Join Studies. Track Your Health. Get Personalized Results.

Get health data two ways:
1) Track health factors independently
2) Join a study
Or do both!

Health factors you can track without having to join a study:
* Anxiety
* Depression
* Stress
* Mood
* New scales are added regularly!

If you prefer to join studies, we have a range for you to choose from:
* Microdose.me - The largest mobile microdosing study in the world. Led by Paul Stamets and a global team of scientists.
* Mental Health Tracker - Ever wonder if your mental health is affected by a new routine or treatment regimen like light therapy, mindfulness, or a new medication? Find out with our tracker.
* Sobriety and Well-being - Through a series of simple tests, daily check-ins, and optional wearable sleep data, we aim to find out how sobriety from alcohol affects sleep quality and dream recall.
* Gratitude Study - Led by Louie Schwartzberg, we explore “visual healing” and ask: does watching films about gratitude correlate with improvements in well-being?
* More studies in the app!

How It Works
1) Download the app and join as an anonymous participant – we won't ask for your name or email.
2) Answer questions, watch videos, and play game-like tests. Easy!
3) Automatically track your steps, sleep and more by connecting Apple Health and your wearables.
4) Receive rich health insights at the end of a study and improve your health along the way.

What to Expect
* Complete Privacy - We're committed to data privacy, encryption, anonymity and transparent policies. No sign up, no email, no Facebook connection required.
* Top-Quality Research - Our studies are rigorously designed with scientific protocols to produce credible findings.
* Personalized Health Insights - See your health trends and patterns whenever you complete a study. Compare your data anonymously with other participants. The more studies you join, the more you learn about yourself!

Good. A few bugs

The app is easy to use. I find the questionnaires and tests well explained. There’s a bug on one of the tests where if you select one of the options “I don’t remember,” etc, you are then prevented from tapping on the box to enter a number. Also, the feedback section of the app gave me an error.

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.
