About

Weight Diary · BMI Calculator

Features
Read full description

Calculate BMI from height and weight in metric or imperial units. View a labeled gauge and adult reference categories, copy or share the result, and save today’s weight without retyping. Keep a dated weight history, edit or delete readings, and explore a chart with individual readings and a clearly labeled logged-day average trend estimate when enough data is available. Choose an optional lose, gain or maintain direction, or just track. Set your own reference or range. Weekly consistency recognizes check-ins, not lower weight. Choose your cadence, pause or hide encouragement. Daily reminders are optional and separate from weekly consistency. All features are free, with ads and no subscription or account required. Weight records stay on this device; calculation and logging work offline. Ads may use internet. No account-based cloud synchronization. BMI is an adult screening measure, not a diagnosis or direct body-fat measurement. It does not distinguish muscle from fat and is not intended for children or pregnancy. The app does not prescribe a target weight, diet or rate of change. Ask a healthcare professional for personal advice.
