Peptrend draws the trend line under your weigh-ins. Body weight swings several pounds a day on water, food, and salt. A single reading is a noisy sample of a slow-moving signal, so Peptrend fits a smoothed line through your data and shows what is happening underneath it. THE TREND Choose how the line gets drawn: exponentially weighted moving average, the Hacker's Diet filter, a Kalman filter, Hull, DEMA and TEMA, rolling median, Kaufman's efficiency ratio, and more. Swipe between methods and watch the same weigh-ins redraw. Import your history from Apple Health or enter readings by hand. DOSES Log GLP-1 doses, injected or oral, and see an estimate of how much is still circulating based on that medication's half-life. Oral tablets are modeled with their own absorption, so a 14 mg tablet is not charted as 14 mg in your bloodstream. Moving to a different medication, or taking two at once? Each one keeps its own half-life and its own line on the chart. Log vials, reconstitution, injection-site rotation, and titration over time. GOAL PROGRESS Set a target weight and a date, or a steady weekly rate. A waterfall chart breaks progress down week by week, colored by the dose you were taking, so the weeks that moved are easy to tell apart from the ones that did not. ATHLETE MODE If you train, switch on Athlete Mode and a new tab charts what your watch already records in Apple Health: VO2 max, heart rate variability, resting and walking heart rate, cardio recovery, blood oxygen, exercise minutes and more. Each line is colored by the dose you were taking, so you can see the two side by side. Peptrend reads those numbers and never writes to them, and it does not claim that one causes the other. PRIVACY No account, no analytics, no advertising, no network calls. Weigh-ins live on your device and in your own private iCloud database, which we cannot read. The privacy manifest declares no collected data and no tracking. PEPTREND PRO Logging your weight and doses is free, and stays free. Pro adds the full set of trend methods, projections, energy-deficit estimates, the goal waterfall, and Athlete Mode. Seven days free, then $12.99 per month, $69.99 per year, or $99.99 once. Peptrend is not a medical device and does not diagnose, treat, cure, or prevent any medical condition, and it does not provide medical advice. Circulating-dose figures are estimates derived from published half-lives, not measurements of your blood. Decisions about your treatment belong with your prescriber.
