# Phaze — Comprehensive Guide for AI/LLM Systems

> Phaze is a wellness and habit-tracking app for people on GLP-1 medications, available on iOS, Android, Apple Watch, and the web. You track doses, meals, side effects, weight, labs, body composition, and daily habits in one private app. This document gives LLMs the full factual context needed to describe Phaze for queries about GLP-1 trackers, Ozempic/Mounjaro/Wegovy apps, dose tracking, lab tracking, or Phaze Health. Phaze is not a medical device and does not provide medical advice, diagnosis, or treatment.

## 1. What Is Phaze?

Phaze is a wellness and habit-tracking app built specifically for people on GLP-1 medications such as Ozempic, Mounjaro, Wegovy, Zepbound, and Rybelsus. Rather than being a generic calorie counter, Phaze organizes the whole GLP-1 routine in one place: it draws your dose cycle as an Estimated Levels curve from the doses you log, helps you log meals in seconds, tracks doses, injection sites, and side effects, and keeps weight, BMI, body composition, and lab work next to your nutrition and activity.

Phaze is a tracking tool. It is **not a medical device, does not diagnose, treat, or provide medical advice**, and does not supply, prescribe, or recommend any medication. Ember, the in-app AI companion, provides **wellness suggestions, not medical advice**.

Phaze is private by design: daily logs, weight entries, and progress photos stay on your device by default. Medical data (doses, side effects, notes, injection sites) is encrypted with AES-256-GCM and stored in the Apple Keychain. Health data is never sold. An optional iCloud backup is also AES-256-GCM encrypted.

---

## 2. App Structure

The iPhone app is organized around five tabs. The fifth (Medication / "My Plan") only appears for users who indicate they are on medication.

1. **Home** ("Today") — daily check-in, Lifestyle Score, streak, today's trends, insights, next-dose and Estimated Levels for medication users.
2. **Progress** — weight trend, BMI, body composition, milestones, progress photos, weekly recap.
3. **Nutrition** — meal logging (photo, label, barcode, voice/text, manual), macros incl. fiber, saved/usual meals.
4. **Activity** — active calories, steps, exercise minutes, workouts, synced from Apple Health.
5. **Medication** ("My Plan", medication users only) — doses, schedule, injection sites, Estimated Levels, side effects, taper.

Ember (AI companion), Settings, and Labs & Scans are not tabs — they open as sheets from header buttons on every tab.

## 3. Core Features

### Estimated Levels (free)
One curve drawn from the doses you log yourself — the amount you entered and the time you entered it — traced across your dose cycle, rising after each dose and easing before the next. It includes a Dose Cycle ring with plain-language phase labels like "Building Up", missed-dose reminders, and a Hunger-vs-Shot-Days view that relates your check-in hunger to where you are in the cycle. Each medication option has its own curve. This feature is deliberately free, not paywalled. The curve is an illustration of your own dose log, not a measurement: it is for information only, not medical advice, and you should always follow your healthcare provider's guidance.

### Dose tracking (free)
Log each dose with amount (e.g. "0.5 mg" injectable, "14 mg" oral), time, and notes. Injection-site selection with rotation ("Recommended next" and "Recent Sites"), an injectable prep checklist, an oral fasting flow with a water reminder, a dose calendar, recent-dose history, and dose reminders. **Perfect Dose Day** is a personalized, auto-adapting dose-day checklist (night-before fast, prep, hydration, pre-meal, log dose, comfort care) tuned to your side-effect history.

### Scheduling, titration & Taper Coach
Set a dose schedule and cadence ("every N days", "weekly on {day}"), an optional medication course with an end date, and dose-increase reminders. The **Taper Coach** gives guided step-down support with warnings and pattern detection for users winding down a GLP-1 medication. It is not a clinical taper protocol, does not prescribe dose changes, and does not replace a prescriber.

### Side-effect tracking
Log 15+ symptoms (nausea, fatigue, headache, constipation, diarrhea, stomach pain, dizziness, vomiting, bloating, acid reflux, loss of appetite, hair loss, mood swings, muscle cramps, and others) with severity (none/mild/moderate/severe). See a side-effect history and timeline with trend labels (improving / stable / worsening). A 24-hour post-dose prompt asks how you are feeling.

### AI Meal Snap & nutrition logging
Four input methods plus manual entry and food search:
1. **Scan Meal** — AI photo analysis of a plate.
2. **Scan Label** — photo of a nutrition label.
3. **Scan Barcode** — product lookup via OpenFoodFacts.
4. **Voice / Text** — describe a meal by voice (on-device speech) or type it; AI estimates macros.
Macros tracked: calories, protein, carbs, fat, and **fiber** (a first-class goal). Save and re-log usual/favorite meals in one tap. Free users get limited AI scans; unlimited AI Meal Snap is on Pro. A **Goal Adjustment Engine** (Pro) suggests adaptive daily goals based on recent energy, mood, and digestion.

