Best GLP-1 Tracker Apps in 2026: 8 Apps Compared (Free & Paid)

A weekly GLP-1 shot sounds easy to track until you're three weeks in and can't remember which side got last Tuesday's injection or when the current pen runs out. A notes app gets most people through month one. After that, they go looking for something built for the job.

We looked at eight: StackLogR, Shotsy, MeAgain, Glapp, Pep, PeptIQ, Shot Pal, and GlowBack. One is ours — StackLogR — so read that section knowing who wrote it. It isn't in a store yet, and we say so plainly. For a shorter rundown of GLP-1 tracking on StackLogR specifically, see /glp-1-tracker/; this article is the full category comparison.

Last verified August 9, 2026, against live App Store and Google Play listings. Pricing and store details change — re-check before relying on any number here if you're reading this months later.

Quick answer

For GLP-1-only tracking with the most reviews behind it, Shotsy is the pick — nearly 29,000 App Store ratings, purpose-built, free to start. StackLogR is the pick for the simplest, most private log, or for a GLP-1 alongside peptides, TRT, or HRT on one on-device schedule — free, but pre-launch with no review history. MeAgain goes deepest on food and nutrition logging tied to dose days. Glapp has a generous free tier plus real supply tracking. Pep is plain on both platforms, though its label carries the heaviest ad-tracking here. PeptIQ suits AI-assisted entry and treats GLP-1s as a first-tier compound. Shot Pal is iPhone-only with dedicated weight/BMI charts. GlowBack covers the widest medication list but has the smallest review sample and most privacy flags.

At-a-glance comparison

The privacy column is where the real split shows up — not always in the direction the marketing suggests. This sweep found three real mismatches between a listing's claims and its own privacy label, which is why “read the actual label” is a criterion below.

How we evaluated

We didn't score on feature count — a tracker with forty features you never open is worse than one with ten you use. In order:

1. Time to log a dose — the biggest predictor of whether you're still using it in week six.
2. Privacy label vs. marketing — does the label actually match the site's claims? Not always.
3. Price transparency — is the real price published and consistent, or does it vary by listing?
4. Reminder reliability — does it nudge you on the right day without babysitting settings?
5. Weight tracking — is there a real place to log weight, or is that left to another app?

The apps, reviewed

1. StackLogR

We built StackLogR because a GLP-1 shot rarely happens in isolation — a lot of people running one are also on a peptide, TRT, or HRT protocol, and most trackers force that across two apps.

Pricing/platforms: iOS and Android at launch. Free during early access.

Best for: A GLP-1 shot logged on the same on-device schedule as everything else, with no account.

Strengths: Fully on-device on both iOS and Android — no account, no login, no cloud sync. One-tap dose logging with a morning-to-night day view; local reminders for dose day, cycle timing, low stock, and vial expiry; vial and sealed-stock inventory with beyond-use-date awareness; injection-site rotation suggestions; a 100+ compound guide with zero dose amounts by policy.

Trade-offs: Pre-launch — no store listing or reviews yet; early access by waitlist at stacklogr.com. Built as a general injectable tracker, not a GLP-1 specialist — no food or nutrition logging, and weight tracking is a simple log with a trend line and BMI rather than a full body-metrics suite.

Verdict: StackLogR is the only peptide tracker that's fully on-device on both iOS and Android — free, with no account. Worth the waitlist if a GLP-1 is one piece of a bigger protocol and privacy matters more than a mature feature set.

2. Shotsy

Pricing/platforms: iOS and Android. Free with a usable basic tier; subscriptions run $9.99–$19.99/month or $39.99–$59.99/year. iOS: 4.8★ (~29,000 ratings). Android: 100K+ downloads, 4.7★ (~9,560 reviews).

Best for: Tracking a GLP-1 exclusively (Ozempic, Wegovy, Zepbound, Mounjaro) with the most established app in the category.

Strengths: Purpose-built GLP-1 dosing schedules, weight and side-effect tracking, a polished mature interface. On iOS, privacy is strong: local data synced only through your own private iCloud, no account, label reads “Data Linked to You: None.”

Trade-offs: Doesn't track peptides at all. Privacy splits by platform: Android uses Google Sign-In and Firebase, with a data-safety disclosure of possible third-party sharing.

Verdict: The safe default for GLP-1-only tracking with the deepest track record here. Deciding between it and a broader logger? See our head-to-head against StackLogR.

