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.

Verdict
The clearest difference is in-app purchases: JIYU at none against Weight Diary's 1. JIYU also leads on update cadence (every 2 weeks vs every 5 months) and iOS requirement (13.4 vs 15.6). On price, ads and device support there is nothing between them.
