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
Advanced sensors capture 50+ biomarkers continuously — HRV, resting heart rate, SpO₂, respiratory rate, temperature and sleep — with no gaps and no manual logging.
The App learns your baseline
Agen's AI builds your personal baseline, surfaces the deviations that matter, and translates raw signals 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.
Driven by data, not guesswork
What Agen Band measures
Six dimensions of health, captured continuously. We're honest about each signal — high precision where it's strongest, directional where it's a trend.

Good quality for the money. The sleep tracking lines up well with how I actually feel. Delivery was quick and the packaging is lovely.
S
So glad I made the switch to Agen. Step and activity tracking feels accurate to me. Would happily recommend it to friends. A few weeks in and it's become part of my daily habit.
N
Quietly excellent. Charging is fast and the magnetic connector is foolproof. Customer service was genuinely helpful when I asked about pairing.
B
Does everything I wanted it to. Lightweight and sits well even overnight. A few weeks in and it's become part of my daily habit.
This made our day, thank you for the kind words and for being part of the Agen community.
M
Five stars from me. Comfortable enough that I forget I'm wearing it.
