Body Vitals: Health Widgets
4.1.7 | iOS 26.0+
GETTING STARTED
Open the app and grant HealthKit permissions when prompted. Body Vitals reads Apple Health data and does not require account creation. If other apps write into HealthKit, those signals can appear in Body Vitals automatically.
Body Vitals supports iPhone on iOS 26.0 or later, including iPhone Duo. It is not offered as an iPad app on the App Store. Apple Watch is recommended for richer signals (HRV, sleep stages, SpO2), but any source that writes to Apple Health can contribute data. Apple Watch Series 12 and Ultra 4 are supported: they record heart rate every five seconds and HRV as often as every five minutes, and Body Vitals reads that density without slowing down. On iOS 27, if you set heart rate zones in Apple Health, Body Vitals uses those instead of estimating its own.
Yes. On the unfolded inner display, compact dashboard cards sit side by side in two columns, while heatmaps, metric grids and cinematic views like Recovery Planet and Vitals Core keep their full width. On the cover display, onboarding and the Today header are laid out around Duo's Dynamic Island, and the Recovery Battery Live Activity shows your full Daily Capacity % on the island. Your scores and data are exactly the same on every display.
Yes. Body Vitals includes Apple Watch complications and a dedicated watch app (Pro). Complications can show readiness or other metrics at a glance (including Live Heart Rate as a selectable complication metric), and the watch app lets you customize which metrics appear on your watch dashboard (including an optional live heart rate tile while the watch app is open).
Long-press your home screen, tap the "+" button, search for "Body Vitals", and add widgets. Free includes small/medium home screen widgets and lock screen widgets. Pro unlocks large widgets and the StandBy Readiness Dial.
Just ask - no setup needed beyond opening the app once so iOS can register the shortcuts. Answers come from your last sync, so Siri responds without launching the app. The same actions are available in the Shortcuts app, on the Action Button, and as a Control Center button. Say the whole sentence, including "Body Vitals":
If Siri answers from the web instead of the app, say the full sentence rather than a shortened version - Siri matches these phrases closely, so dropping words can send the request to web search instead of Body Vitals.
Body Vitals only shows data that exists in Apple Health. If a metric shows "--", it means that data type has not been recorded yet. Common fixes: ensure HealthKit permissions are granted for all categories, wear your Apple Watch overnight for sleep/HRV, and make sure third-party apps are writing to Apple Health.
READINESS & SCORES
A 0-100 score computed from HRV, sleep duration, resting heart rate, SpO2, and training load. It uses adaptive calibration - the algorithm learns your personal baselines over 90 days. Recovery HRV is read over a fixed overnight window, and compared against a baseline averaged from your last seven nights, so a score you check in the morning and one you check in the evening measure the same thing. Higher means your body is more recovered and ready for intense activity.
Pro includes six composite scores: Longevity, Cardiovascular, Metabolic, Circadian, Mobility, and Allostatic Load. They are surfaced in the Health Command Center large widget and companion app views. Allostatic Load (0-100, higher = more physiological burden) measures cumulative multi-system stress from HRV, sleep debt, training form, blood pressure, blood glucose, and wrist temperature. Each score has a detail view with research citations.
Pro feature in the Activity tab. It automatically identifies Zone 2 workouts from the raw heart rate data recorded during workouts in Apple Health - no manual zone entry needed. It uses the scientific definition (65-75% of estimated true max HR per San Millan and Brooks 2018) and cross-references your VO2 Max for accuracy. Works with any app or device writing heart rate data to HealthKit.
Pro feature visible inside the Training Load detail view. It compares your 7-day rolling training load to your 28-day rolling load. A ratio above 1.5 indicates High Risk (associated with 2-4x higher injury risk in research by Gabbett 2016, BJSM). The optimal range is 0.8-1.3. It helps you identify when training is ramping too fast relative to your adaptation capacity.
Pro feature accessed via the Longevity composite score. It calculates a weekly 0-100 score across five longevity pillars: Zone 2 cardio (150+ min/week), strength training (2-3x/week), sleep quality, stress and HRV management, and metabolic health. Each pillar shows your actual data and a progress bar so you can see where to focus. Resets weekly.
