Keep your medication routine and health trends together. Vially is a local-first tracker for adults 18+ using GLP-1 medications—including Zepbound, Wegovy, Ozempic and Mounjaro—plus peptides, TRT, insulin and oral medications. Replace scattered notes with one organized view of schedules, dose history, symptoms, labs and progress. MEDICATION TRACKING Plans, Doses & Reminders Create multiple protocols, choose flexible schedules, set on-device reminders, and record completed, skipped or unscheduled doses with notes. Calendar & Adherence Review upcoming doses and your history in a unified calendar. See adherence summaries and track medication supply. Injection Site History Record the site used for each injection and review recent use to support a consistent rotation routine. CALCULATORS & LEVEL CHARTS Use peptide reconstitution and branded-vial calculators to work through concentration, dose volume and syringe units. Save setups and view modeled medication-level charts based on schedules, logged doses and half-life. PROGRESS & WELLNESS Weight, Measurements & Photos Track weight, BMI, body fat, body measurements and goals. Compare progress photos and view weight trends alongside dose levels. Side Effects & Check-ins Log symptoms with severity, timing and notes. Capture mood, energy and daily observations for your own record. Nutrition, Hydration, Sleep & Activity Quick-add protein, calories, fiber and water. Record sleep, steps and workouts, or connect supported Apple Health categories with your permission. Labs & Reports Enter lab results manually, compare dates, follow marker trends, and prepare a formatted doctor-visit PDF. Export a copy of your Vially data. OPTIONAL AI TOOLS After you review the per-report disclosure and tap Accept & Extract, AI Lab Scanner sends the complete report image or PDF to paid Google Gemini for reviewable extraction. Verify every candidate field before saving. AI Meal Scan sends a reviewed meal photo only after one-time, revocable consent and only when you tap Estimate with AI. Estimates remain editable. Aurora Coach answers general educational medication and habit questions. You choose whether compact summaries of selected records or recent messages accompany a question, with sharing controls available in Settings. Apple Health data and photos are never included in Coach requests. PRIVATE BY DESIGN Core health records stay on your iPhone. Vially has no user account or health-record cloud sync. Optional analytics is off unless you enable it. Vially does not retain scanner inputs or responses on its servers and does not keep a server-side Coach chat history. Google may retain paid-service requests and responses for up to 55 days for abuse monitoring. See the Privacy Policy for details.

They are not medical advice and do not diagnose, prescribe, select a dose, recommend treatment or replace a clinician or pharmacist.
