How Vora Thinks
About Your Data
Health data is messy. Your devices disagree with each other. Measurement methods vary wildly. Most apps ignore this complexity and display raw numbers. Vora was built from the ground up to solve it.

Same night. Three devices. Three answers.
The Data Conflict Problem
Every wearable uses different sensors, algorithms, and sampling rates. When you track with multiple devices, their data inevitably conflicts. Here is what Vora does about it.
Weighted by measurement context: Oura overnight continuous, Apple Watch spot checks, Garmin activity-adjacent.
DATA RECONCILIATION
Your Devices Disagree. Here is Why That Matters.
Your Apple Watch measures heart rate optically from the wrist with green LEDs. Your Oura Ring does the same from the finger with infrared. Different wavelengths, different vasculature, different motion artifacts. They will never perfectly agree.
Vora does not pick a favorite. It weights each source by measurement context, sensor quality, and time-of-day reliability to produce a reconciled metric that outperforms any single device.

Weighted: Oura (sleep onset accuracy) + Apple Watch (wake detection) + Garmin (deep sleep staging)
SLEEP DETECTION ACCURACY VS POLYSOMNOGRAPHY
Based on published polysomnography comparison studies. Multi-source reconciliation improves accuracy by reducing device-specific bias.
SLEEP ACCURACY
How Accurate Is Your Sleep Data, Really?
Consumer wearables detect total sleep time with 78-91% accuracy compared to clinical polysomnography. That sounds decent until you realize a 10% error on 8 hours is 48 minutes - enough to completely change your recovery assessment.
Each device has predictable failure modes. Oura overestimates sleep for still-but-awake periods. Apple Watch misses brief awakenings. By combining sources and accounting for these biases, Vora reduces total sleep time error to under 12 minutes on average.
HEART HEALTH METRICS
RHR, HRV, and What Your Wearable Actually Tells You
Heart rate variability is not one metric. RMSSD, SDNN, and pNN50 each capture different aspects of autonomic function. Your Apple Watch reports one, your Oura reports another, and they measure at different times of day with different algorithms.
Vora normalizes across HRV calculation methods and measurement windows to produce a consistent trend. Your resting heart rate is reconciled from overnight continuous monitoring (Oura) and daytime spot checks (Apple Watch) to show genuine fitness trends, not sensor noise.

AI COACHING ENGINE
From Raw Data to Daily Decisions
Most health apps show you charts and leave interpretation to you. Vora takes a different approach: it processes your raw wearable data through a multi-stage AI pipeline that accounts for your sleep quality, training history, stress markers, and recovery state.
The result is not a generic recommendation. It is a set of daily decisions calibrated to where you are right now, what you did yesterday, and what your body is telling you today.
NUTRITION AI
Computer Vision for What You Eat
Manual food logging is tedious and error-prone. Vora uses computer vision to identify foods from a photo, estimate portion sizes, and calculate macronutrient breakdowns without requiring you to search databases or weigh ingredients.
The model recognizes thousands of foods including mixed dishes and restaurant meals, then cross-references with your metabolic data to show how what you eat affects your energy, recovery, and body composition over time.

TRAINING LOAD - 4 WEEK VIEW
Acute:chronic workload ratio calculated from daily training stress scores across all activity types.
TRAINING LOAD
Preventing Overtraining and Undertraining
Training too hard leads to injury and burnout. Training too little leads to stagnation. The difference between productive strain and overreaching is surprisingly narrow, and most people only discover they crossed the line after the damage is done.
Vora tracks your acute-to-chronic workload ratio across all activity types, combining training data with recovery signals like HRV, sleep quality, and resting heart rate to keep you in the productive zone where fitness gains actually happen.
Data in. Intelligence out.
Most health apps treat data ingestion as a plumbing problem. Connect the API, pull the numbers, display them in a chart. Vora treats it as an intelligence problem. When your Apple Watch says one thing and your Oura Ring says another, the answer is not to pick a winner. The answer is to understand what each source measures well, reconcile the conflicts, and build a picture that is more accurate than any individual device could produce alone.
“The more devices you connect, the smarter your data gets.”
That is the opposite of how most apps work, where more sources just means more noise.
