## What is Peptrend?

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.

## Version history (last 3 releases)

### 1.5.0 — 2026-10-05

More than one medication. Moving from one medication to another, or taking a second one alongside? Pick it from the new Medication menu when you add a shot. Peptrend asks whether you're switching or taking both, and every dose you've already logged keeps its own medication's half-life.

Also in this version:
- The In System chart draws each medication as its own line. They are never added together.
- The Next Shot card follows each medication on its own schedule and lists what else is coming up.
- Settings > Medication shows your main medication and your other ones, with an Add button.
- A dose logged under a brand name, such as Ozempic, sits on the same line as its generic.
- The dose field in the Add sheet is labelled, with its unit.

### 1.4.0 — 2026-09-20

Athlete Mode. A new optional tab charts the fitness readings your watch writes to Apple Health, such as VO2 max, heart rate variability and resting heart rate, with your doses colored across them. Turn it on in Settings.

Also in this version:
- Orforglipron (Foundayo) now uses the half-life, time to peak and absorption from its FDA label.
- Numbers typed with a comma decimal save correctly in every region, and a pasted 1,000 reads as a thousand.
- The dose and weigh-in editors say why Save is unavailable.
- Trend lines animate when you switch methods, and the chart controls fold away as you scroll.
- The Ozempic and Rybelsus source links work again.

### 1.3.3 — 2026-09-08

No release notes.