3. MeAgain

Pricing/platforms: iOS 15.1+ and Android. Free with in-app purchases; iOS subscription tiers span $14.99–$119.99 across weekly/monthly/annual options, no one-time purchase listed. iOS: 4.8★ (~28,000 ratings). Android: 4.6★ (~2,010 reviews, 50K+ downloads).

Best for: Food and nutrition logging built into the same app as your GLP-1 dose log.

Strengths: Tracks injectable shots and oral GLP-1 medications in one app; protein, fiber, and water logging tied to dose days; side-effect journal, progress photos, home-screen widget.

Trade-offs: The iOS privacy label is the most extensive here — health data, purchase history, contact info, user content, search history, usage data, sensitive info, all linked to identity (Android declares no third-party sharing). MeAgain's “#1 GLP-1 app of 2026” claim traces to a self-published press release — treat it as marketing.

Verdict: If nutrition logging matters as much as the shot, MeAgain goes further than most apps here — read the privacy label before handing over that much linked data.

4. Glapp

Pricing/platforms: iOS 17+ (also Watch, Mac), Android, web. Free with in-app purchases; Glapp Max runs $4.99/week, $9.99/month, $39.99/year. iOS: 4.7★ (790 ratings). Android: 4.5★ (336 ratings, 10K+ downloads).

Best for: A generous free tier plus real inventory/supply tracking.

Strengths: Schedule support that follows a changing dosing schedule over time (a feature note, not guidance on what a schedule should be); injection-site rotation; supply tracking with auto-deduction; a research-citing “Wisdom” feature; provider progress reports.

Trade-offs: The marketing site calls the app “completely free” and says it “doesn't monetize user data,” but both store listings show a Max paywall behind some features. The iOS privacy label lists health data, contact info, identifiers, and usage analytics; requires a cloud account, no on-device option.

Verdict: Capable and generously free, with real inventory features — just weigh the site's privacy language against the actual label.

5. Pep

Pricing/platforms: iOS and Android (from Shred Apps LLC; Android live since 2024). Free with in-app purchases; $9.99/month or $39.99/year. iOS: 4.7★ (853 ratings).

Best for: A plain tracker on both iOS and Android if you can live with a heavier ad-tracking label.

Strengths: Native, maintained apps on both platforms, a solid iOS review base, straightforward pricing.

Trade-offs: The iOS privacy label discloses the heaviest ad-tracking footprint in this comparison — identifiers and contact info, plus cross-app and cross-site tracking for marketing and personalization. Feature detail beyond pricing and the label isn't well documented.

Verdict: Priced in line with the rest of this list, but the privacy label is the one to read most carefully — the cross-app tracking disclosure is the heaviest here.

6. PeptIQ

Pricing/platforms: iOS, Android, and web. Freemium — free tier includes basic logging and calculators; premium runs $9.99/week, $19.99/month, or $49.99–$99/year, the priciest premium in this comparison.

Best for: Running a GLP-1 alongside other compounds and wanting a genuine power tool, not a bare logger.

Strengths: Markets semaglutide, tirzepatide, and retatrutide as a first-tier category; an AI vial scanner (premium) and a research chatbot grounded in your own history, with source links; dosing/unit-conversion calculators; inventory tracking with refill and expiration alerts; wearable integrations (Apple Health, Google Fit, Whoop, Oura).

Trade-offs: The most expensive premium tier here, up to $99/year. Cloud-synced and account-based — the AI features need your data on their servers.

Verdict: If you want GLP-1s treated as seriously as any other compound, and cloud sync doesn't bother you, PeptIQ is the most capable option here — at the highest price.

7. Shot Pal

Pricing/platforms: iOS only (16+; also iPad, Mac, Vision) — confirmed not on Google Play. Free with in-app purchases; Pro runs roughly $5.99–$6.99/week, $7.99/month, or from about $12.49/year (a wide range on the listing, worth confirming in-app), plus a $39.99 lifetime option. Rated 4.6★ (263 ratings).

Best for: iPhone users who want dedicated weight and BMI charts alongside their GLP-1 log.

Strengths: Built around semaglutide/tirzepatide tracking with weight/BMI charts, diabetes-adjacent tools, and reminders. A lighter privacy footprint than several apps here — usage data (may track across other apps), diagnostics, and infrequent medical-treatment info.

Trade-offs: iOS only, confirmed not on Google Play. Public records on the developer are inconsistent, so we're not naming one here.

