The Best GLP-1 Tracker Apps in 2026, Compared
The best GLP-1 tracker apps of 2026, side by side: Pep, Shotsy, MeAgain, Glapp and GlucoPal. Ratings, prices, what is free in each, Android support, languages and features, checked against each app’s own store listing, including where a rival beats Pep.
Written by Andrew Bentley, founder of Shred Apps, the studio that makes Pep. App Store listings and developer sites re-checked October 12, 2026.
The best GLP-1 tracker apps in 2026: the short answer
Pep is the best GLP-1 tracker app for most people: free core tracking for shots and pills, injection-site rotation, progress photos, body measurements, GLP-1 nutrition with barcode scanning, and a medication-level indicator, on iPhone and Android in 10 languages, with free web calculators alongside. Shotsy is the most established alternative but has no food log (you enter daily totals by hand), charges for its level chart and Apple Health sync, and does not list progress photos. MeAgain is English-only with a Premium paywall. Glapp is injection-only and the newest of the group. GlucoPal is iPhone-only.
Pep is not Pep AI. Pep GLP-1 Tracker is the iPhone and Android app from Shred Apps for logging GLP-1 shots or pills, reminders, weight, food, side effects, and progress. It is free to download with an optional Pro subscription, and it is separate from Pep AI, the peptide-focused app that some 2026 roundups confuse it with (details further down).

The best free GLP-1 tracker apps: what you get for $0
All five of the best GLP-1 tracker apps are free to download, but “free” means different things once you open them. Some keep the whole routine free. Others let you log a dose, then ask for a subscription when you want the level chart, the Health sync or the extras. Here is where each app draws that line, based on its own store listing.
| App | Free to download | What costs extra | Worth knowing |
|---|---|---|---|
| Pep | iPhone and Android | Optional Pro (about $40/yr) for AI photo food scanning and other extras; core tracking never requires it | Medication-level indicator, progress photos, body measurements and barcode food logging are free; no account required |
| Shotsy | iPhone and Android | Shotsy+ (yearly plans listed from $39.99) for the medication-level chart and Apple Health sync | No food log or progress photos listed; its site says pill tracking is available on iOS |
| MeAgain | iPhone and Android | MeAgain Premium (in-app purchases listed from $14.99 to $119.99) for full features, including its widget and chat companion | English only; the free tier is narrower than Pep’s |
| Glapp | iPhone, Android and web | Glapp Max, an optional paid tier | Level chart is free, but it tracks injections only and requires an account |
| GlucoPal | iPhone only | GlucoPal Pro (yearly plan listed at $29.99) for the medication-level forecast and PDF report | No Android app |
Free and paid tiers as listed on each app’s App Store page or developer site, re-checked October 12, 2026. Subscription prices and tiers change, so check the listing before you subscribe.
- Best free GLP-1 tracker app overall: Pep. Shots, pills, reminders, site rotation, weight, side effects and the medication-level indicator all stay free.
- Best free GLP-1 app for iPhone: Pep, which syncs with Apple Health and keeps progress photos and barcode food logging free. GlucoPal is the iPhone-only alternative if you do not mind paying for the level chart.
- Best free GLP-1 tracker for Android: Pep, Shotsy, MeAgain and Glapp are all on Google Play. Pep is the one that keeps the level indicator, photos and food logging free there too; see the GLP-1 tracker app for Android guide.
- Best free option if you take a daily pill: Pep. Glapp lists injections only, and the other three put part of the routine behind a subscription.

One more check before you settle on any free health app: read how it handles your data. The FTC’s guide, Does your health app protect your sensitive info?, suggests comparing privacy notices and reviewing each app’s sharing settings, which matters when you are logging medication and weight.

