Logging your weight takes 3 seconds. Open the app, tap +, done. Weight Diary is the simplest way to track your weight — every entry lands on a color-coded calendar, so a whole month of progress is visible at a glance. • Calendar view — entries appear as colored cards on each day, turning your month into a picture. • Context tags — log up to 5 entries a day, tagged Fasted, After meal, Workout, or Other. • Smart filters — show only your fasted weigh-ins to see your true trend. Toggle any context on or off, in both calendar and stats. • Trend charts — see your change over 7 days, 1 month, or 3 months, with period change and average at a glance. • BMI — calculated automatically from your height and weight, with healthy-range guidance. • Your units — switch between kg·cm and lb·ft anytime. • No sign-up — everything stays on your device. No account, no ads. [Premium] Unlock 6-month and 1-year trends, plus viewing and editing entries older than 3 months, with a Premium subscription. • Subscriptions renew monthly and can be cancelled anytime in iOS Settings > Apple Account > Subscriptions. Payment is charged to your Apple ID account, and the subscription renews automatically unless cancelled at least 24 hours before the end of the current period.
