Let's figure this out together. How has your sleep been, and have you noticed any changes in your diet or stress levels recently?

Expert

Personalized to your life

Connect Apple Health and your guidance reflects how you actually sleep, move, and recover. The more it sees, the sharper it gets.
Private and secure conversations

I'm trying to better understand my celiac disease. Where do I begin?

Great, it's time to reclaim your life. Celiac disease can be very challenging, but there are a lot of ways I can help. When did you receive your diagnosis?

Your vault. Yours alone.

Onix encrypts everything and stores it on your phone. No one other than you sees your conversations. Ever. This is not a privacy policy. It is the architecture. Built in Montreal under the strongest privacy laws in North America. Designed so there is nothing to hand over, even if someone asks. Finally, the freedom to be honest. It is what makes Onix work.
A personalized health journey plan

Journeys, not just conversations

Some challenges need a roadmap, not just a reply. Your Journey is a living, personalized plan. It adapts as new information comes in and checks in when life gets in the way.

With privacy comes memory

Most apps forget you the moment you close them. Onix remembers. Every conversation builds on the last, so you never have to start over or explain yourself again.
Multiple experts working around your unique profile

Multiple experts. One you.

Your health doesn't fit one specialty. Onix connects you to experts across longevity, nutrition, mental health, and more. Each one sees the same you.

Built on real expertise

Each expert trains their onix on their life's work. Knowledge no other AI can access. The real thing, not a chatbot impression.

" After almost 30 years of being dismissed about my thyroid, McCall's onix coached me exactly how to advocate for myself. My doctor did a complete 180, and I can't imagine that outcome without McCall and Onix. "
