The Facade is Finally Being Revealed

This app explores the medicinal and overall beneficial side-effects of psilocybin, but it is more about improving the collective health of it’s users. By contributing to this app’s research, there will be more information to make mushrooms legal for the people that need them- as well as a self boost in mental and physical stimulation due to participating in the study.

The idea is good but

The app seems to have a lot of bugs and does not flow well. Doesn’t allow you to fill out missed tasks and now I’m locked out from being able to further participate for an unknown reason. I really like the idea of what this study is trying to do and really want to help support it but the app itself doesn’t function well for me. The gratitude videos serious are really nice. I think once the bugs are worked out and the app is more user friendly I think a lot of great change can be made.

Developer Response ,

Thank you for your thoughtful review. We have fixed the bug that caused some users to be locked out of tasks in the next release and it will be available shortly (v.1.2.5). Feel free to reach out to us here https://quantifiedcitizen.com/contact-us/ with additional bug reports and suggestions. We've got a lot of great features planned so we can fulfill the potential of this idea.

Very Buggy

I am 2 weeks into a trial. The app is very buggy, which will bias results. This morning I got 3 duplicate push notifications. Everyday, it says I missed yesterday’s period, but I have only missed one day so far. I check in roughly the same time everyday. Today it showed me a bunch of new tasks, but the are all red and won’t allow me to do them. It took me 9 days before I realized there is a back arrow to correct accidental data entry. A great idea with. Lot of promise, but data isn’t trustworthy until UX fixes are made. Should have a baseline trail to measure accuracy.

Developer Response ,

Thank you for this detailed feedback. We have another release coming out soon that fixes some scheduling bugs, and will work on making the notifications be more concise and trustworthy in the release following that.
