Research at Carthalis
Research that sees the whole person.
Most studies see one slice of health — a lab panel, a wearable or a survey. Carthalis brings many kinds of data together, with consent, so research can ask questions single datasets can't. Taking part is always your choice.
Questions single datasets can't answer.
How do sleep, meals, labs, symptoms, activity and environment affect each other — for real people, over months? Answering that needs many kinds of data from the same people, shared on purpose. That is the research Carthalis is being built for.
You choose whether to take part, you see what's shared before you join, and you can stop any time. We will never sell your health data.
- Sleep & recovery
- Meals & nutrition
- Lab results
- Symptoms & conditions
- Activity & fitness
- Mood & stress
- Medications
- Environment
Our research approach
Joining research means choosing to contribute to health science while you use Carthalis — never turning you into a data product. Participation is voluntary and transparent, you can stop at any time, and every part of Carthalis works the same whether you join or not.
Carthalis is a wellness companion first — not a pharma recruitment portal or clinical trial platform. Research sits beside your everyday health picture, with clear consent before anything is shared.
Voluntary
Carthalis research participation is optional. You can use every part of Carthalis without joining any study.
Transparent
Before you opt in, Carthalis explains purpose, scope, and who can access contributed data — separate from everyday app use.
You can stop any time
You can change your mind and stop at any time — no new data is shared after you do. Research sharing is a distinct voluntary choice aligned with data ownership — not a condition of signup.
What voluntary participation looks like
When you choose to participate, Carthalis may invite check-ins through the same daily home you already use — validated wellness surveys and study Pulse cards when enrolled. These support self-reflection and coaching context, not medical diagnosis.
Validated wellness surveys
PSS-10, PHQ-9, GAD-7, and related assessments on Pulse support self-reflection and coaching context — wellness education, not diagnosis.
Study Pulse cards when enrolled
If you join a program, study-specific check-ins may appear on your daily home — invitations only, never automatic enrollment.
Never required for the core product
Contributing to research is never required to use Carthalis. Health research opt-in is always your choice.
When studies are available
- Study invitations may appear on Pulse when you are enrolled in an approved program — there is no public study catalog on this page.
- Signing up for Carthalis does not enroll you in any study. Carthalis research participation starts only when you choose to learn more about an available program.
- For research teams evaluating cohort dashboards and admin analytics, see our page for studies — a separate path for operators, not automatic enrollment for app users.
Methods and instruments we build on
Carthalis uses established, validated instruments in the app for educational wellbeing context — paired with wellness education, not diagnosis. We do not list unverified publications or trial outcome statistics on this page.
| Instrument | Purpose | Wellness framing |
|---|---|---|
| PSS-10 | Perceived stress self-reflection | Coaching context — not diagnosis |
| PHQ-9 | Mood and wellbeing check-ins | Educational screening-style — discuss with your provider |
| GAD-7 | Anxiety-related self-awareness | Wellness education — not clinical certainty |
