The curve is an educational estimate, not a measured level and not dosage guidance. PREPARE FOR YOUR NEXT APPOINTMENT (PRO) Turn your entries into a PDF doctor report with your dose history, weight and documented symptoms, and bring it to your appointment. MEDICATION INFORMATION IN CONTEXT (PRO) Information on semaglutide and tirzepatide, plus research context for retatrutide. Retatrutide is investigational; its inclusion is not a recommendation to use it. The app does not recommend medication. INJECTION SITES IN 3D Record where you injected on an interactive body model. Your selection becomes part of your entry. The app does not recommend where to inject next. PRIVATE ON YOUR DEVICE Your health entries are stored locally. No app account, no sale of your entries and no advertising tracking. Lock the app with Face ID, Touch ID or your device passcode. Export CSV or JSON, restore a JSON backup, or delete your local data in the app. Health entries do not sync between devices. PRO SUBSCRIPTION Basic tracking, reminders, your archive, CSV/JSON export, backup restore and privacy controls remain available without Pro. PDF doctor reports, the knowledge area and educational drug-level charts require Pro. Pro is available monthly or annually. Subscriptions renew automatically and can be cancelled anytime. The price, billing period and any eligible introductory offer appear before purchase. Restore purchases is available. GLP Compass is a personal journal. It does not diagnose conditions or provide dosage or treatment recommendations. Discuss medical questions with your clinician or pharmacist.

Simple GLP is the fastest, most private way to log your GLP-1 medication, whether it's a weekly shot or a daily pill. It's free, needs no account, and takes a minute to set up. Built for people who just want the dose recorded, not another subscription or a spreadsheet. ONE TAP TO LOG Open the app, tap the Home Screen widget, or raise your wrist with Apple Watch. Your dose is timestamped instantly. Add dose, injection site, notes, and symptoms later if you want. WEEKLY SHOTS Ozempic, Wegovy, Mounjaro, Zepbound, compounded semaglutide or tirzepatide, or your own. Set your dose plan, weekday, and time. Simple GLP marks each shot early, on time, or late and reminds you before the next one. DAILY PILLS Wegovy pill, Rybelsus, Foundayo, or your own. One tap logs today's pill and starts a wait timer you set to match your prescriber's instructions, with a notification when it's done. The countdown also shows on the widget and Apple Watch. A daily reminder skips days you've already logged, and a streak and week view show how the routine is going. FREE, WITH NO ACCOUNT Logging, reminders, history, the pill wait timer, and insights are free and stay free. No sign-up, no login, no email. PRIVATE BY DESIGN No accounts. No ads. No analytics. No data sold. Your history and any captured Health context stay on your device, shared between the app, widget, and watch through a secure App Group. OPTIONAL HEALTHKIT CONTEXT With your permission, Simple GLP can attach context from Apple Health (weight, glucose, activity, sleep, heart rate, workouts, water, caffeine, calories, and protein) to each dose. Read-only. Never written back. SIMPLE GLP PRO (OPTIONAL) Everything you need to log is free. Pro adds the wait countdown on your Lock Screen and in the Dynamic Island, supply tracking with a refill heads-up before you run out, and missed-dose and timing alerts. Subscribe in-app. Cancel anytime in Settings. NOT A MEDICAL DEVICE Simple GLP records what you tell it you took and when. It does not provide medical advice, dosing instructions, diagnosis, or treatment recommendations. Always follow your prescriber's guidance. Subscription Details Simple GLP Pro is available as an auto-renewing subscription (Monthly or Yearly, both with a 7-day free trial) or as a one-time Lifetime purchase. Prices are shown in the app before you buy and vary by region. Payment is charged to your Apple ID at confirmation. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in Settings → Apple ID → Subscriptions.
