About
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.
