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.