Pro feature that reads menstrual flow data from Apple Health and identifies your current cycle phase (Menstrual, Follicular, Ovulatory, Luteal) based on your own history - not a generic 28-day estimate. The main place to find it is the dedicated Cycle Phase card in the Recovery tab, and a secondary badge appears inside HRV detail when cycle context explains a lower HRV reading as expected variation rather than an anomaly. If Apple Health has menstrual flow data but there are not enough recent entries to estimate the current phase confidently, Body Vitals still shows the feature with a fallback state instead of hiding it. Cycles up to 90 days are measured rather than discarded, and when your cycle length varies too much for a phase estimate to be trusted - the pattern typical of perimenopause - Body Vitals says so instead of predicting a date. On iOS 27 a menopausal state logged in Apple Health is recognised too. This feature only activates when cycle data exists in HealthKit; it never relies on your reported biological sex.
Pro feature in the Health tab. It is a conversational AI coach running entirely on your iPhone using Apple Foundation Models (iOS 26) - no data is sent to any cloud service. You can ask plain-language questions ("should I train today?", "why is my HRV low?") and get answers grounded in your current Apple Health data. Chat history is stored locally on your device and can be cleared at any time.
Pro feature that shows the medications you track in Apple Health as a living record: adherence, a 30-day taken / skipped / missed dose ribbon, your actual dose times, streaks, and miss patterns. Alongside each one, its measured association with your next-morning HRV, resting heart rate, and readiness - reported only when the sample size and effect size clear an evidence gate, with honest "no clear effect" verdicts. Logging stays in the Apple Health app: Body Vitals reads your medication data and never writes it. These are observed associations in your own data, not medical advice - never change how you take a medication based on this screen. For optional over-the-counter supplements only, a one-tap Experiment Lab trial fills in from the doses you log - it is never offered for prescription medication.
Pro feature for running a structured 2-4 week n-of-1 experiment on yourself. Pick a habit - magnesium before bed, an earlier dinner, a daily walk - and mark the days you did it by hand, follow a balanced plan that shuffles habit and off days so weekdays and weekends even out, or let days fill in automatically from Echo tags and data already in Apple Health (doses, evening walks, alcohol, breathing sessions). Days with no data are left out, never counted as off days, and your own mark always wins. Evidence builds from Early to Building to Consistent as days accumulate, with an effect size and warnings when something else - like weekends or training load - could explain the result. You can extend a finished experiment by 7 days or run it again, and mark a day from Siri, Shortcuts or Control Center. Results are associations observed in your own data, not proof and not medical advice. From Med Bay, experiments are offered only for optional over-the-counter supplements, never for prescription medication - never stop or change a prescribed medication without talking to your doctor.
Pro feature for logging lifestyle tags - sauna, late caffeine, alcohol, a hard workout and 30+ more - and the next morning see how it echoed in your HRV, resting heart rate, sleep and readiness, next to what research generally finds. Tag today or any of the last 6 days, add tags Apple Health suggests with a tap, and after a few weeks Your patterns shows how your mornings tend to differ after each tag. Observed in your own data, not proof; computed entirely on-device.
Turn on Fill in automatically when you start an experiment, and Body Vitals marks each day from data you already have: your Echo tags, doses you log in Apple Health (for supplements started from Med Bay), walk workouts starting at 5 p.m. or later, alcohol logged in Apple Health, and Body Vitals breathing sessions. A day with no data stays unknown and is left out of the comparison - it is never counted as an off day. Tap any day to set it yourself; your own mark always wins. Activity before 4 a.m. counts for the evening before. Everything is read on-device; Apple Health is never written to.
An optional schedule that decides your habit days in advance: every two days get one habit day and one off day, in shuffled order. That keeps weekdays, weekends and busy days evenly spread between the two groups, which makes the comparison fairer than picking days yourself. The plan shows on upcoming days, the app tells you how closely you followed it, and extending an experiment keeps the days already planned.
Each habit or off day is paired with the next morning's HRV, resting heart rate and readiness, and that night's sleep. Evidence grows as both groups fill up: Early with 4 or more days in each group, Building with 7 or more, and Consistent with 10 or more per group plus at least a medium effect and no warning signs. Only the outcome you chose as primary gives the verdict; the other three are shown as exploratory. Warnings appear when weekends, training load, or values that already differed the day before could explain the result, and a 14-day before-you-started average is shown for context. A finished experiment can be extended 7 days at a time, up to 42 days. Results are associations observed in your own data, not proof and not medical advice.
