Retatrutide Companion App

Track your Retatrutide doses.

Retatrutide is an investigational triple-agonist (GIP, GLP-1, glucagon) and is not FDA-approved as of 2026. Phaze is a wellness and habit-tracking app, not a supplier or prescriber, that helps you log every dose, meal, side effect, and milestone privately in one place.

Built for Retatrutide users.

Every feature is built around life on retatrutide.

Dose tracking

Log each retatrutide dose with amount, time, and notes. Rotate injection sites with a recommended-next suggestion, follow a prep checklist, and see your Estimated Levels across the dose cycle, free, and for information only.

Side-effect intelligence

Log symptoms with a severity level and watch the trend over time (for example, 'nausea is decreasing'). A 24-hour post-dose check-in helps you notice patterns on Retatrutide, for your own awareness.

Fast, protein-first logging

Snap a meal with AI Meal Snap, scan a label or barcode, or just say what you ate. Protein-first with fiber as a first-class goal, plus saved meals you can re-log in a tap on Retatrutide.

Progress photos

Capture photos with a guide overlay and compare them side-by-side, with a slider, an overlay, or a timelapse. Share milestone cards from your time on Retatrutide without ever revealing your medication.

Estimated Levels & Taper Coach

See the retatrutide doses you log drawn as one curve across the cycle, with phase labels and a nudge when a dose is missed. Log a planned dose increase, and if you are coming off with your prescriber, the free Taper Coach keeps your logged weight in view. Not medical advice.

New

Labs & Scans

Track 8 lab categories, including GLP-1, metabolic, lipids, kidney, and liver markers. Enter values by hand for free, or import lab documents with Phaze Pro. Your trial protocol or prescriber decides which labs to monitor.

Body Composition (Beta)

Body Composition, now part of Labs & Scans, gives an AI photo estimate of body-fat percentage and muscle mass with a confidence level and a margin of error, plus DEXA scan import. It is an estimate, not a medical measurement.

Saved Meals & My Report

Save your go-to meals to re-log in one tap, and generate a shareable PDF of weight, nutrition, doses, and side effects to bring to an appointment. It is a wellness summary, not a medical document.
