Phaze is a wellness and habit-tracking app purpose-built for GLP-1 medications including Ozempic, Mounjaro, Wegovy, Zepbound, Rybelsus, semaglutide, and tirzepatide. Track your dose with Estimated Levels, one curve drawn from the doses you log yourself. Log meals by photo, label, barcode (OpenFoodFacts), or voice with AI Meal Snap. Rotate injection sites, plan titration with Taper Coach, and learn your side-effect patterns. Track weight, BMI, body composition (Beta), and lab work across 8 biomarker categories. Ask Ember, the AI wellness companion, for meal ideas and shot-day prep. Build a daily Lifestyle Score, streaks, and an optional anonymous ranking. Your data is local-first, with medical data encrypted using AES-256-GCM in the Apple Keychain. Apple Watch app, widgets, and Live Activities included. Supports 14 GLP-1 medication options across 8 languages. It is not a medical device and does not provide medical advice. Free on iOS and Android.

Principles

The Phaze difference

Not another fitness app. A calm, private place built for one thing: tracking the whole GLP-1 journey in one place.

  1. Built for the GLP-1 journey

    Estimated Levels, injection-site rotation, titration, and side-effect tracking — every screen is shaped around life on a GLP-1, not borrowed from a generic fitness app.

  2. Habits between appointments

    A daily Lifestyle Score, streaks, and check-ins build protein, hydration, fiber, and movement into your routine — so the habits keep going between prescriber visits.

  3. Private by design

    Local-first by default. Medical data is encrypted with AES-256-GCM in the Apple Keychain and isn't uploaded to our servers. It just looks like a calm health app.

  4. Free where it matters

    Dose tracking, the Estimated Levels chart, meal logging, check-ins, side-effect tracking, Lifestyle Score, and streaks are all free. Phaze Pro adds power tools when you're ready.

  5. Shaped by the community

    Features ship from real user feedback. The people building Phaze understand the GLP-1 journey because they live it too.

Estimated Levels

See your medication working.

426 members have logged doses across 4 or more separate weeks; 144 across 12 or more.

Building up

Every dose stacks on the one before it. Phaze draws the climb from the doses you actually log — no guessing where you are.

Peak

The steady stretch. Levels settle into a weekly rhythm and the curve flattens out between shots.

Tapering

Step a dose down and the curve redraws around the new plan, with Taper Coach and missed-dose guidance beside it.

Possible effects

  • Appetite suppression
  • Nausea

Estimated Levels draws every dose you log as a single curve across the cycle, with phase labels like "Building Up" and a nudge when a dose is missed. Log doses, rotate injection sites, and plan titration — for injectables and orals. The curve is an illustration of your own dose log, not a measurement. Not medical advice.

Nutrition

Eating right, made effortless.

The hard part of eating well on a GLP-1 isn't appetite — it's keeping up. Phaze makes capturing protein, fiber, and calories take seconds, not willpower.

Log it

Logging a meal takes one photo.

  1. Just say it

    "Two eggs, toast with butter, and coffee" — describe a meal by voice or text and Phaze estimates the macros. The fastest way to log.

  2. Snap. Log. Done.

    Photograph your plate and Phaze estimates protein, fiber, and calories — review and edit before you save. Eating well takes seconds.

  3. Scan a label

    Point your camera at a nutrition label and Phaze reads the macros. No typing, no second-guessing.

  4. Scan a barcode

    Scan any barcode for instant nutrition info, powered by OpenFoodFacts. Quick, accurate logging.

The Phaze “Log a meal” sheet: search foods, a voice button and a scan button, with one-tap recurring meals.
Free: limited scans • Phaze Pro: unlimited

21,167 meals and 24,283 waters logged in Phaze.

Labs & Scans

Weight is one number. Your body is the story.

On a GLP-1 the scale moves fast — but it doesn't tell you whether you lost fat or muscle. Phaze's Body Composition (Beta) gives you an AI photo estimate of body fat % and muscle, with a confidence level and a ±3–5% margin, plus DEXA scan import. It lives inside Labs & Scans, next to your weight.

  • AI estimate + DEXA import

    Get an AI photo estimate of body fat % and muscle (Beta), or import a DEXA scan with OCR. A confidence level and ±3–5% margin are always shown.

  • The metrics that matter

    Body fat %, muscle and lean mass, and fat mass — trended over time so you can watch the real change, not just the scale.

  • Body comp + weight, together

    See body composition alongside your weight trend. When the scale stalls but your composition shifts, you'll know it's progress.

4,521 body-composition entries and 4,674 weigh-ins logged.

The Body composition screen in Phaze, in dark mode. A metric selector across the top offers Weight, BMI, Body Fat, Lean Mass and Fat Mass, with BMI selected and reading 24.3 against a 28.3 average. Below it a coral area chart falls from 35 to about 24 across the full logged range, marked Jun and Dec, with the caption 'Down 10.3 over this range.'
Body composition in Phaze: weight, BMI, body fat, lean mass and fat mass, each on its own trend. Shown here, BMI across the full logged range. Values are illustrative.

Body Composition is a Beta feature and an estimate, not a clinical measurement — DEXA import is available for a more precise reference.

8 biomarker categories

Labs matter on a GLP-1 — A1C, lipids, kidney, liver, thyroid, and more. Phaze keeps them next to your weight and meals, across 8 biomarker categories, with plain-language context. It's a tracking tool, not medical advice.

When it stalls

Your home screen, paying attention.

Phaze notices patterns across your protein, hydration, sleep, side effects, and weight — only after enough data, and only when it matters.

  • Insight

    You hit your protein goal 6 days in a row — nice consistency.

