it's peppered with videos, koan-like career advice, and general pearls of wisdom collected from the writings of the Bridgewater Associates chief.

Dalio founded Bridgewater Associates in 1975 out of his Connecticut home. Since then, it's become the world's most successful hedge fund, with $150 billion in total assets under management.

One of Dalio's core principles is having "radical transparency," or total openness, within his company. This gave him the idea for his first app, Dots, which let employees rate each other on a 1 to 10 scale live during meetings.

There's no live monitoring going on in Principles in Action, but you do have the chance to step inside the mind of Ray Dalio through his books, meetings, and speeches. We took a look at the app and highlighted some of its more interesting features.
