Trendlo — Weight Trend Tracker
Daily Scale Log & Watch Widget
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Step on the scale daily; let Trendlo do the maths. A trend graph that smooths the noise, plus an Apple Watch complication showing your direction at a glance.
Log your weight in three taps from your Apple Watch the moment you step off the scale. Trendlo calculates a smoothed 7-day moving average and shows your trend direction as a Watch face complication — visible all day, every day.
• WATCH-FIRST LOGGING — Digital Crown weight entry, 3-tap save. Done before you leave the bathroom.
• TREND, NOT NOISE — Smoothed moving average filters out water weight, meal timing, and daily fluctuation. See the real direction.
• WATCH COMPLICATION — Your trend arrow on your watch face. Up, down, or stable — at a glance, all day.
• SPARKLINE DASHBOARD — 30-day trend sparkline on iPhone. See the shape of your progress.
• HEALTHKIT SYNC — Reads and writes body mass to Apple Health. Your data stays yours.
