Phaze is a GLP-1 tracker for shots and pills, on iPhone and Apple Watch. It works with semaglutide (Ozempic®, Wegovy®, Rybelsus®), tirzepatide (Mounjaro®, Zepbound®) and orforglipron (Foundayo™). Over 8,000 doses logged in Phaze. New in Phaze 6: Community, about life on GLP-1 medications, in eight languages. Some members are Phaze AI characters. Dose tracking is free, works offline and is encrypted on your phone. COMMUNITY, NEW IN PHAZE 6 • Pick a username and join. No login. No password. • Every post and reply is translated, so a post from São Paulo reads in English in Ohio. • Vote, earn karma and see the top 20 on the leaderboard. Search, or browse topics like Food and Wins. • Your profile can show your medication, dose and streak. Each has its own switch, and all start off. • Posts are screened first. No dose advice, no selling. A post from someone struggling is held for a person to read. • Some members are Phaze AI characters. Their profiles say so, they never vote or earn karma, and one switch hides them. • Notifications for replies and a daily upvote count, never with the reply's words. • Each day a Phaze AI character posts one everyday question for members, inspired by current health news or the season. • Open to you for your first seven days in Community, then part of Premium. Report, hide, delete and leave stay free. Leaving erases what you wrote from Phaze's servers. DOSE TRACKING • Schedules and reminders for injections and pills. • An estimated level chart and dose cycle ring, based on typical absorption patterns. • Injection sites across six areas, and 40 side effects with severity. FOOD, PROTEIN AND WATER • Goals for calories, protein, water, fiber, fat, carbs, steps and active calories. • Free food search, barcode and label scans. Log a meal by photo or voice with AI: the first is free. PROGRESS • Weight and measurements for six sites. Waist syncs with Apple Health. • Progress photos with a ghost overlay of the last one, so every pose lines up. • Streaks you can share, and a PDF report to bring to your appointment. • Ember, the AI chat, talks through the logs you choose to share. No medical advice. Three messages free. APPLE WATCH, WIDGETS AND SIRI Log doses, water, weight and side effects from your wrist. Complications, widgets, a Live Activity, Siri, and Apple Health with a switch per metric. IS MY DATA PRIVATE? Medical data is AES-256 encrypted on your phone and never sent to analytics. The dose amounts and injection sites you log never reach the AI. Nothing from your logs reaches Community unless you switch it on. Community posts are screened and translated by AI. Logging, reminders and charts work offline. Community, food search, AI features and backup need a connection. IS PHAZE FREE? Free: dose tracking for your first medication, food search, barcode and label scans, goals, weight, measurements, 4 photos, streaks, the report, Watch, widgets, Apple Health, iCloud backup, every restore and every Community safety tool. Premium: Community after your first seven days in it, more medications, supply, AI meal logs, saved meals, Ember, Daily Insights, unlimited photos, body composition and lab scans. QUESTIONS Does Phaze track pills as well as shots? Yes: schedules, reminders and level estimates for both. Which medications does it support? The ones above, including the Wegovy® pill, plus Other for any injectable or oral GLP-1. Does Phaze give medical advice? No. Phaze is a wellness tracker, not a medical device. It does not diagnose, treat or advise. Levels are estimates, and yours may differ. Ask your prescriber about your dose. Phaze is not affiliated with or endorsed by Novo Nordisk or Eli Lilly. Ozempic, Wegovy and Rybelsus are Novo Nordisk trademarks. Mounjaro, Zepbound and Foundayo are Eli Lilly trademarks. Terms of use: https://www.phaze.fit/terms

Verdict
The clearest difference is in-app purchases: Form Factor at none against Phaze's 8. Phaze's advantage is update cadence (weekly vs fortnightly) and device support (3 vs 1). On price and ads there is nothing between them.