Verdict: A lighter-privacy, iPhone-only option with real weight/BMI tracking — worth a look on iOS, off the table otherwise.

8. GlowBack

Pricing/platforms: iOS 15.6+ and Android. Free with in-app purchases; the iOS listing shows subscription pricing inconsistently — two different monthly/annual price pairs on the same listing, so we're not printing an exact number. iOS: 4.6★ (17 ratings). Android: 4.4★ (86 ratings, 1K+ downloads).

Best for: A wider medication list and a photo timeline, if you can accept the privacy trade-offs.

Strengths: 30+ medications, including compounded and oral options; a next-dose dashboard, level trend charts, a photo timeline, and widgets.

Trade-offs: The iOS label discloses device ID used for third-party advertising. Android's data-safety section self-declares “no data collected” while also stating “data can't be deleted” — worth flagging. Review samples are tiny, and the publisher, Meta Innovation Limited (Hong Kong), also ships sticker-trading and puzzle apps.

Verdict: The broadest medication coverage here, but the thinnest review base and the most privacy flags — read the label carefully.

The clone flood — and how to pick a serious tracker out of it

Search “GLP-1 tracker” on Google Play and you'll find a lot more than the eight apps above. The related-apps rail alone surfaces 25+ near-identical listings — names like Shotwise, Glippy, GLPeak, Peptio, and Dosely, with icons and descriptions that look template-generated. We didn't review or rank any individually — there isn't enough verifiable information on most listings to say anything trustworthy.

Three checks work on any GLP-1 tracker, not just the ones above:

1. Read the actual privacy label, not the marketing copy. Phaze claims “no cloud, data never leaves your device” — but its own App Store label discloses a user/device ID linked to identity for analytics, plus coarse location. Both are true at once.
2. Check the developer's other apps. GlowBack's publisher also makes sticker-trading, puzzle, and music apps.
3. Compare review counts to marketing claims. MeAgain's “#1 GLP-1 app of 2026” traces to a self-published press release, not an independent ranking.

Small review counts aren't automatically a red flag. DoneDose, an iOS-only indie, sits at just 5 ratings — but its “no accounts, no cloud” claim largely matches its own privacy label, and it includes a visual body-map for site rotation. Small and new isn't the problem; a label that contradicts the pitch is.

FAQ

What is the best GLP-1 tracker app in 2026?

Depends what you value. Shotsy is the most established GLP-1-only option, with the deepest review base here. StackLogR is the pick for privacy and for GLP-1s alongside other compounds — on-device, free, no account — though pre-launch with no review history.

Is there a free GLP-1 tracker app?

Yes. StackLogR is free during early access with no paid tier. Every other app here offers a usable free tier too, though each caps something before a paywall shows up.

Which GLP-1 tracker works on Android?

Everything here has a native Android app except Shot Pal, which is confirmed iOS-only.

Can I track peptides and a GLP-1 in the same app?

Yes. StackLogR, Glapp, and PeptIQ all handle both. Shotsy is the exception here — GLP-1 only, no peptides.

Do GLP-1 tracker apps need an account?

Most do, to sync to a server for backup or cross-device access. Shotsy's iOS app is a partial exception — local storage through your own private iCloud, no account — though Android requires Google Sign-In. StackLogR is the only app here fully on-device with no account on both platforms.

How do GLP-1 tracker reminders work?

They run on your phone's notification system, on a schedule you set in the app. If the weekly cadence itself trips you up, our guide on remembering a weekly shot covers the pattern, independent of which app you use.

Do GLP-1 tracker apps track weight?

Some do. Shotsy and Shot Pal both include dedicated weight tracking, and Shot Pal adds BMI charts. MeAgain logs progress photos rather than a weight number. StackLogR includes an optional weight log with a trend line, goal weight, and a BMI gauge alongside its daily check-ins.

Why are there so many nearly identical “GLP-1 Tracker” apps on the Play Store?

Google Play's related-apps rail surfaces 25+ near-identical listings, names like Shotwise, Glippy, GLPeak, Peptio, and Dosely. We don't review unverified clones — read the actual privacy label, check what else the developer publishes, and compare its review count to whatever it claims.

What's the easiest GLP-1 tracker for beginners?

Shotsy and StackLogR both need only a few steps to log a dose. Shotsy has the longer track record and bigger review base; StackLogR is simpler in scope and on-device, though newer.
