# Best GLP-1 Tracker Apps in 2026: What to Look For and How They Compare Source: https://www.trackpep.com/blog/best-glp-1-tracker-apps-2026 > Educational information only. Not medical advice, and not a dosing recommendation. TrackPep records what you enter; it never calculates, converts or decides a dose for you. Talk to a licensed clinician. A fair guide to GLP-1 tracker apps for Ozempic, Wegovy, Mounjaro and Zepbound users: the checklist a good app must meet, plus a comparison of TrackPep, Shotsy, PeptIQ and Regimen. ## Short answer The best GLP-1 tracker is the one that logs your injections with site rotation, charts weight and measurements, records side effects, sends reminders, tracks cost, exports your data and shows no ads. Shotsy suits iPhone users with one GLP-1; TrackPep suits people who want web, iOS and Android plus a private log. Features and prices vary by country. *Last reviewed October 2026. Features and prices vary by country and change often, so confirm everything in your own app store before you pay.* We build one of the apps below, so read this with that in mind. We only state facts we could verify, and where we could not, we say "check the current listing". ## The short answer The best GLP-1 tracker app is the one you will still open in month six. In practice that means it logs a weekly injection in a few taps, remembers which site you used last, charts your weight and measurements, records side effects, reminds you before a dose is due, keeps your costs in one place, lets you export your data, shows no ads, and can produce a summary your clinician can read. Among the apps people compare most in 2026: **Shotsy** is a polished, focused shot logger for iPhone users on a single GLP-1; **Regimen** has the broadest feature set, including lab overlays; **PeptIQ** is an iOS app known for AI vial scanning and on-device storage; and **TrackPep** (ours) runs on web, iOS and Android with a private manual log. None is right for everyone, and the table below shows who each one suits. If you also track research peptides, read our broader [peptide tracker comparison](/blog/best-peptide-tracker-apps-2026). This guide is written for people on GLP-1 medication such as semaglutide (Ozempic, Wegovy) or tirzepatide (Mounjaro, Zepbound). ## What a good GLP-1 tracker must do Feature lists all look alike. This checklist is what actually decides whether a tracker helps over months of therapy. ### 1. Dose and injection log with site rotation notes The core job: record the date, the medication, the amount you and your prescriber settled on, and where you injected. Rotation matters because repeatedly using one spot can irritate skin, so a good app shows your last sites and makes it obvious where you have not injected lately. Our [injection site rotation guide](/blog/peptide-rotation-sites-guide) covers the habit in more detail. The app should record what you tell it. It should not tell you what to take. ### 2. Weight and measurements trend Day-to-day weight is noisy. A useful app charts a smoothed trend and lets you log waist, hip and other measurements, because the scale alone can hide progress. See our guide to [weight tracking on GLP-1](/blog/weight-tracking-on-glp-1) for why trends beat single weigh-ins. ### 3. Side-effect log Nausea, constipation, fatigue and injection site reactions are common, especially while the dose is being stepped up. A log that ties each symptom to a date, severity and the day relative to your injection turns "I felt rough" into something your clinician can act on. We list what to record in [common GLP-1 side effects and how to track them](/blog/glp-1-side-effects-tracker). ### 4. Reminders A reminder for the next injection is the feature most people use daily. Good apps let you set the time, handle a missed or late dose without nagging, and work for medications on different schedules. ### 5. Cost tracking GLP-1 therapy can be a large recurring expense, and prices differ widely by country, insurer and whether you use a brand or a compounded product. Tracking what each pen or vial cost helps you see your real cost per dose over time. We walk through it in [how to track GLP-1 cost per dose](/blog/how-to-track-glp-1-cost-per-dose) and the [GLP-1 cost guide](/blog/glp-1-cost-guide-2026). ### 6. Export and privacy Health logs are sensitive. Ask where the data lives (on your device, or a synced account), whether you can delete your account, and whether you can take your data with you. An app you cannot leave is a risk. ### 7. No ads An app holding your medical history should not be funded by showing you ads or selling your data. Check the privacy section of the store listing for what is collected. ### 8. A clinician-shareable summary The payoff of all this logging is a better appointment. Look for a printable or exportable report with doses, weight trend and side effects in one place. ## The apps compared ### TrackPep Ours. Web, iOS and Android under one account, available in many languages. It is a tracking and logging app: you enter every dose yourself, with injection-site rotation on a visual body map, reminders, weight and measurements, side-effect and hydration logging, and photo or text food logging with a daily AI allowance. Pro adds ten times the AI allowance, unlimited compounds, full history and a printable report with data export. What it does not do: it does not recommend doses, and it has no dose calculators or unit conversion. It is not medical advice. The free plan covers 3 active compounds with 30-day history; Pro is $7.99 per month or $34.99 per year, with no trial. **Choose TrackPep if** you want one private log across phone and browser, or you track a GLP-1 alongside something else. **Choose something else if** you only track one GLP-1 on an iPhone and want the most established single-purpose logger. See the full [TrackPep vs Shotsy](/vs/shotsy) page, plus the [GLP-1 tracker](/glp-1-tracker), [semaglutide tracker](/semaglutide-tracker) and [tirzepatide tracker](/tirzepatide-tracker) pages. ### Shotsy