How Verve reads your day beyond workout minutes

Sedentary Hours
Verve divides your day into one-hour slots from7am to 10pm. For each slot it reads your step count from Apple Health.
The 50-step threshold is intentionally low — even a short walk to the kitchen clears the hour. Apple Watch batches step data and syncs periodically, so today's count may dip and recover as earlier hours are updated.
Why hourly, not per-minute?Per-minute queries require HealthKit to process months of raw pedometer data at once — on most devices that query hangs indefinitely. Hourly data is pre-aggregated by iOS and returns instantly.
Standing Minutes · Apple Watch only
Apple Watch continuously monitors posture using its accelerometer and gyroscope. Verve reads Apple Stand Time — the raw cumulative minutes the Watch classified you as upright and moving.
This is not the green Stand ring. The ring counts hours where you stood for ≥1 minute (max 12/day). Standing Minutes counts the actual total — so 46 minutes across the day appears as 46, even if no single hour crossed the ring threshold.
Research shows total sedentary time and standing time are independent predictors of health outcomes — even for people who exercise regularly. Verve tracks both so you get the full picture beyond just workout minutes.
Biswas et al, Annals of Internal Medicine 2015
Meta-analysis of 47 studies, 240,818 person-years. Prolonged sedentary time is independently associated with all-cause mortality, cardiovascular disease, type 2 diabetes, and cancer — regardless of moderate-to-vigorous physical activity level. Participants in the highest quartile of sedentary time (≈10.6 h/day) had significantly elevated risk. Basis of Verve's first sedentary bar threshold at 10.6 h.

Ekelund et al, The Lancet 2016
Pooled analysis of 16 studies, 1,005,791 individuals. Sitting ≥8 h/day was associated with increased all-cause mortality unless offset by 60–75 min/day of moderate physical activity — a threshold most adults do not reach. Risk was highest above 12 h/day of total sedentary time, regardless of activity. Basis of Verve's second sedentary bar threshold at 12 h.

Patterson et al, BMJ 2018
Systematic review and meta-analysis of 13 prospective studies, 1,020,840 person-years. High sedentary time is associated with a 24% greater all-cause mortality risk, 14% greater CVD mortality risk, and 17% greater cancer risk, independent of physical activity. Risk increases steeply above 10 h/day.

Diaz et al, Annals of Internal Medicine 2017
7,985 adults followed for 4 years. Total sedentary time AND uninterrupted sitting bouts both independently predict mortality. Frequent breaks from sitting are protective even for those with the same total sedentary hours — supporting the importance of how sitting is distributed, not just how much.

Diaz et al — Patterns of sedentary behavior and mortality, Annals of Internal Medicine 2017
7,985 adults aged 45 and over from the REGARDS cohort, wearing hip accelerometers, followed for a median of 4 years. Mortality was associated with the MEAN LENGTH of uninterrupted sedentary stretches independently of total sedentary time: people accumulating their sitting in bouts of 30 minutes or more carried the highest risk. Total volume and the pattern of accumulation are separate exposures — the same 8 hours broken every half hour is not the same 8 hours taken in blocks. 30 minutes is the mark Verve draws on the meter.

Dempsey et al — Interrupting prolonged sitting, Diabetes Care 2016
A randomised crossover trial in adults with type 2 diabetes. Breaking up prolonged sitting with brief, frequent activity — short bouts of light walking or simple resistance activities every 30 minutes — lowered postprandial glucose and insulin compared with sitting continuously. The consistent finding across this literature is the FREQUENCY of breaking, not the intensity of the break: a single hard session later does not substitute for standing up.

What each figure on the card means
Sedentary hours. A waking hour with fewer than 50 steps in it counts as sedentary. Steps come from Apple Health, so nothing is typed in. Waking hours are your measured sleep where Verve has it, and 7am to 10pm where it does not — the card says which, because an assumed wake time counts somebody's actual lie-in as sitting.
Unbroken sitting. The longest run of consecutive sedentary hours, not the daily total. This is the figure the evidence is actually about: risk tracks uninterrupted sitting rather than hours accumulated across a day, and six hours broken every thirty minutes is a different day from six hours in one block. A sleep hour or a workout ends a run — you were not sitting through either.
Standing minutes. Minutes Apple Watch detected you upright and moving. More precise than the Stand ring, which credits a whole hour for one minute on your feet: this counts the minutes themselves. Apple Watch only.
Napped. Daytime sleep, shown when there was some. A nap is any sleep session that does not begin in the night (20:00 to 05:00), however long it runs. It is drawn as rest on the terrain and excluded from sitting — you were not sitting through it — and it is excluded from last night's sleep on the Sleep card, because a nap is not a bedtime. The same rule decides both.
The 24-hour terrain. Height is steps per hour. The strip beneath it is the hour's state: green active, orange sedentary, blue asleep (naps included), grey an hour that has not happened yet.
Longest sit, and sits over 30 minutes.Uninterrupted sitting, detected from five-minute step buckets rather than hours — the resolution the evidence needs. Diaz found that mortality tracked not only total sedentary time but how it accumulated: the excess sat with bouts of thirty minutes or more, and was highest in people whose sitting came in blocks of an hour or longer. A bout is closed by any movement, by a recorded workout (a swim registers no steps and would otherwise read as the day’s longest sit), and by sleep, naps included. Under the terrain a thin row marks each one — amber to an hour, red past it — so the figure above can be read off the day rather than trusted. Verve had this once on hourly steps and removed it, because an hourly total cannot see a thirty-minute bout; it returned only when the data could support it, and on a day without fine buckets it shows nothing rather than zero.