The five apps, one by one
1. Pep — best free all-round GLP-1 tracker
4.7 App Store (1,000+) · 4.7 Google Play (2,000+) · Free, Pro about $40/yr · iPhone, iPad, Android · 10 languages
Pros
- Core tracking is free: shots, pills, reminders, rotation, weight and side effects
- Medication-level indicator and progress photos without a subscription
- GLP-1 nutrition with protein, fiber and water, plus free barcode scanning and food search (AI photo scanning on Pro)
- Same app on Android, in 10 languages; free web calculators for cost, dose schedule, weight loss, protein and missed doses
- Body measurements and a daily summary alongside weight, photos and side effects
- No account required to start, and Pro (about $40/yr) is optional
Cons
- No home-screen next-dose widget or Apple Watch app yet
- No PDF report to share with your doctor
- 10 languages, fewer than Shotsy’s 17
- AI photo food scanning needs Pro; barcode scanning and food search are free
Bottom line: if you want the full routine tracked for free on either platform, start here. If a widget, an Apple Watch app or a PDF report matters most, look at Glapp, Shotsy or GlucoPal Pro instead.
Everything Pep does · App Store · Google Play
2. Shotsy — best for multiple medications and languages
4.8 App Store (30,000+) · 4.7 Google Play (11,000+) · Free, premium subscription · iPhone, iPad, Android
Pros
- Clean one-tap dose logging with reminders and a next-dose countdown
- Its site says core features (dose and side-effect tracking, weight charts, nutrition logging) are free
- Large, established review base
- Apple Health import (Shotsy+); on iPhone and Android, 17 languages
Cons
- Medication-level chart and Apple Health sync sit behind the Shotsy+ subscription (yearly plans listed from $39.99)
- No food log: you type in daily protein, water and calorie totals or import them from a separate calorie app (its listing suggests MyFitnessPal or Lose It)
- No progress photos listed
- No free web calculators
Bottom line: the most established tracker, but there is no food log, you pay for the level chart, and you go without progress photos. Pep gives you all of those free.
3. MeAgain — best for food-first tracking
4.8 App Store (37,000+) · 4.6 Google Play (2,600+) · Free tier, subscription for full features · iPhone, iPad, Android · English only
Pros
- Food logging by barcode and search, with protein, fiber and water goals
- Side-effect journal, progress photos and weight trends
- Widgets, medication-level context between doses, Apple Health sync
Cons
- English only
- Full features require a Premium subscription; the free tier is narrower than Pep’s
- No body measurements or free web calculators
Bottom line: a polished companion with a paywall around the extras and no language options. Pep covers the same routine free, in 10 languages.
4. Glapp — injection-only newcomer
4.7 App Store (900+) · 4.5 Google Play (390+) · Free, optional upgrade · iPhone, iPad, Android · English only
Pros
- Medication-level estimate between doses
- Logs compounded doses
- Daily check-in for cravings, mood, energy and sleep
- Free medication-level chart, home-screen widgets and an Apple Watch app
- Also runs on the web, with a vial tracker for compounded doses
Cons
- No pill tracking listed; built around injections only
- Extras sit in a paid tier called Glapp Max
- Nutrition is coaching tips rather than a food log; no progress photos or body measurements listed; account required
- Newest app in the group (March 2026) with the smallest review base; English only
Bottom line: an injection-only tracker with a narrow feature set. Skip it if you take a daily pill or want a food diary and progress photos; Pep includes all of them free.
5. GlucoPal — best iPhone-only option
4.8 App Store (3,000+) · Free, Pro subscription · iPhone, iPad · 6 languages per developer · listed on the App Store as “Zepbound & Mounjaro Tracker”
Pros
- Injection-site rotation, titration steps and dose history with reminders
- Apple Health sync, progress photos, barcode and photo food logging
- No account required
Cons
- No Android app
- No body measurements listed
- Medication-level chart and PDF report require GlucoPal Pro; no free web calculators
Bottom line: a capable iPhone-only tracker, but Android users are out, the level chart is paid, and there are no free calculators. Pep does the same job on both platforms.
Best GLP-1 tracker apps for iPhone vs Android
Four of the five apps run on both platforms, but they are not identical on each. If you are choosing by phone, these are the differences that show up in the listings.
| App | iPhone | Android | What differs |
|---|---|---|---|
| Pep | ✓ iPhone and iPad | ✓ | Same core tracking on both. Apple Health sync is on iPhone; the Android app does not sync with Health Connect |
| Shotsy | ✓ listing requires iOS 18 or later | ✓ | Its site says pill tracking is available on iOS. Apple Health import is part of Shotsy+ |
| MeAgain | ✓ iOS 16.4 or later | ✓ | English only on both |
| Glapp | ✓ iOS 17 or later | ✓ | Also has a web version; injections only on every platform |
| GlucoPal | ✓ iOS 15 or later | — | No Android app |
iOS requirements from each App Store listing, October 12, 2026. Android availability from Google Play and each developer’s site.
- On iPhone: all five work, so the choice comes down to what is free and what you want to log. Check the iOS requirement first if your phone is a few years old, and decide whether Apple Health sync matters to you, because not every app includes it free.
- On Android: your options are Pep, Shotsy, MeAgain and Glapp. If you take a daily pill, confirm pill support in the Android version before you commit. Dose reminders on Android also depend on notification and battery settings, which the Android guide linked above walks through.