A well-designed tracker focused specifically on GLP-1 medications such as Ozempic, Wegovy, Mounjaro and Zepbound. It is an iOS app with an annual subscription (check the current listing for price). **Choose Shotsy if** you track exactly one GLP-1, use an iPhone, and want a focused shot logger with a large user base. It does that job well and does not try to do more. ### Regimen One of the most feature-complete multi-compound trackers, with a large compound library and advanced lab and biomarker overlays. It runs on web and mobile, with a free tier plus a subscription. See [TrackPep vs Regimen](/vs/regimen). **Choose Regimen if** you want the deepest feature set and do not mind extra complexity to get it. ### PeptIQ An iOS app known for AI-assisted vial scanning and on-device data storage, with injection-site logging. It is freemium. See [TrackPep vs PeptIQ](/vs/peptiq). **Choose PeptIQ if** you want AI scanning and are happy keeping everything on one iPhone. On-device storage is a genuine privacy advantage if that is your priority. ### Others Shotlee, PepTracker and others also appear in app-store results. Coverage and pricing change often, so judge them against the checklist above rather than any roundup, including this one. ## Comparison table | | Platforms | Focus | Free tier | Export or report | Best for | |---|---|---|---|---|---| | TrackPep | Web, iOS, Android | GLP-1 and other compounds | Yes: 3 compounds, 30-day history | Printable report and export (Pro) | One private log across devices | | Shotsy | iOS | GLP-1 only | Check current listing | Check current listing | One GLP-1 on iPhone | | Regimen | Web, mobile | Large compound library | Yes, plus subscription | Check current listing | Widest feature set | | PeptIQ | iOS | Multi-compound | Freemium | Check current listing | AI vial scanning, on-device data | "Check current listing" means we could not verify a durable fact and do not want to guess. Pricing and features are as of October 2026. ## How to choose 1. **Which phone and which computer?** If you want to review your log on a laptop, iOS-only apps are out. 2. **One medication or several?** A GLP-1-only app is simpler if that is all you take. 3. **Where should the data live?** On-device storage and a synced account are different trade-offs, and neither is universally correct. 4. **What will you actually use?** Reminders, a weight chart and a side-effect log cover most of the benefit. Start free, and pay only once you hit a limit that matters. ## Questions to ask before you subscribe Before paying for any app, spend ten minutes on the free tier and answer these: - **How many taps does a logged injection take?** If it takes more than a few, you will stop logging on busy weeks. - **Can I fix a mistake?** Everyone mis-taps a date or a site. Editing and deleting entries should be easy. - **What happens to my history if I stop paying?** Some apps lock older entries; others keep them readable. Free tiers often limit how far back you can see. - **Will it work when I switch medication?** People move from one GLP-1 to another, pause, or change prescriber. Your log should survive that without starting over. - **Is the support real?** A quick message to the developer before you subscribe tells you how problems will be handled. If you are weighing cost, remember that the app is a small line next to the price of the medication itself. Our [GLP-1 cost guide](/blog/glp-1-cost-guide-2026) shows how to think about the larger numbers. ## What no tracker should do Be wary of any app that tells you how much to inject or when to increase. Titration is your prescriber's call, based on how you respond. A tracker records; it does not prescribe. This matters for compounded products too, where quality varies; see [what to check with compounded semaglutide](/blog/is-compounded-semaglutide-safe-what-to-check). ## FAQ **Which is best for Ozempic?** Any app on the checklist works for semaglutide. Shotsy suits iPhone-only users, TrackPep suits multi-device users. **Which is best for Mounjaro or Zepbound?** The same logic applies to tirzepatide; the medication matters less than platform, price and privacy. **Is my data safe?** It depends on the app. Read the store privacy label and look for account deletion and export. ## Bottom line Pick the app that fits your phone, your medication count and your privacy comfort, and run the checklist before you pay. Most people do well on a free tier first. ## Frequently asked questions ### What is the best app to track Ozempic or Mounjaro injections? There is no single best app. Shotsy is a focused iPhone shot logger for one GLP-1, TrackPep covers web, iOS and Android with a private manual log, and Regimen has the widest feature set. Pick by platform, how many compounds you track and how much you want to pay. ### Are GLP-1 tracker apps free? Several have a free tier. TrackPep's free plan covers up to 3 active compounds with 30-day history, and Pro is $7.99 per month or $34.99 per year. Other apps use subscriptions or freemium models that change often, so check each current store listing in your country. ### Can a GLP-1 app tell me what dose to take? It should not. A tracking app records what you and your prescriber decided; it does not set or adjust doses. TrackPep is tracking and logging only, with no dosing advice and no calculators. Dosing decisions belong with your clinician. ### Can I share my GLP-1 log with my doctor? Yes, if the app can export or print a summary. Look for a clean report of doses, weight trend and side effects you can bring to an appointment. TrackPep Pro includes a printable report and data export. ## Sources - [Mounjaro (tirzepatide) official site, Eli Lilly](https://www.mounjaro.com/) - [Ozempic (semaglutide) official site, Novo Nordisk](https://www.ozempic.com/) - [FDA warns 30 telehealth companies against illegal marketing of compounded GLP-1s](https://www.fda.gov/news-events/press-announcements/fda-warns-30-telehealth-companies-against-illegal-marketing-compounded-glp-1s) By TrackPep Team.
