Best GLP-1 Tracker App for UK Users in 2026
Track the 12-week NHS Wegovy checkpoint, dose titration, and side effect patterns with the best GLP-1 apps for UK users in 2026.
If you are on the NHS Tier 2 Wegovy pathway, tracking is not optional. It is the evidence your specialist needs to confirm you have hit the 5% weight loss threshold at 12 weeks. Without that documentation, you lose access. The right app makes that documentation automatic.
Even if you are on Mounjaro through an NHS diabetes pathway or self-paying through a private clinic like Slimming Clinic or Voy Health, tracking your dose progression, injection dates, and weight trends keeps you in control of a protocol that requires active management. Side effect patterns during titration matter too: knowing when GI symptoms typically hit in your weekly cycle helps you schedule around them.
This guide covers the four best options available to UK GLP-1 users in 2026. For the full comparison of all 7 tracker apps, see the complete GLP-1 Tracker App Guide.
The Quick Answer
Regimen is the best GLP-1 tracker app for UK users who need more than a weight log. The combination of injection scheduling, dose titration tracking, and health correlation charting covers everything the NHS 12-week checkpoint requires.
For users who want the most popular dedicated GLP-1 app and do not need multi-compound tracking, Shotsy is a strong alternative. It dominates app store reviews for GLP-1 specifically and has the medication level chart most NHS users will recognise from the Wegovy program. Regimen edges ahead if you are tracking multiple compounds (for instance, if you are also taking Mounjaro for T2D alongside other medications).
The Top 4 Apps, UK-Framed
1. Regimen: Best overall for UK users tracking multiple compounds
iOS and Android. Free for one compound, GBP 3.99/month (roughly) for multi-compound tracking. 4.9 stars (70+ reviews).
Regimen logs injection date, dose, and body weight, and lets you track symptom patterns (nausea, energy, appetite) alongside your medication schedule. The correlation charts are particularly useful for the NHS 12-week checkpoint: you can see your weight trend line relative to injection history in a format that is easy to screenshot and share with your prescriber. For users on Mounjaro alongside other medications or a complex protocol, multi-compound support in one place is the main advantage.
2. Shotsy: Best for Wegovy-focused tracking
Ready to track your protocol?
- Smart reminders so you never miss a dose
- Progress tracking with photos and weight
- Medication level curves for every compound
iOS and Android. Freemium with a $9.99/month premium tier (approximately GBP 7.90). 4.85 stars across 19,802 reviews.
Shotsy is the dominant GLP-1 tracker by review volume. The medication level charts map your dose progression clearly, and it covers both Wegovy and Ozempic protocols. Most UK users on the Wegovy NHS pathway will find everything they need in Shotsy's free tier. The review count means the feature set is well-tested and reliable. The subscription cost is higher than Regimen's if you need the full feature set.
3. Glapp: Best free option with PK visualisation
Web-only. Free.
Glapp runs in your browser without an app install. It offers pharmacokinetic visualisation and food noise tracking specifically built for GLP-1 users. No iOS or Android app means no push reminders, which is a real limitation for injection scheduling. But if you want free PK visualisation with no subscription, it works.
4. GLP1 Tracker: iOS-only option for tirzepatide users
iOS only. Freemium. 4.7 stars across 61 reviews.
GLP1 Tracker is focused on tirzepatide (Mounjaro) protocols. If you are on Mounjaro through the NHS for T2D or using a private clinic, this app covers tirzepatide's specific dose steps well. iOS only, which rules it out for Android users.
Why NHS Tracking Matters
The NHS Tier 2 Wegovy pathway has a hard checkpoint at 12 weeks. You need to show at least 5% body weight loss relative to your starting weight to continue receiving Wegovy on the programme. If you cannot document that threshold, access stops.
A tracker app makes this straightforward. You log your starting weight when you begin, weigh in weekly, and by week 12 you have a clean chart showing your trajectory. That chart is your evidence.
Beyond the 12-week threshold, ongoing weight tracking supports continued NHS access at subsequent review points. The NHS programme does not just check once. It expects continued progress, and documented trends are how you demonstrate them.
For users on Ozempic for T2D or Mounjaro for T2D through standard NHS prescribing (not the Tier 2 weight pathway), tracking still matters for your GP conversations. A dose titration log shows your GP whether you have been tolerating up-titrations well or whether GI side effects are clustering around specific dose increases.

Frequently Asked Questions
Does tracking help with NHS Wegovy continuation at 12 weeks?
Yes. The NHS Tier 2 pathway requires documented 5% weight loss at 12 weeks to continue. A tracking app gives you a clean weight log from day one. Showing your specialist a consistent weight trend rather than trying to recall numbers from memory makes the review appointment straightforward.
Is Regimen available on Android in the UK?
Yes. Regimen is available on both the iOS App Store and Google Play Store. Several competitors (OptiPin for TRT, GLP1 Tracker) are iOS only or have weaker Android versions. Regimen and Shotsy both work well on Android.
Can I track Mounjaro and Ozempic in the same app?
In Regimen, yes. You can track multiple compounds in the multi-compound tier. If you are switching from Ozempic to Mounjaro (a common switch as Mounjaro availability improves), Regimen lets you maintain a single continuous log across both.
What's the best free GLP-1 tracker for UK users?
Regimen's free tier covers single-compound tracking with injection logging and reminders. Glapp is a free web option with PK visualisation. Shotsy has a free tier with the most features. For most NHS Wegovy users, Shotsy's free tier or Regimen's free tier will cover what the 12-week checkpoint needs.
Does Regimen track food noise reduction?
Yes. You can log appetite and hunger levels as tracked health metrics in Regimen, and the correlation charts show you how those patterns change relative to injection schedule and dose level.
Track your GLP-1 protocol with Regimen. Wegovy, Ozempic, and Mounjaro supported. Weight trends, dose titration, and side effect patterns. Free for one compound.
