Absolutely incredible

I never feel the need to write reviews, but right now I think I need to. I have only been using this app for a day, and can tell that this will be my safe place to spill my thoughts down feeing and analyze what is going on. I have done CBT in the past, but it’s been hard to make it to my appointments because of my hectic and overwhelming schedule.
If you are struggling with invasive thoughts, anxiety, depression, etc. you need this app!! I feel better after every entry, and I love the check ins that I can do throughout the day. Thank you for creating this app!!

Great app, bad pricing model

This app is exactly what I need to help me develop good thinking habit and stay positive in my life! I also recommended it to my therapist hoping this can help others.

However I don’t feel right about how the dev prices it. Of course you don’t have to pay for it; the free version has all the basic functionalities for your CBT record, but it happens that I need to share my thought entries with my therapist, which is locked until you pay. You need to pay almost 40 bucks a year for the record export, and this is kinda ridiculous.

I would rather pay upfront for one time cost and that’s it. I hope the dev can reconsider how they charge users for this app. It’s a solid app, and I would like to support a solid developer who really cares about mental health. But so far the pricing is not quite right.

Developer Response ,

Thank you for your feedback. We hope that you and all of our users who need premium features can afford $3 / month (roughly the cost of a cup of coffee and half the price of other similar apps). If this is not possible, please reach out to us via email! :) We're proud to offer nearly all features of this app for free so we can help the most amount of people.

Amazing mood changer

When I remember to use this tool to challenge and defeat my negative moods and thinking I generally have amazing success. I can really change my experience at any given time by picking this up and applying the thought changing exercises. So many times through life I have heard the idea that it is how we view events that culminates our experience of an event and yet it seems so natural to just accept my default perspective. In fact this is the tool that can help me re-view events for a better one.
