Peptide Vault is the tracking and research companion for people who take their protocol seriously. TRACK Track an FDA-approved GLP-1 (semaglutide, tirzepatide, and other approved GLP-1s): dose schedule, next-dose countdown, streaks, adherence, dose history, and reminders. Build the schedule you actually follow: every few days, chosen weekdays like Mon–Fri, or on/off cycles. BUILT AROUND YOUR SCHEDULE Pick your first dose day and your schedule patterns from it — weekly, twice weekly, three times weekly, every other day, or every two weeks. Log a dose in seconds. Your history lives on a calendar you can actually read. PEPTIDE VAULT PRO • My cabinet — save vial photos, ingredient amounts, mix dates and notes, with cabinet backup and restore. • Custom blend protocols — one schedule and one log for a multi-ingredient vial, with a recorded ingredient breakdown. • Coach — a research assistant grounded in your own protocol. Ask about the published research behind the compounds you track. Coach's answers are grounded in published research, and it never gives dosing or medical advice. • Track unlimited compounds across your whole protocol. • Open all 203 compounds in the research library — every entry referenced, with regulatory status, mechanisms, risks and side effects stated plainly. • Site rotation, suggested at every dose. • Dose history and trends across everything you run. • Journal with full record export, any time. COMMUNITY Join public conversations about app tips and staying organized. Posts and replies are moderated, with likes, sharing, reporting and blocking. Your optional Community profile and posts are stored on our servers; approved posts are public. Private tracking records are not posted automatically. Activity notifications are optional. YOUR DATA No account is required for private tracking. Your protocol, logs, and journal live on your device. Coach shares only what you approve — your compound names and stack summary, never your journal, notes, or Apple Health data. Peptide Vault is a tracking and reference tool. It does not provide medical advice, diagnosis, or treatment. Always consult a medical professional before using peptides.

Verdict
The clearest difference is review sentiment: Peptide Vault at 100% against Peptide Calendar's 0%. Peptide Vault also leads on rating (5.0 vs 1.0) and ratings volume (10 vs 1). Peptide Calendar's advantage is monetization model (freemium vs subscription) and update cadence (every 3 days vs weekly). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Peptide Calendar sells 2 in-app purchases, starting at $9.99 per month and Peptide Vault sells 10 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Peptide Calendar ships an update every 3 days, Peptide Vault weekly. The most recent releases landed on October 31, 2026 and November 5, 2026 respectively.
