The Guide reads each finished week against the one before: training, sleep and blood markers. One win, one next step.
Verve — Cardiorespiratory Fitness & Longevity Tracker
Verve tracks the metric that predicts mortality better than almost any other: your cardiorespiratory fitness (CRF) in METs, validated against 122,000 patients in the Cleveland Clinic study.
What Verve measures
Weekly MET-hours — the primary output of every fitness session
Zone 2 minutes — the aerobic work that moves your CRF
Strength training minutes — independently linked to 23% lower all-cause mortality (UK Biobank, 70,000+)
Daily step count and cadence
CRF performance tier vs your age and sex (Cleveland Clinic / ACSM norms)
Resting heart rate against your own 30-day usual
Heart rate recovery, the minute after each workout ends
Sleep, its stages where your device writes them, efficiency and wakes, bedtime regularity
Physical activity level from your day's energy, with its denominator named
Sitting hours, standing minutes and the day's movement
Metabolic health markers: glucose, HbA1c, blood pressure (from Apple Health's own cuff log), triglycerides, HDL, waist and hip
Heart health markers: ApoB, LDL, Lp(a), hs-CRP
Muscle health: grip strength, chair stand, walk speed, balance, SPPB, body fat %, skeletal muscle %, FFMI
The Guide
Every week, the Guide compares your last completed week with the one before — minutes, Zone 2, strength, sleep, resting heart rate, recovery — and says in two lines what improved and the one thing to do next, with your body markers woven in. The weekly and four-week numbers are free, and so is one written read a week, on any period, months and years included. Pro reads as often as you like.
CRF Testing
Bruce Protocol · 6-Minute Walk · Cooper 12-minute run · 1.5-mile run · Treadmill test · Wearable VO₂Max import · Manual entry from a clinic report. An ACSM screening step first, and a retest reminder every 8 weeks.
Apple Health integration
Reads workouts, heart rate, resting HR, VO₂Max, weight, height, steps, standing time, sleep and blood pressure from any wearable connected to Apple Health. Read only; Verve never writes to Health. Background movement estimated via the Nakanishi (2021) model.
Every threshold and study behind the app is at verve-app.health/science.

Verve 1.6.3 — the Guide, the weekly dose, and honest numbers from any device
THE GUIDE
• The AI Coach is now the Guide. Each week it compares your last completed week with the one before and says in two lines what improved and the one thing to do next. The numbers are free; one written read a week is free on any period; Pro reads as often as you like.
• The Guide can keep a memory of its reads, per account, with your consent; a switch under Settings → Your data → Backup.
TRAINING
• Weekly dose: your week in MET-minutes against the ACC's 500 to 1,000 band, on the Activity tab and in the Monday card; a tap lists the sessions behind the number.
• Zone 2 from a test: a lactate or CPET band from Settings → Profile replaces the estimate.
• Session RPE on strength workouts; two devices recording one run leave one session.
STEPS, MOVEMENT, ENERGY
• A Steps page: today by the hour, this week day by day, your median by week, month and year, against the cited tiers.
• One count a day from any mix of devices: Health's own merge where the phone wrote, a band's daily block counted whole on the day it ends, or the device you choose under Settings → Apple Health → Preferred device. The page says where each count came from.
• Physical activity level: Day, Week, Month and Year, each day on its own denominator; a day's PAL and energy listed for the week. A band that shares workout energy only (WHOOP) gets no PAL, with the reason, and its kilocalories are labelled workout energy.
SLEEP
• Efficiency (asleep over your device's own in-bed window) and wakes, with those over five minutes counted, against the National Sleep Foundation's marks, for any device.
• A night without stages says why, naming the device. The Sleep page reads heart rate and breathing while asleep against your 30 nights.
• Night HRV: Day and the last four weeks, a 7-night mean, one writer per night, named.
BODY
• TG/HDL and ApoB/ApoA1 ratios on the Triglycerides and ApoB cards, with their bands.
• Date of birth in the profile; your age updates itself.
• Blood pressure from Apple Health's cuff log.
ACCOUNT
• Sign-up confirms by a six-digit code on the screen.
• An email the first time your account is opened on a new phone; "Sign out everywhere" in Settings.
• Crash reports, with nothing personal in them, so the next crash is fixed faster.
