TrendCut: Weight Trend Tracker

Your scale lies. The math doesn't. Weigh yourself two mornings in a row and the number can swing half a kilo either way — water, salt, sleep, a late dinner. None of that is fat. TrendCut runs every weigh-in through a statistical trend engine that separates the noise from the signal, so you can see the direction you are actually moving. HOW IT WORKS, IN ONE SENTENCE Each weigh-in updates a running estimate of your true weight and its rate of change — one odd morning nudges that estimate slightly, a real shift moves it decisively — and nothing is ever deleted or rewritten. Your raw entries stay exactly as you logged them. WHAT YOU GET • Trend chart — your smoothed trend line over the raw daily dots, with a shaded band showing the expected range, your goal line, and a short projection once the direction is clear. • Your real rate of change — weekly change read as a rate, in kg or lb per week, not yesterday minus today. • Plateaus, decoded — TrendCut calls out an active plateau and the phase it detects, instead of leaving you to guess whether two flat weeks mean anything. • Confidence, stated out loud — every read carries a confidence level and the reason for it. Thin or sparse data lowers confidence; it never sharpens the verdict. • Apple Health sync — reads your existing body-weight history, including smart-scale weigh-ins that already land in Health, and writes your manual logs back so your record stays in one place. • Sunday weekly report — a frozen trailing-week summary of trend, weekly rate and goal progress with a short plain-language read. Logging on Sunday never rewrites the report you already saw. • Full history — every entry editable, grouped by week, with optional context tags for travel, salt, training, illness and more. NO STREAKS. NO SHAME. JUST SIGNAL. No badges, no confetti, no streak to protect, no red number punishing a bad morning. Weight is data, not a moral score. TrendCut reads like an analyst, not a coach. WORKS WITHOUT AN ACCOUNT Everything is stored on your device first, and manual logging works with no account and no Apple Health history. Sign in only if you want your data backed up and synced across devices — and delete your account, and everything in it, from inside the app whenever you want.
