PeptideStack
Read full descriptionHide full description
Track your peptide protocol, GLP-1 medication, and injection routine in one clean, private journal. PeptideStack is built for people who take their regimen seriously and want a focused log, not a spreadsheet and not a medical guide. YOU ENTER EVERY NUMBER PeptideStack never recommends, suggests or works out a dose. The dose field starts empty and is labelled "Your dose": you type your own amount, and the app simply records what you entered and when. WHAT YOU CAN DO • Build your stack from a curated catalog of 69 commonly studied peptides — BPC-157, TB-500, GHK-Cu, Semaglutide, Tirzepatide, Retatrutide, Cagrilintide, CJC-1295, Ipamorelin, MK-677, Tesamorelin and more — or add your own entries. • Log a dose fast: choose the peptide, type your amount, and save. A normal day takes seconds. • Get a reminder at the time you choose, on the days you choose. Reminders run on your phone and keep working offline. • Track the vial you are using: the amount in it, the date you opened it, a discard-after date, and how much is left based on the doses you log. • Follow a cycle: how many weeks in you are, and when the break starts. • Record how you are doing — body weight, sleep, energy, recovery — and watch the trend on a chart. • Export your dose history and your progress to a spreadsheet whenever you want. • Review your full history, grouped by Today, Yesterday, Earlier this week, and Earlier. • Add a note to any dose — what you noticed, how you felt, anything worth remembering. • Change your password any time from Settings. • Use it in your language: English, German, French, Spanish, and Arabic, with full right-to-left layout for Arabic. WHO IT IS FOR • People keeping a personal record of a peptide regimen they manage themselves. • People tracking GLP-1 medication already prescribed by their healthcare provider. • Researchers, biohackers, athletes, and anyone who wants a clean log instead of scattered notes. PRIVACY FIRST Your stack and dose history are encrypted in transit and at rest, and tied to your account so nothing is lost when you change phones. We never sell your data. Delete your account from Settings at any time — your data is removed within the published grace window. PEPTIDESTACK PRO (OPTIONAL) Free: dose logging, your full history, one reminder, and up to 3 peptides. Pro adds: • Reminders on every peptide in your stack, not just one • Vial tracking — amount remaining and a discard date • Cycle tracking — the week you are in and when the break begins • Progress charts for body weight, sleep, energy and recovery • Export to a spreadsheet • An unlimited number of peptides • Monthly: $4.99 / month • Annual: $29.99 / year (save ~50%) • Lifetime: $79.99 (one-time) 7-day free trial on the subscription plans. Cancel anytime in Settings → Apple ID. Subscription auto-renews unless cancelled at least 24 hours before the end of the current period. IMPORTANT PeptideStack is an educational tracking tool. It does not provide medical advice or diagnosis, and it never recommends or suggests a dose — every dosage, frequency, and amount is one you entered yourself. You are responsible for your own decisions. Always consult a qualified healthcare professional before starting, changing, or stopping any peptide regimen.

Vialry

Vialry is a private tracker for the injections you already take: TRT, HRT, GLP-1 pens and vials, and anything else your clinician prescribed. Add a vial in about a minute, confirm each entry, and keep a plain count of what is left. YOUR VIALS IN ONE LEDGER - Name, amount and unit, plus lot, opened date and expiry when you have them - A plain count of what is left on each vial, pen or box, like a refill count - A low-supply marker you choose, shown on the bar - Start a replacement vial without losing the old one's history EVERY ENTRY CONFIRMED Pick the vial, type what you took, tap the spot on the body map. Nothing saves until you tap Confirm & Save. Apple Watch, widget and Shortcut actions open the same confirmation. REMINDERS FROM YOUR SAVED PLAN Save the schedule your clinician gave you and Vialry reminds you at those times. Late or skipped? Record what actually happened. APPOINTMENT SUMMARY Choose the date of your last visit, jot down your questions, and share one PDF: what you logged since then on page one, the full record after it. The first one does not need Pro. VIALRY PRO Charts of your last 28 days (how often you logged, which sites, what you noted), an alert at your low-supply marker, your choice of expiry lead time, repeat appointment summaries and history filters. Pay once with Vialry Pro Lifetime, or choose the yearly plan, which also adds encrypted backup and sync between your devices. PRIVATE BY DESIGN No account needed for the journal. No ads and no third-party tracking. The journal stays on your device unless you turn on encrypted backup (yearly plan, with Sign in with Apple), and you can export JSON or CSV at any time. Optional product analytics starts off and never carries a journal value. Vialry only keeps the values you type. It gives no medical advice and is not a medical device. For adults 18+. Vialry Pro Lifetime is a one-time purchase with no renewal. The yearly plan is an auto-renewing subscription: payment is charged to your Apple Account at confirmation, and it renews unless canceled at least 24 hours before the current period ends. Manage or cancel it in your Apple Account settings. Terms of Use: https://vialry.keenshift.ai/terms Privacy Policy: https://vialry.keenshift.ai/privacy

Verdict
The clearest difference is update cadence: Vialry at fortnightly against PeptideStack's monthly. PeptideStack's advantage is iOS requirement (15.1 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