Yes, with Pro. Say "Hey Siri, mark my experiment day in Body Vitals", add the Mark Experiment Day button to Control Center (you choose which experiment when you add it), or add the small Experiment widget, which shows day X of Y and today's plan. None of them show the habit's name, and marking a day needs an unlocked iPhone. You can also turn on a private daily reminder with Done and Not today buttons; it never names the habit either.
Open Control Center, tap +, add a control, then search for Body Vitals. Check Readiness opens your readiness breakdown in one tap. Mark Experiment Day (Pro) marks today as a habit day in a running experiment - you choose which experiment when you add it, and it never shows the habit's name. Both need an unlocked iPhone to act. In the app, Settings -> Widget Guide shows the same steps, and Settings -> Siri Notes lists every Siri phrase.
Echo suggests tags from data already in Apple Health, and nothing is added until you tap it: alcohol logged, a strength workout, a workout of 90 minutes or more, a workout ending after 8 p.m., a high-strain day, a rest day, mindful minutes, 30 or more minutes in daylight, caffeine logged after 2 p.m., and naps of 15 minutes or more starting between 10:00 and 19:00. You can tag today or any of the last 6 days. Once a tag has 5 or more days with it and 5 or more logged days without it, Your patterns shows how your next morning tends to differ. These are associations observed in your own data, not proof. An optional evening reminder arrives at a time you choose, skips days you have already tagged, and never names a tag.
Med Bay only offers Experiment Lab trials for a closed list of optional over-the-counter supplements: magnesium, valerian, tart cherry, glycine, theanine, ashwagandha, rhodiola, omega-3 and fish oil, beetroot, vitamin B12 and taurine. An experiment needs off days, and skipping a prescribed medicine to test it could be harmful, so prescription medicines never get a trial - nor does melatonin, which is prescription-only in the UK, the EU, Australia and Japan. Never stop or change a prescribed medication without talking to your doctor.
Five horizontal bars (HRV, Sleep, RHR, SpO2, Load) showing your readiness sub-scores. Each bar is color-coded (green, amber, red). Pro shows composite health scores on the dashboard without blur; free users see blurred previews with Upgrade to Pro where those sections appear.
Interactive behavior varies by widget type. Examples include telemetry toggles, Sleep Architecture stage/trend toggles, StandBy Readiness Dial insight/workout switching (Pro), and Weekly Pattern large widget cell selection (Pro). The in-app Weekly Pattern heatmap on the dashboard is included in Free.
Pro feature. Body Vitals has two AI coaching modes. AI Daily Coaching generates structured daily insights (Readiness, Sleep, Activity, Body & Heart) shown as cards on the Health tab and as chips on the Health Command Center widget - refreshable on demand. Neural - AI Health Coach is a conversational interface where you can ask open-ended questions and get answers grounded in your live HealthKit data. Both use Apple Foundation Models running on-device. No health data is sent to any third-party AI service.
No. Body Vitals does not send your health data to any third-party AI service. AI Coaching uses Apple Intelligence (Apple Foundation Models), Apple's native framework. It runs on your device.

DATA & PRIVACY
Body Vitals does not require an account and keeps core health processing on your device. Health data comes from Apple Health; what the app stores for widgets stays on your iPhone. Read our full Privacy Policy.
Delete the app to remove Body Vitals local app storage. Health data remains managed in Apple Health. Body Vitals only reads HealthKit data and never writes to Apple Health.
TROUBLESHOOTING
iOS controls widget refresh frequency. You can force a refresh from Settings inside the app. Also ensure the app has background refresh enabled in iOS Settings > General > Background App Refresh.
The readiness engine needs HRV and sleep data as minimum inputs. If you don't have an Apple Watch or a device that provides these, some signals will score 0. The engine also needs 7-14 days of data to establish your personal baseline for accurate calibration.
AI Coaching needs a compatible iPhone and iOS 26 or later. If your device does not support it, that part of Pro will not be available.
