About this app

Get health data two ways:
1️⃣ Track health factors independently
2️⃣ 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!

Downloaded the app, first was unable to load any studies whatsoever - kept getting a "something went wrong" error. When tried to go to put feedback in the app - also errored. After a day the studies were able to finally load, however was not actually able to join any of the studies because after filling out all the info and being eligible to participate the app just got stuck on a loading screen. Will be happy to update the rating once the app actually starts working.

Love the concept of the app and the studies seem interesting but am having trouble actually logging into the studies, sometimes I open the app and it won't even load them other times I can see them, get past the questions and consent that determine eligibility but then it says error joining study, I don't get any further access to the study, no updates or notifications showing an activity for the study and in most cases it makes me go back through all the questions and consent all over again
