About Weightly: Trend & BMI Diary
See the trend, not the noise. Your weight jumps around every day — water, salt, sleep. Weightly smooths those swings into one honest trend line, so you always know where you're really heading. No account, no ads, and your data stays on your devices. SMART TREND • Exponentially weighted moving average that handles missed days • Weekly rate and an honest date range for your goal — not a promise • Plateau detection that tells you when things are simply steady APPLE HEALTH & SMART SCALES • Two-way sync with Apple Health, without duplicates • Works with any scale whose app writes to Health (Withings, Renpho, Eufy, Garmin and more) • Body composition, steps and sleep as context LOG IN SECONDS • Interactive Home Screen widget: adjust and save without opening the app • Lock Screen widgets, Control Center control and Apple Watch with Digital Crown • Siri and Shortcuts: "Log my weight in Weightly" — also with the Action Button MORE THAN THE SCALE • Goals to lose, gain or maintain within a range • Waist, hips, chest and more; private progress photos with comparison • GLP-1 & medication log with injection sites, reminders and a PDF for your clinician • Hide numbers: show only the direction, or hide values entirely • Import from Libra, Happy Scale, Renpho or Withings; export CSV/JSON anytime • Face ID lock, iCloud sync, kg / lb / st, dark mode, 6 languages WEIGHTLY PRO (OPTIONAL) Everything above is free. PRO adds Insights (weekly & monthly recaps, weekday pattern, streaks), goal milestones, a progress report PDF, photo timelapse videos, progress widgets and color themes. Your first week of PRO is a gift: it starts automatically, needs no payment and simply ends. Afterwards PRO is available as a weekly, monthly, 3-month or yearly auto-renewing subscription (with a welcome price on your first period) or a one-time lifetime purchase. Payment is charged to your Apple Account. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period; manage or cancel them in your Apple Account settings.
