“Know thyself.” The oldest advice. The hardest to follow. Until now.
Weight, blood pressure, glucose, VO2 max, SpO2. BLE heart rate monitors. Progress photos. Body measurements. Everything about your biology, unified in one place and connected to everything you do.

Evidence
Everything in Métron is built on peer-reviewed evidence. Here's what the research says about tracking what matters.
“Self-monitoring of blood pressure reduces systolic BP by 3.2 mmHg.”
A meta-analysis of 25 trials (n = 10,487) found consistent improvements when patients actively tracked their own blood pressure readings over time.
, Tucker et al., JAMA 2017
“VO2 max is the single strongest predictor of all-cause mortality.”
Among 122,007 patients, cardiorespiratory fitness was inversely associated with all-cause mortality with no observed upper limit of benefit.
, Mandsager et al., JAMA Netw Open 2018
“Body composition changes can be masked by scale weight for months.”
Simultaneous fat loss and muscle gain can produce stable or increasing scale weight while dramatically improving body composition and metabolic health.
, Heymsfield et al., Am J Clin Nutr 2014
The Problem
Apple Health collects 400+ data types.
It doesn't tell you anything about them.
It doesn't surface the fact that blood pressure dropped because a TRT dose is dialed in alongside consistent cardio three times a week. It doesn't show that VO2 max jumped because zone 2 training was added last month.
It doesn't correlate improving sleep scores with the magnesium supplementation started three weeks ago. It doesn't flag that hematocrit is creeping up alongside a rising testosterone dose. It doesn't connect the dots between a shrinking waist measurement and increasing deadlift volume.
It collects.
SomaForge interprets.
Capabilities
Métron consolidates every biomarker, measurement, and health signal into a unified dashboard that actually makes sense of what your body is telling you.
Weight, blood pressure, glucose, VO2 max, SpO2. Log manually or sync automatically from HealthKit. Trend charts that show where you were, where you are, and where you're heading.
Pair any Bluetooth Low Energy chest strap or arm band. Real-time heart rate during workouts, resting heart rate trending, and heart rate recovery tracking.
Front, side, back. Date-stamped with your current weight and measurements overlaid. Side-by-side comparison so you can see what the scale can't tell you.
Chest, waist, hips, arms, thighs, calves. Track circumference changes over time. See which areas are growing, shrinking, or holding steady.
Sleep stages, HRV, resting heart rate, steps, VO2 max, SpO2, weight, blood pressure. Bidirectional sync that pulls in everything Apple Health has on you.
Connected Intelligence
Métron doesn't just record numbers. It connects them to everything else you track in SomaForge, surfacing relationships that no single-purpose app could ever find.
Phármakon + Métron
Phármakon tracked the TRT protocol timeline. Métron tracked blood pressure, weight, and resting heart rate trends alongside it. When something shifted, Noûs had the full medication timeline for context.
Soma + Métron
Soma tracks your training volume and progressive overload. Métron tracks body composition, measurements, and progress photos. See the direct relationship between the work you put in and the results you get out.
Trophē + Métron
Trophē tracked micronutrient intake—vitamin D, iron, B12, magnesium. Métron showed vitals and weight trends over the same period. Intake patterns connected to measurable outcomes.
When your data lives in silos, you get fragments. When it lives in one system, you get understanding. That's the difference between collecting and forging.
By the Numbers
Not another dashboard that looks pretty and tells you nothing. Real depth, real context, real ownership.
