Tracking Wegovy means one weekly shot, a five-step titration ladder that runs for 16 weeks before maintenance, rotating injection sites, and watching how weight, nausea and food noise respond after each step. Peppy counts down to shot day, advances the dose when a step ends, suggests the next site on a body map, and pairs a daily weight and side-effect check-in with every shot.

## What tracking Wegovy actually involves

A Wegovy tracker app is mostly a titration tracker for the first four months, then a habit tracker after that. Wegovy is a once-weekly semaglutide pen in milligrams, no mixing, no syringe, so the work is remembering the day, rotating the site, and knowing exactly which step you are on. Wegovy's prescribing information lays out the injection schedule as weeks 1 to 4 at 0.25 mg, weeks 5 to 8 at 0.5 mg, weeks 9 to 12 at 1 mg, weeks 13 to 16 at 1.7 mg, and from week 17 a maintenance dose of 2.4 mg (or 1.7 mg for some patients). Five different pens over 16 weeks is exactly the kind of thing people write on a fridge note and then lose.

| Wegovy - catalog dose ladder | Dose |
| --- | --- |
| Step 1 | 0.25 mg |
| Step 2 | 0.5 mg |
| Step 3 | 1 mg |
| Step 4 | 1.7 mg |
| Step 5 | 2.4 mg |

Dose steps as listed in the Peppy catalog so the picker is fast - **not a recommendation**. Your prescriber sets your dose; Peppy tracks it.

That is the ladder as listed in the Peppy catalog for [Wegovy](https://peppytracker.com/compounds/semaglutide-wegovy/). Your prescriber decides the pace; Peppy keeps the current step visible so the number on the card matches the pen in your hand.

## Shot day, rotation and missed doses

Wegovy's label says to inject in the abdomen, thigh or upper arm and to rotate sites with each dose. Peppy's front/back body map has 13 sites and suggests the next one when you open the log sheet, with "last used" under every spot so you never guess. Rotation is shared across protocols if you track more than one thing. The [injection site rotation guide](https://peppytracker.com/guides/injection-site-rotation/) covers the order.

The missed-dose rule in Wegovy's current label is phrased around your next scheduled dose: if you miss one and the next dose is more than 2 days away, take the missed one as soon as possible; if the next dose is less than 2 days away, skip it and resume on the regular day. If two or more consecutive doses are missed, the label says to reinitiate escalation at a lower dose, which is a prescriber conversation. Peppy gives you the facts for that conversation: an "OVERDUE" state on the Today tab with the hours elapsed, and the Calendar view to log late, skip or add a past dose. Read the [missed GLP-1 dose guide](https://peppytracker.com/guides/missed-glp-1-dose/) for each label's rule side by side.

## Titration and step-ups

This is the feature Wegovy users use most. In Peppy, titration (Pro) is a list of steps with a duration each. Enter the five-step ladder your prescriber gave you and the dose advances automatically when each four-week block ends: the protocol card, the reminder text and the prefilled dose on the log sheet all change together. If your prescriber pauses you at 1 mg for an extra month because of nausea, you extend that step and the rest shift. Each step-up drops a marker on the weight chart, which is how you later answer "did the jump to 1.7 mg do anything". The [titration schedule tracker guide](https://peppytracker.com/guides/glp-1-titration-schedule-tracker/) walks through it.

## Side effects and weight

Weight is the number most Wegovy users care about, and Peppy treats it as part of the daily check-in rather than a separate app. Enter it once a day, or let Apple Health supply it from a connected scale; every weigh-in you type in Peppy is written back to Health. The check-in also scores nausea, constipation, heartburn, sulfur burps and food noise from 1 to 5, plus how you feel and a note. Add any of the other side effects (headache, fatigue, dizziness, hair loss) from Settings if they matter to you.

The Progress tab (Pro) draws the weight trend against your goal with a marker at each step-up, a side-effect heat-map by week, and an adherence percentage. Many people report that [food noise](https://peppytracker.com/side-effects/food-noise/) fades in the days after a shot and returns before the next one; the heat-map is how you check whether that is true for you. The [GLP-1 weight tracker guide](https://peppytracker.com/guides/glp-1-weight-tracker-apple-health/) covers the Apple Health setup.

## What's still active

Semaglutide's elimination half-life is approximately one week according to its prescribing information, which is why a weekly shot keeps a fairly level amount in your system. Peppy draws that as an "Active in your system" curve from the catalog half-life: it decays through the week and steps up when the next shot lands. An estimate from the half-life, not a measurement, but useful for seeing why a missed week shows as a dip rather than a cliff.

## Frequently asked

### Is there a Wegovy tracker app for iPhone?

Yes. Peppy is a free iPhone Wegovy tracker app. Wegovy is in the catalog as a weekly semaglutide pen with its dose ladder, so setup is a search: pick it, set your shot day and current dose, and log each shot on the body map.

### How do I remember my Wegovy day?

Set the weekday in the protocol and the Today tab counts down to it. With Pro, Peppy sends a reminder on the day and a missed-dose nudge 30 minutes, 1 hour or 2 hours later; the Next Shot widget on your Lock Screen logs it with one tap.

### Can the app track my Wegovy titration schedule?

Yes. Titration (Pro) is a list of steps with durations, 0.25 mg for 4 weeks, 0.5 mg for 4 weeks and so on. When a step ends the dose advances on the card, the reminder and the log sheet, and a marker appears on your weight chart.

### How do I track weight loss on Wegovy?

Enter your weight in the daily check-in or let Peppy read it from Apple Health. The Progress tab (Pro) draws the trend with your goal line and a marker at each step-up, so you can see how weight moved after every dose change.

### Does a Wegovy tracker help with food noise?

Food noise is one of Peppy's default GLP-1 check-in items, scored 1 to 5 each day. Over weeks the heat-map (Pro) shows whether it fades after each step-up or creeps back before shot day.
