How it works

A clear picture on day one. Real help over time.

Tell us about your health and see your picture on day one. Over the weeks, Carthalis helps you focus, act, and carefully learn what affects you — always with your say.

  1. Day one

    Tell us about your health

    Your goals, symptoms and conditions — then snap a lab result, take a quick check-in or log a meal. Connect your devices (optional).

    Start with whatever you have

    • Your goals, symptoms and conditions
    • A lab photo or PDF
    • A quick check-in
    • A meal, symptom or bathroom log
    • Apple Health, Health Connect or a wearable (optional)
  2. Day one

    Your picture

    Science-backed insights from day one — and a richer picture as you share more.

    A few answers about you and a lab result already give you a first picture.

    What to focus on first

    Your health report ranks what matters most across everything you share — with a next step for each.

    Top priorities

    1. 1Keep an eye on your blood pressure

      Insight

      It has crept up across your last four readings, from 128/82 to 136/88, and your salt intake has been high most days.

      Action

      Mention it at your next visit. Meanwhile, we'll track it weekly and suggest lower-salt swaps.

    2. 2Balance your push and pull strength
    3. 3More daylight, less late screen time
  4. Every day

    Help every day

    A simple daily plan, reminders and coaching — and careful investigation when something comes up.

    We notice what affects you

    Patterns in your own data — shown only when your data supports them. Four examples here; it works across everything you track.

    We noticedSample data

    7 of your last 9 migraines followed a short night and a drop in barometric pressure.

    • Migraine
    • Short night
    • Barometric pressure drop

    From your check-ins, sleep and local weather

  6. Your call

    You choose what to check

    Nothing starts on its own. Clinical findings go to your doctor — never a self-check on medication.

    A check for youSample data

    Want to check whether protecting your sleep before low-pressure days makes a difference?

    Six weeks as usual, then six weeks where we nudge an earlier bedtime the evening before a forecast pressure drop.

  7. After the check

    See what helped — and tell us

    Honest results from your own numbers. Your answer shapes what comes next.

    Your resultSample data

    During the check2

    2 migraines during the check, 6 in your usual weeks. A real pattern for you — not proof sleep is the cause, and the numbers are still small, so we'll keep watching.

Common questions

Carthalis is a health companion. You tell us about your health, add lab results, check-ins and logs, and connect your devices (optional) — and get a picture of your health on day one, with 140+ science-backed educational insights. It helps you focus on what matters first and supports you every day. As weeks pass, it notices patterns in your own data and lets you choose what to check. We will never sell your health data. Wellness education, not diagnosis.

Create a free account and answer a few questions about you and your goals — it takes a few minutes. Add a lab result, a check-in or a log whenever you like, and connect a device only if you want to. Your first picture appears on day one.

Not to start — but we encourage it. Connect Apple Health, Health Connect, a wearable or a glucose monitor (optional) and your picture gets richer: sleep, recovery, activity and glucose patterns that are hard to see any other way. Until then, Carthalis works from what you tell us about your health, your lab results, check-ins and logs.

We only show a pattern when there is enough of your own data on both sides to see a clear difference. A pattern means things seem linked for you — not that one causes the other. You choose whether to check it, and results are reported honestly, including when nothing changed.

No. Carthalis provides wellness education and coaching to help you understand patterns and plan next steps. Medication interaction checks are informational — discuss them with your provider. It is not for diagnosis, treatment or emergencies.

Your health data is never sold — not on its own, and not as part of selling the company. If Carthalis ever joins another company, your data only moves with the service, to a company that has agreed in writing to keep every promise in our privacy policy; otherwise it is deleted. We'll tell you at least 30 days before, so you can download or delete everything first. If Carthalis ever shuts down, you'll get at least 60 days to download your data, and then we delete it.
