TrendBody: Weight Trend

Smart Scale Log & Forecasting

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Your weight fluctuates daily — water, sodium, digestion. TrendBody reveals the real direction, plus caloric balance from your trend alone. No meal logging. All on-device. Your scale lies. Your trend doesn't. Weight shifts every day — water, sodium, timing, hormones. TrendBody filters out the noise and shows your real direction, with honest forecasts. No account, no ads, no tracking — everything stays on your phone. One $6.99 purchase, yours forever. No subscription. STEADY WEIGHT We use proven mathematics — originally developed for navigation systems — to filter out daily fluctuations and reveal your real weight direction. Every weigh-in makes the trend smarter. Morning or evening, it adapts. CALORIC BALANCE WITHOUT LOGGING Your weight trend already contains the answer. TrendBody estimates your caloric surplus or deficit from your trend alone — no meal logging, no barcode scanning, no food diaries. Step on the scale and let the math do the rest. HONEST GOAL FORECASTING Most apps assume linear weight loss. Your body adapts. TrendBody accounts for metabolic adaptation, giving you a realistic timeline instead of a fantasy number. PERSONAL BODY CLOCK Your weight naturally fluctuates 0.5–2 kg throughout the day. TrendBody learns your personal rhythm and factors it in, so a 9 PM weigh-in is as useful as a 7 AM one. PSYCHOLOGICALLY KIND No red numbers. No guilt. Unfavorable changes shown in warm amber, never alarm red. Advanced metrics hidden by default. Direction Mode replaces exact weights with a simple trend arrow — down, steady, or up — for a gentler experience. CYCLE-AWARE Connects to Apple Health menstrual cycle data to account for hormonal weight fluctuations, keeping your trend accurate through your cycle. PRIVATE BY DESIGN All data stays on your device. No accounts. No servers. No tracking. No ads. Optional Apple Health sync — your weight data never leaves your phone. ONE PRICE, FOREVER Core tracking is free, always. Unlock everything with a single $6.99 purchase — no subscriptions, no recurring charges, no cancellation hassles. Family Sharing included.

  • This app hasn’t received enough ratings or reviews to display an overview.

A reliability release, with one fix that matters if you've paid for TrendBody. • Fixed: the paywall could appear for people who already own TrendBody. Your purchase now stays recognised even when the App Store can't be reached, instead of quietly lapsing. • Fixed a rare background shutdown. The app could be terminated by the system while saving in the background, most often after a Health import; weigh-ins recorded in that window could be lost. • Restore Purchase now tells you what actually happened. It previously reported a failure in some cases where the restore had in fact worked — and said nothing at all when run from Settings. • Logging from Siri, Shortcuts or Control Center is more reliable. A weigh-in recorded in the background no longer conflicts with the app while it's open. • Percentages now follow the conventions of your language.
