“It's the first health app that doesn't make me feel anxious. It just quietly helps me notice patterns in my sleep and mood that I was too busy to see myself.”

Your health data.
Your choices.

We designed Carthalis around respect for your boundaries — and honest limits about what wellness software can do.

Your data stays yours

Your wellness picture is yours to keep, export, or delete. We do not sell your personal health information to third parties.

Add what you want, when you want

Sync a wearable, answer a check-in, upload a lab, or start with a conversation — the app meets you at your level of engagement.

Research and insights, not diagnosis

We provide research-backed tools and insights to help you understand your body — not medical diagnoses or treatment plans.

Not for emergencies

Carthalis is a companion for proactive wellbeing. For urgent symptoms or emergencies, contact local emergency services or your clinician.

Common questions

Carthalis is a personal health companion that helps you build a full picture of your health and wellness from conversations, uploads, surveys, and optional device data. After you share what you have — a question about a symptom, a lab result PDF, a quick check-in, a meal or bowel movement log, or wearable data — Carthalis turns it into a daily coaching plan with insights and actions across fitness, nutrition, recovery, and longevity. You can connect a wearable any time, but it is never required. Carthalis keeps your data under your control and ownership, never sells it to third parties, and only shares it with your explicit consent. Carthalis provides research-backed wellness education and tools, not medical diagnosis or treatment, and is not designed for emergencies — always seek professional care for urgent or clinical decisions.
