Best GLP-1 Tracking Apps in 2026: Lumi vs Shotsy vs MeAgain vs Glippy (Full Comparison)

If you're taking semaglutide (Ozempic, Wegovy) or tirzepatide (Mounjaro, Zepbound), you need a tracker that actually understands GLP-1 routines — not a generic calorie counter with a weight chart bolted on.

This guide compares the most popular dedicated GLP-1 tracking apps in 2026, including Lumi, Shotsy, MeAgain, Glippy, and Medisafe, feature by feature.

What GLP-1 users actually need from a tracker

Most health apps were built for general fitness. GLP-1 tracking has different requirements:

• Injection scheduling — weekly dose tracking with site rotation, not daily pill reminders
• Weight trend analysis — understanding that GLP-1 weight loss is non-linear, with plateaus and fluctuations
• Food guidance for GLP-1 — knowing which foods work well with reduced appetite, not just calorie counting
• Symptom and side effect logging — nausea, fatigue, appetite changes tied to dose timing
• Menstrual cycle tracking — semaglutide and tirzepatide can affect cycle timing and flow
• Privacy — health data this personal should stay on your device

Most popular apps cover one or two of these. Very few cover all of them.

The apps compared

Lumi: GLP-1 Tracker

Built specifically for GLP-1 users. Lumi is a dedicated GLP-1 journal that combines injection tracking, weight trends, menstrual cycle history, daily check-ins, and food analysis in one app.

What sets it apart in 2026:

• GLP-1 Food Checker — point your camera at any food, drink, snack, or label and get instant guidance on whether it's a good choice, better in moderation, or worth limiting on a GLP-1 day. Powered by Apple Foundation Models, running entirely on-device.
• Polaroid photo sharing — generate shareable polaroid-style cards from your weight chart for milestones and progress updates.
• Menstrual cycle tracking — tracks cycle changes alongside dose and weight, which most competitors ignore entirely.
• On-device AI — calorie estimates and weekly summaries without sending data to external servers.
• One-time purchase — $5.99 with no subscription. No account required.

Platform: iPhone + iPad · Privacy: No analytics, no telemetry, iCloud sync only · Price: $5.99 one-time

Shotsy

The most popular GLP-1 tracker. Shotsy is the category leader with a polished interface, strong social presence on Reddit and TikTok, and excellent injection tracking.

• Best-in-class injection tracking and reminders
• Beautiful, shareable weight trend graphs color-coded by dosage
• Dose escalation timeline
• Side effect logging alongside dose history
• Estimated medication level charts (premium)
• Injection site rotation tracking
• No food database or nutrition tracking
• No menstrual cycle tracking
• No AI food guidance
• Apple Health sync behind the paywall
• No cloud backup — data loss risk when switching devices
• Android experience trails iOS

Platform: iPhone, Android · Price: Free tier / $9.99/month / $39.99/year

Shotsy is a polished medication tracker that does one thing well — shot tracking and weight graphing. But it has zero nutrition features. No food database, no meal logging, no calorie or protein tracking. For an app designed for people on weight loss medication, that's a notable gap. Privacy concerns have also been raised following their 2025 funding round.

MeAgain

All-in-one GLP-1 routine tracker. MeAgain is the second most popular GLP-1 app with 372,000+ users and a 4.8-star App Store rating across 17,000+ reviews. It covers shots, food, side effects, and more.

• Shot and pill tracking with dose history
• Injection site map with rotation memory
• Five food logging methods (photo, barcode, voice, search, quick-add)
• Protein, fiber, and water tracking
• 18 common GLP-1 side effects with severity slider (0–10) plus unlimited custom symptoms
• Weight trend tracking
• Progress photos and Journey Cards
• Estimated medication level chart
• Capybara home screen widget
• No menstrual cycle tracking
• No on-device AI food analysis
• Hard paywall — no free features at all
• Account required
• Also sells compounded semaglutide ($129/month) and tirzepatide ($199/month) in-app

Platform: iPhone, Android · Price: $4.99/week (~$20/month) or $39.99/year. No free tier.

MeAgain is the most feature-rich competitor. It tracks nearly everything a GLP-1 user needs — but the pricing is steep. At $4.99/week, you'd pay over $250/year. There's no way to try the app without paying first, and the in-app medication sales blur the line between tracker and telehealth provider.

