Track Your Health. Join Studies. 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!

Very buggy app

I signed up to participate in a study and while it worked for the first month, now when I open the app it asks me if I want notifications, and regardless of my answer, the study is not accessible. The error detail is “Http status error [401]”.
The app hasn’t worked for over two months now and even after reporting the error initially, I received no feedback from the developer. I installed the recent update, restarted my iPad, and still the same error.
Considering all of the personal information the app collected, this is very disappointing and I’ll be withdrawing from the study. It could have been really useful!

Won’t let me sign up

Won’t let me sign up
Edit: still says my email has already been used even though I haven’t entered it or ever signed up yet. It won’t let me proceed past agreeing to the privacy policy.
