Impressive Customer Service/Response Time

I had initially rated this as 1 star but I am here to update it to 5 because of the incredible customer service/response time regarding my issue. I sent an email to report the bug and they (a founder, no less!) quickly responded to my concerns. While my data lost was not recovered (and I’m not entirely sure this wasn’t user error), they made the proper steps to update the app so it’s less likely to happen again.

Looking forward to using this app a bit more, and knowing this developer is ready, eager to address all issues to make this app work in the best way possible. kudos!

Original post:
Post-dated entires disappear with no warning

New to app, so still getting to know it. However, don’t try to post-date a journal entry! I wrote my best journal entry to date around midnight and post dated it to hit the previous day. I followed the prompts as usual to the end. Went to go find it today to find IT DISAPPEARED. It doesn’t show up in my history, and I wasn’t prompted the journal entry wouldn’t be saved. Was able to reproduce this issue by selecting an earlier time than the current time. Please fix this, I am very disappointed I lost my work, both written and the self-work/reflection I intended to make with this last entry. 😢

Truth vs. Lies

I’ve suffered from depression and anxiety for years. I found out about this app from a therapist, and over time it became a transforming lifestyle when I invested my time into it. Thoughts can be so convincing and seem true and emotions can be so controlling. This app opened my eyes to what was really going on so I could be in control of my thoughts and not the other way around! I have combined this app with therapy and medication and after years of challenges and growth I can see how far I’ve come from previous entries that I can look back on. Now I can also point out when the same cognitive distortions that affect me, come out in what other people say in conversations. It looks like A LOT of people could use this from what I can tell with recent events happening.

Well Made and Helpful

I did not really think that this app would help me because it’s so hard for me to change the idea that all of my thoughts aren’t true. Therefore I didn’t think CBT would help me.

However, after working with this app for several weeks, I can see the value in it. It’s very helpful to be able to go back and think about my past entries and how it has or hasn’t changed me. Just the act of thinking about these CBT entries helps me see destructive patterns.

I like the way that you can search under different categories, search by mood, etc. I originally thought there was a flaw in the search function, but after contacting them, they fixed the problem! So they do listen to feedback.
