Kilo - Weight & BMI Tracker

Kilo is a simple, beautiful, and privacy-first weight tracker designed to help you reach your health goals — whether you're losing weight, gaining muscle, or just staying on track.

Log your weight daily, visualize your progress with clean charts, and get insights that actually matter. No accounts, no cloud syncs, no complicated setup. Just open the app, log your weight, and watch your journey unfold.

TRACK YOUR WEIGHT, YOUR WAY

Log entries in kilograms or pounds with just a few taps. Add notes to remember the context — "after breakfast," "post-workout," "cheat day" — and attach progress photos directly from your camera or gallery. A built-in calendar lets you see your entire history at a glance, with highlighted dates so you never miss a day.

SMART PROGRESS DASHBOARD

See the big picture with an interactive weight chart filtered by week, month, or all time. Track your minimum, maximum, and average weight. Monitor weekly and monthly changes, view your current and best streaks, and get a projected date for reaching your goal. A circular progress ring on your home screen shows exactly how far you've come.

BMI & BODY FAT ANALYSIS

Your BMI is calculated automatically and displayed on a color-coded semicircular gauge — from underweight to obese — so you always know where you stand. Go deeper with the built-in Body Fat Calculator, which uses the U.S. Navy method to estimate your body fat percentage based on simple body measurements. Results are saved and shown on your progress dashboard.

BEFORE & AFTER PHOTO COMPARISON

Put your transformation side by side. Pick any two entries with photos and compare them with the time elapsed and weight difference displayed clearly. Nothing motivates like seeing real visual progress.

PRIVACY & SECURITY

Your data stays on your device — always. Protect the app with a 4-digit PIN and optional biometric authentication (Face ID or fingerprint). No account required, no data uploaded, no tracking. Your body, your data, your business.

DAILY REMINDERS

Set a daily reminder at your preferred time so logging your weight becomes a habit. Consistency is key, and Kilo helps you stay accountable.

PERSONALIZED EXPERIENCE

Choose between dark mode, light mode, or let the app follow your system setting. Set your height, goal weight, and preferred unit — Kilo adapts to you.

Kilo is fully localized in English, Spanish, French, German, Italian, and Portuguese.
