Best GLP-1 Tracker App in 2026:7 Free & Paid Apps for Ozempic, Wegovy, Mounjaro & Zepbound
Updated September 13, 2026
Quick answer
Regimen is the most complete GLP-1 tracker: dose logging, custom scheduling with dose titration, free medication-level charts, injection site rotation, supply tracking, side effects and 50+ daily markers, weight and health metrics, bloodwork, progress photos, and pattern detection across all of it. Free for one medication, on iPhone and Android. Shotsy has been around the longest and has food logging. MeAgain is the simplest app to start with.
We compared the GLP-1 tracking apps people actually recommend, on the things that matter when you're on a GLP-1 for weight loss: never missing your shot, rotating injection sites, watching the weight come off, and making sense of side effects as you titrate up. Here's the honest breakdown.
For most people on a GLP-1, Regimen is the pick: free for one medication, the full list above, and the one tracker that connects your dose to your side effects, weight and labs over time. If you want built-in food logging, Shotsy has it.
The best free GLP-1 tracker app in 2026 is Regimen; Shotsy has been around the longest; Glapp is the standalone medication-level chart.

Methodology
How we compared these apps
We evaluated each app on the things that actually matter on a GLP-1 shot: weekly dose reminders, injection-site rotation, weight-loss and progress-photo tracking, side-effect logging tied to the dose, and - where the app supports it - the estimated medication-level curve. We reinstalled and re-checked the native apps we could install in June 2026; DoseDiary (web-only) and the iOS-only apps we don't run daily are described as "compared," not "tested," because we haven't lived in them.
Regimen is our own app. We rank it #1 on this list because the free tier genuinely covers what a GLP-1 user needs, including the medication-level curve. Other apps' entries reflect their public listings as of the update date above.

The 7 best GLP-1 tracker apps in 2026
1
Regimen
Regimen is a full-featured GLP-1 tracker, free for one medication. It holds the titration plan your prescriber set and steps you up on schedule, shows how much semaglutide or tirzepatide is in your system between shots, and puts your side effects, weight and bloodwork on the same timeline as your doses, so you can see what the medication is actually doing, not just that you took it.
Holly, switched from Shotsy, August 2026: "I'm split-dosing and wanted a program that would allow me to enter specific days for dosing, which Shotsy doesn't do, so I asked Google AI to compare other programs, reviewed Glapp and Regimen and MeAgain, and it looks like Regimen does what I want."
Best for: anyone who wants to see what's actually working on their GLP-1, not just log the shot.
From our own data: Weight is the most-tracked metric on Regimen, logged by roughly four in five users.
Platforms
iOS + Android + web
Price
Free for tracking one medication, plus a 14-day trial. Premium only if you later track more than one.
+
Strengths: - Titration that runs itself. Enter the plan, 2.5 mg for four weeks, then 5 mg, then 7.5 mg, and every dose lands on the right day with a reminder that says how much to take.
−
Limitations: no food, protein or water logging; asks a little more of you than a bare shot log, which is what powers the pattern detection.
Best for: anyone who wants to see what's actually working on their GLP-1, not just log the shot.
Strengths:
Titration that runs itself. Enter the plan, 2.5 mg for four weeks, then 5 mg, then 7.5 mg, and every dose lands on the right day with a reminder that says how much to take.
Any schedule your prescriber set. Weekly on a named day, a split week with two shots about 3.5 days apart, every X days, microdoses at any amount, or a daily pill if you're on an oral GLP-1.
Medication-level chart, free. See where your semaglutide or tirzepatide level sits between shots, which is what's behind a mid-week energy dip or hunger creeping back on day 5 or 6.
Side effects and 50+ daily markers. Nausea, constipation, food noise, appetite, energy, sleep, bloating, heartburn, injection-site reaction and water retention, each with a level and a date next to the dose, so you can tell a settling week from a dose you can't stay on.
Weight and health metrics, with photos. Weight, body fat, resting heart rate, blood pressure and sleep flow in from Apple Health or Health Connect, side-by-side progress photos sit on the same timeline, and your weight trajectory plots against published clinical-trial averages.
Injection site rotation that adapts to you. Suggests the next spot, lets you add your own beyond abdomen, thigh and arm, and rests a sore spot until you say otherwise.
Supply tracking. Pens and vials, doses left and beyond-use dates, so you know when to reorder.
Bloodwork on the dose timeline. Scan the report or type it in; fasting glucose, lipids and the rest of your panel plot against your dose history, so you can see whether a step-up moved a number.
Pattern detection. Watches your doses, markers, weight and labs and tells you what it finds, measured against your own baseline: your food noise tends to creep back around day 5, or your energy dips as the dose wears off. Honest pattern detection, not an AI guessing.
