LastDrop Rx tracks your injectable medication vials — GLP-1s, insulin, and other injectables — so you always know exactly how much is left, when your next dose is due, and how your treatment is going. Your active vial's fill level is there the moment you open the app, changing color as supply runs low. Log a dose in seconds, record where you gave it, and keep every vial's lot number and expiration date in one place. VIAL SUPPLY YOU CAN TRUST • Live fill level for every vial, with low-supply and expiration alerts • Doses-left count and a refill estimate based on how you actually dose • Track several medications and several vials at once • mL, units and mg, with automatic concentration conversion • A dose drawn from two vials is measured correctly DOSE LOGGING FOR REAL SCHEDULES • Weekly, daily, multi-daily, or specific weekdays • Mark Taken, or snooze an hour, four hours or to tomorrow — from the notification • Record the injection site and a private note on any dose • Log Dose shows the last four sites you used for that medication • Dosed early? LastDrop offers to skip just the next reminder • Press and hold a past dose to fill in its site or note later • Import doses from Apple Health, then add their site and note from a notification MORE AT ONCE ON IPAD AND IPHONE DUO • Where there's room, medications beside their details, and doses beside each one's site, note and weight change • Medication details and Weight in two panes when there's room, divided at the fold on a partly folded iPhone Duo • Close iPhone Duo and keep your place on the cover display WIDGETS AND LOCK SCREEN • Vial Fill, Stats and At a Glance — fill level, doses and days remaining, dosing intervals, and your last and next dose • Current Weight, Trend Chart and Goal Progress — a 30-day chart with your goal line, and a progress ring with your pace • Lock Screen widgets in all three shapes, so your supply is on the screen you already check • Quick Log takes you straight from the widget to logging a dose or a weight SIRI AND SHORTCUTS • "Log my dose in LastDrop" • "Undo my last dose in LastDrop" • "How many doses are left in LastDrop" • "When is my next dose in LastDrop" • "Skip my next reminder in LastDrop" • "Check my days of supply in LastDrop" • "Log my weight in LastDrop" • Every action works in Shortcuts too — add a vial or build your own automation WEIGHT AND PROGRESS • Interactive charts measured from the starting weight you choose • Milestones, goals and a celebration when you reach one • See the weight change that accompanied each dose and each vial • Optional nutrition and body composition from Apple Health COMPREHENSIVE REPORT Build a clear PDF of your history to bring to an appointment. Open it from any medication, choose any date range, and pick exactly which sections to include — doses, vials, weight, nutrition — before anything is shared. Each report picks up where your last one for that medication ended, so no period is covered twice. ON-DEVICE INSIGHTS Plain-language summaries of your own logged data, written privately on your device. In English, Apple Intelligence writes them where it's available and turned on, and LastDrop writes them otherwise. In Spanish, French, German and Portuguese, LastDrop always writes them itself. They state facts from your history: never advice, never a diagnosis. FIVE LANGUAGES English, Spanish, French, German and Portuguese (Brazil) — the whole app, including the on-device summaries. PRIVACY FIRST LastDrop Rx collects zero data. No analytics, no ads, no third-party SDKs. Your health data never touches our servers — it stays on your device and in your own private iCloud account, syncing securely across your iPhone and iPad. LastDrop Rx is a personal tracking tool. It does not provide medical advice and is not a substitute for your prescriber or pharmacist.
