Track your whole GLP-1 journey in one place — doses, meals, weight, side effects, and every win in between. Tonic is built for how your body actually changes on Wegovy, Zepbound, Ozempic, and Mounjaro. WHAT YOU CAN TRACK • Weight, measurements, and progress photos — watch your story unfold • Meals by photo*, barcode, or voice — log a real meal in seconds, not minutes • GLP-1 doses, injection sites, and dose-day reminders so you never miss a shot • Side effects like nausea, fatigue, and mood — catch the patterns early • Workouts, steps, and activity, synced from Apple Health WHY TONIC Most weight apps were built before GLP-1 existed. They count calories, guilt-trip you over streaks, and miss the point. Tonic connects your dose, your symptoms, your meals, and your weight into one story — because on a GLP-1, that's how it all moves together. • Built for GLP-1 from the ground up — Wegovy, Zepbound, Ozempic, and Mounjaro all supported • Works without medication too — plenty of people start with Tonic before their first shot • Two-way Apple Health sync — your data stays under your control • Sign in with Apple — no passwords, no email lists • No ads. Ever. BUILT FOR REAL DAYS Side effects and plateaus come with the territory. Tonic owns the hard days, celebrates the ones worth celebrating, and never guilts you for a missed log. Log when you can — Tonic meets you where you are. PRIVACY FIRST Your weight, your meals, your medication — they're yours. Tonic keeps your data private and never sells it. Only anonymous diagnostics ever leave the app, and only to fix bugs. WORKS WITH APPLE HEALTH Tonic reads what you choose to share — weight, activity, nutrition, workouts — and writes weight and water back, so your timeline stays in sync across your devices. You approve every data type, one at a time. START IN UNDER A MINUTE Tell Tonic where you are on your journey, log your first weight, and you're in. The plan moves as you do. SUBSCRIPTION & LEGAL Tonic offers an auto-renewing subscription. Payment is charged to your Apple Account at confirmation of purchase.
