At Apple's request, dosage and reconstitution calculator features have been removed to meet App Store review requirements. Medication tracking and your saved records remain available. 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. 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 schedules, dose history, adherence and inventory. Injection Site History Record the site used for each injection and review recent use to support a consistent rotation routine. MODELED LEVEL CHARTS Review estimates based on recorded doses and published half-life data. These are not measured blood levels or dose recommendations. 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. IMPORTANT HEALTH INFORMATION Vially, modeled charts, scanners, meal estimates and Coach are for personal tracking and general information only.

Where precision becomes a practice. Nactara is the private dosing journal for adults running peptide protocols. Not a pharmacy. Not a marketplace. Not a coach. We do not recommend doses, suggest cycles, or interpret symptoms. Every number in the app was entered by you — Nactara just keeps it organized, calculated correctly, and quietly visible over time. If you've tracked protocols in spreadsheets, Notes, or memory, you know the cost of fragmented records — a missed dose is hard to spot, a vial that ran out is hard to remember, a side effect is hard to connect to anything. Nactara gives precision a single home, private on your device and synced encrypted only to your account. WHAT YOU GET Protocols, properly tracked. Define a protocol with one or many compounds, a frequency, and optional start/end dates. See "Day 23 of 90" at a glance. Pause cleanly when you cycle off; archive when you're done. Reconstitution calculator. A clean, deterministic mg ↔ mL ↔ mcg helper. Enter vial size and bac water; get concentration and target volume. No suggestions, no "recommended" amounts — just arithmetic you can trust. Vial inventory that updates itself. Log a dose; the matching vial deducts automatically. See estimated doses left, expiration, lot number, and reconstitution date. A low-stock banner warns you before you run out. Quick-confirm logging. Tap Mark taken on Today, confirm in a quick card, save. Suggestions from your past entries keep logging fast and accurate. Journal that anchors the data. Energy, mood, sleep, appetite, libido, weight, side effects, notes. Every entry timestamps with your dose history so patterns surface. Photos, side by side. Front, side, and back photos in encrypted storage. Compare month one against month three in a tap. Sync between iPhone and web. Phone in the morning, laptop at night — same data, protocols, and vials. Export the whole archive as JSON whenever you want. Privacy, the way it should be. Photos and labs are encrypted on your device before upload; the server stores ciphertext. We don't sell your data, share it with insurers, run ads against it, or train models on it. No community feed, no leaderboard, no friend graph. Your records are your records. Built for GLP-1s too: On a GLP-1 protocol? Log semaglutide, tirzepatide, retatrutide, and the newer incretins the same way you'd log any peptide — your dose, your weekly schedule, your private record. The reconstitution calculator handles compounded vials, and titration steps are tracked cleanly as you ramp. Same rule as everything else: Nactara never suggests a dose or a schedule. Every number is yours. A NOTE ON ETHICS: Nactara exists for adults already running protocols who want a better way to track them. We do not recommend doses, suggest cycles, prescribe, diagnose, or treat. We do not sell or partner with sellers of peptides, supplements, or compounded products. Nothing in the app is medical advice. Always work with a qualified clinician for any decision involving your body. FREE TIER: Nactara is free. Start with one protocol and one vial — fully tracked, with the calculator, journal, photos, history, and automatic vial deduction included. No countdown. No nag screens. Your data stays yours whether you subscribe or not. If you pause Pro later, every record stays visible. Additional protocols and vials become read-only — never deleted. You pick which one stays active without paying. Re-subscribe and everything writes again. PRO SUBSCRIPTION: Pro unlocks unlimited protocols and unlimited vials, with everything you've built carrying over. A 7-day free trial is available for first-time subscribers, full access included. Subscriptions auto-renew at the price shown at purchase; cancel any time from your iPhone Subscriptions settings. Renewal terms are shown clearly before purchase.