- If you might switch phones: pick an app that exists on both platforms, so a new phone does not force you to start a new history.
How we picked the best GLP-1 tracker apps
First, the disclosure: we make Pep, so we are not a neutral reviewer. To keep this comparison checkable, every claim about another app comes from that app’s own store listing or website, and where another app offers something Pep does not, such as a home-screen widget, the tables say so.
Which apps made the list. We included apps built specifically for GLP-1 medications that are live on the App Store or Google Play and have enough public ratings to judge. General calorie counters that added a dose log are covered separately in the head-to-head pages linked below.
What we compared. Five things decide whether a tracker fits a GLP-1 routine:
- Medication coverage: weekly shots, daily pills, or both.
- What is free: which features work without a subscription, and what the paid tier costs.
- Platforms and languages: iPhone, Android, and how many languages the listing shows.
- Tracking depth: site rotation, a medication-level estimate, food, photos, measurements and side effects.
- Track record: store rating and how many people have rated it.
Where the facts come from. Ratings, review counts, price tiers, language counts and platforms were read from each app’s public App Store and Google Play listing, with feature claims taken from the developer’s own store description or website. This is a listing-based comparison, not a lab test: a feature marked — was not listed; the app may still offer it. The tables were first compiled in September 2026, and the App Store listings and developer sites were re-checked on October 12, 2026. Review counts move daily, so treat them as a snapshot. If you spot something out of date, use the contact link and we will refresh the table.
A note on “Pep” in other roundups
Several 2026 comparison pages, including Shotsy’s, describe Pep as a paid peptide app with a reconstitution calculator, a 75-compound library, an Apple Watch app and a $3.99-per-week subscription. Those details belong to Pep AI: GLP-1 Peptide Tracker (earlier listed as Pep AI: Peptide GLP-1 Tracker), a different app from a different company, Zode Development LLC, that launched in February 2026. Pep GLP-1 Tracker (on the App Store since 2024) is free to download, tracks GLP-1 medications rather than research peptides, is rated 13+, and is available in 10 languages on iPhone and Android. The Pep facts page has the full details.
Which one should you download?
- You want it free and complete, on iPhone or Android: Pep.
- You take shots and pills, or might switch: Pep. Weekly shots and daily pills share one log on iPhone and Android, with the level indicator free for both. MeAgain also lists pill tracking; Shotsy’s site says its pill tracking is on iOS, and Glapp is injection-only.
- Food and appetite are the hard part: Pep gives you barcode scanning, food search and protein, fiber and water goals without a subscription, with an AI photo scanner on Pro.
- You want to see progress beyond the scale: Pep, the only app here with progress photos, body measurements and a daily summary together.
- You want a home-screen widget or next-dose countdown: Shotsy, MeAgain and Glapp list one. Pep does not list one.
- You want a PDF report to bring to appointments: Shotsy, or GlucoPal Pro on iPhone. Pep does not export one yet.
- You want an Apple Watch app: Glapp lists one. Pep does not have one yet.
- You want the app in a language Pep does not cover: Shotsy, which lists 17 languages to Pep’s 10.
- You already pay for Shotsy+, MeAgain Premium or GlucoPal Pro and like it: stay, but know that Pep does the same routine free.
- You mainly want calorie counting: MyFitnessPal (free GLP-1 Support) or Lose It! (Premium-only GLP-1 mode) now log doses, but neither matches a dedicated tracker on reminders, rotation and GLP-1 side effects; see Pep vs MyFitnessPal and Pep vs Lose It!.
On a specific medication? Pep has dedicated pages for Ozempic, Wegovy, Mounjaro, Zepbound, tirzepatide and compounded GLP-1s, and a separate roundup of the best Ozempic tracker apps.

Pep is free to download on iPhone and Android, and core tracking stays free: shots and pills, reminders, the medication-level indicator, injection-site rotation, side effects, weight, measurements, progress photos, and barcode food logging. Pep Pro (about $40 a year) is optional and adds extras like AI photo food scanning.
Pep. It logs weekly Wegovy shots and the daily Wegovy pill, reminds you on dose day, shows roughly how much semaglutide is active between doses, syncs with Apple Health, and keeps weight, food, side effects, and progress photos in one free app. See the Wegovy tracker page for details.
Pep, if you want food logging in the same app as your doses: barcode scanning, food search, and protein, fiber, and water goals are free, with an AI photo scanner on Pro.

Pep is our pick, because dose logging for shots and pills, reminders, the medication-level indicator, progress photos and barcode food logging all work without a subscription on iPhone and Android. If you only inject and want a free level chart with a home-screen widget, Glapp is a reasonable alternative.
Check five things: whether it supports your medication form (shots, pills or both), whether it runs on your phone, which features are free, whether it logs food and side effects as well as doses, and how it handles your data. Then try the free version for a week before paying for anything.
