BMI Tracker is a free browser-based BMI calculator and simple history log. Calculate BMI in US or metric units, read a clear adult category, save entries locally, and export CSV when you want a backup. No account, no email, and your measurements stay on your device.

Hi Product Hunt 👋 We’re launching BMI Tracker today - a small, free tool for calculating BMI and tracking BMI changes over time privately in your browser. We built it because many BMI calculators feel cluttered, ask for unnecessary details, or show a number without enough context. Our goal is much simpler: help people get a quick BMI result, understand the category in plain language, and optionally keep a private history if they want to watch the trend over time. What it does: • Calculate BMI using metric or US units • Show the adult BMI category clearly • Save BMI entries locally in your own browser • Add notes to entries • Export your history as CSV • Work without signup, email, or account creation A clear note: BMI Tracker is not a medical app and does not diagnose anything. BMI is only a screening measure, so we keep the interpretation conservative and encourage people to speak with a healthcare provider for personal health questions. We’re not trying to compete with big health platforms or promise anything huge. We made this as a simple community resource. I’d really appreciate your feedback: • Is the calculator easy to understand? • Is the tracking UX clear enough? • What would you add next - better charts, reminders, printable reports, waist-to-height ratio, dark mode, multilingual pages, or something else? Thanks for taking a look. Your feature and UX suggestions would be very helpful.
