Fitaos Health Technology
Every Health Feature, Explained
From air pump blood pressure and ECG to EDA emotion detection and BIA body composition — explore the science behind each Fitaos health technology, how it works, where it applies, and what it means for you.
Our Technology, Our Promise
The Health Technology We Build Into Every Fitaos Device
Fitaos began with a simple frustration: the wearables on our wrists could count steps, but they couldn't tell us anything real about our health. Heart rhythm, blood pressure, stress and recovery — the signals that actually matter — were locked behind bulky clinic equipment or premium gadgets.
So we asked a harder question: what if the full picture of your heart, blood and body could live on your wrist — all day, effortlessly, without a single needle or cable? That question became our mission, and it shaped the technology portfolio we now build across our product line: oscillometric blood pressure driven by a precision piezoelectric air pump, a single-lead ECG chip that reads your heart's rhythm in 30 seconds, multi-channel PPG for true blood oxygen and metabolic trends, skin-conductance sensors that sense stress before you feel it, and bioelectrical impedance for body composition. Our most complete device (Max 7, built on the S101 platform) is the most complete expression of that portfolio — it gathers every technology we've built into one device — but the science on these pages belongs to the Fitaos platform as a whole, not to any single product.
Our Vision
We believe health insight should not be a privilege of the few. Fitaos exists to put reliable health awareness into an everyday device — not to replace your doctor, but to give you a continuous, personal baseline you can actually act on. When you know your numbers, you can change your habits. When you understand your body's signals, you stop guessing. That is the future we are building: prevention that is personal, quiet, and always with you.
These pages are our open notebook. For consumers and for the market, we explain — in plain language — how each technology works, where it applies in daily life, and why it matters, so you can trust what you're wearing. Just as important, we are straight about the limits: Fitaos devices are wellness companions, not medical instruments. Some metrics are trends and estimates rather than diagnoses, and no reading here should take the place of professional care. Knowing both the power and the boundary is exactly what real trust is built on — and that honesty is the whole point of this site.

The Science, Side by Side
How the Leaders Sense Health — and Where Fitaos Stands
Every major wearable uses a different mix of sensors. Understanding the leader's approach helps you see exactly what Fitaos does differently — and why.
Below is an honest map of the five core health-sensing systems across the four brands consumers compare us with. The pattern is clear: true electrodermal activity (EDA) and oscillometric air-pump blood pressure are the two rarest, most clinically meaningful technologies — and Fitaos builds both into its flagship.
| Sensing system | Apple Watch | Garmin | Samsung Galaxy | Huawei | Fitaos |
|---|---|---|---|---|---|
| Blood pressure | Not offered | Not offered | PPG estimate — needs cuff calibration every 28 days | ✅ Air-pump (oscillometric), Watch D | ✅ Air-pump (oscillometric), precision pump |
| ECG (single-lead) | ✅ FDA-cleared AFib | Not on wrist | ✅ | ✅ (select models) | ✅ Precision single-lead ECG |
| Blood oxygen (SpO2) | ✅ | ✅ | ✅ | ✅ | ✅ 4PD true SpO2 |
| HRV / recovery | ✅ HRV + Mindfulness | ✅ Body Battery (HRV + sleep + activity) | ✅ HRV-based stress | ✅ | ✅ SDNN / RMSSD / LF-HF + fatigue |
| EDA / stress | HRV only | HRV only | HRV only | HRV only | ✅ True EDA (like Fitbit Sense) |
| Body composition (BIA) | Not offered | Not offered | ✅ Watch 4+ | Not on watch | ✅ BIA body fat / BMI |
Comparison reflects generally available consumer features of each brand's flagship lines. Apple Watch ECG is FDA-cleared for atrial fibrillation in select regions; Samsung's wrist BP uses PPG estimation and is not a substitute for a cuff. Fitaos features are wellness tools, not medical devices.
The Companion App
Meet GBAND — Where Your Data Becomes Insight
A sensor is only as useful as what you can do with its readings. GBAND is the Fitaos companion app — the upgraded version of HBAND — that turns raw signals from your wrist into clear, shareable, and family-connected insight.
The value chain is simple: your watch measures → GBAND presents and analyzes → you understand and act. That last step is where most wearables stop short. GBAND closes it.
👨👩👧 Family Account
Share health data and watch over loved ones remotely — the killer feature for "buying one for my parents": see their heart rate and blood-pressure trends from anywhere.
🤖 AI Analysis
Up to 5 free AI analyses per day across heart rate, HRV, blood pressure, SpO2 and sleep — turning numbers into plain-language conclusions you can actually use.
📊 Trend Sharing
Generate clean trend charts for heart rate, HRV, blood pressure, SpO2 and sleep — one tap to share with your doctor at the next visit.
🎯 Calibration & Goals
Enter a reference blood-pressure value to make your trend more accurate, and set sleep and step goals to track real improvement over time.
🔗 Data Ecosystem
Your metrics sync with WeRun, Health Connect, Strava and Apple Health, so Fitaos fits the apps you already live in.
🌙 Whole-Day Picture
Every sensing system on this page feeds one timeline in GBAND — heart, blood, stress, sleep and body composition in a single view.
Important — wellness companionGBAND provides general wellness information and trend awareness. It is not a medical device and does not diagnose, treat, cure or prevent any disease. Share its reports with your physician as context, not as a replacement for professional care.
