Weight trends, minus the noise. Your scale weight jumps around. Water, sodium, carbs, a late dinner, travel: day-to-day swings can hide weeks of real progress, or show progress that isn't there. TrendWeight draws a smoothed trend line through your daily weigh-ins, so you can see where your weight is actually going. An AI reads each morning's weigh-in and explains the change in plain language. WEIGH IN, DONE Log your weight in seconds with a wheel picker. Add optional tags (salty food, alcohol, poor sleep, travel, period) so the AI knows the context behind the number. THE TREND LINE, NOT THE NOISE The chart smooths your daily weigh-ins into one trend line, a moving average of your scale weight. A salty dinner stops looking like failure, a good week stops hiding behind water weight, and you can tell a real plateau from a few days of retention. AI INSIGHTS, EVERY DAY Each day's first weigh-in gets a short explanation: why the scale moved, whether the change is real or water weight, and how your week is trending. No arithmetic, no guilt trips. Works for weight loss, maintenance, and muscle gain. GOAL WEIGHT AND ETA Set a goal weight and see your weekly rate of change plus an estimated arrival date, calculated from the trend, not one good day on the scale. SMART SCALE IMPORT If your smart scale syncs to Apple Health, TrendWeight imports those weigh-ins automatically. Manual logging works just as well. BUILT FOR PRIVACY No email, no account needed to start. Your weigh-ins stay yours, and you can delete everything in one tap. Optional Sign in with Apple backs up your history for when you switch phones. ALSO INCLUDED kg and lbs, full history of every reading, offline logging. SUBSCRIPTION TrendWeight Pro unlocks the trend line, the daily AI read, and your full weigh-in history. Monthly: $9.99 per month. Yearly: $29.99 per year, which works out to $2.50 per month. Prices are in US dollars and vary by country. Your Apple Account is charged when you confirm the purchase. The subscription renews at the same price unless you turn off auto-renew at least 24 hours before the period ends. Manage or cancel it in Settings, under your name, in Subscriptions.
