How we build Omnio — health data infrastructure, MCP servers, time-series analytics, and the AI layer that ties it together.
When to Trust Your Health Score: Confidence, Cross-Validation, and the Limits of Wearable Data
Composite health scores fuse many inputs into one number — but only if you know which inputs are trustworthy. Confidence, cross-validation, suppression.
Body Composition: DEXA vs Smart Scales vs Calipers
Your bathroom scale's body fat number is a guess with a ±5% error margin. Here's what DEXA, bioimpedance, and calipers actually measure, how accurate each is, and how to use them together.
How to Interpret Your Sleep Score Across Devices
A 75 on Oura is not a 75 on Garmin. Here's what each sleep score actually measures, which factors predict how you feel, and why consistency matters more than any single number.
What Is a Composite Health Score and Why Does It Matter?
Single metrics lie by omission. A composite score synthesizes HRV, sleep, training load, and recovery into one number — but only if you can see how it's built.
What Is ACWR and Why Does It Matter for Training?
The acute-to-chronic workload ratio is the single best predictor of training-related injury. Here's what it measures, where the 0.8-1.3 sweet spot comes from, how Omnio calculates yours, and the mistakes that get people hurt.
What Your Blood Work Actually Tells You About Fitness
Lab reference ranges are built for the general population. If you train seriously, most of your results need a completely different interpretation.
How Wearables Measure Stress and Strain — and What the Numbers Mean
Garmin Body Battery, WHOOP Strain, Oura Stress, WHOOP Recovery — these scores sound like they measure the same thing. They don't. Here's what each one actually calculates, why they contradict each other, and how to read them together.
What Is HRV and How Do Wearables Measure It?
RMSSD, SDNN, LnRMSSD — your wearable picks one and doesn't tell you which. Here's what HRV actually measures, how Oura, Garmin, WHOOP, and Polar each capture it differently, and why your baseline matters more than any single number.
Best Bevel Health Alternatives for Deep Health Intelligence
Bevel is a polished health dashboard with Oura and Garmin support. But if you want validated nutrition data, transparent scoring, or cross-domain correlations backed by statistics — here's what else is out there.
Best Cronometer Alternatives for Nutrition Tracking
Cronometer is the gold standard for micronutrient tracking. But if you want your nutrition data connected to sleep, HRV, and training — or a modern mobile experience — here are the best alternatives.
Best Levels Alternatives for Metabolic Health Tracking
Levels made continuous glucose monitoring mainstream. But CGM data alone doesn't tell the whole story. Here are the best alternatives for understanding your metabolic health.
Best MacroFactor Alternatives for Adaptive Nutrition
MacroFactor's adaptive algorithm is best-in-class for macro coaching. But if you want micronutrients, meal quality, or wearable-connected insights, here are the alternatives worth considering.
Best MyFitnessPal Alternatives That Understand Your Diet
MyFitnessPal counts calories. These alternatives track meal quality, micronutrients, and how your diet affects sleep, recovery, and training. Here's what to switch to.
Predicting Health Dips Before They Happen
Your wearable data contains early warning signals that precede readiness dips by 1-5 days. We built a system that learns which signals matter for you personally — and warns you before the dip arrives.
Your Body Already Knows When to Focus
Your wearable data contains a hidden signal: the ultradian rhythm. We're building a system that reads it — predicting your best focus windows from sleep data, then refining in real-time with a heart rate monitor.
Most Nutrition Trackers Count Calories. Ours Understands Your Diet.
Calorie counting is table stakes. Omnio validates your logs against government nutrition databases, scores meal quality, tracks 35 micronutrients and polyphenols, classifies your dietary pattern, and connects what you eat to how you sleep, recover, and train.
Why Connecting Accounts with OAuth 2 Doesn't Share Your Password
When you connect Oura, Whoop, or Withings to Omnio, you sign in on their website, not ours. Here's what OAuth 2 does, what we receive, and what we never see.
Your Calorie Target Is Wrong. Here's How We Fix It.
Most calorie calculators give you a number based on a formula from the 1990s and call it a day. Omnio watches what you actually eat, how your body actually responds, and learns your real metabolic fingerprint over time.
Your AI Health Assistant Doesn't Know Who You Are
Your AI health assistant analyzes your sleep, recovery, and training data — but it never sees your name, email, or account ID. Here's how we built privacy into the architecture itself.
Can Your Health AI Prove It Isn't Lying to You?
We asked Oura, WHOOP, and Omnio the same research question. Two gave vague platitudes with zero citations. One gave verifiable evidence. Here's why the difference is architectural.
Adaptive Training With Wearable Readiness Data
Omnio doesn't just track your workouts — it derives your training schedule, gates every session through biometric readiness, adjusts for nutrition, and learns from outcomes. Here's how we're building a genuinely adaptive training system.
Which Wearable Is Most Accurate? What 17 Validation Studies Actually Found
We reviewed 17 peer-reviewed studies comparing Oura, Apple Watch, Fitbit, Garmin, WHOOP, and Samsung across sleep, heart rate, HRV, SpO2, VO2 max, and more. Here are the specific numbers.
Why We Built a Bayesian Brain for Your Training Plan
Every fitness app says it 'learns.' We wanted to prove it. Here's why we chose Bayesian parameter estimation over neural nets, how six independent sub-models personalize your training, and why the system can never be worse than a textbook.
Your Wearable Says Rest — But Should You Actually Train?
Readiness scores tell you how recovered you are. They don't tell you whether skipping today's session is smart load management or the start of detraining. We added a sports science metric to close that gap.
How We Avoid Spurious Correlations in Health Data
When you test enough metric pairs, something will appear correlated by chance. Here's how Omnio's correlation engine uses detrending, dual methods, p-values, and FDR correction to separate real signal from noise.
We Asked Oura, WHOOP, and Omnio the Same Sleep Question. Here's What Happened.
Every major wearable now has an AI assistant. We asked all three to compare a week of sleep data. The difference in depth reveals a fundamental architectural gap.
Why We Built a Model Context Protocol Server for Health Data
Most health platforms treat AI as a chatbot skin over a database. We built an MCP server with a plugin architecture, time-series storage, and multi-step reasoning. Here's why.
How to Combine Oura and Garmin Data in One Dashboard
Using Oura for sleep and Garmin for training? Here's how to combine both data sources into one dashboard without duplicating metrics or losing context.
Garmin vs Oura for Recovery, Readiness, and Sleep
Garmin and Oura solve different problems. Here's how they compare for sleep tracking, training readiness, workouts, HRV, and whether you should use one or both.
Oura vs WHOOP for Sleep, Recovery, and Training
Trying to choose between Oura and WHOOP? Here's the practical difference in sleep tracking, HRV, recovery, workouts, battery life, and who each device is actually best for.
Best App for Polar H10 Heart Rate and HRV Tracking
Looking for the best app for a Polar H10 chest strap? Here's what to look for if you care about heart rate, RR intervals, HRV, ECG, guided readiness checks, and long-term trends.
