Built for Retatrutide users.

Every feature designed around retatrutide and your unique needs.

Protein-First Tracking

Retatrutide's triple-action mechanism drives the fastest weight loss of any GLP-1 medication. Phaze sets aggressive protein targets (0.8–1.2g/lb) and tracks every gram to preserve muscle during rapid loss.

Triple-Agonist Dose Tracking

Retatrutide targets GIP, GLP-1, and glucagon receptors simultaneously. Phaze tracks your dose cycle with pharmacokinetic profiles designed for this next-generation medication.

Habit Streaks That Stick

Build the hydration, movement, and nutrition habits that carry you through retatrutide's powerful dose escalation and beyond medication entirely.

Progress Photos & Milestones

Retatrutide results can be dramatic and fast. Capture every stage with guided comparison photos and shareable milestone cards — medication info stays hidden.

Phaze Progression System

Move through personalized stages adapted for retatrutide's aggressive timeline — from early dose adjustments through maintenance and post-medication life.

Privacy by Design

Your retatrutide data stays encrypted on your device. Phaze looks like a premium fitness app — nothing reveals you're using weight loss medication.

Dose Increase Planner

Plan your next Retatrutide dose increase during onboarding or anytime. Pick from retatrutide-specific dose options or enter custom. Get notified 3 days before and on the day — then apply, snooze, skip, or plan next right from your home screen.

Weight Loss Pace Tracking

Set your weekly goal pace and see how you're tracking on Retatrutide. Actual vs. goal pace with a live completion badge. Weekly recaps compare your pace with on-track indicators. Fall behind 3+ weeks? Phaze gives you a personalized plan.

iCloud Backup & Restore

Retatrutide + Phaze FAQ

Retatrutide is a next-generation triple-agonist from Eli Lilly that targets GIP, GLP-1, and glucagon receptors simultaneously. Clinical trials have shown up to 24% body weight loss — more than any other weight loss medication. Phaze is ready to support your retatrutide journey.

While tirzepatide (Mounjaro/Zepbound) targets two receptors (GIP + GLP-1), retatrutide targets three (GIP + GLP-1 + glucagon). The glucagon component increases energy expenditure and fat burning, producing greater weight loss in trials. Phaze tracks your journey on either medication.

Given retatrutide's aggressive weight loss, 0.8–1.2g of protein per pound of body weight is recommended to preserve lean muscle mass. Phaze calculates your personal target and makes hitting it effortless with AI meal scanning.

That's exactly what Phaze is designed for. The V-to-L system builds sustainable habits during medication so you maintain your results after stopping. This is critical with retatrutide given its powerful effects.

Yes! Core features are free forever: dose tracking, nutrition logging, the Phaze system, streaks, milestones, and Apple Health sync. Premium ($4.99/month or $29.99/year) adds AI meal scanning, unlimited photos, and more.