Share-with-provider report. A formatted PDF of your doses, side effects, weight and labs for your next appointment.
Free for one medication. Most features included: the medication-level chart, side effects and markers, bloodwork, health sync, injection site rotation and pattern detection. Premium only if you track more than one medication. Imports your history from another app so you don't start over.
Limitations: no food, protein or water logging; asks a little more of you than a bare shot log, which is what powers the pattern detection.
Verdict: The whole GLP-1 picture in one app: titration, the medication-level chart, side effects, weight, bloodwork and the patterns between them, free for one medication. Learn more about the Regimen app, or go straight to the free GLP-1 tracker.

Shotsy has been around longer than any other GLP-1 tracker and is a polished app. The free tier covers dose logging, injection-site rotation, weight, side effects, and built-in food, protein, and water tracking (something Regimen doesn't have). If a GLP-1 is all you'll ever track and you want the one with the biggest review base, it's a reasonable pick.
Platforms
iOS + Android
Price
Free tier; Shotsy+ runs $9.99 to $19.99/mo or $39.99 to $59.99/yr depending on tier
+
Strengths: Medication-level charts; built-in nutrition (calories, protein, water); polish and community scale.
−
Limitations: one of the pricier tiers on this list; the medication-level chart most GLP-1 users want is on the premium tier; several recent App Store reviews mention features moving to premium over time.
Best for: people who want the GLP-1 app that has been around the longest, with food logging in the same app.
3
Glapp
A GLP-1 tracker on iOS, Android, and web with a free tier, built around pharmacokinetic visualization: estimated medication levels over time based on your dose and timing, and a comparison against published GLP-1 clinical studies. Also tracks "food noise" - the GLP-1 community's term for intrusive food thoughts.
Platforms
iOS, Android, and web (App Store · Google Play)
Price
Free; Max $9.99/mo or $39.99/yr
+
Strengths: estimated medication-level view on the free tier; clean comparison against clinical-trial data; side-effect and injection-site rotation tracking; Apple Health.
−
Limitations: lighter on day-to-day tracking (bloodwork, multi-compound) than a full-featured app.
Best for: anyone who mainly wants the medication-level chart.
4
MeAgain
Focused shot logging with reminders, AI-assisted food logging, protein and water tracking, and progress photos in one dashboard. Cleanly built.
Platforms
iOS + Android
Price
Freemium; Unlimited tiers $39.99 to $119.99
+
Strengths: low-friction shot logging; AI food logging; built-in protein and water; estimated medication-level view; clean UI for a new patient; on both iOS and Android.
−
Limitations: newer with a smaller review base; no bloodwork.
Best for: someone who wants the basics without overload.
5
GLP1 Tracker (Tirzepatide)
Focused specifically on tirzepatide, or tirz (Mounjaro and Zepbound). Injection logging, side effects, weight, protein, and water in a small, focused app. iOS-only with a small review base - worth a look if you're on tirzepatide and want an app built around it.
Platforms
iOS only
Price
Freemium; $9.99/mo, $39.99/yr, or $79.99 lifetime
6
DoseDiary
A lightweight web app for simple dose scheduling and progress. Nothing to install. Web-only means no native shot notifications and no health-app sync - better as a quick try than a long-term home.
Platforms
Web (dosediary.app)
Price
Free + premium (site does not list prices)
7
GlucoPal / Zepbound Tracker
This developer publishes separate app listings targeting specific medications (Zepbound, Wegovy, Mounjaro variants). Easy to find if you search for your exact drug - but multiple listings for what appears to be the same underlying product is a caution flag. Check the "last updated" date and recent reviews before committing.

Head-to-heads
Shotsy vs Glapp
Shotsy is a native GLP-1 app on iOS and Android: shot reminders, injection sites, weight, side effects and food logging, with the medication-level chart on its paid tier. Glapp is a native app (iOS, Android, and web) built around one thing: an estimated medication-level view compared against clinical-trial data, which Regimen also shows. Different tools for different jobs. Shotsy is the day-to-day home; Glapp is a supplement. Neither connects that curve to your side effects, weight and labs the way Regimen does.
MeAgain vs Shotsy
MeAgain is a clean, focused app for a new GLP-1 patient who just wants to log the shot, drink enough water, and hit a protein target - now on both iOS and Android, with an AI-assisted food logger and its own estimated medication-level view. Shotsy is the bigger, more established option, with a longer feature list. If a nervous first-week patient is looking for the least intimidating option, MeAgain is that. If they want the one that has been around the longest, it's Shotsy. Both fall short on connecting your dose to your side effects and weight over time.
