Awesome App! Thank you so much Mr. Dalio!!!

Runs smoothly. Great user interface. Most importantly it makes me better. The coach finds answers to life’s problems on a daily basis and teaches you how to better handle challenges. These situations can be saved so you can begin to see how certain principles are more important for you to focus on or find your own answer to. Ray Dalio’s commitment to giving back later in life is actualized in this app by helping us all make better decisions each day. In addition he also provides access to his extensive writing on economic theory in his perspective which is also extremely insightful.

Makes Material Convenient

This really makes digesting Ray Dalio’s lessons convenient. The app remembers where you left off in the books (which also contain extra media) you also get case studies for these principles as if you were a Bridgewater employee.

Honestly, the five star rating really goes to the Coach feature included. I’d say that is the most valuable tool as the app can personally give you principles that would help you gain clarity and resolution to your most pressing problems. Fantastic stuff, I am extremely grateful.

Fantastic value!

I have been following Ray Dalio for several years now and read both his books. When I heard about this app I right away downloaded it and have been amazed how much solid value I have received from it. Thank you Mr. Dalio for sharing your lifetime of experience with the next generation. I am a business owner and your expertise is a valuable part of my long term strategy. I recommend your book and app to all of my friends who are hungry for learning!
