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.
