Best GLP-1 Tracker App in 2026:7 Free & Paid Apps for Ozempic, Wegovy, Mounjaro & Zepbound

If you take the same dose every week and never have side effects, a phone alarm works fine. But most people titrate doses over months, experience side effects that shift at each level, and want to see their weight trend alongside medication changes. A tracker turns scattered data into a clear picture of what's working. A dedicated GLP-1 shot tracker replaces all of that with one log.

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.

GLP1 Tracker is built specifically around tirzepatide. Shotsy and Regimen both support tirzepatide tracking as well. The decision comes down to whether you need multi-compound tracking (Regimen) or medication level charts (Shotsy).

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.

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.

For visualization and data logging, yes. For injection reminders, no. Web apps can't send native push notifications reliably.

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.

Yes. One compound costs nothing, and there is a two-week 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.

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.

The best free GLP-1 tracker app in 2026 is Regimen; the most established paid option is Shotsy; the best free medication-level visualizer is Glapp. Regimen is free for tracking one medication with every feature unlocked, including the medication-level curve.

Yes. Regimen is free for tracking one medication with every feature unlocked - 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 $4.99/mo Pro tier only matters if you later want to track more than one medication.

Regimen, Shotsy, and MeAgain are all on iOS and Android. Glapp is a native app on iOS, Android, and web (with Apple Health and Health Connect on Android). DoseDiary is web-only. GLP1 Tracker and GlucoPal are iOS-only. If you're on Android, Regimen, Shotsy, MeAgain, and Glapp are all options.

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. Shotsy has the same feature but puts it behind its $9.99/mo or $39.99/yr premium tier.

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.

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.

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.

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 two-week trial is separate: it exists so you can try tracking more than one compound before deciding on Pro.

Regimen. Tracking one medication is free with everything unlocked: 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.

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.

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.

Shotsy goes deepest on dose analytics and medication-level charts. 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.

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.

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.

Yes. Export your data from Shotsy first, then in Regimen open Settings, choose Data, then Import, and follow the steps. Your dose history comes across with the original dates. Import once only; a second import doubles your doses.
