Biomize describes patterns in data you and your devices record. Every reference range, threshold and population band it puts on screen comes from the published guidance and peer-reviewed literature listed here, grouped by where you see it in the app.
Biomize is a wellness product, not a medical device. It does not diagnose, treat, cure or prevent any disease, and nothing in it is a substitute for professional medical advice. Reference ranges describe populations — your own targets can legitimately differ, and what is right for you is a conversation with your clinician. If something in your health worries you, or an app reading does not match how you feel, talk to a doctor rather than to this app. In an emergency, call your local emergency number.
Two things are worth reading before any individual number: what consumer wearables can and cannot measure, and the notes on the two composite scores — the Biomize Level and the biological age estimate — which are Biomize’s own descriptive summaries rather than validated clinical measures.
Where you see this: Biomize Levels: every tracked day earns up to 150 XP from ten pillars (Sleep, Recovery, Heart, Activity, Metabolic, Stress, Fuel, Training, Vitals, Skin), scaled by how much of you was measured, multiplied by your streak, plus bonuses for improving, a personal best, logging and a full set of core signals; your level is the highest one your total XP has reached. Levels are a wellness game built on your own tracked data — not a clinical assessment, a diagnosis, or a validated medical index, and no published guideline defines them. What the underlying pillars reward is anchored to the public guidance below.
Where you see this: The estimated biological age, the ± years versus chronological age, and each contributing component: cardiovascular age anchor, VO₂ max bands (female 42/36/30/24, male 50/42/36/30 ml/kg/min), 30-day sleep-score bands (85/78/68), 30-day resting-heart-rate bands (52/60/68 bpm), 30-day mean-glucose bands (100/110/125 mg/dL) and BMI bands (18.5/20/25/30). This is a WELLNESS ESTIMATE built from consumer wearable data. It is not an epigenetic clock, not a validated clinical aging biomarker, and not a diagnosis; the year-weights are Biomize's own descriptive heuristic, chosen so each input moves the estimate in the direction the literature below supports.
Where you see this: The 70–180 mg/dL "in range" band, time-in-range goals, the <70 mg/dL low and >180 mg/dL high guides on glucose charts, the Glucose Management Indicator (GMI), and the fasting reference points (<100 normal, 100–125 elevated, ≥126 mg/dL diabetes range) used to describe your averages.
Where you see this: The 7–9 hour adult sleep-need reference behind sleep targets, the 7-hour floor, and the sleep-regularity and social-jetlag readouts that reward a consistent schedule.
Where you see this: The 150–300 minutes/week moderate-activity reference behind weekly activity goals, and the ~5 active-days/week target the Activity pillar rewards.
Where you see this: The 60–100 bpm typical adult resting-heart-rate reference, and the fitness-leaning bands the Heart pillar and the biological-age estimate use (≈42 bpm scoring highest through ≈90 bpm scoring lowest).
Where you see this: RMSSD values in milliseconds, the population bands used to place your HRV (roughly 15 ms low through 120 ms high), and the night-to-night dip detection. HRV norms vary enormously by age, sex and measurement device, so these bands are deliberately broad and are descriptive only.
Where you see this: VO₂ max in ml/kg/min, the sex-specific bands used on the performance surfaces and in the biological-age estimate (female 42/36/30/24, male 50/42/36/30), and statements that higher cardiorespiratory fitness tracks with healthier aging.
Where you see this: BMI computed from your height and weight on /weight, and the WHO classification used to describe it: underweight below 18.5 (severe thinness below 16, moderate 16–16.9, mild 17–18.4), normal range 18.5–24.9, overweight 25–29.9, and obesity class I 30–34.9, class II 35–39.9, class III 40 and above. The card applies these only from age 20; below that BMI is assessed as BMI-for-age against a reference population of the same age and sex, because BMI itself changes through growth, and the card shows the number without a category. BMI is a population screening measure, not a measure of body composition or individual health: it does not distinguish muscle from fat, is not interpretable in pregnancy, and the BMI at which risk rises differs between populations — the WHO consultation on Asian populations found observed-risk cut-offs ranging from 22 to 25 and identified additional action points (23.0, 27.5, 32.5, 37.5) rather than a single alternative threshold, so this app applies the general WHO cut-offs and states the limitation here.
Where you see this: Readiness/recovery scores, the Recovery pillar, and the guidance that low overnight HRV together with elevated resting heart rate is a reason to take an easier day. Vendor readiness scores (Oura Readiness, WHOOP Recovery) are each vendor's own proprietary composite.
Where you see this: Daytime and overnight "stress" minutes and stress scores derived from heart rate and heart-rate variability. These describe autonomic arousal measured by your device — physical exertion, illness, alcohol, caffeine and heat all raise the same signal. They are not a measure of psychological stress and not a mental-health assessment.
Where you see this: Session-RPE training load, acute:chronic workload ratio (ACWR), aerobic decoupling, pacing and threshold/FTP estimates on the performance and workout surfaces. ACWR in particular is contested — later methodological work disputes the original "sweet spot" framing, so Biomize shows it as a trend in your own history rather than as a risk threshold.
Where you see this: Macronutrient distribution ranges (protein 10–35%, carbohydrate 45–65%, fat 20–35% of energy), protein-per-kilogram guidance, dietary-fibre targets (≈25 g/day for women, ≈38 g/day for men), the added-sugar guidance (<10% of energy) and the calorie and macro estimates produced by photo and barcode logging. Photo-estimated macros are approximations, not measured values.
Where you see this: Overnight SpO₂ averages, the 95–100% typical-range reference, and breathing-disturbance readouts. Wrist and ring pulse oximetry is a wellness measurement, not a medical oximeter, and published work shows pulse oximetry can overestimate true oxygen saturation, with larger errors in people with darker skin. Biomize does not screen for or detect sleep apnoea.
Where you see this: Skin/body-temperature deviation from your own baseline, and "something looks off" style illness flags built from temperature, resting heart rate and HRV together. These describe a departure from your personal baseline. They are not a thermometer reading, not a fever diagnosis, and not an infection test.
Where you see this: Cycle-phase labelling and the typical cycle-length and phase-duration references used to place today in a cycle, plus the luteal-phase temperature and resting-heart-rate shifts Biomize describes. Phase estimates from wearable data are inferred, not confirmed by hormone measurement, and Biomize is not a contraceptive or fertility device.
Where you see this: Reaction-time, memory, attention and processing-speed check-ins and their scores. These are self-administered games used to track change against your own history. They are not neuropsychological tests, are not normed against a clinical population, and cannot detect or rule out any cognitive condition.
Where you see this: Supplement timing suggestions in your daily plan and the interaction/safety flags in the wellness guide. Biomize never suggests starting a supplement, never suggests a dose, and never comments on prescription medicines — it only describes timing for things you already log.
Where you see this: Photo-based skin readouts — region counts, baseline deltas and routine-conflict notes. These describe change in your own photos over time under a quality gate. They are not a dermatological assessment and cannot identify, diagnose or rule out any skin condition, including skin cancer. Anything new, changing or concerning on your skin belongs with a clinician.
Where you see this: Applies to every number in Biomize. Sleep stages, HRV, resting heart rate, SpO₂, temperature, calories and "readiness" from consumer rings, watches and straps are estimates produced by each vendor's proprietary algorithms. They differ between devices, are validated to varying degrees against laboratory reference methods, and are generally better at tracking CHANGE in one person over time than at reporting an exact absolute value. Biomize is a wellness product, is not a medical device, and does not diagnose, treat, cure or prevent any disease.