Glippy

The only 100% free GLP-1 tracker. Glippy launched from the GLP-1 community and offers core tracking features with no paywall at all.

• GLP-1 injection tracking
• Estimated medication level charts
• Weight, calories, protein, water tracking
• Apple Health sync
• Side effect tracking
• Export data (PDF and CSV)
• Built-in community for accountability
• No food scanner or AI analysis
• No menstrual cycle tracking
• iOS only — no Android
• Newer app with smaller user base

Platform: iPhone only · Price: Free (ad-supported)

Glippy is the best option if you want free GLP-1 tracking without paywalls. It covers the basics — injection logging, weight, protein, and side effects — and includes Apple Health sync and data export that other apps charge for. The trade-off is a smaller community and no food analysis features.

Medisafe

Medication reminder app. Medisafe is designed for pill and medication reminders, with some support for injectable medications.

• Medication reminders and scheduling
• Dose tracking
• Refill reminders
• No weight trend analysis
• No food tracking or analysis
• No menstrual cycle tracking
• No GLP-1-specific context

Platform: iPhone, Android · Price: Free with Premium subscription

Medisafe can remind you to take your injection, but it doesn't help you understand what's happening between doses — no weight trends, no symptom correlation, no food guidance. It's a generic medication reminder, not a GLP-1 companion.

Feature-by-feature comparison table

What makes Lumi different from the rest

Every app in this comparison does injection tracking. That's table stakes in 2026. What separates Lumi is everything else — the features that actually help between doses.

Two features in particular stand out:

GLP-1 Food Checker — powered by Apple Foundation Models

Lumi's Food Checker lets you point your camera at any food, drink, snack, or nutrition label and get instant, GLP-1-specific guidance. Instead of just logging calories (like MeAgain) or having no food features at all (like Shotsy), it tells you whether something is a good choice, better in moderation, or worth avoiding on a GLP-1 day.

It flags common concerns for GLP-1 users:

• Sugary drinks and hidden sugars
• Fried and greasy foods that worsen nausea
• Heavy sauces and calorie-dense dressings
• Protein-rich options that help with satiety
• Fiber-friendly foods that support digestion
• Portion sizes relative to reduced appetite

Everything runs on-device through Apple Foundation Models — no photos are uploaded, no data leaves your phone. MeAgain offers photo food logging, but it requires cloud processing and doesn't provide GLP-1-specific guidance.

Shareable Polaroid progress cards

Lumi generates polaroid-style cards from your weight trend chart. MeAgain has Journey Cards for progress photos, but Lumi's polaroid format is specifically designed for celebrating weight milestones — shareable on social media, group chats, or with your healthcare provider.

Frequently asked questions

What is the best app for tracking Ozempic or Wegovy?

Lumi is the most complete GLP-1 tracking app for semaglutide medications like Ozempic and Wegovy. It tracks injections, weight trends, symptoms, menstrual cycles, and food in one app with no subscription. Shotsy is the most popular alternative for injection tracking and weight graphs, but it has no food or nutrition features. MeAgain covers food and symptoms but costs $4.99/week with a hard paywall.

Is there a free GLP-1 tracking app?

Glippy is the only 100% free GLP-1 tracker with no paywall — it includes injection tracking, weight, protein, medication levels, Apple Health sync, and data export. Shotsy has a free tier but locks Apple Health sync and medication level charts behind the subscription. MeAgain has no free features at all. Lumi costs $5.99 one-time with no subscription — less than one week of MeAgain or one month of Shotsy premium.

Which GLP-1 tracker has the best food scanner?

Lumi's GLP-1 Food Checker is the only camera-based food tool designed specifically for GLP-1 users. It uses Apple Foundation Models to analyze food on-device and provides GLP-1-relevant guidance (not just calorie counts). MeAgain offers photo-based food logging with five input methods, but it focuses on calorie and macro tracking rather than GLP-1-specific food recommendations. Shotsy and Glippy have no food analysis features at all.

Do GLP-1 apps track menstrual cycle changes?