  • Insight

    Your hydration tends to dip on Sundays. Want a Sunday nudge?

  • Insight

    Less than 6 hours of sleep often lines up with more hunger the next day.

  • Insight

    Your nausea has been easing over the last two weeks.

The median rate members record is 0.65 kg (1.4 lb) a week — within the commonly cited safe range.

n=256 members · 28+ days between weigh-ins · self-reported. Phaze is a tracker used alongside a GLP-1 medication, not the cause of these figures.

Patterns are shown only after enough data — never a diagnosis.

When you stop

Tapering off?You don't have to wing it.

Taper Coach watches your hunger and weight patterns as you step down and surfaces plain-language warnings — so you can adjust with your doctor. It informs that conversation; it doesn't replace it.

What Taper Coach watches

  • Pattern detection on hunger and weight as your dose lowers
  • Plain-language warnings before sudden drops or hunger rebounds
  • Works whether you're stepping down or stopping entirely
  • Private by design — your taper data stays on your device
Progress

Progress you can actually see.

Capture photos with a guide overlay and compare them side-by-side, with a slider, an overlay, or a timelapse — proof the scale can't show.

Privacy

Your data stays yours

Local-first by default. Medical data is encrypted with AES-256-GCM — in the Apple Keychain on iPhone, the Android Keystore on Android.

Where your data goes

Your phone

By default

Encrypted backup

Only if you ask

Nowhere else

Empty on purpose

    Medication details are stripped from analytics and from Ember's context.

  3. Local-first storage

    Your data lives on your phone by default. Backups are opt-in and go to your own iCloud or Google Drive — never to a Phaze server.

  4. Encrypted cloud backup

    Optional backups are AES-256-GCM encrypted before they leave your phone — to your iCloud or your Google Drive.

  5. Delete everything, anytime

    One action clears every log, on the device and in your backup. On iPhone you can also export your data as JSON (medical fields excluded).

  6. Apple Health sync

    On iPhone, Phaze reads steps, weight and workouts from Apple Health to save you time — with your permission.

The Complete GLP-1 Tracker

Phaze is a wellness and habit-tracking app for anyone on a GLP-1 medication like Ozempic, Mounjaro, Wegovy, or Zepbound. It is purpose-built for the GLP-1 journey, not a generic fitness app repurposed for weight loss. Phaze is not a medical device and does not provide medical advice, diagnosis, or treatment.

Ozempic Tracker

Phaze tracks your Ozempic (semaglutide) doses and shows Estimated Levels, an informational chart that draws every dose you log — the amount and the time you entered — as one curve across your cycle. It also logs injection sites with a rotation map, tracks side effects with severity and trends, and focuses on protein-first nutrition. The curve is an illustration of your own dose log, not a measurement, and is not medical advice.

Track Your Ozempic Dose

Phaze helps you track your Ozempic dose with a Dose Cycle ring that labels where you are in the cycle you logged, a titration and Taper Coach, dose reminders, and injection-site rotation. Medical data is encrypted with AES-256-GCM and stored in the Apple Keychain.

Mounjaro Tracker

Phaze tracks your Mounjaro (tirzepatide) journey with dose tracking, Estimated Levels, side-effect intelligence, weight and body-composition trends, and protein-first nutrition logging. Build daily habits with a Lifestyle Score, streaks, and check-ins.

Wegovy Tracker

Phaze supports both injectable and oral Wegovy, with an oral fasting flow, semaglutide dose tracking, Estimated Levels, injection-site rotation, and the full daily habit loop of logging, check-ins, and insights.

Zepbound Tracker

Phaze tracks your Zepbound (tirzepatide) doses, side effects, weight, BMI, and body composition (Beta), with AI meal logging to help you hit protein and fiber goals. Capture progress photos and compare them with a slider, overlay, or timelapse.

Semaglutide Tracker

Phaze supports semaglutide medications including Ozempic, Wegovy (injectable and oral), and Rybelsus, with per-molecule Estimated Levels, a fasting flow for oral forms, dose tracking, and side-effect trends.

Tirzepatide Tracker

Phaze supports tirzepatide medications including Mounjaro and Zepbound, with tirzepatide Estimated Levels, dose tracking, injection-site rotation, protein-first nutrition, and body-composition tracking.

Weight Loss Medication Tracker

Phaze supports 14 GLP-1 medication options including Ozempic, Mounjaro, Wegovy, Wegovy Pill, Zepbound, Rybelsus, Retatrutide, Survodutide, Orforglipron, Pemvidutide, Bioglutida, and CagriSema. Several newer molecules are investigational and not FDA-approved as of 2026; Phaze is a tracking tool, not a source or supplier. For each medication, Phaze offers dose tracking, Estimated Levels, side-effect tracking, nutrition, labs, and progress.

Every Number That Matters, in One Place

Phaze brings nutrition (calories, protein, carbs, fat, and fiber), weight and BMI, body composition (Beta, an AI photo estimate with a confidence level and DEXA import), Labs and Scans across 8 biomarker categories, and Apple Health activity into one app, so the picture is whole. Lab work and body-composition estimates are informational and not a substitute for medical care.

Why Phaze for GLP-1

Phaze is designed for GLP-1 users. It combines Estimated Levels, dose and injection-site tracking, side-effect intelligence, protein-first nutrition with AI meal logging, barcode and label scanning, body-composition tracking, progress photos, a Lifestyle Score, and Ember, an AI wellness companion that provides wellness suggestions, not medical advice. Phaze is local-first: medical data is encrypted with AES-256-GCM in the Apple Keychain. The core is free on iOS and Android, with Phaze Pro available.