Shotsy vs GlucoPal
Shotsy is one polished app that handles Ozempic, Wegovy, Mounjaro, and Zepbound in a single tracker. GlucoPal's developer ships separate app listings per medication, which makes the app easy to find in a store search but creates confusion about which listing is actively maintained. Shotsy is the more coherent product; GlucoPal is easier to find if you searched your exact medication by name. Neither gives you the medication-level chart free.
How to pick the right GLP-1 app
“I want a full-featured tracker for free”
Regimen is free for one medication, including the medication-level curve, plus a 14-day trial.
“I want the one that has been around the longest”
Shotsy, with built-in food logging. Premium runs $9.99 to $19.99/mo or $39.99 to $59.99/yr depending on tier.
“I'm on Android”
Regimen, Shotsy, MeAgain, and Glapp all have Android apps. GLP1 Tracker and GlucoPal are iOS-only.
“I just want the medication-level chart, free”
Regimen, which includes the chart free and connects it to your own daily markers, reminders, and side effects; or Glapp if you want a standalone pharmacokinetic visualizer (iOS, Android, and web).
One medication free, plus a 14-day trial. Reminders, injection sites, weight, side effects, and your med-level curve. Coming from Shotsy? Import your history in one tap.
Frequently Asked Questions
Do I really need a GLP-1 tracker app?
Yes. The shot takes ten seconds; the six days after it are where the side effects, the appetite changes and the results happen. A good tracker follows the titration plan your doctor set, shows you where you are as the medication builds, records how your body is responding in enough detail to fit you, and turns all of it into something you can show your doctor. That's the difference between hoping it's working and knowing.
What's the best app for tracking semaglutide (Ozempic/Wegovy)?
Regimen is the better pick if you want the medication-level curve free and your bloodwork next to your doses, and it's completely free for a single compound. Shotsy has the larger user base and built-in food logging. Both are cross-platform.
What's the best app for tracking tirzepatide (Mounjaro/Zepbound)?
GLP1 Tracker is built specifically around tirzepatide. Shotsy and Regimen both support tirzepatide tracking as well. Both show medication-level charts. Regimen includes it free and reads your side effects and bloodwork against your dose changes; Shotsy adds food logging and has the larger community.
Can I track peptides and GLP-1s in the same app?
Regimen is the only app on this list that supports both. If you're taking MOTS-c alongside semaglutide, or KLOW while on tirzepatide, Regimen tracks all of it on one timeline with a library of 200+ compounds and brands.
Which app is best for tracking injection sites?
Regimen offers injection site tracking with automated rotation suggestions. Shotsy also tracks injection location. For GLP-1 medications, you're typically alternating between abdomen, thigh, and upper arm.
Are web apps like Glapp and DoseDiary reliable enough?
For visualization and data logging, yes. For injection reminders, a browser-only tool like DoseDiary can't send native push notifications reliably. Glapp also ships native iOS and Android apps, which handle reminders normally.
How do I track my GLP-1 titration schedule?
Regimen offers a free titration planner on its website that maps out your dose increases over time. If you're using a different app, log each dose change with the date so you can look back and see how side effects correlated with each step up.
Is Regimen really free for GLP-1 tracking?
Yes. One compound costs nothing, and there is a 14-day trial of the rest. The half-life visualizer, correlation charts, injection site tracking, Apple Health sync, and reconstitution calculator are all included. You only pay if you want to track multiple compounds.
Can any of these apps tell me what dose to take?
No, and they shouldn't. These are tracking and calculation tools, not medical advice platforms. Dosing decisions should come from your prescriber or your own research and provider guidance.
What's the best GLP-1 tracker app in 2026?
The best free GLP-1 tracker app in 2026 is Regimen; Shotsy has been around the longest; Glapp is the standalone medication-level chart. Regimen is free for tracking one medication.
Is there a free GLP-1 tracker app?
Yes. Regimen is free for tracking one medication - weekly shot reminders, injection-site rotation, weight and progress photos, detailed side-effect logging, and the estimated medication-level curve. No trial timer, no credit card. The Premium tier only matters if you later want to track more than one medication.
Is there a GLP-1 tracker app for Android?
Regimen, Shotsy, and MeAgain are all on iOS and Android. Glapp is a native app on iOS, Android, and web (with Apple Health). DoseDiary is web-only. GLP1 Tracker and GlucoPal are iOS-only. If you're on Android, Regimen, Shotsy, MeAgain, and Glapp are all options.
Which GLP-1 app shows your medication levels for free?
Regimen. The estimated medication-level curve - the chart that shows how much semaglutide or tirzepatide is in your system between weekly shots - is included free; Glapp's free tier shows one as well. Shotsy has the same feature but puts it behind its paid tier, which starts at $9.99/mo or $39.99/yr.
