How It Works – velahealthai.com

The Vela Framework

Three steps. One result.

Every wearable brand is excellent at step one. Nobody else has built steps two and three.

📡

Track

YOUR WEARABLE'S JOB

Apple Watch, Oura, WHOOP, Garmin, Hume Band — every sensor, every metric, every night. They do this brilliantly. They capture the raw signal. HRV, sleep staging, strain, body temp, VO2. This is the input layer.

Synthesize

VELA'S INTELLIGENCE ENGINE

11 proprietary intelligence models run every night. They read every signal from every device alongside everything you log — nutrition, fasting, supplements, alcohol, subjective feel — simultaneously. They find the patterns none of your apps can find alone.

WHAT YOU RECEIVE

One spoken brief. Every morning. Before your day starts. Not a dashboard, not a score, not a chart. A directive in plain language — what your body needs today and exactly why. Delivered to your Watch or ears at 5am.

The Intelligence Engine

11 models. Running while you sleep.
One answer when you wake.

Each model analyzes a specific domain of your biology. Together they produce the compound picture no single model — and no single wearable — can see.

Wrist Temp Delta

Detects body temperature deviation from your personal baseline. Flags potential illness, inflammation, or hormonal shifts before symptoms are obvious.

Apple Watch Oura Ring WHOOP 4.0

HRR Decline

Heart rate recovery trend analysis. Declining HRR over consecutive days signals accumulated fatigue, overtraining, or cardiovascular stress — weeks before performance drops.

Apple Watch Oura HR WHOOP HR

VO2 Max Trend

Tracks estimated aerobic capacity over time. Declining trend against stable training load suggests recovery deficit. Rising trend confirms adaptation. Garmin provides the most accurate VO2 estimate.

Apple Watch Garmin Oura

Lag Correlation Engine

Finds delayed relationships between inputs and outcomes. Your wine on Tuesday affecting your HRV on Thursday. Your protein deficit on Monday showing in your recovery on Wednesday. This is the pattern finder.

Voice Logs HRV Data Oura WHOOP

Compound Deficit

Identifies simultaneous deficits across multiple domains — sleep debt + protein deficit + high training load — that compound into a risk greater than any single deficit alone.

Sleep Nutrition Logs Strain

Circadian Score

Measures alignment of your sleep timing, meal timing, training window, and light exposure with your individual chronotype. Misalignment is invisible on individual metrics but measurable here.

Sleep Timing Meal Times Weather / Sunrise

Cortisol Proxy

Estimates cortisol rhythm from HRV patterns, waking HR, sleep architecture, and logged stress. High cortisol proxy changes training, nutrition, and fasting recommendations.

HRV Sleep Staging Feel Score

Nutrition Recovery

Tracks post-workout and post-sleep nutritional replenishment. Identifies whether food logs support or undermine the recovery your biometrics are trying to achieve.

Nutrition Logs Active Calories Kilojoules

Sugar-Insulin Impact

Estimates insulin load from logged carbohydrate and sugar intake — then correlates against HRV, energy, and recovery quality to identify metabolic response patterns specific to your body.

Food Logs HRV Readiness

Alcohol Recovery

Quantifies the residual metabolic impact of logged alcohol across a 48-hour window. Maps exactly how last night's drinks show up in this morning's HRV, sleep efficiency, and recovery score.

Alcohol Logs HRV Body Temp Recovery %

Training Recovery

Synthesizes training load, strain scores, sleep quality, nutrition availability, and HRV into a single training directive — how hard to go, what zone, and for how long. Works across all wearables.

Data Sources

Every signal that matters.
From every device you already own.

Vela reads data from Apple Health automatically. Connect Oura or WHOOP directly in Release 2 for proprietary scores. All devices supported on day one.

Morning Brief Anatomy

Everything your brief contains.
Every morning. Spoken.

The brief is generated from all available data every morning at 5am. It runs whether you open the app or not. Your Watch plays it. Your phone plays it. 60 seconds. Everything you need.

VELA MORNING BRIEF — STRUCTURE Pre-rendered 5:00 AM · ~60 seconds

RECOVERY STATUS

HRVSleepRHRTemp

TRAINING DIRECTIVE

RecoveryStrainWeather

What to do today — zone, intensity, duration. Built from recovery status, yesterday's training load, fasting window, and today's weather. Not a general recommendation — a specific directive.

NUTRITION PRIORITY

Food LogsMacrosFasting

Yesterday's macros vs. targets. Protein deficit or surplus. Fasting window status. First-meal recommendation. Exactly what to eat first and when.

WATCH FLAGS

Anything the intelligence layer flagged that changes today's picture. Residual alcohol impact. Supplement timing. Illness signal. Temperature deviation. The things you need to know that your wearable app will never surface.

TODAY'S PRIORITY

All Models

One to three sentences. The compound synthesis of everything above. What matters most today. What to protect. What to do. Spoken clearly. No ambiguity.

Coach Platform

Your coach now sees everything your wearable tracks.

Personal trainers, performance coaches, and dietitians get a web dashboard that shows every client's biometrics, device data, nutrition logs, and Vela brief — in one view. They can override briefs, assign protocols, and set alerts.

Brief Override (5 types): Intensity shift · Nutrition focus · Recovery day · Protocol note · Custom message

Alert system: HRV drops below threshold · Illness signal · Missed protein streak · Any device readiness below 50

Device visibility: Coach sees Apple Watch, Oura, WHOOP, Garmin data for every client in one unified view
