Phaze, a new iOS app for GLP-1 medication users, is applying artificial intelligence and pharmacokinetic modeling to one of weight loss medicine's most persistent failures: the 68% of patients who regain weight within a year of stopping Ozempic, Mounjaro, or Wegovy, according to a peer-reviewed study published in the New England Journal of Medicine.
The GLP-1 market has produced blockbuster medications. It has not produced the software infrastructure to support them. Patients managing weekly injections, escalating doses, suppressed appetite, and unpredictable side effects have been left with generic fitness apps built for a different problem. Phaze was engineered specifically for this gap, combining clinical-grade data modeling with consumer-grade AI to turn a medication course into a lasting behavior change.
The app's technical centerpiece is a pharmacokinetic blood-level chart that no other consumer health application offers. Phaze calculates each user's medication concentration over time using dose superposition algorithms, the same modeling approach used in clinical pharmacology, and renders it as a real-time visualization on the user's device. Weight data and logged side effects overlay directly onto the chart, letting users identify patterns between their medication cycle and how their body responds. A companion hunger-vs-shot-days chart correlates appetite fluctuations with dose timing, giving users and their clinicians a data layer that previously existed only in research settings.
Nutrition logging is handled through AI voice parsing. Users describe a meal conversationally and the AI returns structured macro data in seconds, with no database searching or portion scrolling required. The in-app diet assistant operates with full context: it knows the user's current dose phase, remaining daily macros, calorie targets, and intake so far. Responses address GLP-1-specific realities such as appetite suppression, dose nausea, and protein preservation during rapid weight loss rather than offering generic dietary advice. Voice logging works alongside three additional input methods:
- Barcode scanning via the device camera
- A 300,000-item USDA and OpenFoodFacts database
- Manual entry with a precision portion picker
Phaze also generates three types of shareable PDF reports with a single tap:
- Personal record — full history for the user's own reference
- Physician report — clinical summary with referral QR code
- Nutritionist report — macro performance with referral QR code
Each includes weight trend graphs, medication compliance data, side effect timelines, and progress photos, closing the gap between patient self-tracking and clinical appointments.
"My doctor asked what changed. I showed her the PDF report from Phaze. She said she wished all her patients tracked like this." — Priya S., Mounjaro user
All processing runs on-device. Health data is encrypted with AES-256-GCM and stored locally, with no internet connection required for any core feature. Phaze is compliant with HIPAA, CCPA/CPRA, and FTC Health Breach regulations. The app supports more than 40 GLP-1 medications, carries a 4.9-star rating across more than 2,400 App Store reviews, and is available in eight languages.
Phaze is free to download. The Premium tier, which unlocks unlimited AI meal scans, unlimited AI diet chat, iCloud encrypted backup, advanced trend charts, and clinical PDF reports, is priced at $4.99 per month or $34.99 per year, with a seven-day free trial on the annual plan.
