Weight Diary

Simple Weight Tracking

No guesswork or calorie counting required.
Simply enter your daily weight and let Weight Diary estimate your weekly loss and daily calorie change.

Full-Screen Interactive Graph

Display all your weight data in a single graph. Tap with one or two fingers to display your weight or see your weight change between any two dates.

Supports Popular Smart Scales

Sync with Apple Health or smart scales from FitBit and Withings to have your weight automatically imported each day.

Keep Your Weight Private

Add an optional passcode or use Face ID / Touch ID to unlock the app.

Smooth the Daily Ups & Downs

Our unique trend line shows your progress at a glance. If the line is sloping downwards and most of your weight entries are below the trend line then you are losing weight. Simple.

Summary & Daily Log

Track your trends and see your weight loss over the past week, month or longer in the summary view or drill down to individual weight entries and see your custom notes in the daily log view.

Choose Your Units

Pounds, kilograms or stones. We speak your language. Customize the sub-units to match your scale. We even support ounces if that’s how you roll!