Do these apps work if I'm on an oral GLP-1 pill instead of a shot?
Yes. Most of these trackers, Regimen included, let you log a daily pill instead of a weekly shot, so dose schedule, side effects, and weight tracking still work (injection-site tracking just won't apply). Most people on a GLP-1 are on a weekly injection, which is what these apps are built around, but a daily pill logs fine.
I'm on compounded semaglutide and reconstitute it myself. Can these apps help with the math?
Regimen has a built-in reconstitution calculator (also free on the web) if you're mixing compounded semaglutide from a vial. Most mainstream trackers don't, since they assume a pre-filled pen. On a standard Ozempic, Wegovy, Mounjaro, or Zepbound pen, you can ignore this.
Can I track GLP-1 side effects?
Yes. Regimen logs the common ones - nausea, constipation, fatigue, appetite changes - and the ones most apps skip, like sulfur burps and water retention, and maps them against your dose so you can see whether the side effect got worse at your last titration step. Not medical advice. This is an app-comparison article for people already on or considering a GLP-1 medication under a clinician's care.
Is the free GLP-1 tracking real, or is it a trial that expires?
It is real. Regimen is free for one medication with no timer and no credit card, so if you are on a single GLP-1 you can use it free indefinitely. The 14-day trial is separate: it exists so you can try tracking more than one compound before deciding on Premium.
What is the best free app to track GLP-1 shots?
Regimen. Tracking one medication is free: weekly shot reminders, injection-site rotation, side-effect logging, and weight synced from Apple Health or Health Connect. Shotsy is the best-known GLP-1-only alternative; its core tracking is free, though the medication-level chart is paid.
Is there a free app that can track Mounjaro medication?
Yes. Regimen tracks Mounjaro free, including all six titration doses, with a reminder before each weekly shot and a log of which injection site you used. Zepbound and compounded tirzepatide work the same way.
What is the best GLP-1 tracker app for iPhone?
Regimen, if you want your shots, side effects, weight and bloodwork in one app with the medication-level curve included free. Shotsy and MeAgain are both solid on iPhone too. All three are free to start.
How do MeAgain, Shotsy, and Glapp compare?
Shotsy has the longest track record and medication-level charts on its paid tier. MeAgain is food-first, five ways to log meals with side effects on the same timeline. Glapp runs on iOS, Android, and the web, useful if you want a big-screen view. All three are GLP-1-only. Regimen's edge against all three is the free medication-level curve and bloodwork logged next to your doses.
Which GLP-1 tracker do Reddit users recommend?
The GLP-1 subs debate this constantly; a recent r/Zepbound thread asking which GLP-1 app is best drew 40 replies. Threads are the best place to hear how an app holds up week to week; this page is for what each one does and what it costs.
Can I split my weekly dose, microdose, or dose on specific days?
Yes. Regimen lets you set the exact days for each shot, split a weekly dose into two injections about 3.5 days apart, and log smaller, more frequent doses at any amount if you microdose. Schedules are set per compound, so the app follows the plan you and your prescriber chose instead of a once-a-week template. Dosing on specific days is the reason one Shotsy user switched to Regimen.
What's the best app for GLP-1 weight loss?
Regimen. It does the weight-loss basics every tracker does, weight, body fat and progress photos, and then does the part most of them skip: it holds your titration schedule and steps you up on plan, logs the side effects that decide whether you can stay on a dose, and shows your medication level between shots so a slow week has an explanation instead of a guess. Free for one medication, on iPhone and Android. Shotsy is the established alternative and adds food logging.
Is there a free app to track GLP-1 weight loss?
Yes. Regimen is free for one medication, and that covers a single GLP-1 properly: doses and reminders, injection-site rotation, weight loss and progress photos, side effects, lab work, and the medication-level chart most apps put behind a subscription. Glapp has a free tier and is good at the medication-level view, but it has no titration schedules and no lab work.
What's the best GLP-1 app?
Regimen, for most people. Any GLP-1 app will log the shot and remind you about the next one. What separates them is whether the app follows the plan you were given and shows you what the medication is doing: a titration schedule that steps you up on its own, side effects logged in enough detail to tell a settling week from a dose you can't stay on, your medication level between shots, and your labs on the same timeline. Regimen does all of that and is free for one medication on iPhone and Android. Shotsy has been around the longest and has food logging. Glapp is free and good if all you want is the medication-level view.
Which GLP-1 tracking app works on both iPhone and Android?
Regimen, Shotsy, Glapp and MeAgain are all on both. GLP1 Tracker and GlucoPal are iPhone only, and DoseDiary runs in a browser rather than as an app. If you switch phones or share tracking with someone on the other platform, that narrows the list to four before you compare anything else.
