## Quantified Citizen Description
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
* ADHD
* 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!

## Quantified Citizen Reviews in United States

### **--- "Good concept, poor execution"
I really enjoyed the study I took. However, there are several major errors that caused this 2 star review

1: despite notifications being on, I was never notified about new surveys being available and missed deadlines as a result. 

2: the feedback option is broken and unavailable 

3: finished my study about 2 months ago and still haven’t received results as of the date of this review 

4: reached out to support team and never received a response. 

- the lack of results and response from support team made all that time I invested into the study definitely not worth it.
-- Bighoss2211, 2024-11-05

### ****- "Bugs/Glitches"
The app is a wonderful idea, and I think it’s all very well done. The problem I personally am experiencing is two-fold: 
1) despite all the notification settings being turned on, it won’t tell me when the questionnaires become available, nor when they are about to expire. 
2) the feedback option in the app, the place to relay this problem to the developers, doesn’t work for me. It comes up with a failure/error message.

I don’t check this app as often as is required to fill out the questionnaires. It doesn’t say how often the questionnaires appear (weekly? More? Idk), and I never get a notification. Please fix that glitch.
-- Michael Naz, 2024-08-06

### ***** "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.
-- kasilubo, 2024-04-21

### *---- "App doesn’t work for me"
Try to sign up and get “Sign up error |  please, check internet connection and try again”   Internet is obviously working because I’m able to leave this review…
-- Garkleflint, 2024-04-20

### *---- "App broken"
Never works. Always get an error upon setup
-- Fawniqua, 2024-04-16

### *---- "Error"
Expect
Last question on demographic survey for microdose.me to display a question

Actual
Blank screen and unable to complete survey. Tried force closing twice and restarting survey. iPhone X. Latest version.
-- alexappletime, 2024-04-16

### *---- "Tap test = awful"
The two test is incredibly unresponsive to all taps and only registers them if you slowly tap between the two circles. It will lag a bunch and won’t count any taps if you go as fast as you can. Seems incredibly inaccurate if you ask me. Fix the lag in the taps.
-- cpearson14, 2024-04-15

### *---- "Face ID broken"
Was looking forward to using the app but it gets stuck in a David checking loop in multiple spots and makes the app unusable even after completely closing and reopening
-- Jeremiah-, 2023-01-10

### *---- "Totally useless after update"
How frustrating to have an app that’s designed for daily use/tracking and now I only get an error message (despite uninstalling/reinstalling and all other tips mentioned).  I’ve been completely unable to access anything since the update and about to quit trying and find another app with a reliable backup!  The error message says:  type “bool” is not a subtype of type ‘iterable<dynamic>’.
-- AuroraDelta, 2022-11-27

### ***** "Super interesting studies"
Very happy to be contributing information that will hopefully yield positive findings on plant medicine treatment for anxiety and depression.
-- Meggan 71, 2022-11-10
