Best Reminder Apps for a Weekly GLP-1 Injection (2026): Apple Health, Samsung Health, Medisafe, MyTherapy, Shotsy

How We Compared the Apps

We looked only at features that matter for a once-weekly injectable (and for people who have since moved to a daily oral GLP-1). We didn't rate the apps on design or invent scores. Every fact on this page comes from the app's App Store or Google Play listing, the company's help center, or an official newsroom post, all checked October 20, 2026. App features change often, so confirm the details in the current listing before you rely on one.

• Weekly scheduling. Can it remind you on one specific day each week, without a workaround?
• Missed-dose follow-up. Does it nudge you again if you don't log the dose?
• Refill reminders. Will it warn you before you run out of pens, given pharmacy and prior-authorization delays?
• Caregiver or family sharing. Can a partner or adult child see or manage the schedule?
• Injection-site log. Does it record where you injected so you can follow the rotation your instructions describe?
• Travel and time zones. Does it handle a trip without silently moving or dropping a reminder?
• Platform, cost, and where the data lives. Is it free, and who holds your medication history?

Apple Health Medications: Best If You Use an iPhone

Apple's Medications feature lives inside the Health app on iPhone and iPad, with a Medications app on Apple Watch. You add a medication by name (in the U.S. you can also scan the label with the camera), choose its form and strength, and pick a schedule. For a weekly injection, the schedule that matters is “On Specific Days of the Week.” Apple's support page notes that this schedule type, along with cyclical schedules, needs iOS 18, iPadOS 18, or watchOS 11 or later. On an older device, the medication shows “Schedule Unavailable,” and you'd have to use a different schedule type.

Two details make it a strong default for a weekly pen. First, you can turn on follow-up reminders, which alert you if you haven't logged the medication 30 minutes after the first notification. Once follow-ups are on, Apple's iPhone guide says you can also turn on Critical Alerts for each medication. These appear on the Lock Screen and play a sound even when the phone is muted or a Focus is on, which helps for a reminder that only comes once a week. Second, if you change time zones, the Health app tells you and asks you to confirm your schedule, which is exactly when weekly doses tend to slip. You can export a PDF of your current medications for an appointment, and in the U.S. the app checks for interactions among the medications you've entered. Apple notes the feature isn't a substitute for professional medical judgment.

Samsung Health Medications: The Built-In Option on Galaxy Phones

Samsung launched a Medications tracking feature in Samsung Health in the U.S. in late 2023. According to Samsung's announcement, you can log prescription and over-the-counter medications, see descriptions and interaction warnings, and set reminders to take and refill them. Reminders can be a gentle pop-up or a strong full-screen alert with a long tone, and Galaxy Watch owners get them on the watch. A later update added pill-bottle scanning and a view of taken and missed doses. Samsung's announcements don't spell out the exact schedule options, so check when you set it up that you can pick a single weekday for your injection. If you can't, use one of the apps below.

Medisafe: A General-Purpose Pillbox With Family Features

Medisafe is one of the longest-running medication reminder apps. It is free to download with in-app purchases, and it runs on iPhone, Apple Watch, and Android. Its App Store listing highlights refill reminders, time-zone support so reminders stay on schedule while traveling, U.S. drug-interaction warnings, syncing with Apple Health, PDF progress reports to share with a clinician, and family pillboxes synced in one account. For a weekly shot, Medisafe's help center describes adding the medication as “On a recurring cycle” and setting a custom cycle of take days and break days, such as 1 and 6. One catch: custom cycles can only be set when you add a medication as a new entry, not by editing an existing one. If you set up a weekly pen the wrong way, delete it and add it again.

MyTherapy: Injection-Site Log and Family Profiles

MyTherapy, from smartpatient GmbH, runs on iPhone, iPad, and Android. Its App Store listing describes flexible medication reminders with snooze options, a daily log and calendar, refill and prescription reminders, an injection-site tracker, weight and symptom diaries, reports to bring to appointments, and family profiles for managing a loved one's routine in the same account. The company's page for weight-loss injections says it reminds you of the day and time of your injection, tracks titration steps, and keeps an injection log so you know where you last injected.

On money and data: MyTherapy says the app is free to use and will stay free. It says it pays for this through partnerships with pharmaceutical companies and health institutes, that it does not hand personal data to those partners or other third parties without consent, and that it is certified to the ISO 13485 and ISO 27001 standards. If that funding model matters to you, read its privacy policy before you sign up.

Shotsy: Built Specifically for GLP-1s

Shotsy is a GLP-1-specific tracker on iPhone, iPad, and Android (the iOS version needs iOS 18 or later). Its listing says it supports weekly injections and daily oral GLP-1s, with schedules, countdowns, reminders, and next-dose notifications, plus logs for dose history, side effects, weight, calories, protein, and water. It can track more than one medication on separate schedules. On iOS, Shotsy says your data is stored on your device and synced across your devices through your private iCloud, and that it never sells your data. That's worth knowing if you'd rather your medication history not sit on a company server.

Shotsy and several other GLP-1 apps also show “estimated medication levels” over time. Shotsy says its charts are based on peer-reviewed clinical data and describes the app as for tracking and education, not medical advice. We don't evaluate those charts. Treat them as a curiosity, not a guide to when or how much to inject.

Which One Fits Your Situation

You have a recent iPhone and just want a reliable nudge

Use Apple Health Medications with a specific-day schedule and follow-up reminders turned on. There's nothing to install, and no new account holds your data.

You rotate injection sites and want a record

MyTherapy has a dedicated injection-site log, and Shotsy logs doses alongside side effects and weight. Rotate sites the way your medication's Instructions for Use describes. The app only keeps the record.

A partner or adult child helps manage the schedule

Medisafe's family pillboxes and MyTherapy's family profiles are built for this. With Apple Health, a family member can see shared medication data through Health sharing. Our caregiver guide covers the permissions side.

You travel across time zones

Apple Health prompts you to confirm your schedule after a time-zone change, and Medisafe advertises time-zone support. Before a trip, decide which local time you'll use for injection day, and ask your pharmacist if a long trip shifts your schedule. See traveling with a GLP-1 for the cold-chain side.

You keep running out because of pharmacy or insurance delays

Turn on refill reminders (Samsung Health, Medisafe, MyTherapy) early enough to cover a prior-authorization renewal or a backorder. Our guides to prior authorization and shortages explain why a week of buffer helps.

Setting Up Any Reminder App: A Short Checklist

• Pick an injection day and time you can keep most weeks, ideally one that isn't usually your busiest day.
• Enter the medication exactly as it appears on the pharmacy label, so the log matches your records.
• Turn on a follow-up or snooze reminder, and make sure the app is allowed to send notifications (and, on iPhone, Critical Alerts if you choose to use them).
• Set a refill reminder with enough lead time for your pharmacy, and for prior-authorization renewals if your plan requires them.
• Log the dose when you take it, not later from memory.
• Write down the missed-dose instructions from your medication's official patient information somewhere you can find them, outside the app.
• After every phone upgrade or operating-system update, check that reminders still fire.
