The Phaze medication screen showing the dose cycle as a ring, labelled Building Up at 67 percent with 11 hours 59 minutes to the next dose, and a note that the medication is slowly entering the system.

Built for Zepbound users.

Every feature is built around the GLP-1 journey on tirzepatide.

Dose tracking

Log each tirzepatide 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 Zepbound, 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 Zepbound.

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 Zepbound journey without ever revealing your medication.

Estimated Levels & Taper Coach

See the tirzepatide doses you log drawn as one curve across the cycle, with phase labels and a nudge when a dose is missed. Plan titration and step down with the Taper Coach. Not medical advice.

New

Labs & Scans

Track your labs across 8 categories, GLP-1, Metabolic, Lipids, Vitamins, Kidney, Liver, Thyroid, and Inflammation, alongside your Zepbound journey. Manual entry is free; OCR import of lab documents is a Pro feature. Always discuss results with your provider.

Body Composition (Beta)

Get an AI photo estimate of your body fat % and muscle, with a confidence level and a ±3–5% margin, now part of Labs & Scans. DEXA import is also supported. It's an estimate, not a medical measurement.

Saved meals & My Report

Save your go-to Zepbound meals for one-tap re-logging, and generate My Report, a shareable PDF of weight, nutrition, doses, side effects, and more, to bring to your appointments. It's a wellness summary, not a medical document.
