Work out your BMI and the healthy weight range for your height in pounds, your ideal body weight by the Devine, Robinson, Hamwi and Lorentz formulas, the adjusted range if you are 65 or older, a child or teen BMI percentile, your fat versus lean mass split, your waist-to-hip ratio and waist risk, and your body surface area.

Put your reading against the published reference range: blood pressure by ACC/AHA and by WHO, the full lipid panel, HbA1c with estimated average glucose, fasting glucose, ferritin, oxygen saturation adjusted for altitude, testosterone by age, FSH around menopause and semen analysis against WHO 2021 limits.

Get your maximum heart rate by both the Fox and Tanaka formulas, your five training zones in beats per minute, the percentage of 1RM behind an RPE or reps-in-reserve target, a step goal based on the actual evidence, calories by yoga style, and how much fluid and sodium to replace.

Work out your BMR by Mifflin-St Jeor or Harris-Benedict, your TDEE at your real activity level, and the calorie target and protein, fat and carb grams for cutting, maintaining, lean bulking or recomping — plus 16:8 fasting meal splits, Atkins carb allowances, DASH macros and sodium, glycemic load, daily fibre and what a drink costs you.

Estimate annual health-plan cost from premiums, deductible, coinsurance, copays and out-of-pocket maximum, then compare two plans.

Find your fertile window and ovulation day for regular or irregular cycles, then get the due date from your last period, a known conception date, an IVF transfer or an ultrasound CRL, plus how many weeks you are, the fetal weight percentile and the weight gain range for your BMI.
