Health & Fitness

Thirteen calculators and trackers for body measurements, nutrition and daily routine. The body-composition group covers BMI, BMR, TDEE, macronutrient targets, a calorie calculator and a calorie-deficit planner, which together let you go from height and weight to a daily calorie and protein target. The cycle group covers ovulation and pregnancy dates. The routine group covers water intake, a sleep calculator that works backwards from your wake time through 90-minute cycles, a habit tracker and a guided breathing exercise that paces inhale and exhale on screen. There is also a bra size calculator that converts measurements between sizing systems. Every calculation runs in your browser and nothing is stored on a server, which matters here more than elsewhere: these are health figures. None of these tools is medical advice, and none of them replaces a clinician.
