Hit your goals with the smartest GLP-1 tracker, built for Ozempic®, Mounjaro®, Wegovy®, Zepbound®, Foundayo™, and any other GLP-1 medication. Sage Weight supercharges your GLP-1 journey. • Syncs with Apple Health: Weigh in on your smart scale and Sage picks it up automatically. Your weight history is stored securely in your Sage account and stays in sync with Apple Health, so it is safe across devices. You choose which apps can import weights, and you can remove any entry you don't want. • Never Miss a Dose: Reminders are delivered as Time Sensitive, so they break through Focus and Do Not Disturb. Tap a reminder to log your dose in one step. Edit, delete, or backdate a dose and your next reminder updates automatically. • Dose Efficacy Analysis: Go beyond basic tracking with a breakdown of your weekly weight loss by dose level. See exactly how well each dosage is working and make informed decisions with your healthcare provider. • Weight Projections: Sage uses your past trends to forecast future progress, including estimated time to goal weight, changes in pace, and weekly weight fluctuations. • Goals and Milestones: Set your target weight range and watch your progress. Hit a new low, cross a milestone, or reach a checkpoint and Sage celebrates with you. Change your goal and you start earning fresh milestones toward it. • Your Starting Point, Your Choice: Measure progress from your weight at first dose, your highest weight, or a custom weight you enter yourself. • A Weight Chart You Can Explore: Touch and drag to see the exact weight, date, and time of any entry, or tap one to pin it. Every weigh-in is marked on the Week, Month, and Year views. • Activity Feed: Your full history of doses, weights, side effects, notes, goals, and milestones in one scrollable timeline. Filter, sort, and group to find what you need. • Comprehensive Tracking and Insights: Monitor weight trends, track side effects, and see the complete picture of your health journey with clear visual summaries and actionable insights that go far beyond simple logging. • Made by a GLP-1 User for GLP-1 Users: After months on GLP-1s, I was frustrated. I found myself navigating forgotten doses, inconsistent progress, and juggling multiple tracking apps without getting much in return. So I decided to build something better. Sage is the companion I wish I'd had, built around ease, clarity, and efficacy. And it's only going to get better.
