Best GLP-1 Tracker App for UK Users in 2026

Updated October 26, 2026

What changed: GlucoPal replaces GLP1 Tracker; re-checked every app's listing and platforms.

Quick answer

What is the best Mounjaro tracker app in the UK? Regimen is the most complete GLP-1 tracker for UK users: 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 and water logging. Glapp has a free tier and compares your progress with clinical trial results. GlucoPal is a Mounjaro log with a meal scan, on iPhone and Android.

We make Regimen, so this list isn't neutral. We've used many of these apps ourselves, and every entry is checked against its own App Store and Google Play listing (October 26, 2026).

Methodology

How We Evaluated These Apps

We compared every GLP-1 tracker available to UK users against its own App Store or Google Play listing and official site.

Titration schedules

Whether the app holds the plan you were given and steps you up on schedule, or leaves you to remember which week you are in.

Side effect tracking

Nausea, constipation, reflux, fatigue, hunger and food noise coming back. They cluster after a step-up, and how they move is what tells you whether a rough week was the medication settling or a dose you cannot stay on.

Medication level charts

Whether you can see the curve come down before your next shot, which is usually why day six feels different from day two, and whether it costs extra.

Progress tracking

Weight is one part. Body fat, resting heart rate, blood pressure and sleep keep moving while the scale does not, and photos are the record people wish they had started.

Injection site tracking

Whether it suggests the next site and lets you add your own spots.

Supply tracking

Whether it knows what you have on hand, when a pen expires, and when to reorder.

Lab work

Bloodwork on the same timeline as your doses, which matters more if you are on this for type 2 than for weight.

Reports for your provider

One document with your doses, your symptoms and your trend in it.

The Apps Reviewed

1

Regimen

Regimen tracks the medication and what it is doing to you, not just the day you took it.

Pricing

Free for one medication, with no time limit and no card. Premium covers more than one. iOS and Android.

Best for

Anyone on an NHS pathway with a review to prepare for, and anyone tracking more than one compound.

Strengths

  • + Your titration plan, followed for you. Set it once and it steps you up on schedule, with the week's dose in the reminder.
  • + Side effects in detail. Over 50 daily markers you choose yourself, on the same timeline as the dose, so a rough fortnight has a shape.
  • + The medication-level curve, free. See it come down before your next shot, which is usually why day six feels different from day two.
  • + Weight, body fat, resting heart rate, blood pressure and sleep, pulled in from Apple Health or Health Connect, plus progress photos side by side.
  • + Bloodwork on the same timeline, 25+ markers scanned from the report.
  • + A one-page report with your doses, symptoms and weight trend for your review.

Trade-offs

  • − No food logging. Most people already have an app for that.

Verdict: The one that turns twelve weeks of taking it into something you can show a prescriber.

2

Shotsy

Shotsy is a GLP-1 shot log that has been around longer than anything else here, with food and water logging built in.

Pricing

Free tier, paid tier beyond it. iOS and Android.

Best for

Someone who wants calories and water in the same app as the shot.

Strengths

  • + Built-in calorie, protein and water logging.
  • + Weight, body fat, lean mass, waist and glucose.
  • + Automatic injection site rotation.
  • + A PDF summary to share.

Trade-offs

  • − The medication-level chart is on the paid tier.
  • − You plan the titration yourself; nothing advances it.
  • − No lab work.

Verdict: A polished log with food tracking attached. Everything after the shot is thinner.

3

Glapp

Glapp is a GLP-1 tracker with a free tier, known for comparing your progress with clinical trial results.

Pricing

Free tier; Glapp Max is optional. iOS, Android and web.

Best for

Seeing your estimated level between shots without paying.

Strengths

  • + The medication-level chart, free.
  • + Runs in a browser as well as on both phones.
  • + Vial volumes and beyond-use dates.

Trade-offs

  • − No lab work.

Verdict: Does one thing well and gives it away. Worth having if that one thing is what you want.

4

GlucoPal

GlucoPal is a GLP-1 tracker for iPhone and Android, listed in the UK App Store as Mounjaro Tracker.

Pricing

Free core; the medication-level chart and PDF reports are on GlucoPal Pro. iOS and Android.

Best for

Logging Mounjaro doses, weight and photos, with a meal scan.

Strengths

  • + Dose-escalation steps.
  • + Automatic injection site rotation.
  • + Weight, progress photos and a meal scan.

Trade-offs

  • − The medication-level chart is on the paid tier.
  • − No lab work or supply tracking listed.

Verdict: A Mounjaro log with a meal scan. The medication-level chart costs extra.

Frequently Asked Questions

Does tracking help with NHS Wegovy continuation at 12 weeks?

Yes, and it is the most practical reason to bother. The Tier 2 pathway needs at least 5% of your starting body weight lost by week 12 to continue. If you logged your starting weight and weighed in weekly, that is a chart you can show. If you did not, you are relying on whatever the scales say on the day.

Is Regimen available on Android in the UK?

Yes, on both iPhone and Android with the same features on each. Shotsy, Glapp and GlucoPal are on both too.

Can I track Mounjaro and Ozempic in the same app?

Yes. Regimen holds both, each on its own schedule with its own dose history and its own medication-level curve, which matters if you switch or overlap during a change. The free tier covers one medication; more than one needs Premium.

What's the best free GLP-1 tracker for UK users?

Regimen is free for one medication with no time limit and no card, and that includes the medication-level curve, side-effect tracking and the weight trend. Glapp has a free tier as well, with a medication-level view and a comparison of your progress with clinical trial results.

Does Regimen track food noise reduction?

Yes. Food noise is one of the 50-plus daily markers, logged against the dose you were on, so you can see whether it eased after a step-up or came back toward the end of the week. Glapp tracks food noise too.
