Track your GLP-1 journey from your Apple Watch with Phaze.

• 8

  Side-effect tracking

  Log symptoms with severity in the iPhone app, and trends show whether they are easing or climbing over time.

Watch complications and widgets

Complications are the small Phaze tiles you can place directly on your watch face, and widgets do the same on your iPhone Home and Lock Screen. They turn a glance at the time into a quiet view of your day, instead of a deep menu you tap into. Pick a watch face that exposes complication slots and place Phaze there to keep your progress in view.

On Apple Watch, complications come in fixed shapes and sizes, circular, rectangular, inline, corner. Apple decides what fits where, and app developers fill the slots. Phaze complications are built so the things a GLP-1 user wants to glance at, your daily progress and your streak, sit on the right slot for each watch face. Picking the right complication for the right slot is the difference between a watch face you actually read and one with a Phaze logo nobody looks at. Phaze widgets do the same on your iPhone Home and Lock Screen.

Apple Health, the connective tissue

Phaze syncs with Apple Health so the numbers you already capture flow into your trends. It reads steps, weight, active energy, and workouts from Apple Health, which means activity logged anywhere on your devices shows up in Phaze without re-entering it. Your weight and activity trends in the iPhone app stay aligned with the rest of your health data, and the watch and widgets keep that picture close at hand through the day.

For the curious, the underlying connective tissue is HealthKit. Phaze reads steps, weight, active energy, and workouts from Apple Health, so the numbers you already capture flow into your trends without re-entering them. What it means for you is that your activity shows up in Phaze no matter which device or app recorded it.

The practical effect is calmer mornings. You step on a connected scale and the reading writes to Apple Health, then flows into your Phaze weight trend, with your GLP-1 dose markers overlaid so you can see the curve in context. You finish a walk and the active energy and steps land in Apple Health and feed your daily progress. Your watch complications and iPhone widgets keep that picture glanceable through the day, while the detailed tracking, doses, side effects, meals, and labs, lives in the Phaze iPhone app.

Live Activities for time-bound moments

Live Activities put a persistent card on your Lock Screen and in the Dynamic Island for moments that have a timeline, like following along with your dose day. They suit oral GLP-1 routines too, where the fasting window after a pill matters. For example, Rybelsus is taken on an empty stomach with only a small sip of water, per its FDA prescribing information. Phaze is a tracker, not a source of medical guidance, so always follow your healthcare provider and your medication's instructions.

The timing matters here because the absorption rule is short and easy to break. As an example, Rybelsus is taken on an empty stomach with only a small sip of water, per its FDA prescribing information. Phaze tracks oral doses with an empty-stomach flag, a fasting window, and a water reminder, and Live Activities keep time-bound moments glanceable on your Lock Screen and in the Dynamic Island. Phaze is a tracker, not a source of medical advice. For how Phaze handles stepping down a medication, see the Taper Coach page.

How Phaze fits among GLP-1 trackers

GLP-1 tracking apps overlap on the basics, dose logging, reminders, weight, and nutrition, and differ in what they add around them. Phaze is purpose-built for the GLP-1 journey, with an Estimated Levels chart based on published pharmacokinetics (free), dose tracking with injection-site rotation, side-effect tracking, progress photos, body composition, labs, an AI wellness companion named Ember, and an Apple Watch app with complications, widgets, and Live Activities. The table below sticks to capabilities we can describe for Phaze; we do not list features for other apps that we cannot verify from their current product.

This table lists what Phaze ships at time of writing. We do not characterize other apps' Apple Watch capabilities here unless we can verify them from their current product.

Setting up Phaze on Apple Watch

Install Phaze on iPhone first; the Watch app installs over the air automatically once your iPhone and Apple Watch are paired on watchOS 10 or later. Open Phaze on iPhone once to set your medication and plan. On Apple Watch, long press your watch face, tap Edit, and add a Phaze complication to a slot. You can also add Phaze widgets to your iPhone Home or Lock Screen for the same glanceable view.

1. 01

   Install Phaze on iPhone

   Grab Phaze from the App Store. The Watch app installs over the air automatically once iPhone and Watch are paired on watchOS 10 or later.

2. 02

   Open Phaze on iPhone, set your medication

   Open Phaze, pick your GLP-1 medication and dose schedule. Your plan and progress feed the watch complications and widgets.

3. 03

   Pick a watch face with complication slots

   Modular, Infograph, or any Siri-style face. You want at least one circular slot, and ideally a rectangular and an inline.

4. 04

   Add a Phaze complication

   Long press the face, tap Edit, choose a slot, scroll to Phaze, pick the variant you want.

5. 05

   Add iPhone widgets too

   Long press your iPhone Home or Lock Screen, add a Phaze widget, and your daily progress stays glanceable there as well. You are set.

From there, the rest of Phaze is iPhone-first, while the Watch and widgets keep your progress glanceable. If labs and body composition matter to you, see the Lab Tracker and Body Composition pages, both pair well with the Watch flow described above.
