Phaze vs Pep: two GLP-1 trackers, compared fairly
Pep (listed on the App Store as "GLP 1 Tracker: Pep" by Shred Apps) and Phaze are both GLP-1-specific tracking apps. They overlap a lot: doses for injections and pills, estimated medication levels, injection-site rotation, side effects, nutrition with an AI food scanner, weight, and progress photos. This page lines them up honestly so you can pick the one that fits how you track.
Pep facts are drawn from its public App Store listing and official site, accessed June 2026. Both apps are self-tracking tools, not telehealth services: neither prescribes, consults, or sells medication. Phaze is a wellness and habit-tracking app, not a medical device, and does not provide medical advice.
Feature comparison: where they overlap, where they differ
Both apps cover the GLP-1 tracking basics. The honest differences are in labs, body composition, Apple Watch, and a few coaching features, listed below with their source.

Pep covers the GLP-1 basics: its App Store listing confirms dose tracking for injections and pills, estimated medication levels, injection-site rotation, side-effect logging, reminders, nutrition with an AI Food Scanner, barcode scanning, hydration, weight, progress photos, Apple Health, and iOS + Android. Rows marked "not on Pep's listing" (Apple Watch, labs, body composition, Taper Coach, doctor PDF, AI companion) are simply not mentioned on Pep's public listing as of June 2026, not a claim that Pep cannot do them. We make no claim about Pep's encryption because its listing does not state one; the row reflects only Phaze's own AES-256-GCM claim.
Pricing: both free to start
Both apps are free to download with optional premium features. Pep's listing shows in-app purchases but does not map a single subscription price to each tier, so we describe it generically rather than guessing a number.
Phaze
Pep
We do not publish a specific Pep subscription price because the App Store lists in-app purchase price points without mapping them to monthly vs. annual or to specific feature unlocks. Treat both as "free core plus optional premium" and check each app's current in-app pricing before subscribing.
The honest differences between Phaze and Pep
Phaze and Pep are the same kind of app: GLP-1-specific self-trackers. Here are the differences we can actually source.
Same category, lots of overlap
Both are GLP-1-specific tracking apps, not telehealth programs. Neither prescribes, runs clinician consults, or sells medication. Pep's own disclaimer states it is "for informational and tracking purposes only." If you want a tracker rather than a prescribing service, both qualify, and they overlap on doses, estimated levels, injection sites, side effects, AI food scanning, nutrition, weight, and progress photos.
Labs and body composition
Phaze tracks lab work and scans across eight biomarker categories and includes an AI Body Composition estimate (Beta), plus DEXA import. Pep's App Store listing does not mention lab or bloodwork tracking or body-composition scans. If pulling your labs and body data into the same app matters, that is a real point of difference.
Apple Watch
Phaze ships a native Apple Watch app for logging doses, weight, water, and fasting, with complications. Pep's App Store listing does not list Apple Watch compatibility or a watch app. If wrist logging is part of your routine, this is worth checking on each app's current listing.
Coaching, reports, and privacy posture
Phaze adds a Taper Coach for stepping down, a My Report PDF to share with your doctor, the Ember AI wellness companion (wellness suggestions, not medical advice), and a Lifestyle Score, and it states a local-first, AES-256-GCM encryption posture. Pep's listing does not mention these specific features. We are only describing Phaze's claims here, not asserting anything Pep lacks beyond what its listing shows.
Phaze vs Pep questions
Pep is a self-tracking app, the same category as Phaze. Its App Store listing places it in the Medical category and its own disclaimer says it is "for informational and tracking purposes only." It does not prescribe medication, provide clinician consults, or sell medication. So this is a tracker-vs-tracker comparison, not tracker-vs-telehealth.
Quite a lot of the same things. Both track GLP-1 doses for injections and pills, show estimated medication levels over time, support injection-site rotation, log side effects, send custom reminders, track nutrition (calories, protein, fiber, fat) with an AI food scanner and barcode scanning, track hydration, weight, and progress photos, and integrate with Apple Health. Both are available on iOS and Android.
Based on Pep's public App Store listing as of June 2026, Pep does not list a native Apple Watch app, lab or bloodwork tracking, or body-composition scans. Phaze includes a native Apple Watch app, Labs & Scans across eight biomarker categories, and an AI Body Composition estimate (Beta) with DEXA import, plus a Taper Coach, a My Report PDF, the Ember AI wellness companion, and a Lifestyle Score. These are absences from Pep's listing, not a claim about what Pep is incapable of.
Both are free to download with optional premium features. Phaze offers free core features with an optional Phaze Pro upgrade. Pep is free to download with in-app purchases; its App Store listing shows in-app purchase price points but does not clearly map them to a single monthly or annual price, so we do not quote a specific Pep subscription figure. Check each app's current in-app pricing before subscribing.
If you mainly want doses, estimated levels, injection sites, side effects, and AI-assisted food logging, both Phaze and Pep cover that ground well. Choose Phaze if you also want lab and body-composition tracking, a native Apple Watch app, a Taper Coach, a doctor-ready PDF report, and a stated local-first, AES-256-GCM privacy posture in one app. Both are free to try, so you can install either and see which fits.