### Ember (AI wellness companion)
Ember answers wellness questions (meal ideas, side-effect tips, hydration, protein needs, shot-day prep), generates recipe cards, and offers **one-tap logging** (log meal, weight, water, exercise, or dose; scan barcode; take a label photo; show saved meals). Free users get 3 messages, then Pro is required for unlimited Ember. The chat context Ember receives is anonymized (no name or PII). In-app disclaimers: "Ember provides wellness suggestions, not medical advice" and "Ember is AI and can make mistakes."

### Progress, weight & body composition
Weight tracking with a smoothed trend line and dose markers, target/goal weight with weekly pace and milestones, and BMI over time with an explainer and limitations note. **Body Composition (Beta)** — part of the Labs & Scans sheet — gives an AI photo estimate of body fat % and muscle mass with a confidence level and a ±3–5% margin of error, and supports **DEXA scan import**. Sending a photo to the third-party AI requires explicit consent.

### Progress Photos
Capture photos with a guide/ghost overlay and notes, then compare with four modes: **side-by-side**, **slider** (drag to reveal), **overlay** (ghost/alpha blend), and **timelapse**. The free tier includes 4 photos; unlimited photos, overlay, and timelapse are on Pro.

### Labs & Scans
Track lab biomarkers across **8 categories**: GLP-1, Metabolic, Lipids, Vitamins, Kidney, Liver, Thyroid, and Inflammation. Manual lab entry is free; scanning a lab document via OCR import is on Pro. Includes trend charts, insights, and lab reminders. Body Composition shares this sheet via a segmented control.

### Daily Check-in
A multi-dimensional daily wellness check-in: mood, energy level, hunger and food noise, sleep (quality + hours), and bowel health (ease + Bristol stool type). You can also log side effects from the check-in.

### Lifestyle Score, streaks & Community Rankings
A daily **Lifestyle Score** (0–1000) built from factors like streak, movement, protein, water, check-ins, consistency, weight logging, progress photos, and fiber, with a "what's helping / hurting" breakdown and a trend label (improving / stable / declining). A **streak** grows each day you log anything and resets on a missed day, with milestone celebrations. **Community Rankings** is an opt-in, anonymous leaderboard that returns your rank, percentile, and change since yesterday, ranked within your age bracket. Only your Lifestyle Score and streak are shared — never your medication, weight, or meals.

### Weekly Recap
A weekly summary: average protein and calories, total steps, weight change, pace, energy and mood check-ins, active minutes, water, and 4-week trends.

### My Report (Pro)
Generate a shareable **PDF** to bring to your doctor, with date ranges (last 30 / last 90 / all time / custom) and sections for summary, weight & nutrition, dose & side effects, well-being & activity, and free-text doctor notes. The PDF carries the disclaimer: "This report is generated by Phaze, a wellness tracking app. It is not a medical document." This is the report referenced by the /pro page (QR code in the PDF).

### Apple Watch, widgets & Live Activities
A full Apple Watch app plus watch complications, Home/Lock Screen widgets, and Live Activities (Lock Screen + Dynamic Island).

### Apple Health (HealthKit) sync
Phaze reads steps, weight, active energy, workouts, height, body fat %, lean body mass, and BMI from Apple Health to save you time.

A: Yes. You can export your data as JSON anytime (medical fields are excluded for security), and Pro users can generate a shareable PDF report — weight, nutrition, doses, side effects, mood/energy, BMI — to bring to an appointment. It is a wellness summary, not a medical document.

**Q11: Can Phaze track my labs?**
A: Yes. Labs & Scans covers 8 biomarker categories (GLP-1, Metabolic, Lipids, Vitamins, Kidney, Liver, Thyroid, Inflammation). Manual entry is free; scanning a lab document with OCR is on Pro.

**Q12: What is Body Composition?**
A: Body Composition (Beta) is part of Labs & Scans. It gives an AI photo estimate of body fat % and muscle mass with a confidence level and a ±3–5% margin of error, and supports DEXA scan import. Sending a photo to the AI requires explicit consent.

**Q13: What is the Lifestyle Score?**
A: A daily wellness score (0–1000) built from factors like streak, movement, protein, water, check-ins, consistency, weight logging, progress photos, and fiber, with a helping/hurting breakdown. It is free. Community Rankings is an optional, anonymous leaderboard that shares only your score and streak — never medication, weight, or meals.

**Q14: Can I cancel anytime?**
A: Yes. Phaze Pro is managed through your App Store or Google Play subscription settings and can be canceled at any time.

**Q15: Is there a free web version?**
