Pepdex is a peptide tracker. Log each shot on your own schedule, see the days left in every vial and get a reminder when the next one is due. You type in the amount of every shot yourself, and Pepdex never suggests one. That amount always comes from you and your clinician. FREE, NO ACCOUNT NEEDED • The peptide and supplement library, with evidence grades and the papers behind them • Plain English guides on peptides, supplements and nutrition • Coach answers from the catalog stored on your phone TRACK IT WITH PRO • Protocols on your own schedule for any peptide in the catalog, including GLP-1s, plus TRT or a compound you add yourself • A reminder when each shot is due, with an optional heads-up 30 or 60 minutes early • Vials that count down the shots and days left as you log, and a heads-up when one runs low • A one-tap shot log and a calendar of logged, planned and missed shots • Supplements, food, water, workouts, weight and daily check-ins • Scan a vial or supplement label to fill in a new entry, or photograph a meal for a calorie estimate A LIBRARY THAT SHOWS ITS RESEARCH Peptide and supplement entries are graded by how much human research PubMed holds on them, with links to the papers, reported side effects and cautions. Many peptide entries also list questions worth asking a provider. Entries the research can't grade explain why. It is educational reference, not medical advice. ASK COACH Coach is an AI assistant for questions about a compound, a side effect or what the research found. A free account gets 10 Coach messages a day, and Pro includes more. Without an account, Coach answers from the catalog stored on your phone. Coach sees a summary of your tracking only while "Let Coach see my numbers" is on. You can turn that off in Settings and keep using Coach. APPLE HEALTH With your permission, Pepdex reads weight, steps, sleep and other data you choose to share from Apple Health, and, if you turn it on, saves the water you log to Health. FREE AND PRO Free: the library and guides, and 10 Coach messages a day with a free account. Pro: tracking (protocols, vials, the shot log, shot reminders, supplements, food, water, workouts, weight and check-ins) and more Coach messages. Pro is an auto-renewing subscription with weekly, 3-month and annual plans. The 3-month and annual plans start with a 7-day free trial for new subscribers. Prices are shown in the app before you subscribe. Pepdex does not sell or ship peptides. It is an information and tracking tool, not medical advice. Talk to your clinician before you start, stop or change anything you take. Subscriptions auto-renew unless turned off at least 24 hours before the end of the current period. Payment is charged to your Apple Account at confirmation of purchase, or when a free trial ends. Manage or cancel in your Apple Account settings.

Verdict
The clearest difference is review sentiment: Pepdex at 100% against Peptides Calculator's 55%. Pepdex also leads on rating (5.0 vs 4.3). Peptides Calculator's advantage is ratings volume (175 vs 6). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Peptides Calculator sells 11 in-app purchases, starting at $9.99 per month and Pepdex sells 4 in-app purchases, starting at $5.00 per 7 days. Whichever you choose, the download price is not the number that matters.
Pepdex holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Peptides Calculator has 175 ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 55% of Peptides Calculator's written reviews are positive against 100% of Pepdex's.
Both ship on a similar rhythm, roughly every 5 days. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
