Train harder, recover smarter. Know exactly when your body is ready to push — and when to hold back.
Honest metrics · No subscription
Your life, decoded
See what's really happening inside your body. The Band tracks five dimensions of health from your wrist and syncs them to the Agen app — where they join your face scans, lab results and 60+ connected apps to become one clear daily protocol. Every number is labelled by how it's produced, and there's not a single subscription.

Free app — no add-ons
A system, not a gadget
Measure. Analyze. Act.
Most wearables stop at data. Agen closes the loop — your Band measures, the app analyzes, and your protocol acts on what it finds.
The Band reads your body
The Band’s sensors track five dimensions of health from your wrist around the clock — heart rate, SpO₂, sleep, stress and steps — with no manual logging, then sync to the Agen app.
The App learns your baseline
In the app your Band data joins your face scans, uploaded lab results and 60+ connected apps and devices. Agen’s AI builds your personal baseline, surfaces the deviations that matter and translates them into plain-language guidance. No subscription required.
Your protocol adapts
Recovery dips, stress climbs — Agen recommends the supplements and habits that fit, dosed by the Robot. The result you feel feeds back into the loop.

What the Band tracks
Five dimensions of health, read from your wrist around the clock. Every signal is labelled by how the number is produced — read by the sensor, calculated from it, modelled as an estimate, or next up on the roadmap.

Agen Band is a wellness device, not a medical device. It does not diagnose, treat, cure or prevent any condition — and it does not measure blood pressure. Signals marked “next up” are planned software features and not yet available.
In the app
What the Agen app adds
The Band is one input. In the free Agen app it joins your face scans, uploaded lab results and 60+ connected apps and devices — together they build your Agen profile. Blood pressure is one of them, and it comes from the face scan or a connected cuff, never from the Band.
The Agen app works on its own with just a face scan. The Band is what makes the tracking continuous and hands-free.
-
30-second face scan
Point your phone camera at your face for heart rate, HRV, breathing, stress, cardiac workload and an at-a-glance blood pressure estimate. No wearable needed — and all of it modelled, so read it as a trend.
-
Lab results you upload
Blood panels and at-home tests bring real, assayed biomarkers into your profile — the kind no wrist sensor can see.
-
60+ connected apps & devices
Apple Health, Garmin, Oura, Whoop, Strava, Withings, Omron and more — including a validated blood-pressure cuff, if you use one.
-
AI that ties it together
Your baseline, the deviations that matter, and one clear daily protocol. Included free — no membership, ever.

How Agen Band compares
The difference isn't a feature — it's a business model. Most wearables lock your data behind a recurring fee.

Explore the RobotQuestions, answered
The Band is a wrist sensor. It tracks five dimensions of health, continuously: heart rate, blood oxygen (SpO₂), time asleep, stress load, steps and active energy. More signals — resting heart rate, HRV, overnight heart rate and HRV, sleep stages and movement — are next up, and they switch on through the Agen app.
The Agen app is where the bigger picture lives. Your Band data is one input; the others are the 30-second camera face scan (which is where a blood-pressure estimate comes from), blood panels and at-home tests you upload, and 60+ connected apps and devices — including a real blood-pressure cuff if you own one. The app builds your baseline from all of it and writes one daily protocol.
Short version: the Band tracks your body around the clock; the app combines that with everything else and tells you what to do about it. The Band itself does not measure blood pressure — it has no sensor for it.
Correct — there's no membership fee, ever. Many popular wearables are subscription-only, or charge a monthly fee to unlock their full insights. Agen Band is a one-time purchase: you own the hardware and your data, with every AI insight included.
It depends on the signal — so we label every one of them on this page. Measured: heart rate, steps and movement are read directly by the Band’s sensors — an HX3697 optical heart-rate sensor and a 6-axis motion sensor. Derived: resting heart rate, HRV, blood oxygen (SpO₂) and time asleep are calculated from that sensor signal using established methods. Estimated: sleep stages, stress load and active energy are model estimates — useful as trends across days and weeks, not as single readings, and not equivalent to a sleep study or a clinical oximeter.
The Band does not measure blood pressure — it carries no sensor for it. The blood-pressure figure you may see in the Agen app comes from the 30-second camera face scan, or from a blood-pressure cuff you connect — never from the Band. The face-scan figure is a model estimate for general wellness and is not a substitute for a validated cuff.
Agen Band is a wellness device. It has not been through medical-device validation and is not intended to diagnose, treat or monitor any condition. If a number matters medically, confirm it with a clinician and a validated device.
Your data is yours. It syncs securely to the Agen App and is used to generate your personal insights. We don't sell your data, and there's no subscription gate standing between you and your own numbers.
Yes. The Band and Agen App work fully on their own — track your metrics and get AI guidance. Adding the Robot and supplements simply closes the loop, turning insights into an automated daily protocol.
Agen Band works with iOS 9+ and Android 5.1+ over Bluetooth LE 5.4, and syncs with Apple Health. Inside it runs a Nordic nRF54L15 chipset with an HX3697 optical heart-rate sensor; the 110 mAh battery lasts 7–10 days on a single charge over the included magnetic cable.

Agen Band is a wellness device, not a medical device. It is not intended to diagnose, treat, cure or prevent any disease or medical condition. The Band does not measure blood pressure — the blood-pressure figure in the Agen app comes from the in-app face scan or a connected cuff. Sleep stages, stress load and active energy are model estimates for general wellness use, not clinical measurements, and do not replace professional medical advice or a validated medical device.
