Best App I’ve ever purchased

I recently downloaded the work app and I was pleasantly surprised at how easy it is to use and interface with.
It makes doing The Work simple and accessible, which is the best for when strong emotions and fearful thoughts arise.
I love it! Anytime I’m stressed out it’s so easy to just pull up the app on my phone and do The Work for 5-10 minutes and finish feeling like a completely different person then I was before. It makes doing The Work more do-able.
I highly recommend purchasing the app, it’s worth way more then the cheap .99¢ cost.
I can do The Work anywhere now, without having to have a paper and pen in hand.

Accelerates the Work tremendously

The app works very well on my phone. I can see it is constantly being improved by reading past reviews and seeing what it actually does today. I use it daily and it’s getting more and more effective for me.

Having this at my fingertips makes it possible to inquire anytime. That’s the point, constantly chipping away at false beliefs and mental misconceptions that cause my pointless suffering. This makes it simple, there is no excuse not to spend a moment and work a thought, explore any troublesome state of mind or body. It is always helpful and I’m beginning to naturally inquire this way as Katie describes with the practice this app provides. The questions are becoming part of my thinking process and my insanity is easing. There is a history log so I can see where I’ve been, how silly past unexamined thinking was. I see my progress and it encourages me, I directly experience moving towards joy and freedom. Best mental health bargain I know.

Great application, minor qualm

I love almost everything about the application. It’s convenient, it’s easy to use, practical and full of everything I’d need or want in a virtual journal for The Work. The only thing that irritates me: how the JYN worksheet’s what do you think of that person always auto scrolls to the very end of where the text ended, even if the cursor is in the very beginning of the text. This is very inconvenient when I want to change something in the beginning, because I cannot see what I’m doing. Only the end of the text is visible. Please change.

Otherwise, it’s great. Thank you.
