BMI Calc + Weight Loss Tracker

No Account. No Cloud. No Subscription.

Your weight and height stay encrypted on your phone. There is nothing to sign up for, nothing syncs anywhere, and the app collects no data about you at all. It works with the plane in airplane mode.

Everything the App Does

Real-Time BMI Gauge

An animated gauge that moves as you adjust your weight, so you can see where a change would put you before you commit to it.

Clear Categories

Underweight, healthy weight, overweight, or obese, with the range boundaries shown rather than just a label.

Charts Over Time

Switch between week, month, year, and everything, so a bad week looks like what it is next to a good year.

Trend Line and Goal Date

A trend line through your entries, with an estimated date for reaching the goal you set at your current pace.

Ideal Weight Formulas

See the established ideal weight formulas for your height, with a male and female toggle.

Streaks and Milestones

Logging streaks for staying consistent, and milestones as you pass them.

Understanding BMI

A plain-language screen explaining what BMI measures, what it does not, and why one number is never the whole picture.

Export and Backup

Export your history as CSV for a spreadsheet or your doctor, and back up or restore everything as JSON.

Frequently Asked Questions

Yes. The calculator, the charts, the goals, and the export are all free with no trial and no subscription. Ads support it, and a one-time in-app purchase removes them.

No. There is no account and nothing syncs to a server. Your entries are stored encrypted on your device, and the app collects no data about you and shares none with anyone.

BMI is a simple ratio of your weight to your height. It is a rough screening measure, not a diagnosis: it cannot tell muscle from fat, and it does not account for build, age, or body composition. Two people with the same BMI can be in very different health. Use it as one number among several, and talk to a doctor about what it means for you.

Yes. Set a target weight and the app shows a trend line through your entries with an estimated date at your current pace.

Yes. Export your full history as CSV to open in a spreadsheet or hand to a doctor, and use the JSON backup to restore everything when you move to a new phone. Your data is yours to take.

Completely. Every calculation and every chart runs on your device, so the app works with no signal at all.