Lumi is the only GLP-1 tracker in this comparison that includes menstrual cycle tracking. This matters because semaglutide and tirzepatide can affect cycle timing, flow, and symptoms — something users on GLP-1 subreddits frequently report. Shotsy, MeAgain, Glippy, and Medisafe all require a separate period tracker.

Which app is most private for GLP-1 tracking?

Lumi and Glippy are the most private options. Lumi requires no account, uses no analytics or telemetry, and stores data on-device with optional iCloud sync. Glippy also works without an account. Shotsy has faced privacy scrutiny following their 2025 funding round. MeAgain requires an account and stores data on their servers — they also sell compounded GLP-1 medications in-app, which raises questions about how health data is used.

How does Lumi compare to Shotsy?

Shotsy excels at injection tracking and weight graphing — it's the most polished shot tracker available. But it has zero nutrition features, no food database, no AI food analysis, and no menstrual cycle tracking. Apple Health sync requires a paid subscription. Lumi covers injection tracking plus food analysis, menstrual cycle tracking, symptom logging, and on-device AI — all for a one-time $5.99 with no subscription.

How does Lumi compare to MeAgain?

MeAgain is the most feature-rich competitor with food logging, side effect tracking, and progress photos. However, it requires a hard paywall ($4.99/week or $39.99/year) with no free tier, and it also sells compounded medications in-app. Lumi offers on-device AI food analysis with GLP-1-specific guidance, menstrual cycle tracking, and complete privacy — all for a one-time $5.99 payment with no account required.

What is the cheapest GLP-1 tracker app?

Glippy is completely free (ad-supported). Lumi costs $5.99 one-time with no subscription — making it the cheapest paid GLP-1 tracker with full features. For comparison, Shotsy premium costs $9.99/month ($119.88/year), and MeAgain costs $4.99/week ($259.48/year) or $39.99/year. Over one year, Lumi costs 95% less than Shotsy premium and 98% less than MeAgain's weekly plan.

Which GLP-1 app works on iPad?

Lumi is available on both iPhone and iPad with full feature support and iCloud sync between devices. Shotsy and MeAgain are primarily iPhone apps. Glippy is iPhone only. Medisafe works on iPhone and Android but has no GLP-1-specific features.

Which GLP-1 tracker has the best weight chart?

Lumi and Shotsy both have strong weight trend charts. Shotsy's charts are color-coded by dosage level, which makes it easy to see how weight changed relative to dose changes. Lumi's weight charts include polaroid-style shareable cards for milestones and integrate with menstrual cycle data and food analysis for more complete context. Glippy and MeAgain also track weight but with less visual polish.

Can I use a GLP-1 tracker for compounded semaglutide?

Yes. Lumi, Shotsy, Glippy, and MeAgain all support tracking compounded semaglutide and tirzepatide alongside branded medications like Ozempic, Wegovy, Mounjaro, and Zepbound. Lumi tracks any GLP-1 medication with custom dose amounts. MeAgain also sells compounded GLP-1 medications directly in-app ($129/month for semaglutide), which some users see as a conflict of interest for a tracking app.

Do I need an account to use a GLP-1 tracker?

Lumi and Glippy do not require an account — your data stays on your device with optional iCloud sync (Lumi) or local storage (Glippy). Shotsy works without an account but has no cloud backup, meaning data can be lost when switching devices. MeAgain requires an account to use the app at all, and Medisafe also requires account creation.

Bottom line: which GLP-1 app should you use?

• Best overall for GLP-1 users: Lumi — the only app that combines injection tracking, weight trends, AI food checking, menstrual cycle tracking, symptom logging, and progress sharing in one private, subscription-free app for $5.99.
• Best free GLP-1 tracker: Glippy — 100% free with no paywalls, solid injection tracking, medication level charts, and data export. iOS only.
• Best injection tracker (no food features): Shotsy — the most popular GLP-1 tracker with excellent weight graphs and dose tracking, but no nutrition features and subscription pricing.
• Most comprehensive (with subscription): MeAgain — five food logging methods, 18 side effect presets, and progress photos, but a steep $4.99/week paywall and no free tier.
• Best medication reminder (no GLP-1 context): Medisafe — reliable dose reminders, but no weight trends, food tracking, or GLP-1-specific features.
