About

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
