Coach, not chatbot

The difference between asking a question and being coached.

A chatbot waits for you to ask. A coach shows up, follows up, and holds you accountable.

Generic chatbot
Is my cholesterol high?
Normal LDL-C is generally considered below 100 mg/dL for most adults. However, optimal levels may vary depending on your risk factors. You should consult your doctor for personalised guidance.
You ask. It answers. You forget.
Ryn, unprompted

Ryn
Your LDL-C has been climbing since January. 112 to 138. Your ApoB is also trending up. Worth raising with your doctor at your May appointment. Here is what to ask.
Ryn reaches out. Remembers. Follows up.
How it works

Set up in five minutes. Coached from day one.

Ryn learns your goals, your history, and what matters to you. Every conversation adds context. Nothing is forgotten.
03

A personalised protocol built on your data and your goals. Not a generic template. Updated as your numbers change.

Ryn shows up daily
Check-ins, follow-ups, and adjustments delivered right in WhatsApp or Telegram. You never have to remember to open an app.
Your full picture

Ryn does not just track data. Ryn connects it.

The differentiator is not that Ryn connects to Apple Health. It is that Ryn synthesises across sources, across time, and tells you what it means together.

61+
Health markers tracked
Metabolic, cardiovascular, hormones, body composition, sleep, and nutrition. The markers that actually predict how you will feel and perform.
PDF
Lab result extraction
Upload a blood work PDF. Ryn extracts every marker automatically, tracks it over time, and tells you what changed and what it means.
∞
Cross-channel memory
WhatsApp, Telegram, or the app. Ryn remembers everything across every channel. No starting over. No re-explaining your history.
Workouts and activity
Apple Health and Strava data synthesised. Training load, recovery trends, and programming that adapts to what you actually did.
Body composition
Weight, body fat, lean mass. DEXA scans, scale readings, and the trends that matter over weeks, not days.
Conversations
Everything you tell Ryn becomes context. Symptoms, goals, preferences, schedule. It all builds a picture no generic AI can match.
One coach, six areas of expertise

Specialist depth. One voice. Zero navigating.

Six specialist areas work in parallel behind a single coaching relationship. You always talk to Ryn.

Fitness and Training
Structured programs, progressive overload, accountability. Ryn builds your training plan and adjusts it as you go.
Nutrition
Performance fueling, not diet culture. Timing, targets, and what actually moves the needle for your body.
Sleep and Recovery
HRV, sleep stages, recovery patterns. Ryn spots what is affecting your energy before you do.
Longevity
Long-term metabolic health, cardiovascular fitness, and the data that shows where you are headed.
Hormones and Metabolic Health
Thyroid, cortisol, insulin sensitivity, testosterone. The markers most coaches miss but that drive how you feel every day.
Mobility and Movement Quality
Range of motion, movement patterns, and the stretching work that prevents injury and supports training.
See what Ryn knows
Built for accuracy

Every response is checked before you see it.

No other consumer health AI validates its own answers in real time. Ryn does. Every response passes through a validator that checks for accuracy, unsupported claims, and potential risks.

Real-time response validation
Every response is checked for medical accuracy, unsupported claims, and potential risks before it reaches you. No other consumer health AI does this.
Evidence-tiered guidance
Ryn signals the strength of the evidence behind every claim. Established science, emerging research, or anecdotal. You always know what you are working with.
Ryn knows its limits
Ryn is a health coach, not a doctor. Ryn will not diagnose or prescribe. When clinical input is needed, Ryn says so and tells you exactly what to ask for.
Your data stays yours
PIPEDA-compliant. Encrypted at rest (AES-256) and in transit (TLS 1.3). Your health data is never sold, never shared, never used to train AI.

What people are saying.

“Ryn caught a pattern in my HRV data my Oura app completely missed. Three weeks of training stress showing up as sleep issues. I thought I had insomnia.”

Beta user
Physician, Toronto

“It is the first health tool that actually meets me in WhatsApp. I do not have to remember to open an app. Ryn just shows up when it matters.”

Why not just use ChatGPT?
ChatGPT is an encyclopedia. Ryn is a coach. An encyclopedia waits for you to ask. A coach shows up, remembers, follows up, and adjusts your plan. That is the difference.
Is my data safe?
Your health data is encrypted at rest and in transit. It is never sold, never shared, and never used to train AI models. PIPEDA-compliant. You can export or delete everything at any time.
What if I want to cancel?
