The apps, one by one
Shotsy GLP-1 Tracker
Shotsy is the most established dedicated GLP-1 tracker here. Its listing describes one-tap dose logging for injections and pills, several medications with separate schedules, estimated medication-level charts, side effects, weight, calories, protein and water from Apple Health, and iCloud sync across your devices. It is free to download with a subscription tier, so check what the free tier includes, and its listing shows iPhone only.
MeAgain: GLP-1 Tracker App
MeAgain adds a food log with photo, barcode and search, protein, fiber and water goals, a side-effect journal, progress photos and a home screen widget. It suits people who want one app for meals and doses. The listing says some features require a subscription, and that breadth means more to set up than a dose log needs.
Zepbound & Mounjaro Tracker (GlucoPal)
GlucoPal combines dose logging with an injection-site body map, weight trends, photo and barcode meal logging, side effects and progress photos. Its listing says no account is required and mentions private iCloud backup and sync. Estimated medication-level forecasts and PDF reports for appointments are in the optional Pro subscription.
Glapp: Smart GLP-1 Tracker
Glapp is the broadest in features. The listing describes a daily check-in for side effects, mood and sleep, a medication-level curve, a weekly progress report, comparison with clinical-trial data, nutrition tips and supply tracking that deducts each dose from your pens or vials. It also lists an Apple Watch app. It is the most to learn of the group.
Simple GLP: GLP-1 Dose Tracker
Jack Wallner's app. It logs a weekly shot or daily pill in one tap from the app, a Home Screen widget or Apple Watch, with reminders, history, a pill wait timer, an injection-site note and optional Apple Health context, all free and on your device. Pro adds Lock Screen and Dynamic Island countdowns, supply tracking and missed-dose alerts. Limits: no food log, no progress photos, no medication-level charts, and no iCloud sync, so your history lives on the device. It has 1 rating, so its score says little yet.
Which should you pick?
- You want estimated medication-level charts and the biggest user base: Shotsy.
- You want meals, protein and photos in the same app as your doses: MeAgain or GlucoPal.

- You want a fast dose log on your wrist and widget, with no account and nothing else to maintain: Simple GLP.
- You want your history synced between devices: choose Shotsy or GlucoPal, whose listings mention iCloud sync. Simple GLP keeps its log on one device.
